How the platform works
What is a public-data building report?
Enter a UK commercial building address to preview a report from available public records. Create a free account to unlock the full report, save it and access the PDF. No bills or payment are needed to start.
The report checks for an address-matched non-domestic EPC and regional climate and grid context. Outdoor-air information depends on a configured licensed source. Coverage and freshness vary; a regional reading is not a measurement inside your building.
Check that the address and building details are correct. Missing or uncertain records should be treated as gaps. Add bills and operating details later for building-specific analysis.
How does the AI bill analysis work, from upload to report?
You upload a bill as a PDF or a photograph. The document is read by AWS Bedrock, which locates the supplier, the meter or MPAN reference, the billing period, the consumption in kWh, the unit rate, the standing charge and every additional line item. Scanned and photographed bills are handled as well as digital ones, because the page is read as an image rather than parsed against a fixed template. That matters in practice, since most bills that reach a facilities desk have been through a scanner or a phone camera at least once.
The extracted figures are then set against the building's own profile. Floor area comes from the EPC, occupancy type from the property record, regional grid data from the postcode, climate normals for the exact period from NASA POWER, and prior consumption from any earlier bills on the account. That comparison is what turns a bill into information. Consumption that looks unremarkable on its own becomes a finding once it is well above the benchmark for a building of that size, in that use class, in that region, in that season.
The system then looks for specific, nameable waste: a unit rate above the current market range, a standing charge out of line with the contract type, capacity charges for capacity the building does not draw, reactive power penalties, estimated readings carried for months without an actual read, Climate Change Levy or VAT applied at the wrong rate, and baseload consumption that does not fall when the building is closed.
Every finding is expressed in kWh and pounds, and every one is cited to the line item it came from. Nothing is reported as a percentage improvement without the underlying figure behind it. If a saving cannot be traced back to something printed on a document you already hold, it does not go in the report.
What data sources does Algi use and how current are they?
The public report uses available building records and regional context. An EPC describes the assessed building at the certificate date; it is not a current meter reading. Climate, grid and outdoor-air context describe their stated region and period.
Check the source and date alongside each finding. Availability varies by address, licensing and service response. A missing EPC or unavailable feed does not prove that a building performs well or poorly.
Your own bills and confirmed property details add evidence. A benchmark or calculation must be distinguished from a measured value, with its assumptions stated.
How does energy benchmarking work?
Energy Use Intensity, usually shortened to EUI, is annual energy consumption divided by floor area, expressed in kWh per square metre per year. It is the standard way to compare buildings that are not the same size. A 20,000 square metre office using more total energy than a 4,000 square metre office tells you nothing on its own. The same two buildings compared at 190 and 340 kWh per square metre tells you a great deal.
Algi benchmarks against three reference sets. The first is CIBSE TM46, the benchmark category set behind Display Energy Certificates, which gives a typical annual figure for each of 29 building activity types. The second is the building's own characteristics as recorded on the EPC: floor area, built form, main heating fuel and construction age band, which qualify the comparison so that a 1960s naturally ventilated office is not judged against a new air-conditioned one. The third is the anonymised Algi client dataset, which grows as more buildings are analysed and is the only one of the three that reflects what comparable buildings are actually doing this year rather than what a published benchmark says they should be doing.
For context, the average UK office sits at roughly 273.9 kWh per square metre per year across all fuels. That number is a starting position, not a verdict. A building well above it may have a good reason, such as a data hall, a commercial kitchen or extended operating hours, and the brief says so wherever the public record shows it.
Benchmarks are recalculated every time a bill is processed, so the position moves as the building's own consumption record lengthens and as the comparison set grows. A building that sat in the worst quartile on public data alone frequently moves once real consumption is in, and it moves in both directions.
What file formats can I upload for bill analysis?
PDF, JPEG and PNG. Multi-page PDFs are supported and are the common case, since most commercial supply bills run to several pages of line items behind a one-page summary. Up to ten documents can be submitted in a single analysis session, which is how a full quarter across gas, electricity and water is usually loaded.
The minimum information needed for a useful analysis is the supplier, the billing period, the consumption in kWh, and the cost. With those four a bill can be benchmarked, rate-checked and compared against the building profile. A bill showing cost but no kWh can still be checked for rate and charge anomalies, but it cannot be benchmarked, and the report states which of the two you are getting.
For photographed bills the practical requirement is only that the numbers are legible to a person: the whole page in frame, in focus, and without a fold running through the consumption table.
Is my data secure?
Data is stored in the United Kingdom, in the AWS eu-west-2 London region, and stays there. It is encrypted in transit and encrypted at rest. Access is controlled at row level, so an account can read only the properties, bills and reports that belong to it.
Bills are processed by AWS Bedrock inside the same AWS account and the same region. They are not sent to a third-party AI service, they do not leave the infrastructure Algi controls, and they are not used to train any model. That is the reason Bedrock is used rather than a public API endpoint: the processing happens inside the boundary the data is already in.
Uploaded bill files are deleted from storage once the report has been generated. The figures extracted from a bill are retained, because they are what the benchmark history, the trend chart and any later SECR aggregation are built from. The source document itself is not kept.
The anonymised benchmark dataset described above carries no client identity, no address and no company name. It holds building characteristics and consumption intensity only, which is what makes a comparison possible without exposing anybody's figures.
Can I export my data?
Yes. Reports export as PDF, the underlying figures export as CSV, and API access is available on Enterprise for organisations that want to pull the data into their own reporting stack or asset management system.
All data belongs to the client. That is not a courtesy position. A compliance record you cannot take with you is not a compliance record, because the obligation stays with the filer whatever happens to a supplier relationship.
Exported reports carry the methodology statement with them, stating what was measured and what was modelled, which source each figure came from, and which conversion factor set and publication year were applied. An auditor, an assessor or a board reviewer reading the export a year later can see the provenance of every number without having to come back and ask.
What happens if I cancel?
Data is retained for 90 days after cancellation and is then deleted. The 90 days exist so that nothing is lost while an export is arranged or a reporting year is closed out. Export everything you need before that window ends, because the deletion is final.
Leased hardware is collected. There is no charge for collection and no dilapidation claim for normal use. Units are collected, not written off against the client.
There are no exit fees and no minimum term beyond the billing period already in progress. The reasoning is straightforward. If the platform is not finding more than it costs, stopping should be easy, and the alternative is a business that depends on lock-in rather than on results.
SECR compliance
What is SECR and who needs to report?
SECR stands for Streamlined Energy and Carbon Reporting. It was introduced by the Companies (Directors' Report) and Limited Liability Partnerships (Energy and Carbon Report) Regulations 2018 and applies to financial years starting on or after 1 April 2019. The disclosure is not a standalone document. It sits inside the Directors' Report, which is filed at Companies House as part of the annual accounts.
Three groups are in scope: quoted companies of any size, large unquoted companies, and large LLPs. A company is large for this purpose if it meets two of three Companies Act criteria: 250 or more employees, turnover above a monetary threshold, or a balance sheet total above a monetary threshold. Those two monetary thresholds were uprated for financial years beginning on or after 6 April 2025, from GBP 36 million turnover and GBP 18 million balance sheet to GBP 54 million and GBP 27 million. A company reporting on an earlier year is tested against the lower pair, which is why both sets of figures are still quoted in circulation.
There is one practical exemption. An organisation that consumed 40,000 kWh or less across the reporting year states that fact in the Directors' Report instead of making the full disclosure. Very few commercial buildings of any size fall under it, and a group that qualifies has to satisfy itself of the figure rather than assume it.
Group structures report at the parent level, with the parent disclosing on behalf of itself and its subsidiaries. Subsidiaries that are themselves large can be exempt from reporting separately where they are included in a parent group report.
What does a SECR report contain?
Four elements are required. The first is total energy consumption for the year in kWh, covering purchased electricity, gas and transport fuel. The second is greenhouse gas emissions, expressed in tonnes of carbon dioxide equivalent, covering Scope 1 combustion, Scope 2 purchased electricity, and the mandatory slice of Scope 3 that relates to business travel in employee-owned or leased vehicles where the company is responsible for buying the fuel. The third is at least one intensity ratio, a normalised figure that lets a reader compare the year against the last one. The fourth is a narrative describing the energy efficiency actions taken during the reporting year.
Emissions are converted from consumption using the UK Government conversion factors published each year by DEFRA and now maintained by DESNZ. The factor set is version-dated, and using the wrong year's factors is one of the more common errors in a first SECR filing, because the electricity factor in particular moves noticeably from year to year as the generation mix changes.
Prior-year comparatives are required from the second year of reporting onward, so the first year establishes a baseline and every year after it is a comparison. The report must also state the methodology used, which is normally a named standard such as the GHG Protocol, together with an explanation of any figure that has been estimated rather than metered.
The intensity ratio is the element that gets least attention and does most work. A ratio per square metre suits a property portfolio, per employee suits a service business, and per unit of turnover suits a group with mixed operations. The choice is the company's, but it should stay consistent between years, because a ratio that changes basis annually cannot show a trend.
Does SECR require third-party accreditation?
No. SECR has no accredited assessor requirement and no mandatory external verification. This is the single largest practical difference between SECR and ESOS, and it is regularly misunderstood, usually by organisations that have been quoted a consultancy fee on the assumption that one is required.
Responsibility for the data sits with the company's directors, because the disclosure forms part of the Directors' Report they sign. That responsibility cannot be transferred to a consultant or a software supplier. A tool such as Algi can gather the consumption data, apply the conversion factors, calculate the intensity ratio and format the disclosure for inclusion in the report, but the obligation stays with the filer.
Some companies choose voluntary assurance anyway, usually where an investor, a lender or a parent group asks for it. That is a commercial decision rather than a regulatory one, and it is worth being clear about which of the two is driving the spend before agreeing to it.
How does Algi generate SECR reports?
Algi can aggregate recorded energy consumption and costs from uploaded bills by property and period. Check source documents, missing periods and duplicate or overlapping bills before using those totals.
A complete SECR disclosure may also require organisation-wide data, transport, emissions calculations, intensity ratios, methodology, prior-year comparisons and an efficiency narrative. A building report alone does not establish that the disclosure is complete.
Confirm available outputs and review responsibilities with Algi and your reporting adviser. Directors remain responsible for the annual reporting.
What is the penalty for non-compliance with SECR?
The immediate exposure is the Companies House late filing penalty, which runs from GBP 150 to GBP 7,500 depending on how late the accounts are and whether the company is private or public. A Directors' Report that omits required SECR content can be rejected, and a rejected filing that is then re-submitted after the deadline attracts the penalty as if it had simply been late.
Beyond the fine, failure to comply with the Companies Act reporting requirements is an offence on the part of the directors rather than the company, which is a materially different kind of exposure from a filing fee. Public companies face the higher end of the penalty scale, and penalties double where accounts are late in two consecutive years.
In practice the commercial consequences arrive before the regulatory ones. A missing or thin SECR disclosure is visible to anyone who pulls the accounts, which increasingly includes procurement teams, lenders and prospective clients running supplier due diligence.
How does SECR relate to UK SRS?
SECR and UK Sustainability Reporting Standards have different scopes. A building energy report is only one possible input to wider organisational sustainability reporting.
Check current UK government and regulator requirements for your organisation and reporting year. Publication of a standard does not, by itself, make it mandatory for every company.
Confirm your reporting obligations and implementation timetable with your adviser before commissioning a report.
ESOS compliance
What is ESOS Phase 4 and when is the deadline?
ESOS is the Energy Savings Opportunity Scheme, a mandatory four-yearly energy assessment for large UK organisations, administered by the Environment Agency. Phase 4 has a qualification date of 31 December 2026 and a compliance deadline of 5 December 2027. An organisation is assessed against the qualification date, and the audit covers the twelve months of energy use running up to it.
The assessment must account for total energy consumption across buildings, transport and industrial processes, and the audits themselves must cover at least 90 per cent of that total. The remaining 10 per cent can be set aside as a de minimis, which is what allows a small outlying site or a marginal fuel to be excluded without invalidating the assessment. Choosing what falls in that 10 per cent is a judgement the Lead Assessor signs off on, not an administrative rounding.
Phase 4 also carries the obligations added after Phase 3: an action plan setting out what the organisation intends to do about the opportunities its audit identified, and annual progress updates against that plan. The scheme has moved from an audit you file and forget toward a cycle you report against, which changes what a compliant organisation needs to have in place between deadlines rather than just at them.
The practical timing point is that the qualification date and the compliance deadline are eleven months apart, and the audit must cover a twelve-month reference period ending on or before the qualification date. Organisations that start collecting energy data after the qualification date are already reconstructing history rather than reading it.
Who qualifies for ESOS?
A UK organisation qualifies if, on the qualification date, it employs 250 or more people, or it has both an annual turnover above GBP 44 million and an annual balance sheet total above GBP 38 million. An organisation that is part of a corporate group where any member qualifies is brought into the scheme with it.
It is worth being precise about the difference between this test and the SECR one, because they are frequently conflated. SECR uses the Companies Act large-company test, which is two out of three criteria. ESOS uses its own thresholds, with an "or" between the headcount limb and the financial limb, and the financial limb requires both the turnover and the balance sheet figures to be exceeded. An organisation can therefore be in scope for one and not the other.
Group structures are assessed at the highest UK parent level. The parent is responsible for compliance across the group, and the whole group's energy consumption is in scope, though participants can choose to disaggregate and comply separately where that suits the structure. Overseas parents do not pull a UK group out of scope, and the highest UK entity carries the obligation.
Does ESOS require an accredited assessor?
Yes. Unlike SECR, an ESOS assessment must be reviewed and signed off by a Lead Assessor registered with an approved professional body, such as CIBSE, the Energy Managers Association, IEMA or an equivalent register. The assessment is also signed off at board level by a director, so there are two signatures on it and they cover different things.
The Lead Assessor's review is not a rubber stamp on a finished report. They examine the data, the methodology, the sampling approach and the reasoning behind the opportunities identified, and they are professionally accountable for the conclusion. That is why the quality and completeness of the underlying data has such a direct effect on how long the review takes and what it costs.
The one exception is that an organisation certified to ISO 50001 covering its total energy consumption can use that certification as its compliance route rather than commissioning ESOS audits, though it still notifies the Environment Agency.
How does Algi help with ESOS?
Algi can help organise available bill and building evidence for an assessment. Coverage depends on the records supplied; the platform cannot infer a complete organisation-wide energy record from a single property.
A registered Lead Assessor can identify the required energy coverage, site work, gaps and opportunities. Agree the assessment route, deliverables and fees before relying on the data pack.
For qualification, deadlines and assessment routes, use the Environment Agency ESOS guidance.
How much does an ESOS audit typically cost?
A full standalone ESOS engagement typically costs between GBP 8,000 and GBP 15,000, with multi-site organisations and complex estates at the upper end and beyond it. Spread across the four-year cycle, that is roughly GBP 2,000 to GBP 3,750 a year, which is how it should be read when comparing it against an annual subscription.
The spread in that range is mostly explained by data readiness rather than by building count. Two organisations with the same number of sites can pay very different fees depending on whether the consumption record exists or has to be built from scratch, and the second case is the common one.
With Algi preparing the data pack, the assessor's review is substantially faster, and the fee through the advisor network reflects the reduced work rather than the standalone rate. The saving comes from removing the collection phase, not from discounting the professional judgement, which is the part you are actually paying for.
Carbon Reduction Plans and government contracts
What are PPN 006 and PPN 06/21?
PPN 006 is the current Carbon Reduction Plan procurement policy note for procurements under the Procurement Act 2023 regime. PPN 06/21 remains relevant to procurements and contracts under the earlier regime; check the tender documents for the applicable policy.
A Carbon Reduction Plan needs more than building energy bills. It includes the required emissions information, a commitment to net zero, relevant reduction measures and approval. Publication and update requirements must also be met.
Read the official PPN 006 guidance and documents for scope, thresholds and the template.
How does Algi generate a Carbon Reduction Plan?
Building consumption records can support the energy part of a Carbon Reduction Plan. They do not establish all organisational emissions, required Scope 3 categories, a net-zero commitment or board approval.
Discuss your tender requirements, organisational boundary and evidence gaps before commissioning preparation. Emissions factors and methods must match the reporting period and required scope.
Confirm the final plan against the applicable procurement guidance before approval and publication. An energy analysis export is not automatically a compliant Carbon Reduction Plan.
When do I need a Carbon Reduction Plan?
Check the procurement policy and tender documents that apply to the contract. PPN 006 and legacy PPN 06/21 are not universal reporting requirements for every UK building or business.
Private customers and supply-chain partners may ask for emissions information or a Carbon Reduction Plan under their own purchasing criteria. Read those requirements rather than assuming the government template covers them.
Agree the reporting boundary, evidence and approval needed for the specific request.
Housing and Awaab's Law
What is Awaab's Law and what does it require?
Awaab's Law was introduced by the Social Housing (Regulation) Act 2023. It sets fixed statutory timeframes within which registered housing providers must investigate and address specified hazards in their properties, including damp and mould. The timeframes replace a position in which "reasonable time" was interpreted differently by every landlord and tested only in retrospect.
It is being brought in in phases. Phase 1 came into force in October 2025, covering damp and mould hazards and emergency hazards. Phase 2 begins on 30 November 2026 and extends the duties to a wider set of hazards. Each phase adds obligations rather than replacing the previous one.
The change that matters most operationally is not the clock. It is the expectation that providers can demonstrate they are proactively monitoring conditions across their stock rather than only responding once a resident has complained. A complaints-driven record shows what was reported. It does not show what the conditions in a home actually were, and it cannot show that anything was being watched between reports.
Providers therefore need two things: a way to see conditions continuously, and a record of that observation which holds up when it is examined months later by a regulator, an ombudsman or a court.
How does Algi monitor housing conditions?
Algi Sense units measure temperature, relative humidity and CO2 continuously, sampling at one-minute intervals. Each unit is battery powered and wireless, and reports through the Algi Hub installed at the property.
Sustained high relative humidity is flagged as condensation risk. The word sustained is doing real work there: humidity spikes during a shower or while cooking are normal and self-correcting, and a system that alerts on those produces noise that gets switched off within a fortnight. What matters is humidity that stays elevated after the activity has stopped, because that indicates the moisture is not clearing, which is a ventilation question rather than a behaviour one.
Humidity spikes that may indicate possible leaks are surfaced separately for investigation, on the basis that a sharp, sustained rise with no matching occupancy pattern is worth a human looking at.
All readings are timestamped and stored, whether or not they triggered anything. The data that proves conditions were normal is as important as the data that flags a problem, and it only exists if it was being recorded all along.
Does using Algi make a provider compliant with Awaab's Law?
No, and it is important to be exact about this. Algi provides continuous monitoring data and a defensible evidence trail. It does not guarantee compliance, ensure legal safety, or prevent mould.
Compliance under Awaab's Law depends on what a provider does: whether hazards are investigated within the statutory timeframes, whether residents are informed, whether works are carried out, and whether all of that is properly recorded. Those are operational duties that sit with the landlord, and no piece of software discharges them.
What monitoring provides is evidence. Evidence that conditions in a home were being observed continuously rather than checked after a complaint, evidence of what those conditions actually were on a given date, and evidence that a response followed a trigger within a documented period. That is the difference between asserting that a property was managed properly and being able to show it.
Any supplier telling a housing provider that their product delivers compliance is describing something software cannot do. The obligation is not transferable.
What is the evidence trail and how does it work?
Every sensor reading is timestamped and stored against the property and the room it came from. That continuous record is the foundation, and it exists independently of whether anything went wrong, which is what makes it evidence rather than incident reporting.
When a condition crosses a threshold and triggers an alert, the alert is logged against the same timeline. Any response is then logged against it too: who was notified, when, what was inspected, what maintenance action was raised, and when the conditions returned to normal afterwards. The result is a single chronological record running from observation through to resolution, rather than sensor data in one system and a works order in another with nothing joining them.
The full record exports as PDF or CSV for a case file, a complaint response, an ombudsman determination or a regulatory inspection. The export is per property and per period, so a single home's history can be produced without extracting anything about the rest of the stock.
The reason this is built as an export rather than a dashboard view is that the moment the record is needed is usually months or years after the events in it, and typically by someone outside the organisation. It has to stand alone.
Can the sensors detect mould growth directly?
No. Algi monitors the conditions that correlate with mould risk. It does not detect mould growth, and no environmental sensor does.
The two conditions it tracks are sustained high relative humidity, which is the primary driver of surface condensation, and inadequate ventilation. Ventilation is inferred from the CO2 decay curve: when a room is occupied, CO2 rises, and when occupancy ends the rate at which it falls back indicates the air change rate. A room that clears slowly is a room where moisture will also linger, and the CO2 record shows that whether or not anyone has reported a problem.
What that gives a housing provider is a prioritised evidence base for investigation. A home showing sustained elevated humidity and a slow air change rate is a home worth inspecting, and the data says why and since when. The inspection, the diagnosis and the remedial work remain human tasks.
Hardware
What is the Algi Hub?
The Algi Hub is a Raspberry Pi-class gateway, one per property. It is the bridge between whatever the building already has and the platform, and it is the only device that needs a network connection.
It talks to building systems over WiFi, Modbus, BACnet, Zigbee and Bluetooth Low Energy. That range is deliberate. Modbus and BACnet are what building management systems, meters and plant controllers actually speak, while Zigbee and BLE cover the wireless sensors and controls that have been added to buildings piecemeal over the last decade. A gateway that only spoke one of them would work in a demonstration and fail in a real building.
The Hub discovers wireless devices on the property network and reports what it finds, so an estate manager can see what is already installed rather than relying on records that were last accurate at handover. It feeds all of that to the platform, where it joins the bill and public data already held for the property.
It also runs control loops locally. Anything that has to respond in real time, such as an HVAC adjustment triggered by occupancy or by a sensor threshold, executes on the Hub without waiting on a round trip to the cloud, and continues to run if the site loses its internet connection.
What does Algi Sense measure?
Temperature, relative humidity, CO2 and PM2.5. Each unit is battery powered and wireless, and installs in minutes with no cabling and no commissioning visit, which is what makes it viable to deploy across a portfolio rather than a demonstration room.
CO2 is the most useful of the four and the least obvious. Its rise rate indicates occupancy, because people are the dominant indoor CO2 source, so a room's actual usage pattern can be read without a camera or a booking system. Its decay curve, the rate at which CO2 falls once occupancy ends, reveals the ventilation rate in air changes per hour. That single measurement answers a question most buildings cannot otherwise answer: whether the ventilation the design intended is the ventilation the space is getting.
The one-minute sampling interval is set by that calculation rather than by a preference for granularity. Estimating an air change rate from a decay curve needs enough points across the decay to fit it properly, and at coarser intervals a typical office decay produces too few readings to be reliable. One minute also resolves short humidity events, which is what separates a shower from a leak.
Temperature and humidity together give the condensation risk picture described in the housing section above, and PM2.5 gives the particulate reading that sits against the outdoor CAMS figure for the same location, so indoor air can be compared with the air outside rather than assessed in isolation.
What is the Bio Wall?
The Algi Bio Wall is a 4ft by 4ft wall-mounted panel containing living Spirulina culture behind a woven fabric face. It processes airborne particulates and CO2 as part of the building's air handling, and it is designed to complement HVAC rather than replace it.
In controlled testing it has shown HVAC load reductions of 25-30%* per room and approximately 10%* at property level when integrated with the building's air handling system. Patent application GB2404515.5 pending.
It is the last thing a building gets rather than the first. The software establishes what a building consumes and where, monitoring establishes what conditions in it actually are, and only then is there a baseline against which a physical intervention can be judged. Installing hardware into a building nobody has measured produces an anecdote instead of a result.
*Illustrative range based on controlled environment testing. Results vary by building type, occupancy, and HVAC configuration. These figures are design targets for Bio Wall hardware deployments only. They do not apply to the software platform.
Why is all hardware leased?
Algi offers hardware through a lease so installation and ongoing support can be scoped together. The signed agreement should specify equipment, maintenance, replacement, term and collection responsibilities.
A lease does not automatically keep equipment off your balance sheet. Accounting treatment depends on the contract and the accounting rules your organisation follows.
Confirm the commercial and accounting implications before committing.
Is there a purchase option instead of leasing?
Algi offers hardware through its leasing model. Discuss the required deployment and terms before committing.
Installation, maintenance, replacement and collection are governed by the agreement. Ask your finance adviser about the applicable accounting treatment.
Packages and pricing
What are the six Algi packages?
Essentials focuses on building records and bill analysis. Comply focuses on reporting preparation. Monitor and Housing cover separately scoped indoor monitoring deployments for commercial buildings and housing providers.
Complete brings together an agreed software, hardware and advisory scope. Enterprise is tailored to multi-site portfolios and integrations. Confirm the available outputs and delivery scope before committing.
Packages are quoted per property; Enterprise is quoted per portfolio. Start with the free public-data report and discuss which additional services fit your needs.
How does the advisor network handle accredited sign-off?
Software can help prepare records, but qualified professionals retain responsibility for their assessments. ESOS generally requires a registered Lead Assessor; EPC and DEC work requires the appropriate assessor.
Agree adviser availability, professional scope, fees, site visits and sign-off responsibilities before commissioning. Preparing records may make work easier to scope, but does not guarantee a discounted fee.
What does the typical annual compliance spend add up to?
The site uses an illustrative comparison, not a fee every property incurs. It combines GBP 7,100 for SECR, GBP 2,000-5,000 for an energy broker, GBP 2,000-4,000 for Carbon Reduction Plan preparation, and GBP 1,500-3,000 for benchmarking.
An ESOS engagement of GBP 8,000-15,000 spread over four years contributes GBP 2,000-3,750 per year. Including Carbon Reduction Plan preparation once in the comparison year gives GBP 14,600-22,850. The homepage uses a selected GBP 17,600 scenario within that range.
These are planning examples, not current quotes or guaranteed savings. Obligations generally apply to organisations, not every building separately. Costs, frequency and scope vary; Algi may still require separately commissioned professional work.
Is there a free tier?
The property brief is free. Enter a UK commercial building address to preview a report from public data. Some sections stay blurred until you create a free account, which unlocks the full report and saves it in Algi. No payment or paid subscription is required. This is the zero-data brief described at the top of this page.
The first bill analysis is also free. That is deliberate: the point at which the platform proves itself is the point at which it reads a real bill and names something specific, and putting that behind a subscription would mean asking for money before showing anything.
Paid subscriptions begin when ongoing monitoring earns its place, which is when there is more than one bill, more than one period to compare, or a compliance obligation with a date attached to it.
