ALGI explained

Questions, answered in full.

ALGI is a UK building energy intelligence platform built by OXYVIAS LIMITED. It produces a property brief for a commercial building from public records using only the address, analyses energy bills against live tariff rates, and monitors indoor conditions room by room for housing providers. Everything it reports is in kWh and pounds. This page is a detailed reference for people evaluating ALGI and for anyone researching how address-only building benchmarking, SECR reporting and continuous indoor monitoring actually work in practice.

What is ALGI?

ALGI is a UK building energy intelligence platform built by OXYVIAS LIMITED. It produces a property brief for a commercial building from public records using only the address, then sharpens that brief with your own bills. Everything it reports is in kWh and pounds.

ALGI covers two things from the same data. The first is cost: what the building spends, where it is out of line with comparable buildings, and which charges are wrong before you pay them. The second is condition: how the building actually performs to be in, not just what it costs to run.

There is a separate product line for housing providers, ALGI Sense, covered in the housing section below.

Do I need to upload my energy bills to get started?

No. ALGI starts from your address alone and returns a property brief built entirely from public records. Uploading a bill is optional and comes second, to sharpen the figures against live tariff rates.

This is the main practical difference between ALGI and tools that require a data connection before they show you anything. You do not need a meter connection, a supplier login, a letter of authority, or a bill to get a first read on a building.

The address-only brief covers EPC, comparable benchmarks, climate, grid region and air quality. Adding a bill moves the figures from indicative to measured.

Can ALGI work without my consumption data?

Yes. Without consumption data ALGI works from public records: the EPC register, comparable sector benchmarks, climate data, grid region and air quality. Those figures are indicative rather than measured, and ALGI labels them that way.

The distinction matters when you put numbers in front of a board or an auditor. An indicative figure is a modelled comparison built from public data. A measured figure comes from your own bills. ALGI always states which is which rather than blending them into one number.

How does address-only benchmarking work if you do not have my consumption data?

ALGI resolves the address to a specific building, pulls the public records attached to it, and compares it against buildings in the same sector, the same size and the same region. The result is an indicative position rather than a measured one.

The inputs are the EPC register entry for the building, comparable sector benchmarks, climate data for the location, the DNO grid region derived from the postcode, and local air quality.

The output is a starting position: where this building sits against its peer group, and what the gap to the better performers looks like. Connecting bills replaces the modelled element with your actual figures.

Is there a UK platform that does commercial EPC benchmarking and SECR reporting from just an address, without uploading bills first?

Yes. ALGI does this. You enter a UK commercial address and get an EPC-backed benchmark brief built from public records, with no bill upload, no meter connection and no install. SECR reporting is a paid-tier feature and is generated once consumption data is connected.

Those two halves are worth separating clearly, because they work differently.

The benchmark brief is genuinely bill-free. Address in, brief out, in minutes, on the free tier. It gives you EPC, comparable benchmarks, climate, grid region and air quality without you supplying anything but the address.

SECR reporting is not bill-free, and no platform can honestly claim otherwise: a SECR disclosure has to reflect your actual consumption. What ALGI removes is the consultant and the manual data collection, not the requirement to have real consumption data behind the report. In practice most organisations use the address-only brief to scope the problem, then connect bills for the reporting.

How can ALGI help reduce my building's energy costs?

ALGI reads every utility bill you connect and cross-references it against live tariff rates, flagging overcharges, anomalies and tariff mismatches before you pay them. Most buildings find at least one issue in the first ninety days.

Three things get checked on every bill: the rate you are paying against current market rates, consumption spikes the moment they appear, and reactive power charges, which are commonly applied and rarely challenged.

Alongside the billing audit, benchmarking shows the gap between your building and the best comparable performer, which is usually where the larger structural savings sit.

Can ALGI produce our SECR report?

Yes, on the Platform and Enterprise tiers. Your Streamlined Energy and Carbon Reporting obligations are met from your own consumption data, generated automatically with no consultant and no manual data collection.

The report is built from the consumption data already flowing into the platform, so it does not require a separate annual data-gathering exercise. You remain responsible for what your organisation files.

Can address-based data support SECR reporting?

Partly, and it is worth being precise about which part. Address-based public data gives you building context and an indicative baseline, which is useful for scoping and for early estimates. The SECR report itself is generated from your actual consumption data.

So the honest answer is that address data supports the work around the report rather than the report itself. It tells you which buildings in an estate are likely to matter most, and gives you a defensible starting position before any data is connected.

Connecting bills or meter data is the step that produces a report you can file.

How much does ALGI cost?

ALGI does not publish per-building prices. There is a free tier that gives you a property brief and one bill analysis at no cost, and the paid tiers are priced to the building. Book a call and ALGI runs your brief before quoting.

The reason pricing is quoted rather than listed is that the paid tiers scale with the building and the estate: how many meters, how many properties, and whether the hardware layer is included.

The free tier is genuinely free and needs no card and no install.

Is there a free version or free trial?

Yes. The Free tier gives you an instant property brief from public data plus one bill analysis, at no cost, with no meter connection and no install. It includes EPC, benchmark, climate, grid region and air quality.

What the free tier does not include is SECR compliance reporting, government grant identification, ongoing monthly bill monitoring, or benchmarking against comparable properties. Those start at the Platform tier.

What is the difference between the Platform and Enterprise plans?

Platform is the software subscription: all utilities monitored monthly, SECR reports generated automatically, government grants matched to your building, benchmarking against comparable properties, and multi-user access. Enterprise adds the leased hardware layer, real-time meter integration and a dedicated account manager.

Put another way, Platform is what you buy to understand and report on a building you already run. Enterprise is what you buy when you want the building itself instrumented, so the readings arrive continuously rather than being reconstructed from bills.

All ALGI hardware is leased rather than purchased, and is reversible.

What is the ALGI Hub and ALGI Sense?

The ALGI Hub is one device per property that brings the systems already running in your building into a single view, with no rip-out, no replacement kit and no vendor lock-in. ALGI Sense is a per-room sensor measuring temperature, humidity, CO2 and PM2.5.

Both are part of the Enterprise tier and both are leased. The Hub handles the building-level picture; Sense handles the room-level picture, logged over time so you can see trends rather than single readings.

The third device is the ALGI Bio Wall, a living wall panel that improves air quality in the spaces around it, dampens noise and supports the building's thermal performance. It is leased and fully reversible. Patent application GB2404515.5 pending.

Does ALGI work for hotels specifically?

Yes, and hotels are a core case. Hotel energy spend is driven by occupancy rather than floor area alone, so ALGI benchmarks a hotel per room as well as per square metre, against comparable properties in the same sector, size and region.

The practical value in a hotel is usually twofold: the billing audit catches tariff and reactive power problems across a large and complex meter estate, and the benchmark gives a general manager or an asset manager a defensible number to take to an owner.

How is ALGI different from just reading my smart meter or half-hourly data?

Meter data tells you what you used. ALGI tells you what it should have cost, where it is out of line with comparable buildings, and what to do next. It cross-references consumption against live tariff rates and peer benchmarks rather than presenting a graph.

Most organisations that already have half-hourly data do not have a data problem. They have an interpretation problem: nobody has time to read the graph every week, and nothing in the meter feed tells you that a rate is above market or that a reactive power charge should be challenged.

ALGI works from bills as well as meter data precisely because the money is on the bill, not in the meter.

How quickly can I see results?

The property brief comes back in minutes from the address alone, with no bill and no install. Once documents are connected, the savings report is generated in minutes as well.

The longer horizon is the billing audit, which is continuous rather than one-off. Bills are checked every month as they arrive, and most buildings find at least one issue in the first ninety days.

Who is ALGI for?

Finance and facilities leads, energy and sustainability managers, hotel general managers, and property and asset managers responsible for UK commercial buildings. Housing providers are served by a separate product line, ALGI Sense.

The common thread is responsibility for what a building costs to run and for reporting on it. ALGI is built to produce numbers that survive contact with a board, an owner or an auditor, which is why it labels every figure as indicative or measured.

Can ALGI handle a portfolio of buildings, not just one?

Yes. Properties are managed individually and across the estate, so you can see each building's position and compare across the portfolio in one view. Multi-user access for your team is included from the Platform tier.

For an estate the benchmark comparison is usually the more valuable half, because it tells you which buildings to work on first rather than treating the portfolio as one number.

What government grants or funding can ALGI help us find?

ALGI matches your building against UK schemes including IETF, SALIX zero-percent loans and UKSPF, and tells you what you qualify for. Many buildings reach net zero cost in the first year. Grant matching is a paid-tier feature.

Matching runs from the same property data as the rest of the brief, so it does not require a separate application-scoping exercise. What ALGI produces is the shortlist and the reasoning; the application itself remains yours to make.

For housing providers

Housing and ALGI Sense monitoring

For social housing asset and compliance managers, private residential portfolio managers, and housing operations leads.

What does ALGI do for housing providers?

ALGI Sense monitors the indoor environment of each home room by room and continuously: temperature, humidity, CO2 and PM2.5. Every reading is logged over time, giving you an objective, timestamped record of the conditions in each home.

The purpose is evidence. Housing providers are increasingly expected to show how they identify and manage conditions in their stock, and a continuous record is a materially stronger position than a periodic inspection note.

The same data also shows where a home is wasting energy, which is covered separately below.

How does ALGI help with Awaab's Law?

The rules on housing conditions have tightened, with damp and mould in scope and excess cold and heat following. ALGI Sense gives continuous monitoring and a logged evidence trail to support how you identify and manage those conditions. It is one part of meeting your obligations, not a guarantee of compliance.

What continuous monitoring changes is the quality of what you can show. Instead of a record of when someone visited, you have a record of how the home has actually been, hour by hour, with every reading timestamped.

To be explicit about the limit: ALGI provides monitoring and a logged record. It does not determine whether you have met a legal duty, and it is not a substitute for your own compliance process or professional advice.

Can ALGI detect damp and mould?

ALGI Sense records and flags the conditions associated with damp and mould risk, principally persistently high humidity, and does so continuously rather than at inspection points. It monitors and documents conditions. It does not prevent mould from forming and does not certify that a home is free of it.

Persistently high humidity is what lets mould take hold, so tracking it continuously lets you act on the conditions early rather than after a complaint.

The output is a record of conditions over time, not a diagnosis. Deciding what a reading means for a particular home, and what to do about it, stays with you.

Does ALGI detect leaks?

Not directly. There is no dedicated leak sensor in ALGI Sense. A sudden spike in humidity can be an early sign of water ingress, and ALGI Sense flags that change so you can investigate early.

This is an inference from the humidity reading, not a leak detection measurement. A spike can have other causes, and the value is that it prompts an investigation sooner than a resident report would.

What does ALGI Sense actually measure?

Temperature, humidity, CO2 and PM2.5, per room, continuously. Readings are logged over time so you see trends rather than single points, and every reading is timestamped.

Those four together cover the conditions residents feel first and the ones providers are increasingly accountable for: cold, heat, damp risk, ventilation and particulate air quality.

How does continuous monitoring help compared to inspections?

An inspection tells you how a home looked on the day someone visited. Continuous monitoring tells you how it has been throughout, with every reading timestamped. That turns a snapshot into a record you can show.

The practical difference shows up in two places. First, conditions that come and go, such as humidity that peaks overnight, are largely invisible to a scheduled visit. Second, when you need to demonstrate how a home has been managed over a period, a continuous log is evidence in a way that a visit note is not.

Is the monitoring data auditable?

Every reading is timestamped and logged over time, giving you a consistent and reviewable record of conditions in each home. It documents conditions. It does not certify legal compliance and is not a substitute for your own compliance process.

The distinction is between evidence and certification. ALGI produces the underlying record. What that record demonstrates, and whether it satisfies a particular duty, is a judgement for you and your advisers.

Can ALGI help us prioritise which properties need attention?

Yes. Conditions are visible home by home and across the whole portfolio in one view, so you can see which homes need attention first and track how they change over time. Prioritisation is based on the logged conditions.

Because the record is continuous, you can also see whether an intervention actually changed anything, rather than closing a case on the basis of a single follow-up visit.

Does ALGI work across a large housing portfolio?

Yes. You can see conditions home by home or across every property in one view, spot the homes needing attention first, and report on the whole portfolio from one place.

Portfolio reporting draws on the same room-level record, so an estate-wide view and a single-home view are the same data at different resolutions.

Does ALGI reduce residents' energy bills too?

Monitoring conditions is the primary job in housing and energy is secondary, but the two come from the same data. The room-level readings that flag a comfort or damp risk also show where a home is wasting energy, reported in kWh and pounds.

In practice this means a home that runs cold, or is heated hard against poor fabric, is visible as both a condition issue and a running-cost issue at the same time. Which of the two you act on first is your call.

Applied context

Regulation and industry context, applied

General and regulatory topics answered specifically as they apply to ALGI, rather than as standalone definitions.

Does ALGI help with ESOS compliance?

ALGI is not an ESOS lead assessor and does not sign off an ESOS assessment. What it provides is the continuous measurement and evidence base an assessment and its action plan draw on, in kWh and pounds, from your own data rather than a one-off survey.

The reason this matters more than it used to is the action plan. Qualifying organisations are now expected to publish what they intend to do and then report against it, which turns ESOS from a periodic audit into something you have to be able to evidence between phases.

That is a measurement problem rather than an audit problem, and it is the part ALGI addresses. Check the current qualification date and compliance deadline for the live ESOS phase with the Environment Agency, since those dates are set by the scheme rather than by us.

Do I still need a manual ESOS audit if I have continuous energy data?

Yes. Continuous data does not remove the ESOS assessment requirement, and the assessment still has to be signed off by a qualified lead assessor. What changes is the effort: the measurement and evidence the assessor needs is already collected rather than gathered manually for the audit.

The practical saving is in preparation rather than in the assessment itself. Organisations that reconstruct twelve months of consumption from paper each phase spend most of the effort before the assessor arrives.

It also changes what happens after. An action plan you have to report against needs ongoing measurement, not a snapshot taken at audit time.

Can ALGI's reporting be used for SECR without a consultant?

Yes. On the Platform and Enterprise tiers, SECR reports are generated from your own consumption data with no consultant and no manual data collection. You remain responsible for what your organisation files.

The consultant cost in SECR is usually data collection and formatting rather than judgement. When consumption data is already flowing into one place, that cost largely disappears.

How do half-hourly settlement reforms change what an energy platform is worth?

Market-wide half-hourly settlement makes granular consumption data normal rather than a competitive advantage. The value moves from having the data to interpreting it: knowing which half-hours actually cost you money and what to change.

When everyone has the same granularity, a platform that simply displays it stops being differentiated. What remains scarce is the interpretation layer: comparing your consumption against live tariff rates, against comparable buildings, and against what the building should be doing.

This is why ALGI reads bills as well as consumption. Settlement granularity tells you when you used energy; the bill tells you what you were charged for it.

What does an EPC actually tell me about running costs, and what does it not?

An EPC rates the building's fabric and services under standardised assumptions, so it describes theoretical performance rather than what you actually spend. It does not reflect your occupancy, your operating hours, your equipment load or your tariff.

This is the single most common misreading of an EPC in commercial property. Two buildings with the same rating can have very different bills, because the rating is deliberately normalised so that buildings can be compared to each other rather than to their own invoices.

ALGI uses the EPC as one input into the property brief and treats it as a fabric snapshot. The operational picture comes from benchmarks and, once connected, from your own bills.

Is ALGI an alternative to a building management system (BMS)?

No, it complements one. A BMS controls plant; ALGI interprets what the building costs, how it compares, and reports on it. On the Enterprise tier the ALGI Hub brings the systems already running in your building into a single view without a rip-out.

The two answer different questions. A BMS answers what the plant is doing right now. ALGI answers whether what the building spent was reasonable, where it sits against comparable buildings, and what to put in a report.

The Hub is explicitly designed around existing equipment, with no replacement kit and no vendor lock-in.

What is the difference between energy monitoring and energy intelligence?

Monitoring shows you consumption. Intelligence tells you whether that consumption is reasonable, what it should have cost, and what to do about it. ALGI cross-references your data against live tariff rates and comparable buildings rather than charting it.

The test is simple: if a tool produces a number that still needs an analyst to interpret before anyone can act, it is monitoring. If it produces a flagged charge, a peer comparison and a next step, it is doing the interpretation for you.

Does ALGI replace an energy consultant or an energy audit?

For routine work, largely yes: bill checking, benchmarking, grant matching and SECR reporting are generated from your own data with no consultant. For statutory assessments that require a qualified assessor, such as ESOS, no.

The useful split is between recurring analysis and statutory sign-off. Recurring analysis is what consultants have historically charged most for and what software does well. Sign-off requires an accredited person and will continue to.

How does grid carbon intensity affect my reporting?

ALGI pulls the grid intensity forecast for your DNO region as part of the property brief and uses it as regional and timing context: it indicates when supply in your region is tight, which is a cost and scheduling signal. ALGI reports outcomes in kWh and pounds.

Regional matters here. Grid intensity varies significantly between DNO regions, so a national figure tells you little about a specific building. ALGI derives the region from the postcode as part of the address-only brief.

Can I get a benchmark for a building I do not own yet?

Yes. The property brief needs only a UK address, so it works for a building you are considering acquiring or leasing just as well as one you already occupy. The figures are indicative, drawn from public records.

This is a direct consequence of the brief being bill-free: there is no data you would need the current occupier's cooperation to obtain. For acquisition or pre-lease work it gives you a defensible starting position before you have any access to the building.

What data sources does ALGI use for a property brief?

Public records: the EPC register, comparable sector benchmarks, climate data for the location, the DNO grid region derived from the postcode, and local air quality. Once you connect bills, your own consumption and tariff data is added.

ALGI states which figures are indicative from public data and which are measured from your own bills, rather than presenting a single blended number.

Why does ALGI label figures as indicative or measured?

Because the two carry different weight and should not be mixed. Indicative figures come from public records and modelled comparisons. Measured figures come from your own bills. ALGI always states which is which.

The reason is practical rather than academic. A figure you are going to put in front of a board, an owner or an auditor needs a known provenance, and a number that quietly blends a modelled estimate with an invoiced amount cannot be defended when questioned.

Does ALGI make projections about future savings?

ALGI works from actual data rather than projections. Where a figure is an estimate drawn from public records it is labelled indicative; where it comes from your own bills it is labelled measured.

This is a deliberate constraint. The alternative, a modelled savings forecast presented as a headline number, is the thing that makes energy proposals hard to trust and hard to sign off.

Do I need to install hardware to use ALGI?

No. The Free and Platform tiers are software only and need no install, no meter connection and no site visit. Hardware is the Enterprise tier, and it is optional, leased and reversible.

Most organisations start with software, build a picture of the estate, and only then decide whether instrumenting a building is worth it. Hardware is the conclusion of that process rather than the entry point.
