Making buildings cheaper to run and better to be in.

Your building is spending more than it needs to.We show you where.

Most commercial buildings overspend on energy by 20-40%. The waste is invisible until you measure it. Algi measures it.

How it works

Three steps to knowing exactly where the money goes

No login needed for the first. Upload a bill for precision. Subscribe when it earns its place.

Step 01

Enter an address

Algi pulls EPC data, floor area, heating type, building age, carbon intensity, and solar potential from public registers. No account needed, no data from you.

Step 02

Upload a bill

Our AI reads your energy bills, spots waste patterns, compares your spend against similar buildings, and writes a savings report with real figures.

Step 03

Subscribe when ready

Ongoing bill monitoring, SECR compliance reports, ESOS data preparation, grant matching, benchmarking. One subscription replaces your energy consultant.

Algi Hub connects your building systems. Algi Sense monitors conditions in real time. When the data shows it makes sense, the Bio Wall takes over air quality. Hardware is leased, never bought - it stays on our books, not yours.

Common questions

Quick answers. For the full list across every topic, see our FAQ.

Do I need to upload anything to start?
No. Enter your building address and Algi builds a property brief from public data. No account, no bill, no commitment.
What does SECR compliance actually require?
SECR requires qualifying UK companies to report energy consumption, greenhouse gas emissions, and efficiency actions in their annual Directors' Report. No third-party accreditation is needed to prepare the data - Algi generates the report from your bills.
Does Algi replace my energy consultant?
For most companies, yes. Bill analysis, savings identification, SECR reports, PPN 06/21 plans, benchmarking, and grant matching are all automated. Where a legally accredited signature is required (ESOS, EPC), our advisor network handles it at a fraction of typical rates.
How is pricing structured?
Every package is priced per property based on what you need. Book a call and we run a free brief on your building before quoting. No commitment until you see the numbers.
