How it works

Three steps to knowing exactly where the money goes

Preview your building report first. Create a free account to read it in full. Upload a bill for a more precise analysis.

Step 01

Enter an address

Algi uses public records to build an initial picture of your building. Preview the report, then create a free account to unlock the blurred sections and save it. No bills or payment needed to start.

Step 02

Upload a bill

Upload your energy bills to review recorded costs, consumption and possible billing issues. Each finding explains its evidence and what still needs checking.

Step 03

Subscribe when ready

Build a dated record of your building and uploaded bills. Add evidence over time, then involve a qualified adviser where a technical assessment or sign-off is needed.

Every number is traceable - to public data or to your own bills.

When you are ready, the building can look after itself.

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 bills are needed to start. Enter your building address to preview a report from public data. Some sections stay blurred until you create a free account in Algi. The full report is free, with no payment required.
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?
Algi helps you organise evidence and investigate building costs. It does not replace a technical survey or legally required accredited assessor. Use the report to prepare a more informed conversation with your adviser.
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.
