Free-check terms
Published 25 September 2026.
Who provides the check
FeasibilityLab is a trading name operated by an individual sole trader established and operating in England and Wales. Our correspondence address is 55 Percival Road, Enfield, EN1 1QS, England. Contact hello@feasibilitylab.co.uk or use our contact form.
These terms cover the Home Energy Optimiser free check for homes in England and Wales. It is free to use without an account or email sign-up. Using it does not order a paid service. Planning Check and any future paid assessment have separate terms.
What your result means
The check gives a readiness indication based on a public EPC record or details you enter, your answers and published rules and policy. It does not inspect the property, run a building-energy calculation, predict a future EPC rating or certify compliance. It is not an EPC and cannot be lodged.
Improvement and funding cards are options to investigate. They do not confirm suitability, grant eligibility, costs, savings or a guaranteed result. Obtain appropriate professional advice before commissioning work or relying on a result for a legal or financial decision. Using this information tool does not appoint FeasibilityLab as your professional adviser.
Records and corrections
An EPC describes an earlier assessment. We do not independently verify that it still describes the property or that your answers are correct. Corrections apply to this visit; they do not update the official EPC register. An unsuccessful lookup does not establish that no EPC exists.
An expired EPC can help you explore the property's recorded condition. It does not establish a current rating or meet a requirement for a valid certificate. A new assessment may produce a different rating. Where the register has no expiry field, we calculate expiry as ten years from lodgement. A newer certificate may supersede it.
The check cannot determine every tenancy or exemption's legal position. It does not transfer a landlord's responsibilities to a tenant.
Rules and sources
Current law, confirmed government policy awaiting legislation, and proposals are different. Future measures may change before they take effect. The sources register records the sources and individual checked dates. Those dates are not the date you ran the check.
Sources are reviewed on the published 90-day cycle. A previous result is not updated retrospectively. Check current official guidance and run the check again when circumstances change.
Availability and acceptable use
The service depends on external providers and may be interrupted, changed or withdrawn. Manual entry is available when you cannot obtain a register record. Do not overload the website, introduce malicious material, bypass access controls or use it unlawfully. Access may be restricted to protect the service and other visitors.
Content and licences
FeasibilityLab owns or licenses its original content and interface. You may use the check for its intended purpose. Third-party licences and any rights they grant continue to apply.
MHCLG certificate information other than address fields and postcodes, including the Ordnance Survey UPRN, is supplied under the Open Government Licence v3.0. Address information has separate restrictions: see the copyright and database right notice.
Responsibility and complaints
The check has the limits described above. Nothing in these terms excludes liability where exclusion would be unlawful, including fraud, fraudulent misrepresentation, or death or personal injury caused by negligence. Your mandatory statutory rights are unaffected.
Contact hello@feasibilitylab.co.uk if information appears wrong or you have a complaint. These terms are governed by the law of England and Wales, subject to the mandatory protections and court rights that apply where you live.
We will date published revisions and explain material changes. Our energy privacy notice explains the check, optional statistics and separate email permissions.
Where these claims come from
Every regulatory statement on this site traces to a named primary source and the date we last checked it. The chip says how settled each one is: in legislation means it is law today, confirmed policy means a government response has settled it but the Act or SI has not been made, and proposed means it is still an intention.
Next full review 2026-11-26, ninety days from the 28 August re-verification. The earlier 18 November date is superseded — the targeted checks on 2 and 4 September did not restart the cycle. Every claim carries its checked date, so one that has gone out of date shows as one.
