Direct answer
Heatworthy is an independently run register of MCS-certified heat pump installers based in Greater London. It exists to make the two public checks that matter — MCS certification and company registration — easy to find in one place, alongside what each business says about itself, clearly attributed.
Independence
Direct answer
Heatworthy is not affiliated with MCS, Ofgem, DESNZ, Companies House or any government body, and no installer pays to appear or to be positioned on this register. Listings are compiled from public sources and ordered alphabetically within each borough — editorial judgement plays no part in ordering.
We check against the MCS installer search and the Companies House register because they are the two public sources that say something verifiable about an installer's certification and corporate status. See How We Verify for exactly what each check does and doesn't prove.
Funding
Direct answer
Nobody pays for a listing or for position on this register, and there are no affiliate links anywhere on the site in this version. If that changes in future, any paid placement will be clearly labelled as such and will never affect ordering — the register stays alphabetical either way.
Why there are no reviews or ratings
Direct answer
This site does not publish Google review text, star ratings or review counts for any business. Review counts can be gamed, vary hugely by how long a business has used a given platform, and say little about a specific job. We'd rather point you to your own quotes, references and the two checks that are independently verifiable.
