Independent research on UK heat pumps and the Boiler Upgrade Scheme
We don't sell heat pumps. We don't sell installer leads. We read what GOV.UK, Ofgem, MCS and DESNZ actually publish — then write it up for homeowners trying to make a £10,000+ decision.

What makes this site different from installer-owned comparison pages and lead-buying directories.
We do not own, operate, or take equity in any heat pump installer. We are not a lead-buyer. We are an editorial publisher.
Every BUS, ECO4, Home Energy Scotland and DESNZ figure cites the underlying GOV.UK or Ofgem page with the date the guidance applies from.
BUS guidance versions, the £9,000 oil/LPG uplift, EPC requirement changes — every pillar gets re-verified against primary sources at least quarterly.
We don't run quote forms, we don't sell your details to installers, and we don't operate a directory. Recommendations stand or fall on their own.
