Independent research on UK heat pumps and the Boiler Upgrade Scheme

Why Heat Pump HQ?
What makes this site different from installer-owned comparison pages and lead-buying directories.
Independent of every installer
We do not own, operate, or take equity in any heat pump installer. We are not a lead-buyer. We are an editorial publisher.
Primary-source-backed grant guidance
Every BUS, ECO4, Home Energy Scotland and DESNZ figure cites the underlying GOV.UK or Ofgem page with the date the guidance applies from.
Quarterly grant-policy refresh
BUS guidance versions, the £9,000 oil/LPG uplift, EPC requirement changes - every pillar gets re-verified against primary sources at least quarterly.
Editorial only - no lead-gen forms
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.
