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.

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.

Most UK heat pump questions trace back to the grant. Our BUS 2026 explainer is the right first read.
