How much does a heat pump cost after the grant?

Often a few thousand pounds after the £7,500 BUS grant, depending on system upgrades — compare MCS quotes.

Is a heat pump cheaper to run than gas?

Running costs vary; heat pumps are 3x+ more efficient, and electricity is pricier than gas, so sizing and insulation matter.

Heat Pump Grants (UK)

A heat pump is the UK's main low-carbon heating upgrade — and there's substantial grant support. This guide sets out what you'll pay after grants so you can budget with confidence.

Last reviewed: August 2026

Boiler Upgrade Scheme

£7,500 toward an air/ground source heat pump for any homeowner; up to £9,000 for oil/LPG homes. Installer claims it and deducts from your quote.

ECO4 (fully funded)

Lower-income households can get a heat pump at no cost as part of an ECO4 package, to Dec 2026.

What you'll still pay

Even with BUS, you may pay the difference vs a like-for-like boiler, plus any heating-system upgrades (e.g. bigger radiators). Get 2–3 MCS quotes.
