Check EligibilityFind a Heat Pump Installer Near You
A heat pump installer sizes, fits and commissions air-source or ground-source systems, usually alongside larger radiators or underfloor heating. MCS certification is the deciding credential: it is the precondition for the Boiler Upgrade Scheme grant and for most manufacturer warranties, and it cannot be applied retrospectively to an installation already done by an uncertified fitter.

Quick answer
What does a heat pump installer do, and what grant can you claim?
A heat pump installer sizes, fits and commissions air-source or ground-source systems, usually alongside larger radiators or underfloor heating. Installed cost typically runs £6,000–£14,000. The Boiler Upgrade Scheme pays toward an air-source unit in England and Wales, but only where the installer is MCS-certified — and the installer applies for the grant, so you never handle the money yourself.
Heat pump installer vs gas engineer vs plumber — for a heating replacement
| Job | Heat pump installer | Gas engineer | Plumber |
|---|---|---|---|
| Air-source heat pump install | ✅ Required for grant | ⚠️ Only if MCS | ❌ Not enough |
| Claim the Boiler Upgrade Scheme | ✅ MCS only | ❌ Unless MCS | ❌ No |
| Replace a gas boiler like-for-like | ⚠️ If Gas Safe | ✅ Recommended | ❌ Illegal |
| Upsize radiators for low flow temp | ✅ Routine | ✅ Yes | ✅ Yes |
| Room-by-room heat-loss survey | ✅ Expected | ⚠️ Sometimes | ❌ Rare |
Any installer quoting a heat pump without a room-by-room heat-loss calculation is guessing. Ask to see it before signing — an oversized unit short-cycles, runs expensively and is the most common cause of regret with this technology.
