Are heat pumps actually right for UK homes?
Cutting through the noise — what we tell every client before they commit to an air source install.
Heat pumps are the future of home heating — but not every home is ready for one today. As MCS-accredited installers, we fit air source heat pumps regularly across the South East, and we're honest with every client about whether it's the right move for their property.
The first thing we assess is insulation. A heat pump works by delivering heat at a lower temperature over a longer period compared to a gas boiler. If your walls, loft, and floors aren't well insulated, the system will struggle to keep up — and your running costs will be higher than they need to be.
Next is the existing heating system. Homes with underfloor heating or oversized radiators are ideal candidates. Standard single-panel radiators in an older property? You'll likely need upgrades before the heat pump can perform properly.
We also look at the outdoor space. The unit needs adequate clearance and airflow, and there are planning considerations around noise — particularly in conservation areas or terraced properties where neighbours are close.
The government's Boiler Upgrade Scheme currently offers a £7,500 grant towards air source heat pump installations, which makes a significant dent in the upfront cost. But we always tell clients: the grant shouldn't be the reason you go ahead. The system has to be right for your property first.
For new builds, heat pumps make excellent sense. The property is designed from scratch with the right insulation levels, UFH, and cylinder sizing. Retrofit is where the nuance comes in — and it's where having an installer who's genuinely experienced matters most.
Our advice? Get a proper survey before you commit. We'll tell you honestly whether a heat pump is the right choice, or whether upgrading your boiler and improving insulation would serve you better for now.
