Most UK houses can run a heat pump well. The question isn't usually whether a heat pump will work in your home, but what needs to be in place for it to run efficiently. Here's how to tell.
The quick suitability checklist
- Outside space for a unit about the size of a large suitcase, with clear airflow.
- Room for a hot water cylinder, or a place one could go.
- A wet central heating system (radiators or underfloor heating).
- Reasonable insulation: loft insulation and draught-proofing at least.
- Ownership, or the owner's permission if you rent.
Heat pumps by house type
Detached houses
Usually the easiest installs: plenty of outdoor space and room for a cylinder. Larger homes need a bigger unit, typically 8 to 14 kW.
Semi-detached houses
The most common UK heat pump install. A 6 to 8 kW unit typically suits a three-bed semi, and many need only a couple of radiators upgrading.
Terraced houses
Units usually go in the rear garden or yard. Wall-mounted brackets help where space is tight, and the MCS noise assessment checks the distance to neighbours.
Bungalows
Bungalows are often well suited, with space for a unit and a cylinder. Loft insulation makes a big difference in single-storey homes.
Flats
Possible with somewhere to site the outdoor unit and the freeholder's consent. Smaller heat demand means a compact unit.
What about older or solid-wall homes?
Older homes lose more heat, so they need a carefully sized system and sometimes larger radiators. Simple steps like loft top-ups, draught-proofing and secondary glazing reduce the size (and cost) of the heat pump needed.
