Around 52 frost days a year

£7,500 grant, £9,000 for oil and LPG

A heat pump in a frosty, historic city
Two things set Cambridge apart for anyone considering a heat pump. The first is the weather: dry, but with more frosty nights than most of England. Heat pumps cope well — they're the norm in Scandinavia — but the system needs sizing for the local design temperature, and the outdoor unit needs siting so defrost meltwater drains away rather than freezing on a path.
The second is the housing. Much of the city is gault-brick Victorian terraces and villas with solid walls, suspended floors and sash windows, and a lot of it sits in one of the city's 18 conservation areas or is listed. These homes convert well with larger radiators and careful siting, usually in the rear yard or garden.
Add the very hard chalk water, and a good Cambridge design pays attention to the hot water cylinder as well as the heat pump.

Frequently asked questions
Do heat pumps work in Cambridge's cold winters?
Yes. Cambridge is frostier than most English cities, but heat pumps keep working well below freezing and are standard in much colder countries. What matters is sizing the system for the local design temperature and fitting radiators large enough to run at a low flow temperature.
How much does a heat pump cost in Cambridge?
Most homes come in at around £10,000–£13,000 before the grant, more for large Victorian villas. After the £7,500 grant, our worked examples range from about £2,600 to £8,500.
Can I have a heat pump in a conservation area or listed building?
Yes. A unit at the rear is usually permitted development even in a conservation area. Front-facing units in a conservation area need planning permission, and listed buildings need listed building consent. Applications go to Greater Cambridge Shared Planning.
Can landlords get the grant?
Yes. Private landlords qualify for the £7,500 Boiler Upgrade Scheme on the same terms as homeowners.
What happens after I send an enquiry?
It goes to a single local heat pump installer from our network, who will be in touch to talk about a survey. We don't pass it round multiple firms.
Is there free help with insulation or heating?
For low-income households, yes. The Cambridgeshire Energy Retrofit Partnership, led by Cambridge City Council, funds free upgrades through the Warm Homes: Local Grant. Action on Energy Cambridgeshire has the details.
