Heat Pumps in Cambridge
In Cambridge, heat pumps are increasingly popular as a like-for-like boiler replacement that qualifies for the £7,500 government grant. Running on electricity, a modern air source heat pump achieves a coefficient of performance (CoP) of 3.0–4.5, meaning every £1 of electricity produces £3–£4.50 of heat — compared to around £0.90 from a gas boiler.

Get a quote£7,500 Boiler Upgrade Scheme — How It Works
The BUS grant is paid directly to Green Hat, who deducts it from your installation cost. You pay the net figure — you never touch the grant money or deal with the application. To qualify, your property must have a valid EPC with no outstanding loft or cavity wall insulation recommendations. We check eligibility during the free survey and manage the full application.
How Heat Pump Installation Works
Free home survey and heat loss calculation
We visit your Cambridge property to measure room-by-room heat loss, assess insulation, check radiator sizes, and identify the right heat pump model and output. No charge, no obligation.
Detailed quote and BUS grant application
We provide a fixed-price quote showing the full cost, grant deduction, and net cost to you. We then apply for the BUS grant on your behalf before scheduling the installation.
Installation — typically 2–3 days
Our MCS-certified engineers fit the external unit, internal cylinder (if needed), controls, and connect to your existing pipework and radiators. Disruption is minimal — most Cambridge homeowners remain in the property throughout.
Commissioning and handover
We commission and test the system, set weather compensation curves for your property's heat loss profile, and walk you through the controls. Your MCS certificate is registered, activating all manufacturer warranties and grant compliance.
Local Grant Support for Cambridge Heat Pumps

Warm Homes Plan from 2027 — Register Interest Now
The Warm Homes Local Grant (replacing ECO4 from January 2027) offers up to £15,000 for eligible households in Cambridge to cover insulation, heat pumps, solar panels, and battery storage. Eligibility is income-based (household income under ~£36,000) with no benefit requirement — significantly broader than ECO4.
Solar-Powered Heating in Cambridge
Cambridge receives 1,040+ kWh/m² — well above the UK average of ~900 kWh/m². The flat Fenland landscape north and east of the city means no horizon shading for most properties. When combined with solar panels, a heat pump in Cambridge can run on free electricity for much of the year — reducing heating costs by an additional 30-50% beyond the heat pump efficiency gains alone.
Complete Home Energy System in Cambridge
A heat pump works best as part of a complete renewable energy system. Solar panels generate free electricity to power the heat pump, a battery stores surplus for overnight heating demand, and an EV charger completes the package. For Cambridge households, the combined system typically reduces total energy costs by 60-80% and eliminates fossil fuel dependency entirely.
