Heat Pumps in Ely

In Ely, 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.

£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.

No grant paperwork for you to complete
EPC eligibility checked at free survey
Grant deducted from invoice — instant benefit
Available until at least 2028
0% VAT on heat pump installation
ECO4 also available for qualifying properties

How Heat Pump Installation Works

1

Free home survey and heat loss calculation

We visit your Ely 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.

2

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.

3

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 Ely homeowners remain in the property throughout.

4

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.

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 Ely 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 Ely

Ely sits on the flat Fenland with zero horizon shading — one of the highest-yielding solar locations in England. The Soham Solar Farm (12 MW, 3 miles south) demonstrates the region's exceptional generation potential. When combined with solar panels, a heat pump in Ely 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 Ely

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 Ely households, the combined system typically reduces total energy costs by 60-80% and eliminates fossil fuel dependency entirely.
