Before you book: replacing a gas boiler with a heat pump in Ely
In Ely, as anywhere in the UK, the heat pumps that perform well are the ones designed around low flow temperatures and sized from a proper heat loss calculation.
Rear gardens and side returns in Ely usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours. Many gas-heated homes in Ely have a combi boiler in the kitchen, so the survey starts by finding the right place for a cylinder.
Moving from mains gas to a heat pump means finding cylinder space, deciding what happens to the gas supply and comparing running costs on realistic assumptions.
- Households ready to give up gas entirely and drop the standing charge
- Homes in England and Wales eligible for the Boiler Upgrade Scheme
- Boilers that are old, unreliable or due for replacement
What's included
- System flush and radiator upgrades where the design calls for them
- Removal of the gas boiler, flue and any loft tanks
- Free survey with heat loss calculation and cylinder siting
- Heat pump cylinder, outdoor unit and weather compensation controls
- Capping of the gas pipe at the boiler position where you are giving up gas
Households across Cambridgeshire moving off gas can have a survey in Ely that compares running costs on realistic assumptions.
Grants and rules for heat pumps in England
In England the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027), and since 28 April 2026 a valid EPC is no longer needed. The grant is applied for by the MCS-certified installer and shown as a deduction on your Ely quote.
There is no VAT on installing a heat pump anywhere in the UK until 31 March 2027. In England most houses can have an air source heat pump under permitted development, provided the unit meets the MCS noise and siting standards; the old 1 m boundary limit was removed on 29 May 2025. We flag listed buildings, flats and sensitive conservation-area positions at survey.

Winter daylight and heating in Ely
On the shortest day Ely gets about 7 hours 40 minutes of daylight, with the noon sun around 14° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Replacing a gas boiler with a heat pump in Ely: questions
How long does installation take in Ely?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for an Ely home states the expected time.
Do I need new radiators for a heat pump in Ely?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Ely home gives a room-by-room list.
Can you service a heat pump in Ely that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Ely, whoever fitted them. Tell us the make and model when you book.
Will my hot water run out with a heat pump?
Not if the cylinder is sized properly for your household. The survey asks how many people live in the home, how many bathrooms you have and whether you prefer baths or showers, then sizes the cylinder to suit. The heat pump reheats the cylinder on a schedule, often overnight and again during the day, and an immersion heater acts as a backup.
Is there a grant to replace a gas boiler with a heat pump?
In England and Wales, the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump that replaces a gas boiler, for eligible owners of existing homes. The MCS-certified installer applies to Ofgem and deducts the grant from your quote, and Ofgem contacts you to confirm. Scotland has separate Home Energy Scotland funding, and Northern Ireland has no dedicated homeowner grant at present.
