Gas boiler to heat pump for Wilmslow homes
A heat pump suits most Wilmslow homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Installers in Wilmslow take out the old boiler and flue and seal the wall opening as part of the job. Rear gardens and side returns in Wilmslow usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours.
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.
- Homes in England and Wales eligible for the Boiler Upgrade Scheme
- Combi owners who can find space for a hot water cylinder
- Households ready to give up gas entirely and drop the standing charge
What's included
- Capping of the gas pipe at the boiler position where you are giving up gas
- Commissioning, MCS certificate and grant application in England and Wales where eligible
- System flush and radiator upgrades where the design calls for them
- Free survey with heat loss calculation and cylinder siting
- Heat pump cylinder, outdoor unit and weather compensation controls
If your Wilmslow home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob.
Grants and rules for heat pumps in England
Homes in Wilmslow can use the Boiler Upgrade Scheme, which takes £7,500 off the cost of an air source heat pump when it replaces fossil-fuel or electric heating. Replacing oil or LPG heating qualifies for £9,000 for installations from 21 July 2026 to 31 March 2027, and air-to-air systems for £2,500. The MCS-certified installer named in your quote applies for the grant and deducts it from the price.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Since 29 May 2025, permitted development in England allows up to two air source heat pumps on a house, each up to 1.5 m³, with no blanket 1 m boundary rule — the installation must still meet the MCS planning standards, including the noise check. Listed buildings, flats and some conservation-area positions need extra consent, which we check at survey.

Winter daylight and heating in Wilmslow
On the shortest day Wilmslow gets about 7 hours 30 minutes of daylight, with the noon sun around 13° 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.

- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Replacing a gas boiler with a heat pump in Wilmslow: questions
How long does installation take in Wilmslow?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Wilmslow home states the expected time.
What size heat pump does a Wilmslow home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Wilmslow home.
Do you cover Alderley Edge as well as Wilmslow?
Yes. We arrange surveys and installation in Alderley Edge, which is about 2 miles south of Wilmslow, and across Cheshire.
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.
