Gas boiler to heat pump for Denton homes
A heat pump suits most Denton homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
Semi-detached and terraced houses in Denton often have an airing cupboard that can be reused for a heat pump cylinder. Installers in Denton take out the old boiler and flue and seal the wall opening as part of the job.
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.
- Combi owners who can find space for a hot water cylinder
- Homes in England and Wales eligible for the Boiler Upgrade Scheme
- Households ready to give up gas entirely and drop the standing charge
What's included
- Heat pump cylinder, outdoor unit and weather compensation controls
- 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
- Removal of the gas boiler, flue and any loft tanks
If your Denton 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 Denton 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.

Designing for Denton's winters
On the shortest day Denton gets only about 7 hours 28 minutes of daylight and the noon sun sits around 13° above the horizon. Northern winters tend to be longer, so a well-designed, efficient system matters more here because it runs for more of the year.

- Tell us about your home: postcode, property type and current heating.
- We book a survey in Denton; the surveyor measures rooms, windows and radiators and looks at cylinder space.
- The design and quote arrive in writing, including radiator changes and the outdoor unit position.
- On installation days the old system is removed and the new one fitted and filled.
- We commission the heat pump, show you the controls and register the installation.
Replacing a gas boiler with a heat pump in Denton: questions
Can you service a heat pump in Denton that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Denton, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Denton?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Denton home states the expected time.
Do I need new radiators for a heat pump in Denton?
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 Denton home gives a room-by-room list.
Should I have my gas meter removed?
If gas is used for nothing else, removing the meter ends the gas standing charge, which is about £108 a year at the October to December 2026 price cap. If you still cook on gas or have a gas fire, you will need to keep the supply. Meter removal is arranged through your gas supplier, usually once the heat pump is running; the pipe at the boiler position is capped during the installation.
Do I need to replace the cylinder I already have?
Usually, yes. Older cylinders have a small internal coil designed for water from a boiler at around 60–70°C, and they cannot take in heat quickly enough at the lower temperatures a heat pump runs at. A heat pump cylinder has a larger coil. On its own, a cylinder supplied and fitted has a guide price of £1,200–£2,200, installed and including VAT, though it is normally part of the full system price.
