What to know about replacing a gas boiler with a heat pump in Thornton-Cleveleys
The question for a Thornton-Cleveleys home is rarely whether a heat pump can work, but what needs to change to make it work well: radiator sizes, pipework, controls and where the unit goes.
Many gas-heated homes in Thornton-Cleveleys have a combi boiler in the kitchen, so the survey starts by finding the right place for a cylinder. Installers in Thornton-Cleveleys 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
- Boilers that are old, unreliable or due for replacement
- 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
- System flush and radiator upgrades where the design calls for them
- Removal of the gas boiler, flue and any loft tanks
- Commissioning, MCS certificate and grant application in England and Wales where eligible
- Free survey with heat loss calculation and cylinder siting
Semi-detached and terraced houses in Thornton-Cleveleys often have an airing cupboard that can be reused for a heat pump cylinder.
Grants and rules for heat pumps in England
Homes in Thornton-Cleveleys 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.

Replacing a gas boiler with a heat pump in Thornton-Cleveleys: questions
How long does a heat pump survey take in Thornton-Cleveleys?
A home survey in Thornton-Cleveleys usually takes one to two hours. The surveyor measures every heated room, checks windows, walls and radiators, and looks at where the outdoor unit and cylinder can go.
How soon can you survey a home in Thornton-Cleveleys?
Survey dates depend on how busy installers are in Lancashire. We offer the next available dates when you enquire and confirm them in writing.
How long does installation take in Thornton-Cleveleys?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Thornton-Cleveleys home states the expected time.
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.
Can a heat pump replace a combi boiler?
Yes, but you need room for a hot water cylinder, because heat pumps store hot water rather than heating it on demand. Most homes find a space in a cupboard, utility room, garage or under the stairs, and compact or combined indoor units help where space is tight. The survey measures the options first, so you know where everything will go before you accept the quote.
