If you have a combi, there is no cylinder at the moment, so the first question is where one can go. If you have a system or regular boiler, you already have a cylinder, but it is unlikely to suit a heat pump, which needs a larger internal coil to heat water at lower temperatures. Regular boilers also have tanks in the loft that can usually be taken out, freeing space.
If your home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob. Semi-detached and terraced houses in Lancashire often have an airing cupboard that can be reused for a heat pump cylinder. Rear gardens and side returns in Lancashire usually offer a sensible spot for the outdoor unit, checked for airflow and neighbours.
Who it suits
- Combi owners who can find space for a hot water cylinder
- Households ready to give up gas entirely and drop the standing charge
- System or regular boiler homes with an existing airing cupboard
- Homes in England and Wales eligible for the Boiler Upgrade Scheme
Grants and rules for heat pumps in England
Homes in Lancashire 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.
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.

Replacing a gas boiler with a heat pump questions
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.
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.
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.
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.
