Before you book: replacing a gas boiler with a heat pump in Bangor (Gwynedd)
Most homes can run on a heat pump if the system is designed properly, and Bangor (Gwynedd) is no different. The key is matching the heat pump and radiators to the home's heat loss.
If your Bangor (Gwynedd) home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob. Many gas-heated homes in Bangor (Gwynedd) 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
- System or regular boiler homes with an existing airing cupboard
- Homes in England and Wales eligible for the Boiler Upgrade Scheme
What's included
- Capping of the gas pipe at the boiler position where you are giving up gas
- Heat pump cylinder, outdoor unit and weather compensation controls
- Free survey with heat loss calculation and cylinder siting
- Removal of the gas boiler, flue and any loft tanks
- Commissioning, MCS certificate and grant application in England and Wales where eligible
Semi-detached and terraced houses in Bangor (Gwynedd) often have an airing cupboard that can be reused for a heat pump cylinder.
Grants and rules for heat pumps in Wales
Homes in Bangor (Gwynedd) can use the Boiler Upgrade Scheme, which applies in Wales as well as England: £7,500 towards an air source heat pump, or £9,000 when it replaces oil or LPG heating for installations from 21 July 2026 to 31 March 2027. The MCS-certified installer named in your quote applies and deducts the grant.
Installing heat pumps is zero-rated for VAT across the UK until 31 March 2027. Wales has its own permitted development rules for air source heat pumps, so we check what applies to your property, including listed building and conservation-area constraints, at the survey.

Replacing a gas boiler with a heat pump in Bangor (Gwynedd): questions
Where would the outdoor unit go on a Bangor (Gwynedd) house?
Usually at the side or rear, on a level base with space around it for airflow and servicing, away from bedroom windows where possible. The surveyor checks positions at your Bangor (Gwynedd) home.
How soon can you survey a home in Bangor (Gwynedd)?
Survey dates depend on how busy installers are in Gwynedd. We offer the next available dates when you enquire and confirm them in writing.
Can you service a heat pump in Bangor (Gwynedd) that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Bangor (Gwynedd), whoever fitted them. Tell us the make and model when you book.
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.
What if my gas boiler is fairly new?
A newer boiler can still be replaced, but the timing is worth weighing. Some owners switch when the boiler needs a major repair; others prefer to plan the change for a convenient time. Across the UK, heat pump installation is zero-rated for VAT until 31 March 2027. A hybrid system, which keeps the boiler alongside a heat pump, is another option, though it is not eligible for the Boiler Upgrade Scheme in England and Wales.
