Before you book: replacing a gas boiler with a heat pump in Knighton
A heat pump suits most Knighton homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
If your Knighton home still cooks on gas, we talk through whether to keep the supply or switch to an induction hob. Installers in Knighton 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.
- Boilers that are old, unreliable or due for replacement
- System or regular boiler homes with an existing airing cupboard
- Households ready to give up gas entirely and drop the standing charge
What's included
- Removal of the gas boiler, flue and any loft tanks
- Free survey with heat loss calculation and cylinder siting
- Heat pump cylinder, outdoor unit and weather compensation controls
- System flush and radiator upgrades where the design calls for them
- Capping of the gas pipe at the boiler position where you are giving up gas
Many gas-heated homes in Knighton have a combi boiler in the kitchen, so the survey starts by finding the right place for a cylinder.
Grants and rules for heat pumps in Wales
Homes in Knighton 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.
There is no VAT on installing a heat pump anywhere in the UK, Wales included, until 31 March 2027. Planning rules for heat pumps in Wales are set by the Welsh Government and differ from England's, so the surveyor checks the unit position against them.

Short winter days in Knighton and what they mean
Knighton has about 7 hours 41 minutes of daylight at midwinter and 16 hours 48 minutes at midsummer. That swing matters if you pair a heat pump with solar panels: summer generation can cover much of the hot water, winter generation far less.
The steps for replacing a gas boiler with a heat pump in Knighton
- Tell us about your home: postcode, property type and current heating.
- We book a survey in Knighton; 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 Knighton: questions
How soon can you survey a home in Knighton?
Survey dates depend on how busy installers are in Powys. We offer the next available dates when you enquire and confirm them in writing.
Where would the outdoor unit go on a Knighton 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 Knighton home.
How long does installation take in Knighton?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Knighton home states the expected time.
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.
