Before you book: replacing an oil or LPG boiler with a heat pump in Colwyn Bay
The question for a Colwyn Bay 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.
Bungalows and detached houses near Colwyn Bay running on LPG can move to a heat pump, with the tank collected by the supplier. Owners across Clwyd can have oil tank removal arranged alongside a heat pump installation in Colwyn Bay.
Off-gas homes have a lot to plan when switching to a heat pump: the fuel tank, older walls, rural power supplies and higher heat loss.
- Eligible homes in England and Wales within the higher grant window
- Detached houses and bungalows with garden space for the unit
- Owners tired of fuel deliveries and tank maintenance
What's included
- Removal of the oil or LPG boiler and flue
- Free survey with a detailed heat loss calculation for older construction
- Network operator notification and electrical connection
- MCS certificate and grant application in England and Wales where eligible
- Help arranging LPG tank collection with your supplier
For homes outside Colwyn Bay reached by a long drive or narrow lane, delivery of the unit and cylinder is planned in advance.
Grants and rules for heat pumps in Wales
Homes in Colwyn Bay 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 an oil or LPG boiler with a heat pump in Colwyn Bay: questions
Can you service a heat pump in Colwyn Bay that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Colwyn Bay, whoever fitted them. Tell us the make and model when you book.
How long does installation take in Colwyn Bay?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Colwyn Bay home states the expected time.
How long does a heat pump survey take in Colwyn Bay?
A home survey in Colwyn Bay 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.
Is a heat pump cheaper to run than oil?
It depends on oil prices, your home's insulation, the flow temperature and your electricity tariff, so there is no single answer. At the October to December 2026 price cap, a heat pump with a seasonal efficiency of 3.0 delivers heat for about 8.8p per kWh, and at 3.5 about 7.5p. Compare that with your oil cost per kWh of heat, allowing for your boiler's efficiency; the survey estimate gives a figure for your home.
Will I need bigger radiators in an older cottage or farmhouse?
Often in some rooms, because thick solid walls and older windows lose more heat, and heat pumps work at lower water temperatures than oil boilers. The survey checks each room. Rooms with high ceilings or large windows are common candidates for a larger radiator. Where swapping radiators is impractical, a high-temperature unit can be considered, with lower efficiency as the trade-off.
