Air-to-air heat pumps in Caernarfon
We size every heat pump in Caernarfon for a cold winter day, then check the cooling side is right for summer. Mild North Wales summers mean heat pump heating is usually the headline benefit.
Ask at your Caernarfon survey whether the Boiler Upgrade Scheme grant could apply to your home. Our Gwynedd coverage takes in Caernarfon, about 8 miles from Bangor, Gwynedd. Homes in LL55 are all within our coverage.
Prices in Caernarfon
In North Wales, our guide range for air-to-air heat pumps is £2,745–£10,745 for 2–5 rooms, including VAT. It is a touch below the UK middle, as trade rates in North Wales tend to be. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. As an example, the Small home option (three or four rooms heated and cooled) would typically be £4,195–£6,995 here.
Two rooms
Living room and main bedroom on one outdoor unit.
Small home
Three or four rooms heated and cooled.
Whole home
Five or more rooms, sized to replace the existing heating.
Prices are shown before any Boiler Upgrade Scheme grant. The £2,500 air-to-air grant applies only to eligible homes in England and Wales, using an MCS-certified heat pump installed by an MCS-certified installer, who applies for the grant and deducts it from the price. We confirm eligibility, and which installer applies, before you commit.
Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
Planning and permissions
Since 1 June 2026, Welsh permitted development rules for outdoor units closely match England's: up to 1.5 m³, two units on a detached home, one on other homes, and MCS 020a noise compliance. Listed buildings need consent, and conservation areas have extra restrictions on units facing a road.
Caernarfon is in the Boiler Upgrade Scheme area, so eligible homes replacing oil, gas, LPG or electric heating may be able to get £2,500 off an air-to-air heat pump, as long as no fossil-fuel boiler stays in use. An MCS-certified installer must claim it; we confirm eligibility, and which installer applies, before you commit.
The survey
At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote.
