Grants and rules for heat pumps in Wales
In Wales the Boiler Upgrade Scheme gives £7,500 towards an air source heat pump (£9,000 if it replaces oil or LPG, from 21 July 2026 to 31 March 2027; £2,500 for air-to-air). The MCS-certified installer named in your quote applies to Ofgem for you, and the grant comes off your Pwllheli quote.
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 Pwllheli and what they mean
Pwllheli has about 7 hours 35 minutes of daylight at midwinter and 16 hours 55 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.
Heat pumps in Pwllheli: questions
How long does installation take in Pwllheli?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Pwllheli home states the expected time.
Do I need new radiators for a heat pump in Pwllheli?
Often some, not all. Heat pumps run best at lower water temperatures, so rooms with small radiators may need larger ones. The survey of your Pwllheli home gives a room-by-room list.
How long does a heat pump survey take in Pwllheli?
A home survey in Pwllheli 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.
