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 Porthmadog 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.

Winter daylight and heating in Porthmadog
Porthmadog has about 7 hours 34 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 Porthmadog: questions
What size heat pump does a Porthmadog home need?
It depends on the heat loss, not the postcode. As a rough guide, a 3 bedroom semi often needs 6–9 kW, but the room-by-room survey sets the actual size for your Porthmadog home.
Do I need new radiators for a heat pump in Porthmadog?
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 Porthmadog home gives a room-by-room list.
Where would the outdoor unit go on a Porthmadog 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 Porthmadog home.
Do you cover Pwllheli as well as Porthmadog?
Yes. We arrange surveys and installation in Pwllheli, which is about 12 miles west of Porthmadog, and across Gwynedd.
