Grants and rules for heat pumps in Wales
Homes in Llangefni 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.

These are guide prices for Gwynedd, installed and including VAT. Your final price is fixed in a written quote after the survey and depends on the heat loss of the house, the radiators that need changing and where the unit goes.

How long is the heating season in Llangefni?
Llangefni has about 7 hours 31 minutes of daylight at midwinter and 16 hours 59 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 Llangefni: questions
Do I need new radiators for a heat pump in Llangefni?
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 Llangefni home gives a room-by-room list.
Can you service a heat pump in Llangefni that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Llangefni, whoever fitted them. Tell us the make and model when you book.
Where would the outdoor unit go on a Llangefni 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 Llangefni home.
Do you cover Bangor (Gwynedd) as well as Llangefni?
Yes. We arrange surveys and installation in Bangor (Gwynedd), which is about 8 miles east of Llangefni, and across Gwynedd.
