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

How long is the heating season in Holyhead?
Holyhead has about 7 hours 30 minutes of daylight at midwinter and 17 hours 00 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 Holyhead: questions
Do you cover Llangefni as well as Holyhead?
Yes. We arrange surveys and installation in Llangefni, which is about 14 miles east of Holyhead, and across Gwynedd.
Where would the outdoor unit go on a Holyhead 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 Holyhead home.
What size heat pump does a Holyhead 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 Holyhead home.
Can you service a heat pump in Holyhead that someone else installed?
Yes. We arrange servicing and repairs for most air source heat pumps in Holyhead, whoever fitted them. Tell us the make and model when you book.
