What to know about air source heat pump installation in Dolgellau
A heat pump suits most Dolgellau homes, but the details decide how efficiently it runs. Our survey looks at insulation, radiators and hot water use room by room.
In Dolgellau, cylinder space is planned with you, often in an airing cupboard, utility room or garage. Homeowners across Gwynedd can arrange a survey in Dolgellau for a room-by-room design and a written quote before committing to anything.
We survey your home, design a heat pump system around its real heat loss, and manage the installation from the first visit to the MCS certificate.
- Households with room for a hot water cylinder
- Owners and landlords in England and Wales eligible for the Boiler Upgrade Scheme
- Houses with reasonable insulation, or a plan to improve it
What's included
- Radiator and pipework changes where the design needs them
- Removal of the old boiler or heaters
- Commissioning, handover and a walk-through of the controls
- Free home survey and room-by-room heat loss calculation
- Boiler Upgrade Scheme application in England and Wales where eligible
Many homes in Dolgellau have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
Grants and rules for heat pumps in Wales
Homes in Dolgellau 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.

How long is the heating season in Dolgellau?
Dolgellau has about 7 hours 36 minutes of daylight at midwinter and 16 hours 53 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.
How installation works in Dolgellau

- The system is commissioned, set up with weather compensation and handed over with the paperwork.
Air source heat pump installation in Dolgellau: questions
Where would the outdoor unit go on a Dolgellau 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 Dolgellau home.
What size heat pump does a Dolgellau 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 Dolgellau home.
How soon can you survey a home in Dolgellau?
Survey dates depend on how busy installers are in Gwynedd. We offer the next available dates when you enquire and confirm them in writing.
How long does an air source heat pump installation take?
A typical home installation takes 2–4 days on site. It takes longer if several radiators are being replaced, pipework is being upgraded or the cylinder is going in a new location. Your quote sets out the expected programme, including when you will be without heating and hot water. Timings are typical rather than fixed, because older homes sometimes reveal surprises once floorboards are lifted.
What grants can I get for a heat pump?
It depends on where you live. In England and Wales the Boiler Upgrade Scheme gives £7,500 towards an air-to-water heat pump, which the installer claims and deducts from your quote. In Scotland, Home Energy Scotland offers a grant of up to £7,500, with up to £1,500 more for eligible rural and island homes, but you need a written funding offer before work starts. Northern Ireland has no dedicated homeowner heat pump grant at present.
