Air source heat pump installation in Gorseinon: what to expect
Homes around Gorseinon range from older terraces to newer estates, and each needs a different design. That is why we survey before we quote.
Installers working in Gorseinon plan the order of work so heating and hot water are off for as short a time as practical. Many homes in Gorseinon have a side passage or rear garden with room for an outdoor unit, and the survey checks airflow and distance from neighbouring windows.
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.
- Houses with reasonable insulation, or a plan to improve it
- Households with room for a hot water cylinder
- Owners who want one contract covering design, fitting and paperwork
What's included
- Boiler Upgrade Scheme application in England and Wales where eligible
- Free home survey and room-by-room heat loss calculation
- Outdoor unit, hot water cylinder and weather compensation controls
- Radiator and pipework changes where the design needs them
- Removal of the old boiler or heaters
For older properties in Gorseinon, the heat loss calculation looks closely at solid walls, single glazing and draughts before any unit is sized.
Grants and rules for heat pumps in Wales
Homes in Gorseinon 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.

Short winter days in Gorseinon and what they mean
On the shortest day Gorseinon gets about 7 hours 48 minutes of daylight, with the noon sun around 15° up. The heating season runs from autumn into spring, so a heat pump that is sized correctly and set up with weather compensation does most of its work in steady, cool conditions.

Air source heat pump installation in Gorseinon: questions
Do you cover Swansea as well as Gorseinon?
Yes. We arrange surveys and installation in Swansea, which is about 5 miles south-east of Gorseinon, and across West Glamorgan.
How long does installation take in Gorseinon?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Gorseinon home states the expected time.
Where would the outdoor unit go on a Gorseinon 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 Gorseinon home.
Do I need new radiators for a heat pump?
Not always; many homes keep most of their radiators and change only a few. Because a heat pump runs at a lower water temperature than a boiler, each radiator gives out less heat, so the survey checks every room against its heat loss. Rooms where the existing radiator falls short get a larger one, with a guide price of £250–£450 each, installed and including VAT.
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.
