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 Mumbles quote.
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.

Short winter days in Mumbles and what they mean
On the shortest day Mumbles gets about 7 hours 49 minutes of daylight, and the winter sun reaches only around 15° above the horizon at noon. Winters this far south are milder than in most of the UK, which helps a heat pump run at low flow temperatures for much of the season.
Heat pumps in Mumbles: questions
How long does installation take in Mumbles?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Mumbles home states the expected time.
Do you cover Swansea as well as Mumbles?
Yes. We arrange surveys and installation in Swansea, which is about 4 miles north-east of Mumbles, and across West Glamorgan.
What size heat pump does a Mumbles 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 Mumbles home.
Where would the outdoor unit go on a Mumbles 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 Mumbles home.
