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 Ystradgynlais 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.

How long is the heating season in Ystradgynlais?
Ystradgynlais has about 7 hours 47 minutes of daylight at midwinter and 16 hours 41 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 Ystradgynlais: questions
Where would the outdoor unit go on a Ystradgynlais 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 Ystradgynlais home.
Do you cover Pontardawe as well as Ystradgynlais?
Yes. We arrange surveys and installation in Pontardawe, which is about 5 miles south-west of Ystradgynlais, and across Powys.
How long does installation take in Ystradgynlais?
Most installations take 2–4 days on site. Jobs with several radiator changes or new pipework take longer, and your quote for a Ystradgynlais home states the expected time.
Do I need new radiators for a heat pump in Ystradgynlais?
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 Ystradgynlais home gives a room-by-room list.
