Heat load surveys and system design in Ammanford
Every Ammanford quote starts with a room-by-room survey rather than a guess from floor area. Wet South Wales winters make a heat pump's quiet, even heating and dehumidifying mode useful well beyond summer.
For self-builds and extensions in Ammanford, a standalone design pack can go straight to your builder. Our Dyfed coverage takes in Ammanford, about 14 miles from Carmarthen. Homes in SA18 are all within our coverage.

Planning and permissions
Since 1 June 2026, Welsh permitted development rules for outdoor units closely match England's: up to 1.5 m³, two units on a detached home, one on other homes, and MCS 020a noise compliance. Listed buildings need consent, and conservation areas have extra restrictions on units facing a road.
The survey
At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote. A survey in Ammanford usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes.
