Heat load surveys and system design in Port Talbot
Every Port Talbot 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 Port Talbot, a standalone design pack can go straight to your builder. Port Talbot is about 7 miles from Swansea and falls within our West Glamorgan coverage. Homes in SA12 are all within our coverage.
Prices in Port Talbot
Heat load surveys and system design in Port Talbot typically come in at £365–£1,145 for a standalone design pack including VAT, based on South and Mid Wales rates.

Planning and permissions
Wales removed its old 3 m boundary rule on 1 June 2026, so most houses in Port Talbot can now have an outdoor unit under permitted development if it meets the MCS 020a noise condition. Listed buildings still need consent, and conservation areas have extra restrictions.
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. We book surveys in Port Talbot at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
