Heat load surveys and system design in Pontardawe
No two rooms in Pontardawe gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. South Wales summers can be warm and humid, and winters damp, so a reversible system earns its keep all year.
For self-builds and extensions in Pontardawe, a standalone design pack can go straight to your builder. Pontardawe lies roughly 8 miles from Swansea, and we cover it as part of West Glamorgan. Homes in SA8 are all within our coverage.
Prices in Pontardawe
In South and Mid Wales, our guide range for heat load surveys and system design is £365–£1,145 for a standalone design pack, including VAT. It is a touch below the UK middle, as trade rates in South and Mid Wales tend to be. A standalone design pack is priced on the size of the home, the number of rooms and how much drawing work your builder or architect needs.

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
On a survey in Pontardawe the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows. A survey in Pontardawe 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.
