Heat load surveys and system design in Clydach
For self-builds and extensions in Clydach, a standalone design pack can go straight to your builder. In South and Mid Wales, efficient heating is often as important as cooling.
No two rooms in Clydach gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Clydach lies roughly 5 miles from Swansea, and we cover it as part of West Glamorgan. That includes the SA6 postcode district.
Prices in Clydach
Guide prices around Clydach run from £365 to £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.

Planning and permissions
In Wales, outdoor units of up to 1.5 m³ that meet MCS 020a noise limits are usually permitted development on houses; listed buildings need consent, and in conservation areas a unit cannot go on a wall or roof facing a road.
The survey
A survey in Clydach 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. The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote.
