Heat load surveys and system design in Tonypandy
South Wales summers can be warm and humid, and winters damp, so a reversible system earns its keep all year. Every Tonypandy quote starts with a room-by-room survey rather than a guess from floor area.
No two rooms in Tonypandy gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Our Mid Glamorgan coverage takes in Tonypandy, about 10 miles from Bridgend. We cover CF40 and the streets around them.
Prices in Tonypandy
Our South and Mid Wales guide price for heat load surveys and system design is £365–£1,145 for a standalone design pack, VAT included. It is a touch below the UK middle, as trade rates in South and Mid Wales tend to be. Larger homes, more zones and full drawing sets for a builder are what move a design pack towards the upper figure. For reference, the Design pack option in Tonypandy (drawings and schedules for one home) usually comes to about £365–£745.

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
Surveys in Tonypandy cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. 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.
