Heat load surveys and system design in Cwmbran
Wet South Wales winters make a heat pump's quiet, even heating and dehumidifying mode useful well beyond summer. No two rooms in Cwmbran gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing.
Every Cwmbran quote starts with a room-by-room survey rather than a guess from floor area. Cwmbran sits around 5 miles from Newport, Gwent, inside our Gwent area. Coverage includes NP44.

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. Labour rates in South and Mid Wales keep this slightly under the national middle. The design pack price depends mainly on the number of rooms and whether full drawings and equipment schedules are needed.

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