Heat load surveys and system design in Welshpool
No two rooms in Welshpool gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Humid summer spells in South Wales make dehumidifying and cooling equally welcome.
Every Welshpool quote starts with a room-by-room survey rather than a guess from floor area. Our Powys coverage takes in Welshpool, about 12 miles from Newtown. Homes in SY21 are all within our coverage.
Prices in Welshpool
Budget around £365–£1,145 for a standalone design pack including VAT for heat load surveys and system design in and around Welshpool. 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. On our South and Mid Wales figures, the Design pack option (drawings and schedules for one home) is 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
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. A survey in Welshpool 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.
