Heat load surveys and system design in Neath
Humid summer spells in South Wales make dehumidifying and cooling equally welcome. Every Neath quote starts with a room-by-room survey rather than a guess from floor area.
No two rooms in Neath gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Our West Glamorgan coverage takes in Neath, about 7 miles from Swansea. We cover SA11 and the streets around them.
Prices in Neath
Budget around £365–£1,145 for a standalone design pack including VAT for heat load surveys and system design in and around Neath. It is a touch below the UK middle, as trade rates in South and Mid Wales tend to be. The design pack price depends mainly on the number of rooms and whether full drawings and equipment schedules are needed. For reference, the Design pack option in Neath (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.
