Heat load surveys and system design in Swansea
Every Swansea quote starts with a room-by-room survey rather than a guess from floor area. Wet South Wales winters make a heat pump's quiet, even heating and dehumidifying mode useful well beyond summer.
For self-builds and extensions in Swansea, a standalone design pack can go straight to your builder. Swansea is one of the main towns we cover in West Glamorgan, alongside Neath and Briton Ferry. We cover SA1 and the streets around them.
Prices in Swansea
In South and Mid Wales, our guide range for heat load surveys and system design is £365–£1,145 for a standalone design pack, including VAT. That sits a little below the UK middle, reflecting typical South and Mid Wales labour rates. 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 Swansea (drawings and schedules for one home) usually comes to about £365–£745.

Planning and permissions
Wales removed its old 3 m boundary rule on 1 June 2026, so most houses in Swansea can now have an outdoor unit under permitted development if it meets the MCS 020a noise condition. Listed buildings still need consent, and conservation areas have extra restrictions.
The survey
A survey in Swansea 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. On a survey in Swansea the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
