Heat load surveys and system design in Deeside
In North Wales, an air-to-air system can be an efficient way to heat holiday homes and bungalows, with cooling as a bonus. For self-builds and extensions in Deeside, a standalone design pack can go straight to your builder.
No two rooms in Deeside gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Deeside is about 11 miles from Wrexham and falls within our Clwyd coverage. Homes in CH5 and CH1 are all within our coverage.
Prices in Deeside
Our North Wales guide price for heat load surveys and system design is £370–£1,195 for a standalone design pack, VAT included. Labour rates in North Wales keep this slightly under the national middle. A standalone design pack is priced on the size of the home, the number of rooms and how much drawing work your builder or architect needs. As an example, the Design pack option (drawings and schedules for one home) would typically be £370–£745 here.

Planning and permissions
Wales removed its old 3 m boundary rule on 1 June 2026, so most houses in Deeside 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
On a survey in Deeside 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. We book surveys in Deeside at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
