Heat load surveys and system design in Hawarden
In North Wales, an air-to-air system can be an efficient way to heat holiday homes and bungalows, with cooling as a bonus. No two rooms in Hawarden gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing.
Every Hawarden quote starts with a room-by-room survey rather than a guess from floor area. We cover Hawarden as part of Clwyd, roughly 10 miles from Wrexham. Homes in CH5 are all within our coverage.
Prices in Hawarden
In North Wales, our guide range for heat load surveys and system design is £370–£1,195 for a standalone design pack, including VAT. It is a touch below the UK middle, as trade rates in North 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 North Wales figures, the Design pack option (drawings and schedules for one home) is about £370–£745.

Planning and permissions
Wales removed its old 3 m boundary rule on 1 June 2026, so most houses in Hawarden 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
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. On a survey in Hawarden 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.
