Heat load surveys and system design in Prestatyn
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 Prestatyn gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing.
For self-builds and extensions in Prestatyn, a standalone design pack can go straight to your builder. We cover Prestatyn as part of Clwyd, roughly 26 miles from Wrexham. Homes in LL19 are all within our coverage.

Planning and permissions
Wales removed its old 3 m boundary rule on 1 June 2026, so most houses in Prestatyn 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
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. On a survey in Prestatyn 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.
