Heat load surveys and system design in Rhyl
Every Rhyl quote starts with a room-by-room survey rather than a guess from floor area. 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 Rhyl, a standalone design pack can go straight to your builder. We cover Rhyl as part of Clwyd, roughly 28 miles from Wrexham. That includes the LL18 postcode district.
Prices in Rhyl
For Rhyl, expect roughly £370 to £1,195 for a standalone design pack, VAT included, adjusted for typical North Wales rates. It is a touch below the UK middle, as trade rates in North Wales tend to be. The design pack price depends mainly on the number of rooms and whether full drawings and equipment schedules are needed. 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 Rhyl 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. A survey in Rhyl 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.
