Heat load surveys and system design across Clwyd
Every Wrexham quote starts with a room-by-room survey rather than a guess from floor area. No two rooms in Wrexham gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Mild North Wales summers mean heat pump heating is usually the headline benefit.
Prices in Clwyd
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. 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 Clwyd (drawings and schedules for one home) usually comes to about £370–£745.

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