Heat load surveys and system design in Mold
Mild North Wales summers mean heat pump heating is usually the headline benefit. For self-builds and extensions in Mold, a standalone design pack can go straight to your builder.
Every Mold quote starts with a room-by-room survey rather than a guess from floor area. Mold sits around 10 miles from Wrexham, inside our Clwyd area. Postcode districts we cover here include CH7.
Prices in Mold
For Mold, expect roughly £370 to £1,195 for a standalone design pack, VAT included, adjusted for typical North Wales rates. 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. On our North Wales figures, the Design pack option (drawings and schedules for one home) is about £370–£745.

Planning and permissions
Since 1 June 2026, Welsh permitted development rules for outdoor units closely match England's: up to 1.5 m³, two units on a detached home, one on other homes, and MCS 020a noise compliance. Listed buildings need consent, and conservation areas have extra restrictions on units facing a road.
The survey
We book surveys in Mold 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.
