Heat load surveys and system design in Largs
For self-builds and extensions in Largs, a standalone design pack can go straight to your builder. Mild Scottish summers mean cooling matters most in conservatories, lofts and rooms with large windows.
Every Largs quote starts with a room-by-room survey rather than a guess from floor area. Largs is about 19 miles from Kilmarnock and falls within our Ayrshire coverage. Coverage includes KA30.
Prices in Largs
Our Central and Southern Scotland guide price for heat load surveys and system design is £365–£1,145 for a standalone design pack, VAT included. It is a touch below the UK middle, as trade rates in Central and Southern Scotland tend to be. 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. For reference, the Design pack option in Largs (drawings and schedules for one home) usually comes to about £365–£745.

Planning and permissions
Scotland has its own permitted development rules for heat pumps and outdoor units, with stricter treatment of listed buildings and conservation areas. We check the current position for your property with you and, if needed, with the council.
The survey
We book surveys in Largs at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. 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.
