Heat load surveys and system design across Glasgow and Dunbartonshire
Every Glasgow quote starts with a room-by-room survey rather than a guess from floor area. For self-builds and extensions in Glasgow, a standalone design pack can go straight to your builder. Scottish summers are mild, so most systems here are chosen first for efficient heating, with cooling for warm spells.
Prices in Glasgow and Dunbartonshire
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. Larger homes, more zones and full drawing sets for a builder are what move a design pack towards the upper figure.

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
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. 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.
