Heat load surveys and system design in Helston
Every Helston quote starts with a room-by-room survey rather than a guess from floor area. Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks.
For self-builds and extensions in Helston, a standalone design pack can go straight to your builder. We cover Helston as part of Cornwall, roughly 15 miles from Truro. Coverage includes TR13.
Prices in Helston
Heat load surveys and system design in Helston typically come in at £395–£1,250 for a standalone design pack including VAT, based on South West England rates. That is close to the UK middle for this kind of work. Larger homes, more zones and full drawing sets for a builder are what move a design pack towards the upper figure. Typical Design pack work (drawings and schedules for one home) lands around £395–£795 in this area.

Planning and permissions
Since 29 May 2025, England's permitted development rules allow larger outdoor units (up to 1.5 m³) and no longer require a 1 m gap to the boundary, provided the MCS 020(a) noise check is met. Listed buildings and pitched-roof installs still need permission.
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. We book surveys in Helston at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
