Heat load surveys and system design in Launceston
Every Launceston quote starts with a room-by-room survey rather than a guess from floor area. South West summers are milder on the coast, but sheltered towns and south-facing rooms still overheat, and efficient winter heating matters just as much.
For self-builds and extensions in Launceston, a standalone design pack can go straight to your builder. Launceston sits around 40 miles from Truro, inside our Cornwall area. Postcode districts we cover here include PL15.
Prices in Launceston
Heat load surveys and system design in Launceston 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. As an example, the Design pack option (drawings and schedules for one home) would typically be £395–£795 here.

Planning and permissions
For most houses in Launceston, the outdoor unit is permitted development if it passes the MCS 020(a) noise check (37 dB(A) or less at the nearest neighbouring window) and stays within the size and number limits. We run that check on survey.
The survey
On a survey in Launceston the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows. A survey in Launceston usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes.
