Heat load surveys and system design in Exmouth

Heat load surveys and system design in Exmouth

For self-builds and extensions in Exmouth, a standalone design pack can go straight to your builder. Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks.

No two rooms in Exmouth gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Our Devon coverage takes in Exmouth, about 37 miles from Plymouth. Postcode districts we cover here include EX8.

Prices in Exmouth

In South West England, our guide range for heat load surveys and system design is £395–£1,250 for a standalone design pack, including VAT. 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. On our South West England figures, the Design pack option (drawings and schedules for one home) is about £395–£795.

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

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. We book surveys in Exmouth at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
