Heat load surveys and system design in Plymouth
For self-builds and extensions in Plymouth, a standalone design pack can go straight to your builder. Damp South West winters make the dehumidifying side of a heat pump almost as useful as its cooling.
Every Plymouth quote starts with a room-by-room survey rather than a guess from floor area. We cover Plymouth and the rest of Devon, including Exeter and Paignton. That includes the PL2 and PL4 postcode districts.
Prices in Plymouth
Our South West England guide price for heat load surveys and system design is £395–£1,250 for a standalone design pack, VAT included. That is broadly in line with national guide prices. The design pack price depends mainly on the number of rooms and whether full drawings and equipment schedules are needed. For reference, the Design pack option in Plymouth (drawings and schedules for one home) usually comes to 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
We book surveys in Plymouth 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.
