Heat load surveys and system design in Yeovil
In the South West, a system that heats well through damp winters is often as valuable as summer cooling. No two rooms in Yeovil gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing.
For self-builds and extensions in Yeovil, a standalone design pack can go straight to your builder. Yeovil lies roughly 21 miles from Taunton, and we cover it as part of Somerset. Coverage includes BA20.

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.

Planning and permissions
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
The survey
A survey in Yeovil 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. On a survey in Yeovil 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.
