Heat load surveys and system design in Street
Coastal breezes help, but inland South West towns and glazed rooms still see uncomfortable peaks. For self-builds and extensions in Street, a standalone design pack can go straight to your builder.
Every Street quote starts with a room-by-room survey rather than a guess from floor area. Street is about 17 miles from Taunton and falls within our Somerset coverage. That includes the BA16 postcode district.
Prices in Street
For Street, expect roughly £395 to £1,250 for a standalone design pack, VAT included, adjusted for typical 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
For most houses in Street, 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
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. 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.

Here is what is included on every job in Street:
- Pipe and drain routes
