Heat load surveys and system design in Colchester
Bright summers in the East of England mean solar gain through glass is usually the biggest load to design for. For self-builds and extensions in Colchester, a standalone design pack can go straight to your builder.
Every Colchester quote starts with a room-by-room survey rather than a guess from floor area. Colchester is about 26 miles from Southend-on-Sea and falls within our Essex coverage. We cover CO1 and the streets around them.
Prices in Colchester
For Colchester, expect roughly £445 to £1,395 for a standalone design pack, VAT included, adjusted for typical East of England rates. That is above the UK middle, mainly because labour and access cost more in the East of England. A standalone design pack is priced on the size of the home, the number of rooms and how much drawing work your builder or architect needs. On our East of England figures, the Design pack option (drawings and schedules for one home) is about £445–£895.

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 Colchester at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. Surveys in Colchester cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
