Heat load surveys and system design in Bexley
Every Bexley quote starts with a room-by-room survey rather than a guess from floor area. In London, heat soaks into brick and concrete during the day and comes back out at night, which is when it is hardest to sleep.
For self-builds and extensions in Bexley, a standalone design pack can go straight to your builder. Bexley is about 12 miles from central London and falls within our London coverage. We cover DA15 and the streets around them.
Prices in Bexley
Our London guide price for heat load surveys and system design is £495–£1,645 for a standalone design pack, VAT included. That is above the UK middle, mainly because labour and access cost more in London. 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. For reference, the Design pack option in Bexley (drawings and schedules for one home) usually comes to about £495–£1,045.

Planning and permissions
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
The survey
We book surveys in Bexley at a time that suits you, including early evenings by arrangement, and send the written quote afterwards. A survey in Bexley 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.
