Heat load surveys and system design in Becontree
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. No two rooms in Becontree gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing.
For self-builds and extensions in Becontree, a standalone design pack can go straight to your builder. Becontree sits around 11 miles from central London, inside our London area. We cover RM9 and the streets around them.
Prices in Becontree
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. On our London figures, the Design pack option (drawings and schedules for one home) is 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
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.
