Heat load surveys and system design in Dagenham
Many London homes are flats or tall terraces, where heat rises to the top floor and the bedrooms bear the brunt of a hot spell. For self-builds and extensions in Dagenham, a standalone design pack can go straight to your builder.
No two rooms in Dagenham gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. Dagenham sits around 13 miles from central London, inside our London area. That includes the RM10 postcode district.
Prices in Dagenham
Our London guide price for heat load surveys and system design is £495–£1,645 for a standalone design pack, VAT included. London is one of the dearer parts of the UK for trades, which shows in the range. The design pack price depends mainly on the number of rooms and whether full drawings and equipment schedules are needed. As an example, the Design pack option (drawings and schedules for one home) would typically be £495–£1,045 here.

Planning and permissions
For most houses in Dagenham, 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. We book surveys in Dagenham at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
