Heat load surveys and system design in Bow
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 Bow gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing.

Prices in Bow
For Bow, expect roughly £495 to £1,645 for a standalone design pack, VAT included, adjusted for typical London rates. London is one of the dearer parts of the UK for trades, which shows in the range. Larger homes, more zones and full drawing sets for a builder are what move a design pack towards the upper figure. As an example, the Design pack option (drawings and schedules for one home) would typically be £495–£1,045 here.

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
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. On a survey in Bow the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
