Heat load surveys and system design in Wimbledon
The urban heat island effect means London bedrooms can stay uncomfortably warm on summer nights. For self-builds and extensions in Wimbledon, a standalone design pack can go straight to your builder.
No two rooms in Wimbledon gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. We cover Wimbledon as part of London, roughly 6 miles from central London. Coverage includes SW19.
Prices in Wimbledon
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. Larger homes, more zones and full drawing sets for a builder are what move a design pack towards the upper figure. For reference, the Design pack option in Wimbledon (drawings and schedules for one home) usually comes to about £495–£1,045.

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
Surveys in Wimbledon cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare. On a survey in Wimbledon 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.
