Heat load surveys and system design in Hayes
No two rooms in Hayes gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset.
For self-builds and extensions in Hayes, a standalone design pack can go straight to your builder. Hayes is about 13 miles from central London and falls within our London coverage. We cover UB3 and UB8 and the streets around them.

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.
