Heat load surveys and system design in Mitcham

No two rooms in Mitcham gain or lose heat in quite the same way, which is exactly why rooms are measured before sizing. 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.

For self-builds and extensions in Mitcham, a standalone design pack can go straight to your builder. Mitcham sits around 7 miles from central London, inside our London area. That includes the CR4 postcode district.

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.
