Conservatory air conditioning in Mitcham
London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset. If your conservatory in Mitcham faces south, that is where overheating is worst.
In Mitcham, the indoor unit usually goes on the original house wall inside the conservatory. We cover Mitcham as part of London, roughly 7 miles from central London. We cover CR4 and the streets around them.

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.
