Ducted air conditioning in Ruislip
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. Ducted systems suit Ruislip loft conversions and new extensions where ceilings are being boarded anyway.
In an older house in Ruislip, the loft and any existing bulkheads decide whether a ducted layout will work. Our London coverage takes in Ruislip, about 14 miles from central London. We cover HA4 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.
