Ducted air conditioning in Wembley
Ducted systems suit Wembley loft conversions and new extensions where ceilings are being boarded anyway. London's dense streets hold heat overnight, so top-floor flats and loft rooms often stay warm long after sunset.
In an older house in Wembley, the loft and any existing bulkheads decide whether a ducted layout will work. Wembley is about 8 miles from central London and falls within our London coverage. Homes in HA0 are all within our coverage.

Guide prices show VAT at 20%. HMRC treats most fixed air conditioners and air-to-air heat pumps installed in homes as energy-saving materials, zero-rated until 31 March 2027 when we supply and fit them. If your installation qualifies, your quote shows 0% VAT and a lower price. Servicing, repairs, cleaning and controls are charged at 20%.
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
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. A survey in Wembley usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes.
