Air conditioning for extensions and kitchen-diners in Royton
Damp North West weather makes the dehumidifying mode of a modern split system genuinely useful for much of the year. An extension in Royton with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon.
In Royton, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Our Greater Manchester coverage takes in Royton, about 7 miles from Manchester. Coverage includes OL2.

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
A survey in Royton 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. On a survey in Royton the engineer looks at room size, glazing, the route for pipes and drains, the electrics and where the outdoor unit can sit quietly, then the written quote follows.
