Air conditioning for extensions and kitchen-diners in Atherton
In Atherton, a side wall of a single-storey extension is usually the neatest place for the indoor unit. North West summers are cooler, so many systems here earn their keep as efficient heaters, with cooling for the warmest weeks.
An extension in Atherton with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Our Greater Manchester coverage takes in Atherton, about 11 miles from Manchester. Homes in M46 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
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.
The survey
On a survey in Atherton 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. At the survey we look at how each room is used, where the sun hits it and how the pipes can reach the outside wall, then put it all in a written quote.
