Air conditioning for extensions and kitchen-diners in Rotherham
Yorkshire summers are mostly mild, so efficient winter heating counts for as much as cooling. For a kitchen-diner in Rotherham, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
In Rotherham, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Our South Yorkshire coverage takes in Rotherham, about 6 miles from Sheffield. Homes in S60 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
On a survey in Rotherham 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.
