Air conditioning for extensions and kitchen-diners across Leicestershire
An extension in Leicester with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. For a kitchen-diner in Leicester, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Summer peaks in the East Midlands make bedrooms under the roof the hardest rooms to keep comfortable.
Prices in Leicestershire
Budget around £1,395–£4,245 per space including VAT for air conditioning for extensions and kitchen-diners in and around Leicestershire. That sits a little below the UK middle, reflecting typical East Midlands labour rates. Quotes move with the length of the pipe run, where the outdoor unit can sit and how much electrical work the job needs. For reference, the Large single option in Leicestershire (one 5–7 kW unit for a large glazed space) usually comes to about £1,945–£2,745.
Single unit
One 3.5–5 kW unit for a medium extension.
Large single
One 5–7 kW unit for a large glazed space.
Twin units
Two indoor units on a multi-split for long or L-shaped spaces.
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
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. On a survey in Leicestershire 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.
