Air conditioning for extensions and kitchen-diners in Sleaford
The East Midlands gets warm, dry summer spells, and loft conversions and top-floor bedrooms are where the heat builds. For a kitchen-diner in Sleaford, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
An extension in Sleaford with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Sleaford is about 17 miles from Lincoln and falls within our Lincolnshire coverage. We cover NG34 and the streets around them.

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 Sleaford 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. A survey in Sleaford 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.
