Air conditioning for extensions and kitchen-diners in Grantham
For a kitchen-diner in Grantham, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. In the East Midlands, one system that cools in summer and heats efficiently in winter makes good use of the investment.
An extension in Grantham with a roof lantern or large glazed doors can overheat quickly on a sunny afternoon. Grantham lies roughly 22 miles from Lincoln, and we cover it as part of Lincolnshire. That includes the NG31 postcode district.
Prices in Grantham
Our East Midlands guide price for air conditioning for extensions and kitchen-diners is £1,395–£4,245 per space, VAT included. It is a touch below the UK middle, as trade rates in the East Midlands tend to be. Longer or hidden pipe runs, high-level brackets and electrical upgrades are the usual reasons a quote lands at the top of the range. As an example, the Large single option (one 5–7 kW unit for a large glazed space) would typically be £1,945–£2,745 here.
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.

On a survey in Grantham 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.
