Air conditioning for extensions and kitchen-diners in Louth
In Louth, a side wall of a single-storey extension is usually the neatest place for the indoor unit. 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 Louth, we place the indoor unit clear of the hob and plan the outdoor unit at the rear. Our Lincolnshire coverage takes in Louth, about 24 miles from Lincoln. Coverage includes LN11.

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
The free survey is where the real price is set: room measurements, pipe and drain routes, electrical checks and the outdoor unit position, all written into your quote. Surveys in Louth cover heat gain, pipe routes, electrics, access and noise to the nearest neighbour, so surprises on the day are rare.
