Air conditioning for extensions and kitchen-diners in Maldon
Low rainfall and long summer days in the East of England make south-facing rooms the first to overheat. For a kitchen-diner in Maldon, we place the indoor unit clear of the hob and plan the outdoor unit at the rear.
In Maldon, a side wall of a single-storey extension is usually the neatest place for the indoor unit. Maldon is about 13 miles from Southend-on-Sea and falls within our Essex coverage. Postcode districts we cover here include CM9.

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
England's rules let most houses fit an outdoor unit without a planning application, as long as the size, number and MCS 020(a) noise conditions are met. Flats, listed buildings and roof-mounted units are treated differently.
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 Maldon 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.
