Ducted air conditioning in Witham
Ducted systems suit Witham loft conversions and new extensions where ceilings are being boarded anyway. Low rainfall and long summer days in the East of England make south-facing rooms the first to overheat.
In an older house in Witham, the loft and any existing bulkheads decide whether a ducted layout will work. We cover Witham as part of Essex, roughly 18 miles from Southend-on-Sea. Postcode districts we cover here include CM8.

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
On a survey in Witham 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. We book surveys in Witham at a time that suits you, including early evenings by arrangement, and send the written quote afterwards.
