Ducted air conditioning in Stevenage
Ducted systems suit Stevenage 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 Stevenage, the loft and any existing bulkheads decide whether a ducted layout will work. Stevenage sits around 19 miles from Watford, inside our Hertfordshire area. Coverage includes SG1.

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.
