Ducted air conditioning in Hatfield
In an older house in Hatfield, the loft and any existing bulkheads decide whether a ducted layout will work. Long sunny spells in the East of England put conservatories and top-floor rooms under real pressure.
Ducted systems suit Hatfield loft conversions and new extensions where ceilings are being boarded anyway. We cover Hatfield as part of Hertfordshire, roughly 11 miles from Watford. Coverage includes AL10.

Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure. As an example, the Zoned option (motorised dampers or two units for separate floors or room groups) would typically be £8,345–£12,245 here.

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
In England, most houses can have an outdoor unit under permitted development if it is no larger than 1.5 m³, meets the MCS 020(a) noise limit of 37 dB(A) at the nearest neighbour's window, and there are no more than two on a detached house or one on other houses. Listed buildings need consent.
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. 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.
