Multi-split air conditioning in Hertford
In a house in Hertford with a usable loft, multi-split pipes can often run through it so the front stays clear. Bright summers in the East of England mean solar gain through glass is usually the biggest load to design for.
Multi-split is a good fit for Hertford flats and maisonettes where only a balcony or one rear wall is available. Our Hertfordshire coverage takes in Hertford, about 17 miles from Watford. Coverage includes SG13.

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.
