Air conditioning for flats and apartments in Hatfield
Balcony-mounted outdoor units are often the neatest solution for flats in Hatfield. Bright summers in the East of England mean solar gain through glass is usually the biggest load to design for.
In Hatfield apartment blocks, the freeholder's consent is usually the first thing to sort out. Hatfield sits around 11 miles from Watford, inside our Hertfordshire area. Postcode districts we cover here include AL10.

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%.
Consent and planning for flats
Leaseholders in Hatfield usually need the freeholder's consent for anything fixed outside, and blocks of flats often need planning permission for outdoor units. In England, permitted development allows one outdoor unit of up to 0.6 m³ on a block of flats; anything more needs planning permission.
The survey
On a survey in Hatfield 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. A survey in Hatfield usually takes one to two hours. We measure the rooms, check the walls and the consumer unit, agree the outdoor unit position with you and photograph the pipe routes.
