Air conditioning for flats and apartments in Trowbridge
Balcony-mounted outdoor units are often the neatest solution for flats in Trowbridge. South West summers are milder on the coast, but sheltered towns and south-facing rooms still overheat, and efficient winter heating matters just as much.
Newer blocks in Trowbridge with balconies are often the simplest flats to fit. Trowbridge is about 25 miles from Swindon and falls within our Wiltshire coverage. Homes in BA14 are all within our coverage.
Prices in Trowbridge

That is close to the UK middle for this kind of work. Concealed pipework, access equipment for high walls and any electrical work are what push prices towards the upper figure.

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
Flats need more care: get your freeholder's written consent first, and expect the planning rules for a block of flats in Trowbridge to be stricter than for a house. 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
A survey in Trowbridge 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. 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.
