What to think about in Trowbridge
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Leased premises
If your Trowbridge premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Conservation areas
Historic streets and listed buildings in and around Trowbridge are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Working hours
Most Trowbridge businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
FAQs for Trowbridge
How much does commercial air conditioning cost in Trowbridge?
A single wall-mounted split typically costs £1,500–£2,550 plus VAT installed in Trowbridge, and a ceiling cassette £2,250–£5,150 per unit. A small shop or office with two to four indoor units usually comes to £5,150–£17,150 plus VAT.
Do you also cover Melksham, Bath and Frome?
Yes. Alongside Trowbridge, we also cover Melksham, Bath and Frome. Each has its own page with local guide prices.
Do you handle landlord consent?
We supply the drawings, unit data sheets and method of fixing your landlord or managing agent will ask for.
Which refrigerant do new systems use?
Most new small split systems use R32, because new single splits under 3 kg in Great Britain cannot use refrigerants with a GWP of 750 or more. Larger systems vary by equipment.
Do you service systems you did not install?
Yes. We service most commercial makes and models; tell us the make and model if you know them.
