Working in Brentwood
In Brentwood, typical premises are high-street shops, offices above them, surgeries, salons and local industrial units. Basildon is about 12 km away.
We cover every Brentwood postcode, including CM14. Neighbouring towns we cover include Billericay, Hornchurch and Romford.
In Brentwood, outdoor unit positions are often the deciding factor: a rear flat roof or yard is usually straightforward, while a front elevation may need landlord or planning consent first.
Before a visit in Brentwood we ask for the make, model and number of units so the engineer arrives with the right filters, parts and access equipment.

Points to plan for in Brentwood
Conservation areas
Historic streets and listed buildings in and around Brentwood are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Leased premises
If your Brentwood 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.
Working hours
Most Brentwood businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
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).
Questions from businesses in Brentwood
How much does commercial air conditioning cost in Brentwood?
A single wall-mounted split typically costs £1,550–£2,650 plus VAT installed in Brentwood, and a ceiling cassette £2,295–£5,350 per unit. A small shop or office with two to four indoor units usually comes to £5,350–£17,795 plus VAT.
Do you also cover Billericay, Hornchurch and Romford?
Yes. Alongside Brentwood, we also cover Billericay, Hornchurch and Romford. 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.
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.
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.
