We work across Brentwood's postcode districts, including CM14. Nearby, we also cover Billericay (about 8 km), Hornchurch (about 9 km) and Romford (about 10 km). Buildings across Essex range from converted period offices to modern units with deep ceiling voids, so we measure each site rather than relying on a standard package.

What to think about in Brentwood
Downtime
We schedule the swap to keep the space usable, often over a weekend.
Working hours
Most Brentwood businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
R22
Since 1 January 2015, R22 systems cannot be maintained using virgin or recycled R22. If one leaks, the practical fix is usually replacement.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Types of premises we cover in Brentwood
- Healthcare and dental: clean, quiet cooling for surgeries, clinics, dental practices and care settings.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.
In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
Common questions from businesses in Brentwood
How much does it cost to replace air conditioning in Brentwood?
Guide prices in Brentwood run from about £1,795 to £4,795 per indoor unit, plus VAT. A typical job (replacing a 3–4 unit system, re-using sound pipework) costs £6,450–£15,650 plus VAT. We fix the price in writing after a free survey.
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.
Which postcodes do you cover in Brentwood?
All of them, including CM14. Give us your postcode when you enquire and we will confirm the visit details.
Will a new system be cheaper to run?
Usually. Modern inverter systems are considerably more efficient than equipment from 15–20 years ago, though savings depend on use.
Is it illegal to use R22 air conditioning?
No — you can keep running an R22 system, but it cannot be maintained with virgin or recycled R22, so most repairs involving the refrigerant circuit are no longer possible.
