Commercial air conditioning in Colnbrook
Businesses cannot always stop for an installation. We plan out-of-hours, weekend and phased installs, so the building keeps running. The timing is set out with your quote. If the problem is older systems that can’t keep up and workspaces that overheat on warm days, we can help.
For a business near Colnbrook, outdoor units normally have room at the back of the building.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We’ll explain how the manufacturer’s terms are likely to apply before any chargeable work goes ahead.

When to call us in Colnbrook
In schools, the work has to fit around term time. Installation can be programmed for the holidays so lessons aren’t disrupted.
It’s time to call us if you are dealing with:
- R410A systems getting dearer to top up
- Missing F-gas records for commercial systems
- Installs that must fit around trading hours
If you look after a church or hall such as Church of St Thomas, an air-to-air system that warms up quickly can suit a building used on and off, subject to the right consents.

Common questions in Colnbrook
Do you cover Colnbrook for commercial air conditioning?
We do: Colnbrook falls inside our working area. Tell us a little about the job and we’ll take it from there.
Is air conditioning in Colnbrook permitted development?
The answer turns on the property and where the outdoor unit would sit. The Colnbrook Conservation Area is close to the centre of Colnbrook. Permitted development only covers heat pumps that are not used solely for cooling, and not within the grounds of a listed building. Conservation areas add limits on outdoor units facing a road. Where necessary, we check with the planning department at Slough council, normally the authority for Colnbrook.
What accreditations do you have?
F-Gas certified, NICEIC approved and MCS certified for heat pumps, and we’re Checkatrade members. Engineers who handle refrigerant hold their own F-gas qualifications as well.
Do you install in the evenings or at weekends?
Yes. Work can be scheduled around your hours and phase it where necessary.
Do you carry out TM44 inspections?
TM44 inspections are carried out by accredited energy assessors, which we are not. We get the system ready and act on the findings.
Does my building need a TM44 inspection?
Over 12 kW, a TM44 inspection is needed at least every 5 years. The rules are set out on GOV.UK, and we can help you prepare.
Which brands do you work with?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For new systems, we recommend a brand and model to suit the job and tell you why.

What we do, step by step
The visit has three parts, a bit like a doctor’s appointment: diagnose, treat and sign off. First comes a careful look at the system or the space, then we do the work, and finally everything is tested, recorded and explained. The middle part takes longest, which takes a matter of days for a modest fit-out, with larger buildings phased floor by floor or zone by zone. If a lane or gateway near Colnbrook is tight for a van, let us know and we’ll plan for it.
- An engineer walks the building with you to understand its layout, its users and its heat sources.
- A fixed-price quote follows, covering the system type, the layout and the timing.
- Dates are set with you so trading, teaching or treatment carries on, using evenings, weekends or phases where it helps.
- We fit the units, run and test the pipework, connect the condensate and wire in the controls.
- We commission the system, record the refrigerant details and hand over the controls and documents.
Preparing for the visit
- Let us know where the consumer unit is
- Tell us about any building rules, permits or sign-in
- Find the manual or the paperwork for the system, if you have it

Why it’s worth doing now in Colnbrook
An older system on R410A can be kept running, but top-up refrigerant is getting scarcer and dearer. It’s better to replace on your terms than after a breakdown. Small faults tend to grow, so it’s worth dealing with them early.
What you pay depends on the system and the number of rooms or units, how easy the units are to reach and the parts and time the job needs. You get a fixed price before work begins, so you know where you stand.

From one of our customers
“Office air con broke down in the July heatwave. Called at 8am, engineer was here by noon and fixed within 2 hours. Brilliant emergency response. They now hold the service contract for the whole building.”
