Commercial air conditioning in Bentley Heath, done properly
We design, install and look after air conditioning for businesses in Bentley Heath and across Greater London. That includes offices, shops, restaurants, hotels, schools and server rooms, and each one gets a system chosen for how the space is used. The work covers wall-mounted split systems, VRF systems and ceiling cassettes, and the jobs we see most are planning ahead for the HFC phase-down and systems that need out-of-hours or phased installation.
For a business in Bentley Heath, the legal side matters too: F-gas leak checks on larger systems, and TM44 inspections where total cooling output is over 12 kW. We keep the F-gas records and flag what’s coming up.
Think of the paperwork as the system’s health record: a dated account of the work and the readings we took. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

What affects the quote in Bentley Heath
Some jobs are bigger than they look, and some smaller. What affects the quote:
- The electrical supply and whether a new circuit is needed
- What state the existing equipment is in
- Whether it’s a simple split or a larger system
The cost depends on the type of system and how many units are involved, how easy the units are to reach and what the work involves. We give you a fixed price before any work starts, so there are no surprises.
Helping us quote
There’s no need for technical detail. Just send:
- Where the property is and what kind of building it is
- The fuse board and where it is in the property
- Photos showing the indoor unit and the space around it
Getting a quote is straightforward. Send a few details and pictures, and we reply the same working day. If we need to see the property first, we book a survey at a time that works for you.
What happens on the day
We book the visit for a day and time that suit you, and we let you know if plans need to move. When we arrive, we check the job against the survey or the photos you sent. If something is different, we talk it through with you before carrying on. After that, it takes a few days for a small shop or office, longer for VRF across several floors. Before a visit in Bentley Heath, we ask where the van can stop and how we reach the outdoor unit.
- You tell us about the building and what’s needed.
- We survey the site to check heat gains, layout and access.
- The options, cost and timing are set out in a fixed-price quote.
- We install around your hours, phased where needed.

Getting ready for the visit
- Let us know if the units are on a roof, a high wall or in a locked area
- Mention any managing agent or landlord rules we need to follow
- Let us know where the consumer unit is

Keeping the system healthy
Looking after it is simple, and it makes the next visit easier:
- Plan regular servicing with a contract
- Review older R410A systems before they need major repairs
- Note the 5-yearly TM44 date for systems over 12 kW
For systems over 12 kW, keep track of the 5-yearly TM44 inspection. When it comes round, we can get the system ready and carry out the recommendations.
Good records make inspections and audits easier. For systems at or over 5 tCO2e, they’re required.
What commercial work looks like in Bentley Heath
Food Standards Agency data counts about 44 cafés, restaurants and staff canteens, about 9 schools and colleges and about 14 care homes, nurseries and hospitals within 1.5 miles or so of the middle of Bentley Heath. Many of those sites need air conditioning that’s sized for long hours and maintained on a schedule. London commercial jobs typically involve a landlord or managing agent, and plant space is often tight.
For a school like Pope Paul Catholic Primary School, air conditioning work is best done out of term.

When to call us in Bentley Heath
Many businesses call us when an older system is struggling or failing. Parts become harder to find and the system can’t keep up, and replacing it becomes the better option.
Any of these is worth a proper look:
- Older systems that can’t keep up
- Comms rooms without enough cooling
- Changes of use that need a new layout
For a church or hall like Church of King Charles and the Martyr, any outdoor unit needs the right consents first.

Bentley Heath: your questions answered
Do I need permission to put air conditioning in my flat in Bentley Heath?
In many cases, yes, once the lease and the building’s rules are checked. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Can I fit air conditioning in Bentley Heath without planning permission?
That depends on the building and where the outdoor unit goes. The half-mile around the middle of Bentley Heath holds about 11 listed buildings and structures. A system that heats as well as cools may not need an application on a house, provided it stays within the permitted development limits. Cooling-only units get no such allowance, and listed buildings and road-facing positions in conservation areas need more care. We speak to the local planning authority (for Bentley Heath, normally Hertsmere council) when it matters.
Do I get paperwork after the visit?
Yes, on every job. A new system comes with commissioning details, F-Gas records and the manufacturer’s warranty information, while repairs and services get a written note of what was found and done.
Does my building need a TM44 inspection?
Where the air conditioning is over 12 kW, an inspection is needed at least every 5 years. An accredited energy assessor carries it out, and we can prepare the system and act on the report.
Can you come out in an emergency?
Yes, day and night. When you call, tell us the make, what’s happening and any error code, and we’ll advise on what to do next.
Do you offer maintenance contracts?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule with a fixed price. Leak checks required by the F-gas rules can be built in for larger systems.
What are the F-gas responsibilities for commercial air conditioning?
For systems at or above 5 tCO2e, the operator must have leak checks carried out and keep records. Checks are at least every 12 months from 5 to under 50 tCO2e, and every 6 months from 50 to under 500 tCO2e, and we can handle both.
