Commercial air conditioning in Childs Hill, done properly
Air conditioning systems with an effective rated output over 12 kW must have a TM44 inspection at least every 5 years. The inspection is carried out by an accredited energy assessor; we are not assessors, but we prepare systems for inspection and act on what the report finds. The work covers wall-mounted split systems, ceiling cassettes and multi-split systems, and people most often call us about TM44 recommendations that need acting on and older systems on refrigerants that are getting scarcer.
For a business in Childs Hill, 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.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. File them with the system’s paperwork, ready for the next service or a warranty query.

What commercial work looks like in Childs Hill
Food Standards Agency records list about 303 cafés, restaurants and staff canteens, about 17 hotels, B&Bs and guest houses and about 60 schools and colleges within roughly a mile and a half of the centre of Childs Hill. Restaurants, hotels, schools and care settings each need cooling designed for their hours and heat loads. The Valuation Office Agency’s council tax figures put about 45% of homes in the Childs Hill area before 1919, and about 66% of households live in flats, according to the 2021 Census. Where shops and offices sit below or beside homes, outdoor plant position and noise need extra care. London commercial jobs typically involve a landlord or managing agent, and plant space is often tight.
For a church or hall like All Saints, any outdoor unit needs the right consents first.

Keeping the system healthy
A little care keeps the system in better shape. We recommend:
- Budget for replacing ageing plant
- Avoid units heating and cooling the same space
- Report noises, leaks and faults early
Make a note of when a TM44 inspection will be due if the system is over 12 kW. We can prepare the system and act on the report.
Simple control settings help. Systems fighting each other, or set to extremes, waste effort, and we can help set them up.

The process
Protection comes first: sheets over the floor and any furniture nearby, and we ask before moving anything. Then the electrics are made safe and the work begins. It takes as long as the site and the system need, from a short install to a phased project planned around opening hours, and we tidy up before we leave. Pictures of the space and the outside wall help us plan the work in Childs Hill.
- First comes a survey, looking at the building and how it’s occupied.
- You get our recommendation and a fixed price.
- We agree the timing, with evening, weekend or phased work as needed.
- We install the units, pipework, drainage, electrics and controls.
- We commission the system and hand over the F-gas records and controls.
Getting ready for the visit
- Keep pets and children away from the work area
- Clear access to the fuse board
- Give us access to the outside wall, roof or yard where the outdoor unit sits

Some jobs can be priced from pictures, while others need a survey. Bigger systems, commercial sites and awkward pipe routes are normally surveyed on site. Either way, you get a fixed price before any work is booked.

Owner checks or an engineer?
Write down what you notice: error codes, noises, drips, smells or a drop in performance. It helps us diagnose quickly, and a photo or a short video of the display is even better.
On air conditioning, the filters in the indoor unit are usually the one part owners can clean where the manufacturer’s manual explains how. They come out, get a gentle clean and go back only when they’re dry. For a heat pump, the main owner jobs are a clear outdoor unit and sensible control settings.
Questions from Childs Hill
Will air conditioning in Childs Hill need planning permission?
It depends on the property. Central Childs Hill is a short walk from the Redington Frognall Conservation Area. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and isn’t used only for cooling. Listed buildings still need consent, and in a conservation area a road-facing wall or roof is not allowed under those rules. If there’s any doubt, we ask the planning department at Barnet council, typically the authority for Childs Hill.
Can you do commercial air conditioning in Childs Hill?
Yes. Childs Hill is one of the places we cover. Tell us a little about the job and we’ll take it from there.
Can I do any of the installation myself?
The refrigerant side has to be done by a qualified engineer working for an F-Gas certified company. That’s the law, not just our preference, and it also matters for the manufacturer’s warranty. We can quote for the whole job, from supply to commissioning.
How does the warranty work?
The manufacturer provides it, on its own terms. Some brands make regular servicing a condition, so keep your service records.
How much time does a commercial air con install need?
As a guide, it takes a matter of days for a modest fit-out, with larger buildings phased floor by floor or zone by zone. Phased or out-of-hours work may extend it but keeps the business running.
Do you offer commercial maintenance contracts?
Yes, maintenance contracts cover servicing, F-gas leak checks and records. We agree the schedule and cost up front.
Do you provide F-Gas records?
Yes, on every job. New installations come with commissioning details, F-Gas records and warranty information, and repairs and services get a record of the work.
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.”
