Commercial air conditioning in Welling
Commercial air conditioning comes with F-gas duties for the operator. Leak checks and records are required for systems from 5 tCO2e upwards. We handle the checks and records and remind you when the next is due. Common call-outs are for changes of use that need a new layout and planning ahead for the HFC phase-down, on VRF systems, ceiling cassettes and ducted systems.
In Welling, as anywhere in England, larger systems need F-gas leak checks, and over 12 kW of cooling a TM44 inspection is required. We keep the F-gas records and flag what’s coming up.
For a fault on a system that may still be under warranty, send us the make, model and installation date. We will tell you how the manufacturer’s warranty is likely to apply before any chargeable work goes ahead.

FAQs for Welling
Will air conditioning in Welling need planning permission?
That depends on the building and where the outdoor unit goes. The half-mile around the middle of Welling holds about 3 listed buildings and structures. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the local planning authority (for Welling, typically Bexley council).
Is Welling in your area for commercial air conditioning?
Yes. Welling is one of the places we cover. Tell us a little about the job and we’ll take it from there.
Can we book visits on a schedule?
Yes. Tell us what you have and how it’s used, and we will suggest a schedule with a fixed price. That can include the leak checks the F-gas rules require for larger systems.
Do you work on all makes?
We install and work on the leading makes, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. Tell us the make and model and we will take it from there.
Do you offer commercial maintenance contracts?
We do. A contract keeps the system serviced and any required leak checks on schedule, with records kept for each visit.
What does the operator have to do under the F-gas rules?
Operators of systems from 5 tCO2e upwards need leak checks and 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 carry out the checks and keep the records.
Will you make a mess?
Protection goes down first: dust sheets over floors and anything close to the work. Holes and fixings are agreed with you, and we clean up afterwards before we leave.
Cooling for Welling businesses
There are about 139 cafés, restaurants and staff canteens, about 34 schools and colleges and about 73 care homes, nurseries and hospitals within 1.5 miles or so of the middle of Welling, according to the Food Standards Agency’s register. Restaurants, hotels, schools and care settings each need cooling designed for their hours and heat loads. For London businesses, plant position, noise and access are planned with the building first.
If you look after a school such as Danson Primary School, classroom, office and IT room cooling is typically installed in the holidays. Before any plant goes outside a building like St John's Church, its trustees may need planning or heritage advice, and we work with whoever gives it.

What happens on the day
Each visit runs to the same pattern: agree the plan on site, put the dust sheets down, carry out the job, test what we have done and explain it all to you. The visit itself takes as long as the site and the system need, from a short install to a phased project planned around opening hours. For a job in Welling, tell us about parking, permits and access to the building when you get in touch.
- First comes a survey, looking at the building and how it’s occupied.
- You get our recommendation and a fixed price.
- The programme is agreed, including any out-of-hours or phased work.
- The system is installed, wired and connected to its controls.
- We commission the system and hand over the F-gas records and controls.
Preparing for the visit
- Tell us about parking and loading
- Dig out any previous service or F-Gas records
- Let us know if the units are on a roof, a high wall or in a locked area

For landlords and property managers
We also work for facilities teams in offices, schools and public buildings across Greater London. Work can be phased by floor, zone or building to keep disruption down.
From a single flat to a whole estate, the approach is the same: a look at the job first, a fixed-price quote, work booked with the occupier and written records afterwards.
What commercial air conditioning cannot fix

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.”
