Signs you need commercial air conditioning in Lee
Ageing systems are a common reason for a call. Parts become harder to find and the system can’t keep up so replacement starts to make more sense than repair.
Customers normally contact us when they notice something like this:
- Leak check schedules that have slipped
- R410A systems getting dearer to top up
- Server rooms running too warm
If your office near Lee station has a comms or server room, it needs cooling all year, not just in summer.

Commercial air conditioning in Lee, done properly
There’s no single best commercial system. Splits for small rooms, cassettes for open-plan ceilings, ducted for a hidden finish and VRF or VRV for many zones on one system. We set out the choices and the reasons behind our recommendation. Common call-outs are for fit-outs and refurbishments that need new air conditioning and missing F-gas records for commercial systems, across wall-mounted split systems, ceiling cassettes and VRF systems.
In a London area like Lee, commercial air conditioning goes into offices, shops, restaurants and server rooms, often in shared buildings. That means planning noise, outdoor unit positions and access with the landlord or managing agent, and the work is normally planned around trading hours.
We are an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Our engineers hold the F-gas qualifications needed to work on refrigerant.

FAQs for Lee
Is air conditioning in Lee permitted development?
That depends on the building and where the outdoor unit goes. The centre of Lee is in the Lee Manor Conservation Area. 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 Lewisham council, which is normally the planning authority for Lee when it matters.
Is Lee in your area for commercial air conditioning?
Yes. Lee is one of the places we cover. Get in touch with the details and we reply the same working day.
Do you provide ongoing maintenance for businesses?
Yes. With a contract, servicing and F-gas checks happen on time, with records kept for each visit.
Whose job is it to check the system for leaks?
Whoever operates the equipment, together with the technicians who service it. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
Are you F-Gas certified?
We are an F-Gas certified company, NICEIC approved for electrical work and MCS certified for heat pumps. We are members of Checkatrade too.
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 is a legal requirement, and it also matters for the manufacturer’s warranty. We are happy to quote for the full job, supply to commissioning.
Do I need to service the system to keep the warranty?
For some brands, yes. Send us the make and model and we will tell you what the manufacturer expects, and book the service at the interval they recommend.

Managing agents and facilities teams in Lee
Landlords, letting agents and managing agents book us, not only the people who live or work in the property. Let us know who will give us access and who the records should go to, and we will keep everyone informed.
Whether it’s one property or many, you get the same standard: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
What we do, step by step
Think of the visit in three stages: look, put right and sign off. First we check the system or the space against the plan, then we do the work, and finally we test, record and explain. Most of the time goes on the middle part, which takes from a couple of days for a few cassettes to a planned programme for a whole building. For a job in Lee, tell us about parking, permits and access to the building when you get in touch.
- We survey the site and talk through how each area is used.
- We recommend a system and send a fixed-price quote.
- The programme is agreed, including any out-of-hours or phased work.
- We install the units, pipework, drainage, electrics and controls.
- Commissioning and handover follow, with the F-gas records and manufacturer paperwork.
Getting ready for the visit
- Tell us about access, such as roof hatches, high walls or locked plant areas
- Make sure we can reach the consumer unit or fuse board
- Let us know where we can park and unload

Advice
Aftercare tips

- Track when the next TM44 inspection is due
- Call about warning signs straight away

Simple control settings help. Units heating and cooling the same space at once is a common problem, and we can help set them up.
Cooling for Lee businesses
Food Standards Agency data counts about 234 restaurants, cafés and canteens, about 4 hotels, B&Bs and guest houses and about 26 schools and colleges within about 1.5 miles of central Lee. Restaurants, hotels, schools and care settings each need cooling designed for their hours and heat loads. Valuation Office Agency council tax records put about 49% of homes in Lee and the neighbourhoods around it before 1919, and about 57% of households live in flats, according to the last census (2021). 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.
Churches and halls such as Church of the Good Shepherd are often used a few hours at a time, which suits a system that heats or cools a space quickly, once consents are in place.
