Commercial air conditioning in Lessness Heath, Greater London
For commercial air conditioning in Lessness Heath, one call is all it takes: diagnosis, fixed price, work and sign-off. F-Gas certified, NICEIC approved and Checkatrade members.
- Comms rooms without enough cooling
- Commercial systems near the end of their life
- New tenancies needing cooling and heating
Before you call an engineer
Leave the units and pipework where they are. Moving a unit involves the refrigerant circuit, so it needs an F-Gas qualified engineer, and the electrical side needs a competent person. Ask us to quote for a move instead.
On air conditioning, the filters in the indoor unit are typically the one part owners can clean, if the manual says so. 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.
About our commercial air conditioning in Lessness Heath
Server rooms and comms rooms need cooling that keeps going. We look at the heat load and how the room is used, and can discuss backup units so one failure doesn’t take everything down. The work covers ducted systems, VRF systems and multi-split systems, and the jobs we see most are older systems on refrigerants that are getting scarcer and workspaces that overheat on warm days.
In Lessness Heath, 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.
Each manufacturer sets its own warranty period. Daikin, for example, gives a standard 2 years on split air conditioning, with longer extensions only on its air-to-water heat pumps. Whatever the brand, the manufacturer’s terms are explained on your quote.

What we do, step by step
On the day, we arrive at the time agreed with you and run through the plan before anything else. Dust sheets go down over floors and anything close to the work, and the electrics are made safe before any panel comes off.

- 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.
- The system is installed, wired and connected to its controls.
- Commissioning and handover follow, with the F-gas records and manufacturer paperwork.
Getting ready for the visit

Leave it or put it right?
An older system on R410A can be kept running, but top-up refrigerant is getting scarcer and dearer. Planning a replacement on your own timetable beats replacing it after a major failure. Getting the work done in Lessness Heath before summer avoids the busiest weeks.

When to call us in Lessness Heath

- Comms rooms without enough cooling
- New tenancies needing cooling and heating
- Work raised by a TM44 inspection

Lessness Heath: your questions answered
Can I fit air conditioning in Lessness Heath without planning permission?
It comes down to the building and the spot chosen for the outdoor unit. There’s a conservation area, the Erith Road Conservation Area, close to central Lessness Heath. Put simply: reversible systems on houses can be permitted development, cooling-only ones can’t, 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 Lessness Heath, typically Bexley council).
Can you do commercial air conditioning in Lessness Heath?
Yes. We work across London and the South East from our base in East Grinstead, and Lessness Heath is part of that. Just ring us on 07833 053749 with a few details.
Do you protect the property while you work?
We put dust sheets over floors and furniture near the work first, and the area is kept tidy throughout. Before we leave, we clear up and run through the work with you.
Can you work around our opening hours?
Yes, timing is agreed to suit you. Shops, offices, restaurants and schools all have different needs and the plan reflects it.
How much does commercial air conditioning cost?
Every commercial job is priced after a site survey. The cost depends on the size of the space, the system and how the work is phased, and you get a fixed-price quote before work starts.
How often is a TM44 inspection needed?
At over 12 kW, inspections are due at least every 5 years. The inspection is done by an accredited assessor, and we do the follow-up work.
Do you offer emergency call-outs?
Yes. If something urgent happens, like water coming from a unit or a critical room overheating, call our 24/7 line and we’ll tell you what to do first.
