Commercial air conditioning in Rayners Lane, done properly
Air conditioning systems with an effective rated output over 12 kW must have a TM44 inspection at least every 5 years. An accredited energy assessor carries it out; we are not assessors, but we prepare systems for inspection and act on what the report finds. We are often asked to deal with commercial systems near the end of their life and older systems on refrigerants that are getting scarcer, across ceiling cassettes, wall-mounted split systems and VRF systems.
In Rayners Lane, 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 records and tell you what’s due.
The records are your 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 cost of commercial air conditioning
The diagnosis comes before the price. The main factors are:
- Which make and model is being fitted or worked on
- How far the pipework has to run, and where
- What we find on the survey or diagnosis
Our prices page shows typical ranges, but each job is priced on what it involves. Call for a fixed-price quote, and we’ll explain what it covers.
What we need to know
The more you tell us, the more accurate the quote. When you get in touch, it helps to send:
- Wide photos of the room or the existing unit
- Your installation or service records
- The fuse board and where it is in the property
VAT is set out clearly on every quote, and the rate that applies to your job is stated. Homes, businesses and different kinds of work can be treated differently for VAT, so we confirm it in writing rather than guess. For a fixed-price quote, call us on 07833 053749.

Ceiling cassettes

Questions from Rayners Lane
Can you fit air conditioning in a London flat in Rayners Lane?
In many cases, yes, once the lease and the building’s rules are checked. We look at where the outdoor unit could go, such as a balcony, flat roof or rear wall, and write it up for the freeholder or agent.
Is Rayners Lane in your area for commercial air conditioning?
We do: Rayners Lane falls inside our working area. Just give us a ring on 07833 053749 or email us with a few details.
How are commercial air conditioning installs priced?
After a site survey, with a fixed-price quote. Factors include the number of areas, the system type, access and any out-of-hours or phased work.
What does the operator have to do under the F-gas rules?
It depends on the system’s tCO2e. Systems at or above 5 tCO2e need leak checks and records with automatic leak detection at 500 tCO2e and above.
Can we book visits on a schedule?
Yes. Maintenance contracts are part of what we do, with visits at the interval your system and the manufacturer need. Each visit is written up, with F-Gas records where refrigerant work is involved.
Do I get paperwork after the visit?
Yes. It’s the record a manufacturer or the next engineer will ask to see: the date, the work, and any refrigerant added or recovered.
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.
How the visit works
Each visit follows the same order: agree the plan on site, protect the area, carry out the job, test what we have done and talk you through it. 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. The more we can see beforehand, the smoother the visit to Rayners Lane will be.
- 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.
