Your questions about commercial air conditioning in Wonersh
Is Wonersh in your area for commercial air conditioning?
Yes, Wonersh is within the area we cover. Just ring us on 07833 053749 or use the quote form with a few details.
Is planning permission needed for air conditioning in Wonersh?
There’s no single answer: the building and the outdoor unit position decide it. The Wonersh Conservation Area is close to the centre of Wonersh. Since 2025, an air-to-air heat pump on a house can count as permitted development if it meets the conditions and is not 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 Waverley council, which is normally the planning authority for Wonersh.
Why does F-Gas certification matter?
F-Gas certification shows a company is approved to work on equipment containing fluorinated gases, such as the refrigerant in air conditioning and heat pumps. That isn’t optional: it’s required by law, and we hold it.
Can you look after our air conditioning after it’s installed?
We do, with contracts covering servicing, leak checks and the paperwork. We agree the schedule and cost up front.
Which manufacturers do you install and repair?
The main ones, including Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries and Hitachi. For a new system, we suggest the make and model that suit the property and explain why.
When is a TM44 inspection required?
If the air conditioning has an effective rated output over 12 kW, an inspection is required at least every 5 years. The rules are set out on GOV.UK, and we can help you prepare.
How much time does a commercial air con install need?
The work takes anything from a day or two for a small office to several weeks of phased work on a large building. We confirm the timing after the survey, so phone us on 07833 053749 or fill in the contact form to arrange one.
About our commercial air conditioning in Wonersh
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’re not assessors, but we prepare systems for inspection and act on what the report finds. We’re often asked to deal with offices that get too hot in summer and planning ahead for the HFC phase-down, across ceiling cassettes, VRF systems and multi-split systems.
In a village like Wonersh, commercial air conditioning is typically for a pub, a shop, a surgery, a village hall or a rural business. Older buildings may be listed, so planning comes first.
Any work on the refrigerant circuit is recorded: what was done, the refrigerant type and any amount added or recovered. Keep the records with the manual and the warranty documents, as a manufacturer or a future engineer may ask to see them.

Before you call an engineer
Leave the units and pipework where they are. Disconnecting a system means dealing with refrigerant, which only a qualified engineer can do, and the electrics need care too. If you need something moved, we can quote for it.
Keep a note of anything odd: 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.
What happens on the day
Where something has to be switched off during the work, we agree it with you first, so you can plan around it. In a business, work can often be done one area at a time. On site, it takes anything from a day or two for a small office to several weeks of phased work on a large building. For a village like Wonersh, tell us about narrow lanes, gates and parking when you book.
- We start with the details of the building and the problem.
- A site survey confirms the heat load, the layout and the access.
- The options, cost and timing are set out in a fixed-price quote.
- We install around your hours, phased where necessary.
- The system is commissioned and maintenance can be arranged.
Preparing for the visit
- Dig out any previous service or F-Gas records
- Clear access to the fuse board
- Keep pets and children away from the work area

Looking after it afterwards
Looking after the system is mostly common sense. Our tips:
- Agree sensible control settings for each area
- Track when the next TM44 inspection is due
- Book a maintenance contract to keep servicing on schedule
For systems that require leak checks, the first date goes in the diary and can include it in a maintenance contract.
Train staff to use the controls sensibly. Systems fighting each other, or set to extremes, waste effort and correct settings avoid it.
Let and managed properties
Records are where property maintenance often slips. Each visit produces a dated record, with F-Gas records wherever refrigerant work is involved, ready for a tenant, a buyer or an inspection.
The F-gas rules share responsibility for leak checking between the equipment’s operator and the service technicians. Where a building is let or managed, the lease or contract should make clear who looks after the system and we’re happy to deal with whoever it is.
