How we handle commercial air conditioning in West Grinstead
We design, install and look after air conditioning for businesses in West Grinstead and across West Sussex. That includes offices, shops, restaurants, hotels, schools and server rooms and we choose the system to suit the space and the way it’s used. The work covers ducted systems, server and comms room cooling and wall-mounted split systems, and common reasons people get in touch are changes of use that need a new layout and work raised by a TM44 inspection.
Around West Grinstead, commercial jobs tend to be pubs, shops, halls, surgeries and farm or rural businesses. Older buildings may be listed or in a conservation area, so we check the planning side first.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we explain those terms on your quote. Terms differ from brand to brand, and we’re happy to talk you through them.

Managing agents and facilities teams in West Grinstead
If you look after several properties, we can quote and plan the work across all of them. Each property gets its own records, so the files stay tidy.
Keeping records across a portfolio is half the battle. Every visit is written up, plus the F-Gas records where refrigerant is involved, so you can show what was done and when.
Common questions in West Grinstead
Can I fit air conditioning in West Grinstead without planning permission?
The answer turns on the property and where the outdoor unit would sit. The half-mile around the middle of West Grinstead holds about 10 listed buildings and structures. 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 Horsham council, which is usually the planning authority for West Grinstead when it matters.
Do you cover smaller places like West Grinstead?
Yes, smaller places are covered as well as towns. We are based in East Grinstead and plan each visit so the job can be finished in one trip where possible.
Will I get records for the system?
Yes. You get a written record of every visit, including F-Gas records for any refrigerant work. File them with the system’s paperwork.
Can I do any of the installation myself?
Anything that involves the refrigerant needs an F-Gas qualified engineer from a certified company. That is the law, not just our preference, and manufacturers expect it for their warranty too. We can quote for the whole job, from supply to commissioning.
Do I need to service the system to keep the warranty?
It can, for some brands. Send us the make and model and we will tell you what the manufacturer expects and stick to the interval they set.
Can landlords and managing agents book you?
Yes. We work for homeowners, landlords, letting and managing agents, and businesses of every size across London and the South East. Let us know who the records should go to.
Can you install out of hours?
Yes, the programme is built around the site. Every type of building has its own pattern, and we plan for them.
How the visit works
Each visit runs to the same pattern: agree the plan on site, protect the area, carry out the job, check the system and talk you through it. The visit itself takes a few days for a small shop or office, longer for VRF across several floors. We plan the trip to West Grinstead around you.
- We survey the site and talk through how each area is used.
- You get our recommendation and a fixed price.
- We agree the timing, with evening, weekend or phased work as needed.
- We install the units, pipework, drainage, electrics and controls.
- Commissioning and handover follow, with the F-gas records and manufacturer paperwork.
How to prepare
- Tell us about parking and loading
- Mention any roof access, ladders or high-level work
- Keep pets and children away from the work area
Getting a quote
Photos are the fastest route to a quote: the inside and outside of the property where the work is, plus the rating plate of any unit already there. Add the address and what you’d like done, and many jobs can be priced from that.
Advice
Keeping the system healthy
A little care keeps the system in better shape. We recommend:
- Diary TM44 inspections in advance
- Keep F-gas records together and up to date
- Agree sensible control settings for each area
For systems over 12 kW, keep track of the 5-yearly TM44 inspection. When it comes round, we can get the system ready and carry out the recommendations.
Replace ageing systems on your own timetable especially where top-up refrigerant is getting harder to buy.

When to call us in West Grinstead
When a space is refitted or its use changes, the old layout may no longer work. New partitions, more staff or different equipment change the heat load and the system needs to match the new layout.
If any of these sounds familiar, it’s worth a diagnosis:
- Fit-outs and refurbishments that need new air conditioning
- Commercial systems near the end of their life
- Comms rooms without enough cooling
For a church or hall like Shrine Church of Our Lady of Consolation and St Francis, any outdoor unit needs the right consents first.
What your quote should include
