Questions from Heronsgate
Can you do commercial air conditioning in Heronsgate?
Yes. We work across London and the South East from our base in East Grinstead, and Heronsgate is part of that. Tell us a little about the job and we will take it from there.
Do I need planning permission for air conditioning in Heronsgate?
It comes down to the building and the spot chosen for the outdoor unit. Central Heronsgate sits inside the Heronsgate Conservation Area. Put simply: reversible systems on houses can be permitted development, cooling-only ones cannot, listed buildings need consent, and conservation areas limit outdoor units facing a road. When your property needs a decision, we contact the planning department at Three Rivers council, usually the authority for Heronsgate.
Does my building need a TM44 inspection?
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. There’s a 24/7 emergency line for problems that cannot wait for a planned visit. Ring 07833 053749 any time and explain the problem.
Which accreditations do you hold?
We hold F-Gas company certification, which the law requires for any business working on refrigerant. NICEIC approval, MCS certification for heat pumps and Checkatrade membership sit alongside it.
Is the equipment covered by a warranty?
The manufacturer’s warranty, on the manufacturer’s terms. Each brand sets its own conditions and periods, so we explain them on your quote.
Which commercial systems do you fit?
From one wall-mounted unit to VRF across several floors. Cassettes and ducted units are common choices for open-plan and visible spaces.
How we handle commercial air conditioning in Heronsgate
There’s no single best commercial system. Wall-mounted splits suit small offices and single rooms, cassettes suit open ceilings, ducted units hide away in ceiling voids, and VRF or VRV serves many rooms from shared outdoor units. We set out the choices and the reasons behind our recommendation. Typical jobs include ageing air conditioning that keeps breaking down and systems over 12 kW due a TM44 inspection, on VRF systems, server and comms room cooling and wall-mounted split systems.
Around Heronsgate, there’s normally space for outdoor plant away from the road.
Warranty on the equipment is the manufacturer’s own, on the manufacturer’s terms, and we set them out on your quote. Each brand sets its own conditions, so we go through them with you rather than leave you to find the small print.

How it works
You don’t need to do much on the day. Someone needs to let us in and show us the units, or where they’re going, and we take it from there. Before we leave, the area is tidied and we explain what we have done. For a village like Heronsgate, tell us about narrow lanes, gates and parking when you book.
- First comes a site survey of the building, its occupancy and the heat it has to deal with.
- The written quote is fixed and lists the plant, where it goes and the order of works.
- We agree a programme that suits the site, including evening, weekend or phased installation.
- Indoor and outdoor units, pipework, condensate and controls are installed and the electrics connected.
- Finally it’s commissioned and handed over, with the refrigerant records and manuals for your files.
Preparing for the visit
- Keep pets and children away from the work area
- Name a contact who can meet us at the agreed time
- Make sure we can reach the outdoor unit, or where it will go
Getting a quote

Advice
Why it’s worth doing now in Heronsgate
When the cooling cannot keep up, staff, customers and equipment all feel it. It’s far easier to plan new work in the cooler months than to scramble when it’s hot. Waiting rarely makes an air conditioning problem smaller.
Putting several jobs into one visit can make for a more efficient booking. Tell us about everything you’d like looked at and we will price it together.

Pricing commercial air conditioning in Heronsgate
The quote reflects the job in front of us. We take into account:
- The size of the job
- What kind of system it is
- Whether we need access equipment for high-level work
No two properties are the same, so each one gets its own fixed-price quote. The system, the access, the pipe routes and the parts involved all make a difference.
What we need to know
Photos and a few facts are often enough to price a simple job. Useful things to send:
- The rating plate or label on any existing unit
- A photo of the consumer unit with the cover closed
- Photos showing the indoor unit and the space around it
Want a quote for commercial air conditioning? Please call us on 07833 053749 or write to us at info@aircondoctor.co.uk and tell us about the job. We’ll explain what we’d recommend and why, then send a fixed-price quote before you commit to anything.
Common problems we fix in Heronsgate
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.
Keep an eye out for any of the following:
- Work raised by a TM44 inspection
- Server rooms running too warm
- Planning ahead for the HFC phase-down
If you look after a church or hall such as St John, an air-to-air system that warms up quickly can suit a building used on and off, subject to the right consents.
Before booking anyone
- Whether the electrical work is done by a registered contractor, such as NICEIC approved
- Whether the manufacturer’s warranty depends on regular servicing
- Whether the quote shows VAT clearly
