How we price commercial air conditioning
Every job gets its own quote. This is what makes a difference:
- One-off work versus a regular service cycle
- What electrical work the job needs
- The equipment or parts the job needs
What you pay reflects the actual work. That is why we look at the job first, from photos or on a survey, and why the quote is fixed before any work starts.
Helping us quote
What to send for a quote:
- The address and the type of property
- The outside wall, roof or yard where the outdoor unit sits or would go
- A close-up of the unit’s label showing the model number
Getting a quote is straightforward. Send a few details and photos, and we reply the same working day. If we need to see the property first, we book a survey at a time that works for you.
Commercial air conditioning in Anstey, done properly
Commercial air conditioning comes with F-gas duties for the operator. Systems at or above 5 tCO2e need leak checks, and records kept of the checks and the work done. We handle the checks and records and remind you when the next is due. The work covers ceiling cassettes, VRF systems and server and comms room cooling, and the jobs we see most are R410A systems getting dearer to top up and leak check schedules that have slipped.
For a business near Anstey, outdoor units usually have room at the back of the building, out of sight and away from neighbours.
We’re an F-Gas certified company, NICEIC approved for electrical work, MCS certified for heat pumps and a Checkatrade member. Refrigerant work is done by engineers who hold the F-gas qualifications the law requires.

Cooling for Anstey businesses
Anstey’s centre falls inside the Anstey Conservation Area. Listed buildings are part of the picture here: about 25 within half a mile of the centre, such as Church of St George (church of England) (grade I). Heritage protection changes what an install can involve, so the survey looks at your address first and tells you plainly whether consent is likely. About 34 miles out from central London, Anstey is part of the South East area we work across.
A bursar or site manager at a school like Anstey First School will want the install planned around the school calendar, and we work to that. For a church or hall like Church of St George, any outdoor unit needs the right consents first.

What owners can safely do
On air conditioning, the filters in the indoor unit are normally the one part owners can clean where the manufacturer’s manual explains how. With the power off, they lift out, can be vacuumed or rinsed and must be fully dry before they go back. On a heat pump, the equivalent is keeping the outdoor unit clear and checking the controls.
Some faults have simple causes you can check first: is the system in the right mode, is the set temperature sensible, are the remote’s batteries working and has the breaker tripped. If the breaker trips a second time, leave it off and ring us on 07833 053749 or fill in the contact form.
What we do, step by step
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. On the day, both are in the same hands. The work takes from a couple of days for a few cassettes to a planned programme for a whole building. Seeing the property in pictures first means the trip to Anstey can be planned properly.
- We visit the site to look at the building, how it’s used and what the system needs to do.
- You get a fixed-price quote with the equipment, the layout and the programme set out.
- Dates are set with you so trading, teaching or treatment carries on, using evenings, weekends or phases where it helps.
- Indoor and outdoor units, pipework, condensate and controls are installed and the electrics connected.
- We commission the system, record the refrigerant details and hand over the controls and documents.
Getting ready for the visit
- Unlock any gate, garage or side passage we need
- Keep pets and children away from the work area
- Dig out any previous service or F-Gas records

FAQs for Anstey
Will you come out to Anstey?
Yes. Anstey is within the area we cover across London and the South East. Visits to smaller places are planned so the engineer arrives with what the job needs.
Do you cover Anstey for commercial air conditioning?
Yes. We work across London and the South East from our base in East Grinstead, and Anstey is part of that. Tell us a little about the job and we will take it from there.
Will I need planning permission?
Not necessarily. Permitted development can cover a heat pump on a house, including an air-to-air system that heats as well as cools since 2025, provided the conditions are met. Permission is more likely to come up for cooling-only units, listed buildings, flats and road-facing positions in conservation areas, and we tell you at the survey. This is general information, not legal advice.
Are you TM44 assessors?
No, the inspection needs an accredited energy assessor. We help before and after, preparing the system and acting on the report.
Who is responsible for leak checks?
The operator of the equipment, working with qualified engineers. Systems below 5 tCO2e fall outside the set leak check intervals, while larger ones need checks at least every 12 months, or every 6 months from 50 tCO2e. We’ll work out which band applies to yours.
How much does commercial air conditioning cost?
Each commercial job is surveyed and then priced. That lets us size the system properly and plan the work and you get a fixed price.
How long does a commercial installation take?
It takes a few days for a small shop or office, longer for VRF across several floors. The size of the building, the system and any phasing make the biggest difference, and we set out the timing with your quote.
What a customer said
“Very professional from the initial survey through to installation. The engineer explained everything clearly and the quote was exactly what we paid. Would not hesitate to recommend AirCon Doctor.”
