- IT rooms that need resilient cooling

- Leak check schedules that have slipped
How we handle commercial air conditioning in Whitehall
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 do not carry out the inspection itself, but we prepare the system and do the work it recommends. If the problem is older systems on refrigerants that are getting scarcer and leak check schedules that have slipped, we can sort it out.
If you run a village hall or similar building near Whitehall, heating and cooling that warms up fast suits a space used on and off, and it can heat as well as cool.
Whatever the visit, you get a written record: commissioning details and F-Gas records for a new system, a note of the fault and the fix for a repair, or a service record. Keep it with the system’s paperwork so it’s to hand next time.

For landlords and property managers
Records are where property maintenance often slips. Each visit produces a dated record, plus the F-Gas records where refrigerant is involved, ready for a tenant, a buyer or an inspection.
We work for landlords, letting agents and managing agents as well as homeowners and businesses. Tell us who the contact on site is and who should receive the paperwork and we will copy in whoever needs it.
Whitehall questions
Is Whitehall in your area for commercial air conditioning?
Yes. Whitehall is one of the places we cover. Tell us a little about the job and we will take it from there.
Is Whitehall within the area you cover?
Yes. Whitehall is within the area we cover across London and the South East. Send a few details and pictures, and we reply the same working day.
Can you look after our air conditioning after it’s installed?
Yes. A contract keeps the system serviced and any required leak checks on schedule, with records kept for each visit.
Can you come out in an emergency?
Yes, 24/7. Call the emergency line and tell us the make, the symptoms and any error code, and we’ll advise on what to do next.
Is planning permission needed for the outdoor unit?
Not always. 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. Cooling-only units, listed buildings, flats and road-facing spots in conservation areas are where it typically comes up, and we tell you at the survey. This is general information, not legal advice.
How do you keep the place clean during the work?
We put dust sheets over floors and furniture near the work first, and we tidy up as we go. At the end, we clear up and show you what we’ve done.
Which manufacturers do you install and repair?
Mitsubishi Electric, Daikin, Fujitsu, Panasonic, Toshiba, LG, Samsung, Mitsubishi Heavy Industries, Hitachi and others. For new systems, we recommend a brand and model to suit the job and tell you why.
Commercial air conditioning in Whitehall: local notes
Listed buildings are part of the picture here: about 6 within half a mile of the centre, such as The Parish Church of St Mary (grade I). That matters for air conditioning: permitted development doesn’t apply within the grounds of a listed building, in a conservation area the outdoor unit can’t go on a wall or roof facing a road, and a unit used only for cooling is not covered at all, so we check with the planning team at Horsham council, which normally handles Whitehall where needed. At about 38 miles from central London, Whitehall sits inside the area we cover across London and the South East.
Schools such as Shipley CofE Primary School typically have the work done in the holidays, when classrooms are empty. If you look after a church or hall such as The Church of St Mary the Virgin, an air-to-air system that warms up quickly can suit a building used on and off, subject to the right consents.
Whitehall is about 6 miles south-west of Horsham, in West Sussex. From the centre of Whitehall to the outskirts, our engineers cover commercial air conditioning, from a single room to a whole building.

What we do, step by step
The first job on site is protection: dust sheets over floors and furniture near the work and nothing is moved without asking you. After that, anything electrical is made safe and we start. It takes a matter of days for a modest fit-out, with larger buildings phased floor by floor or zone by zone, and we clear up before we go. Rural lanes and tight entrances are worth mentioning before a visit to Whitehall.
- An engineer walks the building with you to understand its layout, its users and its heat sources.
- A fixed-price quote follows, covering the system type, the layout and the timing.
- Dates are set with you so trading, teaching or treatment carries on, using evenings, weekends or phases where it helps.
- The system goes in, from units and pipework to drainage, wiring and controls.
- Commissioning, F-gas records and a handover of the controls finish the job.
Getting ready for the visit
- Let us know where we can park and unload
- Find the manual or the paperwork for the system, if you have it
- Arrange for someone to be there to let us in
How to get a quote
VAT is set out clearly on every quote, and the rate that applies to your job is stated. VAT can differ between homes and businesses and between kinds of work, so we confirm it on the quote. For a fixed-price quote, phone us on 07833 053749 or email us.
Advice
Owner checks or an engineer?
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Anything inside the units, the electrics and the refrigerant is engineer’s work.
Good habits make our visits easier, not unnecessary. Clean filters and a clear outdoor unit help the system run as it should, but the refrigerant circuit, the electrics and the parts you cannot see still need an engineer at the interval the manufacturer recommends.
Why deal with it now?
R410A systems are still legal to repair, though supply of the gas is tightening. It’s better to replace on your terms than after a breakdown. Booking before summer means the work in Whitehall is done before the hot weather.
A single unit or a whole estate, the quote is built the same way: the work involved, the access and the equipment. The price is fixed before any work starts, with VAT shown clearly.
