Commercial air conditioning in City of London, done properly
Heating, cooling and fresh air often go together. Most modern systems can heat and cool, and ventilation and MVHR can be designed alongside for a joined-up system. The work covers server and comms room cooling, ducted systems and VRF systems, and people most often call us about buildings that can’t close for the work and systems over 12 kW due a TM44 inspection.
London buildings in City of London can have little space for outdoor plant, so condensers often go on roofs, in light wells or in plant rooms. VRF systems can serve many indoor units from a small number of outdoor units.
The records are your system’s health record: what was fitted or found, what was done and when. If anything goes wrong later, it helps the next engineer and the manufacturer, so keep it safe.

City of London: your questions answered
Do I need planning permission for air conditioning in City of London?
It depends on the property. The centre of City of London is in the Guildhall Conservation Area. Put simply: reversible systems on houses can be permitted development, cooling-only ones can’t, 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 the City of London Corporation, normally the authority for City of London.
Can you fit air conditioning in a London flat in City of London?
Often, yes, but the lease and the freeholder normally have a say. Permitted development rules for flats are tighter than for houses, so we check the outdoor unit position and give you the details to send to the freeholder or managing agent.
Can you look after our air conditioning after it’s installed?
Yes, with visits planned around the site. There’s also a 24/7 emergency line for breakdowns.
When is a TM44 inspection required?
Where the air conditioning is over 12 kW, an inspection is needed at least every 5 years. It’s carried out by an accredited energy assessor and we can help before and after.
What types of commercial air conditioning do you install?
Wall-mounted, multi-split, ducted, cassette and VRF systems from the major manufacturers. We explain the options after a site survey.
Who has to arrange F-Gas leak checks?
Whoever operates the equipment, together with the technicians who service it. Larger systems need regular checks: at least every 12 months from 5 tCO2e and every 6 months from 50 tCO2e. We can tell you which band your system falls into.
Is the equipment covered by a warranty?
It’s the manufacturer’s, and the terms are theirs. Some terms depend on regular servicing by a qualified engineer, so keep your service records.

What happens on the day
Anything involving refrigerant is handled by F-Gas qualified engineers, as the law requires, while the electrical side is covered by our NICEIC approval. So on the day, you don’t need a separate electrician for the electrical side. On site, it takes a matter of days for a modest fit-out, with larger buildings phased floor by floor or zone by zone. Managed buildings in London often need contractors booked in, and we can deal with the agent for a job in City of London.
- You tell us about the building and what’s needed.
- 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.
- Installation goes ahead around the business.
- The system is commissioned and maintenance can be arranged.
How to prepare

Advice
Cooling for City of London businesses
Food Standards Agency data counts about 3,230 restaurants, cafés and canteens, about 129 hotels and guest houses and about 90 schools and colleges within roughly a mile and a half of the centre of City of London. Each of those is a different cooling job, from kitchen heat to quiet bedrooms and server rooms. The Valuation Office Agency’s council tax figures date about 40% of homes in and around City of London to the post-war years, 1945 to 1972, and about 98% of households live in flats, according to Census 2021 figures. In mixed streets, commercial outdoor units have to be placed and sized with the homes nearby in mind. London commercial jobs normally involve a landlord or managing agent, and plant space is often tight.
For a surgery or clinic in the London Bridge Hospital area, a planned maintenance contract keeps the system clean and its records up to date. For a church or hall like St Olave Old Jewry, any outdoor unit needs the right consents first.

What happens if it’s left?
When the cooling can’t keep up, staff, customers and equipment all feel it. Planning a replacement or upgrade before the summer is easier than reacting in a heatwave. If a lease or managing agent is involved in City of London, start the conversation early.

What you can do yourself, and what needs us
Never try to top up, release or handle refrigerant yourself. Under the F-gas rules, engineers need their own qualifications and the company must be certified, and refrigerant lines can cause cold burns. If you suspect a leak, switch the system off and call us.
Owners can handle the everyday basics: keeping the outdoor unit clear, checking the mode and set temperature, and the routine cleaning in the manual. Opening up the units, the electrics and the refrigerant circuit are a job for us.
Landlords, agents and facilities managers
Larger air conditioning systems in buildings need more than servicing: systems with an effective rated output over 12 kW need a TM44 inspection by an accredited energy assessor at least every 5 years. We arrange the inspection, get the system ready and put right anything it picks up.
From a single flat to a whole estate, you get the same standard: diagnosis, a fixed price, access agreed with the people on site and paperwork at the end.
From one of our customers
“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.”
