How much does it cost to replace air conditioning in Greenwich?

Air conditioning replacement is removing an old system — often one using R22 or R410A refrigerant — and installing new, more efficient equipment, re-using pipework where it is safe and compatible.
Working in Greenwich

How it works in Greenwich
Survey
We record what is installed, its condition and refrigerant, and what can be re-used.
Plan the swap
Removal and installation are scheduled to keep downtime short.
Recover and remove
Refrigerant is recovered into certified cylinders and the old units removed. We keep work areas in Greenwich screened and tidy at the end of each day.
Install and commission
New units are fitted, tested and commissioned with fresh records.
Before you book in Greenwich
Pipe re-use
Re-use depends on pipe size, condition, cleanliness and the new refrigerant. We test before relying on it.
Shared buildings
In multi-let buildings, roof space, risers and plant areas are often controlled by a managing agent. We work to their permits and method-statement requirements.
Disposal
Old refrigerant must be recovered by certified engineers and the units disposed of as waste electrical equipment.
Conservation areas
Historic streets and listed buildings in and around Greenwich are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Types of premises we cover in Greenwich
- Offices: zoned cooling and heating for open-plan floors, meeting rooms and comms rooms.
- Salons and spas: comfortable salons and treatment rooms despite dryers, lamps and steam.
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Restaurants and cafés: dining rooms that stay comfortable next to a hot kitchen and a busy service.
Compliance in England: refrigerant work falls under GB F-gas rules, and buildings with more than 12 kW of air conditioning in total need a periodic energy inspection (often called TM44).
Questions about replacement and upgrades in Greenwich
How much does it cost to replace air conditioning in Greenwich?
Guide prices in Greenwich run from about £2,095 to £5,695 per indoor unit, plus VAT. A typical job (replacing a 3–4 unit system, re-using sound pipework) costs £7,595–£18,550 plus VAT. We fix the price in writing after a free survey.
Do you also cover Blackheath, Canary Wharf and Catford?
Yes. Alongside Greenwich, we also cover Blackheath, Canary Wharf and Catford. Each has its own page with local guide prices.
Which postcodes do you cover in Greenwich?
All of them, including SE10. Give us your postcode when you enquire and we will confirm the visit details.
Is it illegal to use R22 air conditioning?
No — you can keep running an R22 system, but it cannot be maintained with virgin or recycled R22, so most repairs involving the refrigerant circuit are no longer possible.
Will a new system be cheaper to run?
Usually. Modern inverter systems are considerably more efficient than equipment from 15–20 years ago, though savings depend on use.
