The steps for a project in Milton Keynes
Survey
We record what is installed, its condition and refrigerant, and what can be re-used.
Plan the swap

Install and commission
New units are fitted, tested and commissioned with fresh records.
Points to plan for in Milton Keynes
Disposal
Old refrigerant must be recovered by certified engineers and the units disposed of as waste electrical equipment.
Leased premises
If your Milton Keynes premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
R22
Since 1 January 2015, R22 systems cannot be maintained using virgin or recycled R22. If one leaks, the practical fix is usually replacement.
Conservation areas
Historic streets and listed buildings in and around Milton Keynes 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 Milton Keynes
- Warehouses and industrial: cooling for offices, mezzanines, control rooms and temperature-sensitive areas.
- Pubs and bars: cooling for busy bars, function rooms and cellars, sited with neighbours in mind.

In England, systems holding 5 tonnes CO2 equivalent of refrigerant or more fall under GB F-gas rules, with regular leak checks and records; buildings with more than 12 kW of air conditioning in total also need a periodic energy inspection.
Questions about replacement and upgrades in Milton Keynes
How much does it cost to replace air conditioning in Milton Keynes?

Do you also cover Bletchley, Leighton Buzzard and Ampthill?
Yes. Alongside Milton Keynes, we also cover Bletchley, Leighton Buzzard and Ampthill. Each has its own page with local guide prices.
Which postcodes do you cover in Milton Keynes?
All of them, including MK1, MK4, MK6 and MK8. 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.
