Commercial air conditioning, planned around how your building is used
What is commercial air conditioning?
Commercial air conditioning is cooling and heating designed for business premises — offices, shops, restaurants, gyms, surgeries and technical rooms — sized to the real heat from people, equipment, lighting and sunshine. Most systems are heat pumps, so the same equipment heats in winter and cools in summer.
We design, install and look after systems for businesses across England, Scotland, Wales and Northern Ireland, with remote and island locations by arrangement: wall-mounted splits for a single room, ceiling cassettes and ducted units for open spaces, VRF for whole floors, and dedicated cooling for server rooms. Every installation starts with a survey and a written specification, so you know the unit sizes, positions, refrigerant and price before anything is fitted.
Once it is in, we keep it running: planned maintenance, repairs, deep cleaning and the F-gas leak checks and TM44 energy inspections the law requires for larger systems.
Sized to your heat load
We calculate cooling for each zone from occupancy, IT, glazing and orientation, not just floor area.
Installed around your hours
Noisy or messy work is scheduled for quiet periods, early starts or out of hours.
Compliance handled
F-gas records, leak checks and TM44 inspections, with paperwork you can show an inspector.
One contact for install and aftercare
One point of contact from survey to aftercare, with one set of records for every system.

The two rules most businesses need to know
F-gas leak checks
If an air conditioning system holds refrigerant equal to 5 tonnes of CO2 or more, the business that controls it must have it leak-checked by a certified engineer at least every 12 months — every 6 months from 50 tonnes — and keep records for five years. For R410A that threshold is reached at about 2.4 kg of refrigerant; for R32, about 7.4 kg. More on F-gas leak checks.
TM44 energy inspections
If the air conditioning you control in a building adds up to more than 12 kW, it needs an energy inspection by an accredited assessor — at least every five years in England, Wales and Northern Ireland, with a £300 penalty for not having a valid report. Scotland has its own equivalent. More on TM44 inspections.

Common questions
How much does commercial air conditioning cost?
A single wall-mounted split typically costs £1,450–£2,950 plus VAT installed, a ceiling cassette £2,150–£4,950 per unit, and a VRF system £2,450–£4,950 per indoor unit. A small shop or office with two to four indoor units typically comes to £4,950–£16,500 plus VAT.
Is the survey free?
Yes, for new installations and replacements on the UK mainland. Remote and island locations carry a travel charge, quoted in writing first. Service, repair and inspection visits are priced before we book them.
Can you install while we stay open?
Usually. Noisy or messy work is planned for quiet periods, early starts, evenings or weekends, and work areas are screened and kept clean.
Does air conditioning heat as well as cool?
Almost all modern commercial systems are heat pumps, so the same units can heat in winter and cool in summer.
Do our systems need F-gas leak checks?
If a system holds 5 tonnes CO2 equivalent of refrigerant or more — about 2.4 kg of R410A or 7.4 kg of R32 — it needs leak checks at least every 12 months, with records kept for five years.
Do you cover the whole UK?
Yes. We work across England, Scotland, Wales and Northern Ireland. Remote island and Highland locations are covered by arrangement, with travel agreed before any visit.
