Businesses across Hertfordshire can combine servicing with any F-gas leak checks their systems need, which saves a separate attendance.

Before you book in Hertfordshire
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.
Access and parking
Town-centre jobs in Hertfordshire often come down to access — loading restrictions, parking for the van and getting equipment onto a roof. We check this at survey and plan deliveries around it.
Working hours
Most Hertfordshire businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Conservation areas
Historic streets and listed buildings in and around Hertfordshire are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
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).
Common questions in Hertfordshire
How much does commercial air conditioning cost in Hertfordshire?
A single wall-mounted split typically costs £1,550–£2,650 plus VAT installed in Hertfordshire, and a ceiling cassette £2,295–£5,350 per unit. A small shop or office with two to four indoor units usually comes to £5,350–£17,795 plus VAT.
Do you also cover Buckinghamshire, Bedfordshire and London?
Yes. Alongside Hertfordshire, we also cover Buckinghamshire, Bedfordshire and London. Each has its own page with local guide prices.
Which refrigerant do new systems use?
Most new small split systems use R32, because new single splits under 3 kg in Great Britain cannot use refrigerants with a GWP of 750 or more. Larger systems vary by equipment.
Do you service systems you did not install?
Yes. We service most commercial makes and models; tell us the make and model if you know them.
Is the survey free?
Yes, for new installations and replacements on the UK mainland. Service, repair and inspection visits are priced before we book them.
