Local points to consider
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.
Conservation areas
Historic streets and listed buildings in and around Dereham are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Access and parking
Town-centre jobs in Dereham 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.
Roof and height work
Flat roofs, high walls and atriums need the right access equipment and edge protection. We plan towers, MEWPs or scaffold before the job, not on the day.
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).
FAQs for Dereham
How much does commercial air conditioning cost in Dereham?
A single wall-mounted split typically costs £1,550–£2,650 plus VAT installed in Dereham, 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 Norwich, Thetford and King's Lynn?
Yes. Alongside Dereham, we also cover Norwich, Thetford and King's Lynn. 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 handle landlord consent?
We supply the drawings, unit data sheets and method of fixing your landlord or managing agent will ask for.
Can you work outside our opening hours?
Yes. Early starts, evenings and weekends can be arranged, and any extra cost is shown in the quote.
