Things to check in Dover
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.
Neighbours and noise
Outdoor units near flats — common above shops — need careful siting so noise at neighbours' windows stays low. We choose positions and quieter units with that in mind.
Working hours
Most Dover businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
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.
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 from businesses in Dover
How much does commercial air conditioning cost in Dover?
A single wall-mounted split typically costs £1,650–£2,795 plus VAT installed in Dover, and a ceiling cassette £2,450–£5,695 per unit. A small shop or office with two to four indoor units usually comes to £5,695–£18,995 plus VAT.
Do you also cover Folkestone, Deal and Canterbury?
Yes. Alongside Dover, we also cover Folkestone, Deal and Canterbury. 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.
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.
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.
