Points to plan for in Dartford
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.
Conservation areas
Historic streets and listed buildings in and around Dartford are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
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.
Access and parking
Town-centre jobs in Dartford 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.
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 Dartford
How much does commercial air conditioning cost in Dartford?
A single wall-mounted split typically costs £1,650–£2,795 plus VAT installed in Dartford, 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 Bexley, Swanley and Welling?
Yes. Alongside Dartford, we also cover Bexley, Swanley and Welling. Each has its own page with local guide prices.
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.
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.
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.
