Before you book in Welling
Access and parking
Town-centre jobs in Welling 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.
Conservation areas
Historic streets and listed buildings in and around Welling are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Working hours
Most Welling businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
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.
Two rules matter for most businesses in England: GB F-gas rules (leak checks from 5 tonnes CO2e) and the periodic energy inspection for more than 12 kW of air conditioning.
Questions from businesses in Welling
How much does commercial air conditioning cost in Welling?
A single wall-mounted split typically costs £1,850–£3,150 plus VAT installed in Welling, and a ceiling cassette £2,750–£6,350 per unit. A small shop or office with two to four indoor units usually comes to £6,350–£20,995 plus VAT.
Do you also cover Bexley, Eltham and Thamesmead?
Yes. Alongside Welling, we also cover Bexley, Eltham and Thamesmead. 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.
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.
