Things to check in Derby
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 Derby 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.
Leased premises
If your Derby premises are leased, the landlord's written consent is usually needed for external units, wall penetrations and roof access. We provide drawings and data sheets for the request.
Conservation areas
Historic streets and listed buildings in and around Derby 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).
Questions from businesses in Derby
How much does commercial air conditioning cost in Derby?
A single wall-mounted split typically costs £1,395–£2,395 plus VAT installed in Derby, and a ceiling cassette £2,095–£4,850 per unit. A small shop or office with two to four indoor units usually comes to £4,850–£16,150 plus VAT.
Do you also cover Belper, Ilkeston and Heanor?
Yes. Alongside Derby, we also cover Belper, Ilkeston and Heanor. Each has its own page with local guide prices.
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.
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.
