Southall and surrounding areas

That includes premises in UB1 and the surrounding districts. We also work in nearby Greenford, Heston and Hayes.

Local points to consider
Conservation areas
Historic streets and listed buildings in and around Southall 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 Southall 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.
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.
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).
Common questions in Southall
How much does commercial air conditioning cost in Southall?
A single wall-mounted split typically costs £1,850–£3,150 plus VAT installed in Southall, 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 Greenford, Heston and Hayes?
Yes. Alongside Southall, we also cover Greenford, Heston and Hayes. 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.
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.
