Before you book in Carshalton
Working hours
Most Carshalton businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
Access and parking
Town-centre jobs in Carshalton 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 Carshalton 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.
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.
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).
