Points to plan for in Croydon
Noise
Fans and grilles are selected and attenuated to keep noise down.
Conservation areas
Historic streets and listed buildings in and around Croydon are more likely to need planning permission for outdoor units on visible elevations. We check with the local planning authority before work is booked.
Fire
Ducts passing through fire-rated walls or floors need fire dampers.
Working hours
Most Croydon businesses prefer noisy work outside trading hours. Early starts, evenings and weekends can be arranged and are priced up front.
