Coverage
Areas we cover in Croydon for drainage
Property styles in Croydon
Housing ranges from Victorian and Edwardian terraces near the town centre and South Croydon, through interwar semis across Addiscombe, Shirley and Thornton Heath, to larger detached houses in Purley, Coulsdon and Sanderstead. Loft conversions and rear extensions are common on the terraced and semi-detached stock, while the larger plots further south suit more substantial extension and outbuilding projects.
Planning considerations
Croydon Council (London Borough of Croydon) is the local planning authority. Several residential areas, including parts of South Croydon, Coulsdon and Addiscombe, are conservation areas, and parts of the borough's southern edge fall within the Metropolitan Green Belt, which affects extensions and new structures. As with all London boroughs, permitted development rights can also be more restricted on flats and some converted properties.

How do I know if I need a CCTV drain survey?
Recurring blockages, slow-draining fixtures across the property, or unexplained damp near ground level are common signs. A CCTV survey identifies the exact cause and location before any excavation is planned.
Who is responsible for a blocked shared drain?
Shared drains serving more than one property are usually the responsibility of the water company, while private drains serving a single property are the owner's responsibility. We can advise on which applies once the drain run is surveyed.
