Alarms & Monitoring in Croydon
Intruder alarm installation covers fitting a system of door and window contacts, motion sensors and a control panel that detects unauthorised entry, with an option to connect the system to a 24-hour monitoring service that can alert keyholders or the police.
In Croydon, that covers Purley, Coulsdon, South Croydon, Addiscombe, Selsdon, Shirley, Thornton Heath, Sanderstead, Waddon. Croydon combines a dense town centre and tower-block skyline with substantial suburban housing across Purley, Coulsdon, Addiscombe and Shirley, plus the Victorian and Edwardian terraces closer to South Croydon and Thornton Heath. Its position on the A23/M23 corridor puts it within easy reach of our Surrey and Sussex teams, and it borders Sutton, Bromley and Reigate & Banstead.

Areas we cover in Croydon for alarms & monitoring
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.

What's the difference between a monitored and unmonitored alarm?
