Home Security Systems in London
Professional home security systems for houses, flats, apartments and converted properties throughout London, professionally installed by On Call’s trained in-house engineers.
Why Choose On Call in London?
London requires a different approach to home security because the type and layout of properties can change dramatically from one area to the next. Apartments, converted Victorian properties, terraces, townhouses, mews homes and larger suburban properties can all present different access points and installation requirements.
Communal entrances, multiple floors, shared access, restricted parking and limited external space can also influence how a system should be designed. Our engineers consider those practical details before recommending the equipment and positioning for your home.
With more than 20,000 homes protected nationwide, On Call combines professional installation with straightforward advice, smart technology and responsive support after your system has been fitted.

Security Designed Around London Homes
From central apartments to larger homes in outer London, we assess the layout and access arrangements of the property before recommending the equipment and coverage that makes sense.
Flats & Apartments
Apartments can involve communal entrances, shared corridors, balconies, multiple occupants and limited external access. Security needs to work around both the individual home and the wider building.
Terraces & Converted Homes
Victorian terraces, townhouses and converted properties can include basement access, rear gardens, side passages, multiple floors and older layouts that require careful equipment positioning.
Suburban & Larger Homes
Larger properties in outer London may have driveways, garages, gardens, extensions and several external access points that require broader security coverage.
Installers You Can Trust
London installations often require additional planning around restricted parking, communal areas, narrow access, older building materials and properties spread across several floors. These factors can affect both how the engineer reaches the property and how the finished system should be configured.
Our engineers install, configure and test the complete system before showing you how everything works. The goal is a professional installation that provides effective coverage without adding unnecessary complexity to your home.

Home Security Across London
Metropolitan Police detectives investigated a residential burglary in Bromley in which around £500,000 worth of gold was stolen from a home. Three offenders entered the property through a forced bathroom window while the owners were inside.
The incident demonstrates how a single vulnerable access point can be used to enter an occupied home. Window protection, perimeter detection and a professionally designed alarm system can all help strengthen vulnerable parts of a property and provide earlier warning of an attempted break-in.
