How many houses in London has security front doors?

It’s difficult to pinpoint the exact number of houses in London with security front doors, but we can make a reasonable estimate based on trends in home security.

As of recent reports, around 50-60% of households in the UK have some form of home security, including alarms, CCTV, and security doors. While this percentage includes all types of security systems and not just front doors specifically, it’s likely that a significant portion of those homes with security systems also have upgraded front doors or reinforced locks.

Considering London has approximately 3.6 million households, if we assume about 50-60% of them have some form of security door or system, that could mean anywhere from 1.8 to 2.16 million homes in London might have some form of security front doors.

However, the exact number would depend on factors such as the type of neighborhood, property value, and whether the homeowners have chosen to invest in higher security measures like reinforced or steel doors.
