    Access Control for Blocks of Flats in London: A Complete Guide

    Access control in a block of flats needs to work reliably for dozens of residents while still being manageable from a landlord or building manager's perspective. Here's what works.

    Why Blocks of Flats Need Proper Access Control

    A shared entrance in a block of flats without proper access control is a security weak point. Tailgating — where an unauthorised person follows a resident through the door — is one of the most common ways intruders gain access to residential buildings. Parcel thieves, rough sleepers, and ex-residents with keys are all real risks that a well-designed access control system addresses.

    Beyond security, access control also simplifies management. Instead of cutting keys for new tenants and changing locks when tenants leave, you simply add or deactivate a fob on the system.

    Best Options for Blocks of Flats

    • Fob entry system — Each resident receives a proximity fob that unlocks the communal entrance. Lost fobs are deactivated at the click of a button — no lock changes required. The most practical system for blocks of 4–20 flats.
    • Video door entry — A camera and intercom panel at the entrance; each flat has a monitor or handset. Residents can see and speak to visitors before releasing the door. Standard in purpose-built blocks and widely expected by tenants.
    • App-connected video entry — The video feed and door release work through a smartphone app. Residents don't need a handset in their flat, and landlords can manage the system remotely. Ideal for conversions where running handset cables to each flat would be disruptive.
    • Combined fob + video entry — Residents use fobs for day-to-day access; visitors use the intercom panel to call up. The most comprehensive solution for larger blocks.

    What About Fire Safety?

    Any electronic door lock on a fire escape route must be connected to the building's fire alarm system. In the event of a fire alarm activation, the locks must release automatically so the doors can be pushed open for evacuation. This is a legal requirement and must be incorporated into the system design.

    Security Red Alert always integrates access control systems with the building's fire alarm where required — it's not an optional extra, it's standard practice.
