Door Entry Systems Guide [All Articles](/blog) Door Entry # Door Entry Systems for Flats & Apartments: The Complete Guide Eagle All Security 5 October 2025 7 min read ![Video door entry system installed at a London apartment block entrance](/assets/service-door-entry-hero-Rn7ErDQS.jpg) Controlling access to your building is one of the most important security measures for anyone living in a flat or apartment. The right [door entry system](/services/door-entry-systems) keeps unauthorised visitors out while making access convenient for residents and legitimate guests. As experienced door entry installers across [North London](/service-areas/north-london), [East London](/service-areas/east-london), and the rest of the capital, we've fitted systems in everything from small conversions to large purpose-built blocks. Here's our complete guide. #### Quick Summary - → Audio intercoms start from £150–£300 per flat installed - → Video entry systems cost £250–£500 per flat with screen - → Smartphone-connected systems: £300–£600 per flat, no monthly fees - → Key fob access adds convenience without compromising security - → Freeholder/management company approval usually needed for communal installs ## Types of Door Entry Systems #### Audio Intercom £150–£300/flat - Voice communication - Remote door release - Low maintenance - Most affordable option [Learn more](/services/door-entry-systems) #### Video Entry £250–£500/flat - See who's at the door - Screen in each flat - Visual confirmation - Popular choice [Learn more](/services/door-entry-systems) #### Smartphone Connected £300–£600/flat - Video call to phone - Grant access remotely - No monthly fees - Works from anywhere [Learn more](/services/door-entry-systems) 1 ### Audio Intercom Systems The most affordable option — a visitor presses your flat's button and you speak through a handset or wall-mounted speaker. - Remote door release from inside your flat - Reliable and low-maintenance - Best for budget-conscious buildings 2 ### Video Door Entry Systems Adds a camera to the entrance panel so you can **see who's at the door** on a screen inside your flat. - Visual confirmation before granting access - Particularly valuable for ground-floor flats - Popular choice for buildings in busy areas 3 ### Smartphone-Connected Systems When someone buzzes your flat, you receive a **video call on your phone** and can grant access from anywhere. - Works via Wi-Fi or 4G — at home, at work, or on holiday - No monthly fees on most models - Increasingly popular across London #### Best value for most buildings For 2–12 flat buildings, video intercom with key fob access offers the best balance of security, convenience, and cost. 4 ### Key Fob & Code Access Many buildings combine intercoms with key fob or keycode access for residents: - Quick entry without buzzing — ideal when returning with shopping - Fobs can be deactivated if lost - Codes changed regularly for security #### Need a quote for your building?

In existing buildings, cables typically run through: - • Communal risers and ceiling voids - • Surface-mounted trunking where concealed routing isn't possible The complexity of cable routing significantly affects cost and timeline. #### Important for leaseholders If you're a leaseholder, you'll typically need approval from the freeholder or management company before installing a communal door entry system. We can provide detailed specifications and a formal quotation to support your application. ## Common Problems We Solve - **Outdated systems:** Replacing old, unreliable intercoms that no longer work properly - **No entry system:** Adding access control to buildings that currently have none - **Broken door release:** Repairing or replacing faulty electric door strikes - **Tailgating prevention:** Systems that prevent unauthorised people following residents through doors - **Integration with CCTV:** Combining door entry with [CCTV cameras](/services/cctv-installation) for comprehensive entrance security #### Key Takeaway The right door entry system depends on building size, budget, and resident needs. For most London buildings, video intercom with key fob access delivers the best combination of security and convenience. ## Get a Quote for Your Building Whether you're a resident, leaseholder, freeholder, or managing agent, we provide free site surveys and detailed quotations for door entry systems across London.
