17 Home Security Tips to Protect Your London Home in 2026
Home burglary in London remains a serious concern despite improvements in some boroughs over recent years. The methods burglars use in 2026 have evolved — opportunist attacks on poorly secured UPVC doors remain common, but there is also growing use of relay attacks on keyless vehicles and network scanning of poorly secured smart home systems. This guide covers physical and digital security measures that make a genuine difference. Our 24/7 residential locksmith service can implement all physical security recommendations.
Physical Door & Lock Security
1. Upgrade to an Anti-Snap Lock (Highest Priority for UPVC Doors)
If your UPVC door has a standard euro cylinder, lock snapping is your biggest single risk. A burglar can snap a standard cylinder and open the door in under 30 seconds. Upgrade to a TS007 3-star anti-snap lock — the most impactful single security improvement for the majority of London homes.
Cost: £110–£175 per lock fitted. Read the full guide: Anti-Snap Locks for London Homes 2026
2. Fit a BS3621 Deadlock on All Wooden External Doors
For timber front and back doors, a British Standard BS3621 mortice deadlock is the baseline requirement for all UK home insurance policies. If your door doesn't have one, you may be uninsured. Our lock replacement service fits compliant deadlocks to all timber door specifications.
3. Check and Upgrade Your Door Frame
A door is only as strong as its frame. Most kick-in attacks succeed not by defeating the lock but by splitting the door frame around the keep plate. Door frame reinforcement strips (£60–£120 fitted) make kick-in attacks significantly harder.
4. Fit Hinge Bolts on All External Doors
Exposed door hinges can be attacked with a chisel. Hinge bolts — small steel bolts that engage into the frame when the door closes — prevent the door from being forced even if the hinge is removed. Cost: £40–£70 fitted.
5. Secure Patio Doors and Sliding Doors
Patio doors are common points of entry. Fit anti-lift blocks to prevent the door being lifted off its track, key-locking bolts at top and bottom, and consider a floor-mounted bar for secondary reinforcement.
6. Fit Window Locks on All Accessible Windows
Ground floor and easily accessible upper-floor windows need key-operated window locks. This is a standard insurance requirement. Our security upgrades service covers window locks across all property types.
Smart Home & Technology Security
7. Install a Smart Lock with App Access Logging
Smart lock installation in London has become mainstream in 2026. Smart cylinders (Ultion Smart, Nuki, Yale Conexis) offer app-controlled access, unique codes per person, entry logs with timestamps, and auto-lock. If a cleaner, contractor, or Airbnb guest had access to your property, you can see exactly when they entered and left.
Cost: £220–£550 fitted depending on system and compatibility.
8. Set Up a Video Doorbell With Cloud Storage
A video doorbell (Ring, Google Nest, Arlo, Eufy) deters opportunist burglars and captures footage if an attack occurs. In 2026, the Metropolitan Police has a formal partnership with Ring through the Neighbours app — footage can be shared directly with officers investigating incidents in your area.
Key consideration: enable cloud storage, not just local storage. Local storage devices are often stolen during the same burglary that the camera was meant to prevent.
9. Use AI-Powered CCTV With Person Detection
Standard motion-trigger CCTV generates too many false alerts (cats, passing cars) to be monitored effectively. AI-powered cameras (Google Nest, Ring with Ring Protect Pro, Arlo Pro 5S) use on-device processing to distinguish people from objects, send only relevant alerts, and can recognise familiar faces.
10. Secure Your Wi-Fi and Smart Home Hub
Your router is the entry point to every smart device in your home. Protect it: - Change default admin credentials immediately on any new router - Use WPA3 encryption if your router supports it - Set up a separate guest network for smart home devices, isolating them from your primary network - Update router firmware regularly
If you ever have a suspected break-in, change your Wi-Fi password immediately — the router admin label is visible to anyone who entered.
Deterrence and Environmental Design
11. Install Perimeter Lighting With PIR Sensors
PIR (passive infrared) motion-activated lighting at all approach points removes the cover of darkness that burglars depend on. Position lights to cover side passages, back gates, and car parking areas. Smart lighting (Philips Hue, Ring Floodlight Cam) can trigger alerts on your phone when activated.
12. Use Timer-Controlled Lighting When Away
Smart plugs or timer switches on interior lamps create the impression of occupation. In 2026, smart lighting systems (Philips Hue, LIFX) can simulate natural occupancy patterns — varying timing randomly each day rather than switching on and off at the same time.
13. Review Your Front Perimeter Planting
Tall, dense hedges and shrubs give cover to someone working on your front door. Keep front garden planting below waist height. A gravel path or driveway makes silent approach to the front door difficult and alerts you to visitors.
14. Secure Your Garage — Including the Internal Door
Garages are frequently targeted as secondary entry points to the main house. The internal door connecting your garage to the house is often hollow-core and poorly secured. Fit it with a BS3621 deadlock via our lock repair service and treat it with the same security priority as your front door.
Vehicle and Personal Security
15. Protect Against Relay Attacks on Keyless Cars
Relay attacks on keyless-entry vehicles are a growing problem across London in 2026. Criminals use signal amplifiers to relay the key fob's signal from inside your home to an accomplice at your car, unlocking and starting it without the physical key. Store keyless fobs in a signal-blocking pouch (Faraday cage) — these cost under £10 and are highly effective.
16. Don't Advertise Absence on Social Media
Posting that you're on holiday, away for the weekend, or attending an event tells burglars exactly when your property is empty. Review your privacy settings — and consider whether your location tags, stories, or check-ins could reveal your absence to someone monitoring your profile.
Documentation and Preparedness
17. Register Valuables and Get a Free Security Survey
Mark valuables with your postcode and house number using a UV pen. Register items on the Immobilise national property register (free) — police use this database to return recovered property and support prosecutions.
London Locksmith Pro offers a free home security survey. Our locksmiths will assess every door, window, and access point, identify vulnerabilities, and recommend targeted improvements in priority order. Call 07984 547185 to arrange.
