What to Do Immediately After a Break-In: A South London Homeowner's Guide

5 min readTrustLock Locksmith Dulwich

A burglary is disorienting. This guide gives the correct sequence of actions after a break-in in South London — from calling 999 to insurance documentation and same-night security repairs.

Do Not Go Inside If the Intruder May Still Be There

If you arrive home to find signs of a break-in and are unsure whether the intruder has left, stay outside and call 999. Only enter once police have confirmed the property is clear.

Step 1: Call 999 or 101

If someone may still be inside: 999. If it is clearly a past burglary: 101 (non-emergency). Officers will attend, take a statement, and issue a Crime Reference Number — which your insurer will require before processing any claim.

Step 2: Do Not Touch Anything

Before police attend, avoid touching surfaces, moving items or cleaning up. Photograph all damaged areas on your phone: the broken door, forced window or damaged lock, and disturbed areas inside. Do this before anything is moved.

Step 3: Call Your Insurer

Most policies require notification within 24–48 hours. Note: insurers may ask whether the entry point had a BS3621-certified lock — this affects your claim if the answer is no.

Step 4: Call an Emergency Locksmith for Same-Night Repairs

A damaged entry point must be secured the same night. TrustLock attends break-in calls across Dulwich, Peckham, Camberwell, Brixton and South London. On the same visit we can replace a damaged cylinder, temporarily board a damaged frame, and advise on security upgrades to reduce repeat risk.

What to Document for Your Insurance Claim

  • Photographs of all entry points and disturbed areas
  • List of stolen items with approximate values
  • Serial numbers of stolen electronics
  • Any CCTV footage from your cameras or neighbours
  • The Crime Reference Number from police
  • Reducing Repeat Risk

    Properties that have been broken into once face elevated risk of a second burglary within weeks. The most effective post-burglary improvements: anti-snap TS007 3-star cylinder upgrades from £65 per cylinder installed, door frame reinforcement at kick-in points, and rear gate security.

    We provide a free security assessment with any post-burglary lock replacement. Call 07984 547185 for same-day attendance.
