What to do after a break-in is something no one wants to think about but being prepared can make an incredibly stressful situation much more manageable. Whether you’ve returned home to find a broken window and ransacked rooms, or you were disturbed in the night, the steps you take in the hours immediately after a burglary are critical. This guide from Capital Locksmiths, an MLA-approved locksmith service based in Whetstone, covering North London for over 22 years, walks you through exactly what to do.
⚠️ If you believe the burglar may still be on the premises, leave immediately and call 999. Do not enter or confront anyone. Your safety is the absolute priority.
The Immediate Steps After a Break-In
Once you’ve confirmed it’s safe to return to or enter your property, follow these steps in order:


Immediate Security: What Does an Emergency Locksmith Do?
When Capital Locksmiths attends an emergency call-out after a break-in in North London, the first priority is to fully secure your property before anything else. This typically involves:
- Assessing all points of entry for damage or compromise
- Replacing or temporarily securing broken or forced locks
- Emergency boarding of any broken windows or damaged door panels
- Installing new cylinders or full lock replacements where required
- Advising on any further security improvements that should follow
It’s important to understand that even if a lock looks intact, a forced entry can damage the lock mechanism internally, rendering it far less secure than it appears. A professional inspection will identify any compromised hardware that needs replacing.
Upgrading Your Security After a Break-In
Once the immediate emergency is resolved, the next priority is to ensure your North London home is better protected than before. Burglars frequently return to the same property or properties in the same street within weeks of an initial break-in. Here are the most effective security upgrades:

Capital Locksmiths are approved members of the Master Locksmiths Association (MLA) – the UK’s leading trade body for the locksmith industry. MLA approval means we’ve been independently vetted for technical competence, insurance, and professional standards. When you’re securing your home after a break-in, using an MLA-approved locksmith is essential. Always check credentials before inviting any locksmith onto your property.
What Your Insurer May Require After a Burglary
Following a burglary and insurance claim, many insurers require specific security improvements before reinstating full cover or renewing your policy. Common requirements include:
- BS3621 kitemarked locks on all exterior doors
- Key-operated window locks on all accessible windows
- A functioning alarm system (some insurers require professional monitoring)
- Evidence that the point of entry has been professionally secured
Capital Locksmiths can provide written confirmation of all security work carried out, which you can submit to your insurer as documentation. Contact us if you need specific security upgrades to meet insurer requirements, we’ll advise on the most appropriate products and carry out any work quickly. For general advice on home insurance after a burglary, the Association of British Insurers provides useful guidance. The Secured by Design initiative, a UK police-backed scheme – certifies security products that meet rigorous tested standards, and is an excellent reference when choosing replacement locks. You can also find further guidance on GOV.UK’s crime reporting page for follow-up steps after a break-in.
Frequently Asked Questions
How do I know if my door frame has been damaged in a break-in?
Common signs include splintered or cracked wood around the frame or door edge, a door that no longer closes flush, visible marks or dents around the lock strike plate, or a lock that feels loose or operates differently. If in doubt, a professional inspection by Capital Locksmiths will identify any hidden damage.
Do I need to change my locks even if the burglar came through a window?
If keys were taken during the burglary, then yes absolutely. Even if they weren’t, it’s good practice to use the incident as an opportunity to upgrade your entire security provision, as your property has now been identified as a potential target.
