Emergency Security Repairs UK Guide¶

What to do when your locks, doors, or windows fail - and how to find a trusted repair service fast.

Immediate Steps After a Security Failure¶

If a lock jams, a door frame rots, or a window shatters, you need a rapid fix. The Master Locksmiths Association (MLA) operates a 24/7 hotline for accredited locksmiths - average call-out is £60 - £120 plus parts. For out-of-hours work, expect a 50 - 100 % surcharge. Keep a portable door lock (Addalock, £14.99) as a temporary measure. If the damage is from a break-in, the police will provide a crime number - essential for insurance claims. Secure the opening with plywood (6 mm sheet from £12 at B&Q) screwed from the inside.

Choosing a Trusted Repair Professional¶

Never hire a locksmith solely from a Google ad - 80 % of emergency locksmith complaints involve misleading pricing, according to TrustMark. Use the MLA finder, Checkatrade, or Which? Trusted Traders. A reasonable price for a standard lock replacement is £70 - £150 including parts and call-out. For doors, a carpenter from the Federation of Master Builders costs £200 - £400 for a replacement PVCu door. Keep receipts: insurers will reimburse emergency repairs up to £500 without prior authorisation (check your policy). Brisant Ultion cylinders (£85 - £110) are snap-resistant and recommended by police.
