Locksmith License UK – Everything You Need to Know

If you’re thinking about becoming a locksmith in the UK, the first question on most minds is: do I need a licence? The short answer is yes – most jobs that involve lock work, key cutting, or emergency entry require a valid licence or certification. Below we break down the exact steps, costs, and rules so you can get started without guessing.

How to Get a Locksmith Licence

1. Choose the right training provider. Look for a course approved by the Security Industry Authority (SIA). These programs usually run 3‑5 days and cover basic lock theory, practical key cutting, and health‑and‑safety rules. Many community colleges and private schools offer them, both in‑person and online.

2. Pass the SIA exam. After the course you’ll sit a written test and a practical assessment. The written part checks your knowledge of lock types, legal responsibilities, and customer service. The practical exam is hands‑on – you’ll have to demonstrate key duplication and lock opening techniques.

3. Apply for the SIA licence. When you’ve passed, fill out the online application on the SIA website. You’ll need a clear ID, proof of address, and a recent passport‑style photo. The fee is £190 for a three‑year licence (plus a small admin charge).

4. Background check. The SIA runs a basic criminal record check. If you’ve got an unspent conviction related to theft, fraud, or violence, you may be refused. This step protects customers and keeps the industry reputable.

5. Renew every three years. Keep your licence current by paying the renewal fee and completing a short refresher course. This helps you stay up‑to‑date with new lock tech like smart cylinders and biometric locks.

What the Licence Allows You to Do

With a valid SIA licence you can legally:

• Cut keys for residential, commercial, and automotive locks.
• Install, repair, and replace locks on doors, windows, and safes.
• Provide emergency lock‑out services for homes and businesses.
• Work with high‑security systems, including electronic and RFID locks, provided you have the additional specialist training.

Without a licence, you risk hefty fines and can’t work for reputable firms. Some clients – especially landlords and insurance companies – will only hire licensed locksmiths, so your earning potential depends on having it.

People often wonder if a DIY approach can replace formal training. While you can learn basic key cutting at home, the law still requires a licence for any commercial work. Skipping the licence might save you a few pounds now, but it can cost you jobs, insurance, and even legal trouble later.

If you already have a locksmith licence from another country, you’ll still need to apply for an SIA licence. The SIA may accept proof of foreign training, but you’ll still have to pass the UK exam and background check.

Ready to start? Grab a list of accredited SIA courses, set a date, and budget around £300 for training, exam, and the licence fee. In a few weeks you’ll be equipped to open doors – literally – and earn a reliable income.
