6 Questions to Ask a Locksmith Before Hiring Them
Six Questions That Could Save You Time, Money, and Trouble
Whether you’re locked out of your home, need a lock upgraded, or want a security assessment for your business, choosing the right locksmith matters. In the UK, locksmith services are not subject to mandatory licensing - which means that while most locksmiths are professional and competent, a small number are not.
Asking the right questions before you hire protects you from scams, poor workmanship, and unexpected charges. Here are the six most important.
1. Are You a Member of the Master Locksmiths Association?
The Master Locksmiths Association (MLA) is the UK’s leading trade body for locksmiths. Membership is not automatic - it requires a background check, a technical assessment, and a commitment to ongoing professional standards.
An MLA-approved locksmith:
- Has been vetted and assessed for competency
- Is subject to a code of conduct
- Carries insurance
- Can be reported to the MLA if they behave unprofessionally
You can verify MLA membership directly on the MLA website. If a locksmith claims membership but cannot provide a registration number, treat that as a warning sign.
Other relevant bodies include the Institute of Certified Locksmiths (ICL) and the Institute of Locksmithing and Security Professionals (ILSP).
2. Are You Insured?
A professional locksmith should carry public liability insurance. This protects you if any accidental damage occurs to your property during the course of the job - for example, if a door frame is damaged during an emergency entry.
Ask for proof of insurance before work begins. A reputable locksmith will have no hesitation in providing it. If they cannot or will not, look elsewhere.
3. Can You Provide a Written Quote Before Starting?
Always ask for a written quote before any work begins. The quote should include:
- The cost of labour
- The cost of any parts or materials
- The callout fee (if applicable)
- Whether VAT is included
A written quote protects you from the most common locksmith complaint: being quoted one price on the phone and presented with a much higher bill once the work is done. If a locksmith refuses to provide a written quote, this is a significant red flag.

4. How Long Have You Been Operating, and Can You Provide References?
Experience matters in locksmithing. A locksmith who has been working for several years has encountered a wide range of lock types, property configurations, and problems - and has the practical knowledge to handle unusual or complex situations.
Ask:
- How long have you been in business?
- Do you have experience with my specific lock type or door type?
- Can you provide references from previous customers, or point me to your online reviews?
Genuine customer reviews on Google, Trustpilot, or Checkatrade are also a reliable source of independent evidence about the quality and reliability of a locksmith’s work.
5. Do You Offer a Guarantee on Your Work?
A professional locksmith stands behind their work. Ask whether the locksmith offers a guarantee on:
- Workmanship - If a lock they’ve fitted fails prematurely due to a fitting error, will they return and rectify it?
- Parts - What warranty does the lock or hardware carry, and does the locksmith pass this on to you?
A locksmith who provides a meaningful guarantee is demonstrating confidence in the quality of their work. Those who hedge or avoid the question may be less confident.
6. What Identification Will You Bring?
Before you let anyone into your home or business, you’re entitled to know who they are. A professional locksmith will arrive with:
- Photo identification - A driving licence or passport if asked
- Company identification - Business cards, branded uniform, or a company vehicle
- Proof of insurance - Available on request
If you called a locksmith company and someone unknown arrives at your door, ask to see their identification and call the company to confirm they sent this person. A legitimate business will expect and welcome this caution.
