How to Find a Trustworthy Locksmith in the UK
Locksmith scams are a growing problem in the UK, and the trade itself is completely unregulated. Anyone can start calling themselves a locksmith tomorrow morning with no training, no background checks and no accountability. When you are locked out and stressed, that makes it easy to hire the wrong person at the worst possible moment.
The good news is that a trustworthy locksmith is not hard to recognise once you know the signs. They are happy to answer questions about vetting, they give you a written quote before starting work, they attempt non-destructive entry before reaching for a drill, and they take payment when the work is done, not before.
The Kingdom Locksmith and emergency locksmith service links are included as references, but every check in this guide should be applied to any firm before booking.
Here is what to check before you call a locksmith anywhere in the UK.
Why Finding the Right Locksmith Matters More Than Ever
Locksmith scams are not a rare event. According to the Master Locksmiths Association (MLA), there were 402 reported locksmith scam complaints in 2025, a 66% increase since 2021, with close to 30 reports arriving in January 2025 alone. Those figures only count the people who realised they had been caught out and went on to report it. The real number is almost certainly higher.
What makes this worse is the shape of the industry. Locksmithing in the UK is completely unregulated. Anyone can buy a set of tools, build a website and start trading as a professional locksmith tomorrow. No exam, no background check, no licence. The MLA estimates that around 6,500 unlicensed locksmiths are currently trading across the UK.
So when you are locked out of your home at 11pm, stressed and in a hurry, choosing the wrong person carries a very real cost. If you want to go deeper on the warning signs, read our guide on how to protect yourself from locksmith scams.
Is Locksmithing a Regulated Industry in the UK?
The short answer is no.
Unlike electricians or gas engineers, locksmiths in the UK do not need a government licence to trade. There is no legal requirement for training, qualifications or background checks, so the person at your door could have started trading last week.
The MLA exists to fill that gap. Membership requires a criminal record check, a skills assessment and regular inspection of work, but it is entirely voluntary. A locksmith can trade without it and still advertise freely online.
None of this means every locksmith is a risk. There are plenty of skilled, honest locksmiths working across the UK. It simply means the absence of regulation puts the responsibility on you, the customer, to verify who you are hiring. The good news is that verification is straightforward once you know what to look for.
7 Signs of a Trustworthy Locksmith in the UK
Treat this as your checklist and run through it before you call anyone.
1. They Are DBS Checked
A DBS check, short for Disclosure and Barring Service, reveals whether someone has a criminal record relevant to working in people's homes. It is the same check required for people who work with children or vulnerable adults.
Ask to see evidence of any claimed check before work begins, including when considering Kingdom Locksmith. A provider should answer the question directly rather than relying on an assumption.
2. They Are Straight About Fees and Payment
This is one of the clearest trust signals in the industry.
Rogue locksmiths often demand payment upfront, or add a charge simply for turning up. Ask before you book whether a call-out fee applies and when payment is expected. If you are being pressed to pay before any work has been done, something is wrong.
To understand what fair pricing looks like, read our guide on how much a locksmith costs in the UK. Comparing a quote against typical locksmith prices takes a few minutes and can save you hundreds of pounds.
3. They Give You a Written Quote Before Starting
Never accept a verbal quote from any tradesperson. Verbal quotes cannot be enforced, the price can change the moment work begins, and at that point you have very little recourse.
Ask for the total cost in writing, including labour and parts, before the locksmith touches anything. A trustworthy locksmith will offer this without being asked. If they refuse to put a price in writing, or give you a vague "it depends" with no further explanation, do not open the door.
4. They Always Try Non-Destructive Entry First
Drilling a lock is expensive for the customer and easy for the locksmith. Some rogue operators go straight to the drill because it lets them charge for a replacement lock on top of the labour.
A skilled locksmith will attempt to pick or bypass your lock first. Drilling is a last resort, used only when a lock has genuinely failed in a way that makes non-destructive entry impossible. If you are standing outside right now, our guide on what to do when you are locked out of the house walks through your options before anyone starts work.
5. They Have a Verifiable Local Address and Phone Number
Search "locksmith near me" and look closely at the results. Many of the top listings are national call centres using local-looking phone numbers and addresses they have never visited. You call what appears to be a Derby or Ipswich number, and someone two hundred miles away dispatches whoever is available, not whoever is qualified.
Check any locksmith's address on Google Maps Street View. Search the company name on Companies House to confirm it is registered and trading, and look for a real local landline rather than just a mobile. If the address does not exist or the phone routes to a call centre, find someone else.
6. Their Reviews Are Genuine and Recent
Do not just count stars. Read the actual reviews.
Fake review patterns are easy to spot once you know them. Generic five-star reviews with no specific detail, no mention of the actual job and no reply from the business are a warning sign, and the MLA has flagged a growing number of locksmith Google profiles carrying fabricated positive reviews.
Genuine reviews mention specifics: the type of job, how long the customer waited, the engineer's name, how the problem was solved. Cross-check reviews on Google, Checkatrade and Trustpilot to build a fuller picture, since each platform shows a different customer base.
7. They Stand Behind Their Work With a Guarantee
Any locksmith who is confident in their work will back it. Not with a vague "we will sort it if something goes wrong", but with a written guarantee that has a clear timeframe and covers both workmanship and parts.
Ask exactly what is covered and for how long, whether the job is a lock repair or a full replacement. A locksmith who cannot tell you what their guarantee covers is a locksmith who has not thought very hard about quality.
Red Flags: How to Spot a Fake Locksmith Before You Call
The most common scam in the UK locksmith industry is bait and switch. A rogue locksmith advertises a call-out from £39 or £49. You call because the price seems reasonable. They arrive, glance at your lock, and announce that something is badly wrong. The price climbs, and by the end customers have been charged anywhere from £400 to, in one case documented by the MLA, £1,800 for a standard lockout.
Watch for these warning signs before and after you call:
- Unrealistically low advertised prices. Nobody can profitably attend a job for £39. If it looks too good to be true, it is. Our breakdown of what locksmiths charge per hour in the UK shows what realistic pricing looks like.
- No clear price before they start. Hesitation or evasion when you ask for a written quote should stop you immediately.
- They go straight to drilling. As covered above, in most cases that is a choice, not a necessity.
- They arrive in an unmarked vehicle with no ID. A professional works from a marked van and carries identification. If neither is present, ask for both before letting them near your door.
- They push for cash-only payment. Cash leaves no trail. Legitimate businesses accept card.
- The call routes to a call centre. Ask directly: "Are you the locksmith who will attend, or will you be sending someone?" If they cannot name the engineer, that tells you everything.
What to Ask a Locksmith Before You Let Them In
Keep this list somewhere easy to find. Five questions. Ask all of them.
- Are you DBS checked, and can I see the certificate when you arrive?
- What is the total cost for this job, including parts and labour, before you start?
- Will you attempt non-destructive entry before considering drilling?
- Can I have the quote in writing before work begins?
- What guarantee do you offer on the work and the parts?
A trustworthy locksmith will answer all five without hesitation, and a good one will often cover them before you ask. If you are locked out right now, our emergency locksmith checklist walks through what to do step by step.
If any question is met with deflection, irritation or a sudden change in the quoted price, end the call.
How to Check If a Locksmith Is Legitimate: Step by Step
Run these checks before you call if you have the time. If it is 2am and you are locked out, use the five questions above instead.
Step 1. Search the company on Google Maps and click through to Street View. Does a real business exist at that address, or is it a residential house, an empty plot or a street that does not exist?
Step 2. Go to Companies House and search the business name. Confirm the company is registered and active, and that the registered address matches what they advertise.
Step 3. Check whether the locksmith belongs to a recognised trade association. If they claim MLA approval, you can verify the membership directly on the MLA website.
Step 4. Read reviews on more than one platform. Google, Checkatrade and Trustpilot each show a different customer base, so look for consistent, recent reviews with specific detail across all of them.
Step 5. Call them and ask the five questions from the section above. The quality of the answers will tell you what you need to know.
Checking a Locksmith’s Availability for Your Area
Do not infer coverage from a list of towns. Contact the provider, give the exact address and fault, and ask whether someone is currently available to take the job.
Whichever city you are in, the same verification steps apply. Check the address, confirm the company on Companies House, and ask whether the engineer attending is actually based nearby rather than dispatched from two counties away.

Why Choosing a Local, Vetted Locksmith Protects You
There is a reason local matters.
A local locksmith has a reputation to protect in the place where they live and work. They cannot disappear after a job goes wrong. Their name and address are real, and when something does go wrong, as it occasionally will in any trade, there is a real person accountable for putting it right.
National networks and call centres offer the opposite. The person sent to your door may never have worked in your area before, the company name might change, and the phone number might be disconnected by tomorrow.
Apply every check in this guide to Kingdom Locksmith and any other provider: verify the company, ask the five questions and judge the answers. For more context, read why a professional locksmith matters for home safety.

Even so, a trustworthy locksmith is not hard to find once you know what to look for: a verifiable address, a written quote before work starts, non-destructive entry as the default, and straight answers on background checks and guarantees. Ask the five questions before you let anyone in.
To check availability, call Kingdom Locksmith or use the online contact page. Give the exact address and job details, then confirm timing, scope and price before booking.
Frequently Asked Questions
Is locksmithing regulated in the UK?
No. Locksmithing in the UK has no government regulation or licensing requirement, and anyone can legally trade as a locksmith without formal training or qualifications. The Master Locksmiths Association runs a voluntary accreditation scheme, but membership is not compulsory, which makes it essential to verify any locksmith before hiring them.
How do I know if a locksmith is legitimate?
Check that they will discuss DBS checks openly, have a verifiable local address, and will provide a written quote before starting work. Confirm the company registration on Companies House and read reviews across more than one platform. A legitimate locksmith answers questions directly and never asks for cash payment upfront.
What is a DBS check and should my locksmith have one?
A DBS (Disclosure and Barring Service) check confirms that a person has no criminal record relevant to working in people's homes. There is no legal requirement for locksmiths to hold one, but any locksmith operating professionally should be able to show you a current certificate. If they refuse or cannot produce one, treat that as a warning sign.
How much should a trustworthy locksmith charge in the UK?
Prices vary with the job, the time of day and your location. A standard lockout typically costs between £100 and £200, and lock replacements start from around £120 depending on the lock type. Be very cautious of any advertised call-out below £60, as that is a common entry point for bait-and-switch scams. Always get a written quote covering the total cost before work starts, and see our full guide on how much a locksmith costs in the UK for detail.
What should I do if I think I have been scammed by a locksmith?
Report the incident to your local Trading Standards office or contact Citizens Advice for guidance, and keep any receipts, messages or photos as evidence.
