How to start a locksmith business in the UK

A locksmith business runs on skill and trust in roughly equal parts. Work through these steps:

1. 1Training in opening, fitting and uPVC locks, and time working alongside an experienced locksmith if you can get it.
2. 2A DBS check, so you can show customers and trade bodies your record.
3. 3Membership of the Master Locksmiths Association, starting at the entry level.
4. 4A business structure: sole trader or limited company.
5. 5HMRC registration, and a plan for VAT and Making Tax Digital as you grow.
6. 6Insurance: public liability and cover for your tools and van.
7. 7Prices for daytime, night and weekend work, and a way to answer urgent calls at any hour.

No. There's no government licence for locksmiths in the UK, so anyone can trade as one. The Master Locksmiths Association says it was set up in the absence of government licensing, and it runs its own vetting, inspection and qualification scheme instead.

That cuts both ways for a new business. It's easy to start, but customers have heard about rogue locksmiths and will look for proof that you're trained and vetted. Anyone searching how to become a locksmith UK will find plenty of short courses, so stand out with recognised training, a clear DBS check, MLA membership and honest prices quoted before you start.

Most new locksmiths start with a short practical course, then learn on real jobs. The MLA runs its own courses and publishes the prices. Its 5 day beginners course costs £1,812.80 including VAT, or £1,653.15 for members. It combines a 2-day foundation course with one-day modules in basic opening, fitting and uPVC, and you can book the modules separately.

Later, the MLA Qualification is a Level 4 certificate, regulated by Ofqual and certified by ABBE, aimed at experienced locksmiths. It's sat in four modules and priced per module. Passing it is part of the route to MLA Approved Company status.

Plan to specialise as you go. Auto locksmithing, safes, access control and commercial door hardware each need extra training and kit, and each can pay better than domestic lockouts alone.

For most new locksmiths, yes. The MLA has four membership categories:

• Registered membership: the entry level, for people who want to become a locksmith or already trade as one. It needs a standard-level DBS check and two references.
• QML membership (Qualified Master Locksmith): for locksmiths who've passed the MLA Qualification. It also needs a standard DBS check and two references.
• MLA Approved Company: for companies that pass an inspection by the MLA's inspectorate. Members can use the MLA logo and appear on its Find a Locksmith page.
• Affiliate: for suppliers, manufacturers and distributors to the trade.

To become an Approved Company, the MLA says you need at least 2 years' experience and must pass the MLA Qualification within four years of registering. Your company is inspected by an MLA inspector, listed for other members to object to within 21 days and reviewed by the MLA board. The MLA doesn't publish membership fees online, so ask its membership team for the joining pack.

There's no law that says a locksmith must have one, but you're asking customers to let you into their homes and fit the locks that keep them safe. A DBS certificate is the quickest way to show you're trustworthy, and the MLA asks for a standard-level DBS check before you can join.

In England and Wales you can apply for a basic DBS check yourself. It costs £20 and usually takes up to 3 days to process, then a paper certificate is posted to you. The MLA asks for a standard-level check, which is a different level from the basic one, so follow the MLA's joining instructions before you apply. Scotland and Northern Ireland have their own checking services.

Most people starting out as a locksmith begin as a sole trader, because it's the simplest structure to set up and run. You can start trading straight away and you keep the profits after tax. The catch is that a sole trader has unlimited liability: you're personally responsible for all of the business's debts.

A limited company is legally separate from you. GOV.UK explains that company owners are responsible for business debts only up to the value of their investment, but directors take on more paperwork: company records, a confirmation statement, annual accounts and a Corporation Tax return. Registering a company with Companies House costs £100 online, and it's usually done within 24 hours.

GOV.UK also says it's usually easier to move from sole trader to limited company than the other way round. Plenty of trades start as sole traders and talk to an accountant about incorporating once profits grow.

As a sole trader you can start working before you tell HMRC, but you must register for Self Assessment once you earn more than £1,000 in a tax year. The deadline is 5 October after the end of the tax year you started in. HMRC's current page gives 5 October 2026 for the tax year that ended on 5 April 2026, so if you start trading in the 2026 to 2027 tax year, register by 5 October 2027. Register late and you could get a penalty.

Then keep these dates and thresholds in view:

• Making Tax Digital for Income Tax: sole traders with qualifying income over £50,000 should have started from 6 April 2026. The threshold drops to £30,000 from 6 April 2027 and £20,000 from 6 April 2028, so a new business may need digital records and quarterly updates sooner than you'd expect.
• VAT: you must register if your taxable turnover for the last 12 months goes over £90,000, or you expect it to in the next 30 days. You can register earlier if you want to reclaim VAT on the van and tools.
• Records: keep every receipt, invoice and mileage note from the first day. It makes the tax return quicker and the business easier to price.

If you fit locks and door hardware on building sites for a contractor, check the Construction Industry Scheme. It covers construction work including alterations and repairs to buildings, and a registered subcontractor has 20% deducted from payments, or 30% if not registered. Domestic lockouts and lock changes for homeowners aren't affected.

• Public liability insurance: covers damage to a customer's door or property and injury to other people. It isn't a legal requirement, but it's expected, and commercial customers and letting agents will ask for it.
• Tools and van cover: a locksmith's van holds expensive opening tools, key machines and stock, so check the limits on tools left in the van.
• Employers' liability insurance: compulsory from the day you employ someone, with cover of at least £5 million. The Health and Safety Executive sets out the legal requirement.

Simply Business says 10% of locksmiths paid £67.57 or less a year for up to £2 million of public liability cover between January and June 2026. That's the cheapest tenth of its customers, so get your own quotes.

Training and the van are the big costs. These are published prices, checked on 22 October 2026:

Sources: Ford Transit Connect, MLA beginners courses, Simply Business locksmith insurance, GOV.UK basic DBS check and Companies House registration via GOV.UK.

Example only: a sole trader buying the van above new, taking the MLA beginners course as a non-member, with the insurance figure above and a basic DBS check, would spend £26,500.37 before tools, stock and VAT on the van.

Price from your costs and the hours you can bill, then add night and weekend rates that make a 2am callout worth getting out of bed for. Quote the full price on the phone before you set off. Surprise bills are what give the trade a bad name.

Our guide on what to charge as a locksmith works through a daytime rate, out-of-hours rates, fixed prices for lockouts and lock changes, and 2026 market rates.

1. 1Set up a free Google Business Profile. Most lockout customers search on their phone, and Google advises you to keep your profile complete and accurate, respond to reviews and add photos. Use your real business name: adding keywords or towns to the name breaks Google's rules.
2. 2Ask every customer for a review. Reviews that mention a fair price and a fast arrival are what the next locked-out caller looks for.
3. 3Contact letting agents, property managers and landlords. Tenants move out, keys go missing and locks need changing between tenancies.
4. 4Approach local businesses about commercial work: master key systems, fire doors and access control.
5. 5Show your DBS check, training and MLA membership on your website and Google profile.

When you work alone, every call comes in while you're on a job, driving or with a customer. In a 2026 BT survey, 75% of UK adults said they'd give a business three call attempts before giving up on it. A new locksmith doesn't have a name yet, so a missed first call is often a customer you never hear from again.

You have a few options:

• Voicemail. It's free, but many callers won't leave a message and will ring the next number on the list.
• Calling back between jobs. It works when you're quiet, and falls apart in a busy week.
• A family member or a part-time receptionist. Reliable, but it costs wages and only covers set hours.
• An answering service or an AI receptionist that answers in your business name and sends you the details.

Put your own numbers into our missed call calculator to see what missed calls could cost each week. If you'd like a receptionist that takes the call for you, see how Ringzel works as an AI receptionist for locksmiths. Many lockouts happen at night, and our guide to out-of-hours call answering covers how to handle those calls.

To grow a locksmith business, move from one-off lockouts towards work that repeats and pays more: commercial contracts, letting agents, access control, safes and auto locksmithing. Working towards MLA Approved Company status helps with commercial customers who need a vetted supplier.

Taking on your first employee changes your legal duties. Before the first payday:

1. 1Register as an employer with HMRC. You must do it before the first payday, and not more than 2 months before you start paying people, then run payroll through PAYE.
2. 2Get employers' liability insurance from the day they start. The Health and Safety Executive says it's compulsory insurance, required by law. GOV.UK says it must cover at least £5 million, and you can be fined £2,500 for every day you're not properly insured. There are narrow exceptions, such as only employing close family.
3. 3Set up a workplace pension. You must enrol staff aged 22 to State Pension age who earn at least £10,000 a year and normally work in the UK, and pay at least 3% of their qualifying earnings.
4. 4Pay at least the minimum wage. From April 2026 the National Living Wage for workers aged 21 and over is £12.71 an hour.

An apprentice can be a cheaper way to build a team you've trained yourself. In England an apprentice must be paid at least the apprentice rate, which is £8 an hour from April 2026 for apprentices under 19 or in their first year. If you don't pay the apprenticeship levy, which most small firms don't, the government says it pays 100% of the training and assessment cost for apprentices aged 16 to 24, up to the funding band maximum. You must give them time off for training and work alongside experienced staff, so take one on when there's steady work and someone with time to teach. Scotland, Wales and Northern Ireland run their own schemes.
