Locksmith insurance: key facts
- There is no general licensing scheme for locksmiths in the UK, and public liability insurance is not a legal requirement for a sole trader.
- Employers' liability is a legal requirement once you employ anyone, with at least £5 million of cover. Fines can reach £2,500 a day.
- Locksmith insurance for a sole trader costs roughly £100 to £250 a year for public liability only, including 12% Insurance Premium Tax (rough guide figures).
- Products and completed works cover matters because a lock you fitted can fail months after the job.
- Stolen contents after a burglary are not automatically covered just because your lock failed. Many policies limit or exclude theft losses.
- Professional indemnity covers claims that your security advice cost a client money, such as locks that don't meet their home insurer's requirements.
- The Master Locksmiths Association is a voluntary trade body whose vetting is widely recognised by customers and agencies.
What does locksmith insurance cover?
Locksmith insurance is usually a package: public liability and products and completed works at its core, plus tools and stock, key holding, professional indemnity if you advise, and employers' liability once you have staff.
| Cover | What it protects | Who needs it |
|---|---|---|
| Public liability | Injury to others or damage to their property, such as a cracked uPVC frame or a customer tripping over your tools. | Every locksmith. This is the base of any policy. |
| Products and completed works | Injury or damage caused by a lock or fitting after you've finished the job. | Every locksmith who fits, repairs or supplies locks. |
| Professional indemnity | Claims that your security advice, survey or specification caused a financial loss. | Locksmiths who survey, design master key systems or advise on lock standards. |
| Key holding and loss of keys | Changing locks and recutting keys if client keys or key records you hold are lost or stolen. | Anyone holding client keys, key codes or master key records. |
| Tools and equipment | Picks, decoders, drills, key cutting machines and programmers if stolen or damaged. | Every mobile locksmith. |
| Stock in the van | Locks, cylinders, key blanks and hardware carried to jobs. | Anyone carrying more than a few hundred pounds of stock. |
| Employers' liability | Claims from staff hurt or made ill at work. | A legal requirement once you employ anyone, including part-time help. |
| Personal accident | A payment if an injury or assault stops you working. | Sole traders, especially on night call-outs alone. |
| Business van cover | Driving to jobs, via your motor insurer. | Anyone who drives for work. Needs business use. |
Locksmith public liability insurance: damage when gaining entry
Locksmith public liability insurance pays compensation and legal costs if your work injures someone or damages their property. For locksmiths the main risk is damage caused when gaining entry, especially when non-destructive methods fail.
Most lockouts start with non-destructive entry: picking, bypass or letterbox tools. When that fails, you drill or snap the cylinder, and the customer accepts the lock will be replaced. Claims come when damage goes further:
- uPVC and composite doors. A slipped drill or forced multipoint mechanism can crack a frame or ruin a gearbox. A new composite door can cost four figures.
- Glazing. A cracked double-glazed panel while working a letterbox tool.
- Period doors. Split timber or original hardware that can't easily be replaced.
Explain the likely method and possible damage, get the customer's agreement by text or in writing before you drill, and take before-and-after photos.
If a burglary follows a lock you fitted: how locksmith insurance responds
If a burglar gets in because a lock you fitted failed, or a door was left insecure, the customer may claim against you. Liability cover usually responds to physical damage and injury, but stolen contents are often limited or excluded.
| Scenario | Cover that may respond | Typical problem |
|---|---|---|
| A defective lock you fitted fails | Products and completed works | Theft following failure of security is often excluded; some locksmith policies add it back with its own limit. |
| You left a door insecure | Public liability | Insurers may argue the burglar, not you, caused the loss. |
| Your recommended lock didn't meet the home insurer's standard | Professional indemnity | Public liability won't pay a purely financial loss. |
| Replacing your own faulty work | Usually none | A standard exclusion. |
Ask the broker: "If a burglar gets in because of a lock I fitted, are the customer's stolen contents covered, and up to what limit?"
Is locksmith insurance a legal requirement?
No law makes a sole-trader locksmith buy public liability insurance, and there is no general licensing scheme for locksmiths in the UK. Employers' liability insurance is a legal requirement once you employ anyone, with at least £5 million of cover, and employers can be fined up to £2,500 for every day without it.
In practice, working uninsured is hard:
- Agencies ask for it. Letting agents, housing associations, facilities managers and lockout networks commonly want proof of £2 million or £5 million of public liability.
- Customers check. People locked out at night are wary of rogue traders.
- Liability is personal. Uninsured, a sole trader pays any compensation from their own money.
Employers' liability applies in England, Scotland and Wales under the Employers' Liability (Compulsory Insurance) Act 1969; Northern Ireland has its own equivalent rules.
How much does locksmith insurance cost?
Locksmith insurance for a sole trader costs roughly £100 to £250 a year for public liability only, including 12% Insurance Premium Tax. Adding tools, stock and professional indemnity typically brings it to £220 to £550. These are rough guide figures only.
| Typical set-up | Rough guide price per year |
|---|---|
| Sole trader, public liability only | £100 to £250 |
| Sole trader adding tools, stock and professional indemnity | £220 to £550 |
| Locksmith business with staff (adds employers' liability) | £550 to £1,300 |
What moves the price:
- The work you do. Domestic lock changes are rated differently from access control, auto work or safe engineering.
- Your limits for public liability and professional indemnity.
- Value of tools and stock, and where they're kept overnight.
- Key holding for clients.
- Staff, turnover and claims history.
Locksmith professional indemnity: security advice and surveys
Locksmith professional indemnity covers claims that your advice, survey or specification was negligent and caused a client a financial loss, for example recommending locks that don't meet their home insurance requirements.
Many home insurance policies require external doors to have locks meeting a named standard, often a five-lever mortice lock to BS 3621, or on uPVC and composite doors an anti-snap cylinder rated to a standard such as TS 007 3-star or Sold Secure Diamond. If you call a lock "insurance approved" and it isn't, the customer's burglary claim may be cut, and they may come to you. Other risks:
- A shop security survey that misses a weak point later used in a break-in.
- A flawed master key system that forces the client to re-key the building.
- Access control that doesn't meet fire escape needs and must be replaced.
If you only do lockouts and like-for-like changes, PI matters less; if you survey or specify, ask for it.
What to check before you buy mobile locksmith insurance
Before you buy mobile locksmith insurance, check how the policy treats theft after a lock fails, entry damage, the key holding limit and the overnight van conditions on your tools.
| Check | Why it matters |
|---|---|
| Theft following failure of security | Many policies limit or exclude a customer's stolen contents. Ask about an extension. |
| Damage during entry | Some policies exclude damage to the door you were working on. |
| Products and completed works | Make sure it's included at the same limit as public liability. |
| Overnight van conditions | Theft from an unattended van overnight is often excluded unless tools are removed or the van has extra security. |
| Key holding insurance for locksmiths | A low limit won't cover re-keying a master key system. Insurers often require keys to be coded, not labelled with addresses. |
| Auto and safe work | Often excluded unless declared. |
| Excess | Can be higher for theft or entry damage. |
Rules, vetting and good practice for UK locksmiths
There is no general licence needed to work as a locksmith in the UK. The Master Locksmiths Association is a voluntary trade body that vets members, and DBS checks are often requested by customers and agencies but are not a legal requirement.
Checking the person is entitled to entry
Letting the wrong person in is one of the trade's biggest risks. Before opening a home or car, ask for proof of residence or ownership, such as ID matching a utility bill, tenancy agreement or logbook (V5C), and record it. With tenants and landlords, check who is entitled to enter: a landlord can't usually just change the locks on a tenant still living there. If in doubt, don't open the door. Insurers may dispute a claim if you didn't take reasonable steps.
Consumer law
Under the Consumer Rights Act 2015, services to consumers must be carried out with reasonable care and skill, and locks you supply must be of satisfactory quality. Give a clear price or call-out fee before you start.
Auto, safe and night work
Car entry can damage paintwork, seals and electronics, and safe opening can damage contents; declare both. Night lockouts mean working alone, so tell someone where you're going; personal accident cover helps if an injury stops you working.
Common locksmith insurance claims
The most common locksmith insurance claims involve damage to doors and frames during entry, locks that fail after fitting, lost client keys and tools stolen from vans.
- A composite door cracks while you drill a snapped cylinder.
- A new nightlatch jams and a customer is hurt climbing out of a window, a products claim.
- A shop is burgled after a lock change and the owner blames your fitting.
- A home insurer refuses a burglary claim because your recommended locks weren't to standard, a PI claim.
- Your van is broken into and picks, key machine and stock are taken.
- Master keys are lost and the client claims for re-keying.
Starting a locksmith business: checklist
To start a locksmith business in the UK, get trained, sort your vetting, arrange locksmith tools insurance and public liability before your first job, and add employers' liability before you hire.
- Register as self-employed with HMRC, or set up a limited company.
- Get trained, especially in non-destructive entry.
- Get vetted: a basic DBS check and, when eligible, MLA membership.
- Get insured: public liability with products cover, tools and stock, key cover, and PI if you'll advise.
- Sort your van: business use on your motor policy and extra security.
- Write an entry procedure for checking proof of residence or ownership.
- Add employers' liability before you take on any help.
Locksmith insurance: use a broker or buy online?
Buying online can suit a sole trader doing simple domestic lock changes. A broker helps if you do auto or safe work, hold keys, survey or advise, or want cover for theft after a lock fails.
Quick-quote sites often treat locksmiths like general handymen, which can leave entry damage or key holding excluded. A broker who arranges cover for locksmiths can compare insurers and explain the theft and products wording. For every type of cover, see our small business insurance guide.
