Locksmiths install, repair and open locks for residential, commercial and automotive clients, and many work as self-employed mobile locksmiths offering emergency call-out services. There is no single mandatory licence to practise, though Master Locksmiths Association (MLA) accreditation is the recognised industry standard. This guide shows exactly what locksmiths take home after income tax, National Insurance and Class 4 self-employed NI for the 2026/27 tax year.
Figures are indicative market rates; self-employed figures are profit after business costs.

Self-employed locksmiths pay Income Tax and Class 4 National Insurance on profits (call-out fees minus allowable expenses) via Self Assessment. Class 4 NI is charged at 6% on profits between £12,570 and £50,270, and 2% above that.
Allowable expenses typically include van running costs, fuel, tools, key-cutting and programming equipment, public liability insurance and marketing/advertising. Capital allowances can be claimed on major tool and equipment purchases.
| Annual Profit | Income Tax | Class 4 NI | Net/yr |
|---|---|---|---|
| £30,000 | -£3,486 | -£1,046 | £25,468 |

| £55,000 | -£9,432 | -£2,357 | £43,211 |
There is no single mandatory licence to practise as a locksmith in the UK, but Master Locksmiths Association (MLA) membership -- requiring assessed competency and insurance -- is widely regarded as the industry standard and is often required by insurers and letting agents.
Locksmiths offering 24-hour emergency lock-out services command significantly higher call-out fees for night, weekend and Bank Holiday work, though this must be weighed against unsociable hours and unpredictable demand.
Automotive key programming and transponder key work requires specialist, often expensive diagnostic equipment and manufacturer-specific training, but commands premium rates over standard residential lock work.
Employed locksmiths working for a security company receive a stable salary, company van and workplace pension, while self-employed mobile locksmiths keep all call-out income after business costs but bear the full cost of van, tools, insurance and no employer pension.
