Security work is one of those industries where the line between employment and self-employment gets blurry fast. You might be doing shifts through a security company one week and contracted directly to a venue the next. You might hold your SIA licence and work for yourself, picking up contracts across multiple clients. Or you might be on a regular PAYE contract with one employer but taking on private work at weekends.
The tax rules don’t change depending on how busy things get or how informal the arrangement feels. HMRC expects accurate records and timely returns regardless of how many plates you’re spinning.
At Hayes Chartered Certified Accountants and Tax Consultants, we work with security professionals across London and the UK — door supervisors, CCTV operators, event security, close protection officers, and mobile patrol workers. We understand the working patterns of this industry and know how to handle the tax side of it properly.
This is often the first conversation we have with security clients. The security industry has a high proportion of people working in arrangements where employment status isn’t entirely clear — to the worker or, sometimes, to the company they’re contracting through.
If you’re on a regular PAYE contract through a licensed security company, your tax is handled by your employer. But many security professionals work on a self-employed basis — invoicing clients directly, covering multiple venues or events, and managing their own books.
Getting employment status wrong has consequences in both directions. If you should be employed but are treated as self-employed, you could be missing out on employment rights and your employer could face unpaid NICs liability. If you’re genuinely self-employed but haven’t registered as such, you’ll have untaxed income sitting on your record.
We assess the actual working arrangement and confirm the correct position — not the one that looks most convenient on paper.
If you’re genuinely self-employed in the security industry, your obligations include:
In London especially, self-employed door supervisors and event security workers can earn well during busy periods — but without setting money aside as they go, the January tax bill lands hard.
Security workers have a range of legitimate expenses that can reduce their taxable profit. These commonly include:
A direct cost of being able to work
Clothing that is distinctively work-related and not suitable for everyday wear
Required or used in the course of security work
For self-employed operators
Between different venues or clients (not a regular commute to a single fixed site)
Where genuinely used for work purposes Accountancy fees
Security workers have a range of legitimate expenses that can reduce their taxable profit. These commonly include:
Many security professionals work across several companies at once — particularly in London, where demand for event and venue security can be high. This is entirely legal and common. But it does require careful administration.
Each company that employs you on a PAYE basis will issue its own P60 and will have applied a tax code. When you have multiple PAYE employers, the tax code applied by secondary employers is often BR (basic rate on all earnings) or higher — which can result in overpaying or underpaying tax overall.
Filing a Self Assessment return allows us to reconcile all income sources, apply the correct Personal Allowance and band calculations, and recover any tax overpaid — or plan for any underpaid amount before it becomes a problem.
Close protection officers and specialist security professionals often work at higher income levels and in more complex contractual arrangements — sometimes including overseas work, company structures, and retainer agreements.
Overseas income from security work is generally taxable in the UK if you’re UK tax resident. Contract structures — sole trader vs limited company — have different tax implications at different income levels. We advise on the right structure for your situation.
Whether you’re a door supervisor covering London venues, a self-employed security contractor, or a close protection professional with complex income arrangements, we’re equipped to handle it.

It depends on the arrangement. Most agency workers are employed on a PAYE basis, but some operate as self-employed contractors. We confirm your status based on the actual working arrangement, not just how the paperwork describes it.
Yes. The SIA licence is a professional requirement — without it, you cannot legally work in the sector. The renewal fee is an allowable business expense for self-employed security professionals.
Yes, if your self-employed income from security work exceeds the £1,000 trading allowance. The income needs to be declared on a Self Assessment return alongside your employment income.
Cash income is still taxable income and must be declared. Keeping records of cash payments — amounts, dates, clients — is important both for your own records and to avoid any HMRC challenges later.
HMRC can and does identify undeclared income. Voluntary disclosure before HMRC contacts you typically results in lower penalties. We help clients get up to date and manage HMRC communication properly.
