An SIA licence is a legal requirement for anyone working in the private security industry in the UK. The Security Industry Authority—known as the SIA—is the government body that issues these licences and regulates the sector. Without a valid licence, you can't legally work as a door supervisor, security guard, CCTV operator, or in several other security roles.
Think of it this way: your SIA licence is your professional ID card. It tells employers, venues, and the public that you've been trained, vetted, and approved to do the job. It's laminated, wallet-sized, and carries your photo, licence number, and expiry date. Every front-line security professional you see at a club, shopping centre, or event should be carrying one.
The SIA was established under the Private Security Industry Act 2001, and the licensing scheme became compulsory from 2003 onwards. Before that, the industry had no formal regulation—anyone could work security without checks or training. The SIA licence changed all that, bringing consistency and accountability to a sector that's grown significantly over the past two decades.
If you're doing licensable conduct—basically, front-line security work—you need one. The roles covered include:
If you're in a management role and don't do front-line work yourself, you may need an SIA Approved Contractor Scheme (ACS) accreditation instead—but most operational staff need the standard licence. Volunteers and certain exempt roles (like military or police) have different rules.
There isn't just one SIA licence—there are several, each tied to a specific role. The most common ones you'll encounter:
Door Supervisor Licence — the most popular. It covers venue security and includes first aid training, conflict management, and physical intervention. Many door supervisors also add the CCTV module to get a dual licence, which makes them more employable.
Security Guard Licence — covers static guarding roles. The training is shorter than door supervision and doesn't include physical intervention, so it suits roles like retail security, site guarding, and reception security.
CCTV (Public Space Surveillance) Licence — required if you're monitoring cameras in public spaces. It's worth noting that CCTV in a private shop or office doesn't need this licence—only public-facing surveillance does.
Close Protection Licence — for bodyguard work. This one has higher training requirements and is more expensive to obtain. Most close protection operatives start with a door supervisor licence first.
Before you can apply for an SIA licence, you need to meet several criteria. The SIA isn't just handing these out—there's a genuine vetting process involved.
You must be 18 or over. There's no upper age limit, but you need to be at least 18 to apply.
You must have the right to work in the UK. The SIA checks your identity and immigration status. If you're applying on a limited visa, your licence will only be valid for the duration of your right to work.
You must pass a criminal record check. A basic Disclosure and Barring Service (DBS) check is mandatory. Certain criminal convictions—especially violent ones or those involving dishonesty—will lead to a refusal. Minor or spent convictions don't automatically disqualify you, but the SIA assesses each application individually.
You must complete the required training qualification. This is the big one. You can't just apply—you need a recognised qualification first. More on this below.
The qualifications accepted by the SIA are at Level 2 or Level 3, depending on the role. For a security guard licence, you're looking at a Level 2 Award for Door Supervisors or, more specifically, a Level 2 Award for Security Guards. For door supervision, it's the Level 3 Award for Door Supervisors.
These qualifications are delivered by SIA-approved awarding organisations—bodies like HABC, Highfield, NOCN, and SFJ Awards. You can't just turn up and sit the exam; you need to go through a training provider that's been vetted and approved.
The training itself covers:
The duration varies. A security guard course can typically be completed in about three to four days of intensive training plus an assessment. Door supervisor training takes longer—around 150 guided learning hours—which usually translates to two or three weeks full-time, or longer part-time.
You'll need to pass written assessments and, for door supervisors, a practical physical intervention assessment. Don't skip preparation—the first-time pass rate for some modules hovers around 60-70%, so it's worth taking the revision seriously.
Once you've completed your training and received your qualification certificate, here's the process:
Step 1: Get your qualification certificate. Your training provider sends this directly, usually within a few weeks of completing your course. Don't apply before you have it—the SIA will reject incomplete applications.
Step 2: Create an account on the SIA website. Go to sia.homeoffice.gov.uk and register. The application is done entirely online.
Step 3: Complete the application form. You'll need to provide your personal details, your qualification details, and your identity documents. The SIA accepts passports, biometric residence permits, and other approved ID documents.
Step 4: Pay the fee. As of 2024, the fee is £190 for a three-year licence. This is non-refundable, so make sure you meet the requirements before applying.
Step 5: Undergo the criminal record check. The SIA triggers a DBS check as part of the process. You don't need to apply for this separately—it's built into the application.
Step 6: Wait for a decision. Standard processing takes around 25 working days, though it can be faster. You can track your application online.
The SIA application fee is £190 for a three-year licence—that's the official fee paid directly to the SIA. But that's only part of your total cost.
Training courses are additional. A security guard course from a reputable provider typically costs between £200 and £400. Door supervisor training, being longer and more involved, usually runs between £600 and £1,200 depending on the provider, location, and whether it includes resits.
So realistically, getting your SIA licence from scratch will cost you somewhere between £400 and £1,500 all in. Some employers—particularly larger security contractors—will fund the training for candidates they want to hire. It's worth asking before you sign up for a course.
First aid certificates, if not included in your training, add another £80–£150. And if you're doing close protection, expect to pay significantly more—that training alone can run to £3,000 or beyond.
SIA licences are valid for three years. You can apply to renew up to six months before your licence expires—and you should, because if it lapses you'll need to reapply from scratch, which means the full fee again and potentially refresher training.
Renewal costs the same: £190. The process is similar to the initial application—online, through the SIA portal. The SIA will run another DBS check, so any new convictions in the three-year period will be reviewed.
You don't automatically need to redo your training qualification when renewing, unless your qualification has a specific expiry (some first aid certs need refreshing, for example). Check with your qualification awarding body to be sure.
This one's straightforward: don't do it. Working in a licensable role without a valid SIA licence is a criminal offence under the Private Security Industry Act 2001. You could face an unlimited fine or up to five years in prison. Employers who knowingly hire unlicensed staff face similar penalties.
The SIA carries out regular inspections and enforcement operations. Venues—especially nightclubs and large events—get checked. If you're found working without a licence, both you and your employer face serious consequences.
There's no grace period or informal arrangement that makes it acceptable to work without one. If your licence has expired or you're waiting for your first application to come through, you can't legally work front-line security in the meantime.
A few things can help speed up the process or improve your chances of approval:
Choose an accredited training provider carefully. Not all providers are equal—some have better pass rates, more experienced trainers, and better-organised assessments. Read reviews, ask about pass rates, and check they're on the SIA's approved list before booking.
Get your paperwork ready before applying. Having your identity documents scanned and ready, your qualification certificate to hand, and your right-to-work documents in order means you can submit a clean, complete application the first time.
Don't rush the training. Even if a provider offers an unusually fast course, the guided learning hours are there for a reason. Rushing through the material increases your chance of failing assessments, which wastes time and money.
Be honest on your application. The DBS check will surface convictions—trying to hide them makes things worse. The SIA assesses applications fairly, and a minor conviction doesn't necessarily mean a refusal.
If you've moved to the UK from abroad and want to work in security, your overseas security experience counts for something—but your foreign licence doesn't. You'll need a UK SIA licence regardless of what you held in your home country.
The right to work check is particularly important for international applicants. You'll need to demonstrate your immigration status clearly. If you're on a work visa with a specific end date, your licence will mirror that expiry rather than the standard three years.
Language isn't a formal requirement listed by the SIA, but training courses are delivered in English, and you'll need to pass written assessments in English. Practical communication skills are also assessed for some modules. If English isn't your first language, factoring in some preparation time before starting the course is sensible.
Several training providers do offer support for ESOL learners, so it's worth asking when you're shopping around for courses.
Getting your SIA licence opens doors—literally and professionally. The UK security industry employs around 350,000 people, and demand for licensed professionals is steady. Entry-level security guard roles typically pay between £10 and £13 per hour; door supervisors can earn £12 to £18 or more, especially in London or at busy venues.
From there, career paths branch in a few directions. Experienced operatives often move into supervisory or management roles, where you're coordinating teams rather than doing front-line work yourself. Close protection is a lucrative specialty, though it requires significant additional training and experience. Some people use their SIA licence as a stepping stone into the police service or other protective roles.
The licence you earn stays with you—it belongs to you, not your employer. That means if you change jobs, you take it with you. In a sector where many workers are on contracts or move between employers, that portability matters.
No. You cannot legally work in a licensable security role while your application is pending. Working without a valid SIA licence is a criminal offence, regardless of whether you've applied or are awaiting a decision. You must have the physical licence in hand before you start work.
The SIA aims to process applications within 25 working days of receiving a complete application. But that clock only starts once you have your training qualification—which itself takes several days to weeks to complete. Factor in total time from starting training to receiving your licence: typically six to ten weeks minimum.
Not automatically, no. The SIA looks at each application individually. Minor or spent convictions don't always lead to a refusal. However, convictions for violence, dishonesty, or offences related to public safety are viewed seriously and can result in rejection. Be honest on your application—hiding convictions is worse than disclosing them.
Both are SIA licences, but they cover different roles and training. A security guard licence suits static guarding—protecting premises or assets. A door supervisor licence covers venue security and includes additional training in first aid and physical intervention. Door supervisor training is longer and more expensive, but the licence is more versatile and often pays better.
Yes. The SIA licence covers England, Wales, and Scotland. Scotland has its own regulatory body—the Scottish Government oversees some aspects—but the SIA licence is the required document for front-line security work across Great Britain. Northern Ireland has a separate licensing authority: the Security Industry Authority (Northern Ireland) operates under different legislation.
If your licence expires, you can no longer legally work in a licensable role. You'll need to apply for a new licence—paying the full £190 fee again—and the SIA will run another criminal record check. You may also need refresher training depending on how long your licence has lapsed. Don't let it expire: renew up to six months before the expiry date.
No. The SIA licence is a UK-specific document. If you work in other countries, you'll need to meet their local licensing requirements. The training and experience you've gained is valuable, but the licence itself has no legal standing outside of Great Britain.
If security work is what you want to do—yes, absolutely. The licence is the entry ticket to a regulated, growing industry. Without it, you're locked out of front-line work legally. With it, you have credibility, employability, and a foundation to build a career on.
The upfront cost—training plus the application fee—is real, but it's not unreasonable compared to what many other vocational qualifications cost. And unlike a lot of professional certifications, the SIA licence leads directly to paid employment fairly quickly. Many people are working within weeks of completing their training.
There's also a practical upside: because the industry is regulated, wages have improved over the past decade. Employers can't just hire anyone who turns up anymore—they need licensed staff, which gives you bargaining power.
If you're serious about a career in security, start by researching SIA-approved training providers in your area. Compare prices, check their pass rates, and look for providers that offer support beyond just sitting you in a classroom. The training is only the beginning—but getting it right sets you up for everything that follows.
