The Complete Guide to Getting an SIA Security Guard Licence

Picture the moment your SIA application status changes from “in progress” to “granted.” For most applicants, that single screen refresh is the difference between waiting tables and starting a career that pays for site work the day the licence lands. If you’re weighing up a move into security guarding, that moment is closer than you might think, but only if you get the sequence right. Miss a step and you could be looking at weeks of delay over something as small as a mismatched address.

This guide walks you through exactly what an SIA Security Guard Licence involves:

• Who needs one
• What training comes first
• What it costs 
• How the application plays out once you hit submit

The Security Industry Authority (SIA) is the body that regulates England, Wales and Scotland’s private security industry on behalf of the Home Office. If you’re going to work as a security guard protecting premises, property, or people against theft, damage, unauthorised access, or disorder under a contract for services, you need an SIA security guard licence before you start. It’s not a formality. It’s proof that you’ve cleared identity checks, criminal record checks and a recognised training standard.

Once granted, the licence runs for three years. After that, it needs renewing and as of 2025, renewal comes with a training requirement that didn’t exist a few years ago. More on that shortly.

You’ll need a licence if your work involves any of the following:

• Guarding premises or property against damage or unauthorised access
• Preventing theft or the dishonest removal of goods
• Providing a visible security presence to deter disorderly behaviour
• Operating CCTV for security purposes

Here’s where a lot of people get caught out. If you’re employed directly by the company whose premises you’re protecting, say, a supermarket hires you to guard its own store, you typically don’t need an SIA licence for that role. It’s the contract-for-services model, where a security company supplies your labour to a third party, that triggers the licensing requirement.

There are two exceptions to the in-house rule and they apply no matter who employs you: door supervision at licensed premises and vehicle immobilising (Northern Ireland only). If either applies to you, in-house status won’t exempt you.

We’ve seen applicants assume the in-house exemption covers CCTV monitoring simply because they’re on the client’s payroll; it doesn’t always and getting that wrong before you start work can mean an unlicensed activity finding you rather than the other way round. If you’re unsure which side of the line your role sits on. Check with your employer directly rather than guessing.

Before training even enters the picture, you need to meet the SIA’s baseline criteria for an SIA security guard licence:

This is where most delays start, not because the training is hard, but because the order matters and people get it backwards.

Since 2021, you’ve needed a valid Emergency First Aid at Work (EFAW) qualification or an accepted equivalent before you can even enrol on the licence-linked security guard course. Accepted equivalents include:

• Emergency First Aid at Work (EFAW)
• First Aid at Work (FAW)
• First Person on Scene (FPOS)
• First Response Emergency Care (FREC)

Your first aid certificate needs at least 12 months left on it from the start of your licence-linked training, so timing this course correctly matters as much as passing it. K4 Training’s First Aid at Work Course (3 Days) and FREC 3 (First Responder Emergency Care) are both accepted routes into the next stage, so check with your provider which one fits your schedule.

Once your first aid certificate is in hand, you move on to the Level 2 Award for Security Officers in the Private Security Industry, the qualification the SIA actually links to the licence. A few practical details:

• Duration: A minimum of 29 contact hours, typically delivered over 4 days
• Content: Three units, four credits, covering the full range of competences the SIA sets for security guards
• Assessment: Multiple-choice tests plus practical assessment
• Cost: Generally £250–£300

Pass this and you’re qualified to work in unlicensed premises such as schools, offices, warehouses, construction sites, retail units and residential blocks among them. K4 Training’s Security Guarding Course covers this qualification end to end.

If your work will also involve monitoring CCTV for security purposes, that’s a separate licensable activity worth planning for alongside your guard training. K4 Training’s SIA CCTV Operator Course covers it.

• Choose the Right Licence Type

Static guarding, patrol and corporate or retail security roles need a Security Guard licence. Licensed premises, events and entry-control work need a Door Supervisor licence instead. Pick based on the work you actually want, not whichever course is cheaper or starts sooner.

• Gather Your Documents

• Photo ID (passport or driving licence)
• Proof of address, with names and formats matching your ID exactly
• Your licence-linked training certificate
• Your EFAW certificate
• Name-change documents, if applicable
• Right-to-work evidence, if requested

• Nail Your 5-Year Address History

The SIA uses this to run identity and criminal record checks and it needs to be gap-free. Spelling inconsistencies across documents, missing postcodes, or unexplained gaps are among the most common reasons applications stall. Think of this section less as a formality and more as the foundation the rest of your application is built on. Get it wrong and everything downstream slows down, however clean the rest of your paperwork is.

• Apply Online

Applications go through your SIA online account via the official GOV.UK service.

• Complete Identity Verification

Most applicants get a “next steps” message directing them to a participating Post Office with their ID and proof of address, where a photo is also taken.

• Let the SIA Run Its Checks

Identity, criminal record and right-to-work checks all happen at this stage. If you’ve spent six continuous months or more outside the UK in the last five years, you’ll also need evidence of an overseas criminal record check; factor this in early, since it typically extends processing time.

Official GOV.UK guidance confirms it costs £204 to apply for one licence, with that figure taking effect from 1 April 2026 after the temporary £20 rebate the SIA had been funding from historic reserves came to an end. Processing itself typically runs to around 25 working days, though the SIA’s own Decision Timescale Indicator gives the most current estimate for your specific case.

Two things worth flagging. First, the application fee is non-refundable; an unsuccessful application doesn’t come with your money back, which is another reason getting your address history and documents right the first time pays for itself. Second, if you’re applying for an additional licence in a different sector, CCTV alongside guarding, say, a 50% discount can bring that second fee down to £102, though recent SIA changes mean this only applies if both applications are submitted together, on the same form, on the same day. Apply separately later and you may lose the discount entirely, so if you know you’ll want both licences, it’s worth applying for them in one go.

If you already hold a licence, this is the part that’s most likely to catch you out. From 1 April 2025, security guards and door supervisors must complete mandatory refresher training before they can renew a genuine shift from the “recommended” status that training previously held. The SIA introduced the requirement to keep safety-critical skills current, with the refresher content covering search procedures, safeguarding vulnerable individuals and recognising terror threats and spiking risks.

If your original qualification predates April 2021, you’ll need this training regardless of when your current licence expires. It’s not optional and because a valid first aid certificate is also required before you can start the refresher course, it’s worth building the same lead time into renewal planning that first-time applicants build into their initial application.

Already hold a Door Supervisor licence and want to move into guarding instead? You can complete the security guard refresher training and switch licence types directly, without starting the whole process from scratch. K4 Training’s Full SIA Door Supervisor and SIA Door Supervisor Refresher + First Aid courses cover both the initial qualification and this switch route.

• April 2021 — EFAW became a prerequisite for security guard training
• April 2025 — Refresher training became mandatory for licence renewal
• April 2026 — The application fee rose to £204 as the temporary rebate ended

Requirements shift more often than most people expect for a regulated industry, so it’s worth checking current GOV.UK guidance before booking training or submitting an application, rather than relying on older online sources.
