SIA Licence Check: How to Verify a Security Guard's Licence
SIA licence check — use the SIA Public Register to verify a security guard's licence, check status, expiry, sectors covered, and renewal options.

An SIA licence check uses the Security Industry Authority's free Public Register to verify whether a security operative holds a valid licence and which sectors it covers. The Public Register is the official tool published by the SIA — the UK's regulator of the private security industry — and it's the only authoritative way to confirm someone's licence status. Employers, venue managers, contractors, and members of the public all use it for the same reason: to confirm that the person doing security work is licensed to do it.
This guide explains how to run an SIA licence check, what each result means, the different licence types you might encounter, and what to do if a check returns an unexpected result. We'll cover the licence categories the SIA issues — Door Supervisor, Security Guard, Close Protection, CCTV Public Space Surveillance, Cash and Valuables in Transit, Vehicle Immobiliser, and Key Holding — plus the difference between front-line and non-front-line licences. We'll also cover renewal, the Approved Contractor Scheme, and how to check your own licence as an operative.
Running a check takes about thirty seconds. The Public Register lets you search by licence number or by the operative's first and last name, optionally filtered by date of birth or postcode. It returns a record showing the licence holder's name, photograph, licence number, status, expiry date, and the sector(s) the licence covers. The information is free to access and updated continuously as the SIA processes new licences and changes to existing ones.
Why does the licence matter so much? Working in licensable security activity without a valid SIA licence is a criminal offence under the Private Security Industry Act 2001. Hiring an unlicensed operative is also an offence. The penalties — fines up to £5,000 and up to six months in prison — are real, and prosecutions happen every year. Doing a quick licence check before deploying staff or hiring contractors protects you legally and operationally. The check costs nothing and takes less time than reading this paragraph.
For operatives, knowing how to run your own licence check is just as important. It lets you confirm your record is accurate, monitor your expiry date, catch any administrative issues early, and produce verification on demand for door staff, CSCS-equivalent industry checks, or new contracts.
Most experienced operatives run the check on themselves at least once a year as part of normal record-keeping, and many bookmark the Public Register for quick access. The Register is also one of the few official UK regulator tools that loads quickly on a mobile phone, which makes it practical to use during pre-shift checks at the door of any licensed venue.
SIA licence check at a glance
What it is: the SIA's free Public Register, the only official tool to verify a UK security operative's licence. Where to find it: the SIA section of GOV.UK. What you can search: licence number, or first and last name plus optional filters. What it returns: name, photograph, licence number, status, expiry date, and the sectors covered. Why it matters: working unlicensed is a criminal offence under the Private Security Industry Act 2001 with fines and possible imprisonment for both the operative and the employer.
How to run an SIA licence check
The check itself is straightforward. Open the SIA Register on GOV.UK, choose whether to search by licence number or by name, and enter the details. Searching by licence number is the most reliable method because it goes directly to a single record. The licence number is a 16-digit string printed on the front of every SIA licence card, and operatives generally know it or have it readable on the card itself when working a shift on the door.
Searching by name returns a list of matches and is useful when you don't have the licence number. Add date of birth or postcode to narrow down common names. Photographs in the record help you confirm you're looking at the right person rather than a similarly-named operative. The Public Register doesn't let you browse all licence holders — you must enter specific search criteria — which is intentional, since the database is meant for verification rather than data scraping for marketing.
Once a record opens, look for the licence status (Active, Suspended, Revoked, Pending, Expired), the expiry date, the sector(s) the licence covers, and the photograph. Active licences within their expiry date are valid for the listed sectors. Anything else means the licence is not currently valid for licensable work. The page also shows whether the operative is associated with an Approved Contractor Scheme (ACS) employer, though that's optional information that not every record displays.
The Register is mobile-friendly. Door staff and venue managers commonly run checks on a phone at the start of a shift if they're working with an operative they don't know. The search loads quickly even on a 4G connection and returns the result in seconds. Some employers maintain their own internal compliance system that imports SIA data via the Register's API, but for one-off or small-scale checks, the public-facing search is more than enough for everyday verification work.

What the SIA Register record shows
16-digit unique identifier printed on the licence card. The number stays with the operative across renewals — same number on the new card after each renewal cycle. Use this number for the most reliable search since it returns exactly one record without ambiguity from common names.
Headshot taken at the time of original application or the most recent renewal. Use this to visually confirm you're looking at the right person, especially when name searches return multiple matches. The photograph also matches what's printed on the physical licence card the operative carries on shift.
Current state of the licence: Active, Suspended, Revoked, Pending, or Expired. Active is the only status that means the operative can lawfully work licensable security activity. Any other status means the operative cannot work, and an employer who deploys them anyway commits an offence under the Private Security Industry Act 2001.
The date the licence becomes invalid unless renewed. Most front-line licences are valid for three years from issue. Operatives must apply for renewal at least eight weeks before expiry to ensure continuous coverage. The expiry date on the Register is authoritative and supersedes anything printed on a physical card if there's a discrepancy.
Which type of licensable activity the licence permits — Door Supervisor, Security Guard, CCTV Public Space Surveillance, etc. An operative may hold multiple sectors on a single licence. The sectors covered determine what work the operative can lawfully do, and an operative working outside the licensed sectors commits an offence regardless of holding any other valid licence.
If the operative is currently employed by an Approved Contractor Scheme (ACS) registered employer, that may be displayed on the record. ACS membership is voluntary for security companies but signals stronger compliance and quality controls. Not every operative working for an ACS employer is necessarily flagged on the Register; absence of the flag doesn't always indicate non-ACS employment.
Understanding the licence status codes
The five common statuses each mean something specific. Active means the licence is valid and the operative can work lawfully in the sectors covered, up to the expiry date. Pending means the operative has applied or renewed but the SIA hasn't completed processing — pending applicants generally cannot work yet, though a few specific transitional rules apply for certain renewal scenarios that the SIA documents on its guidance pages.
Suspended means the licence is temporarily not valid. Suspensions happen for administrative reasons, ongoing investigations, or compliance issues. A suspended operative cannot lawfully work in licensable activity until the suspension is lifted. Revoked is more serious — the licence has been formally withdrawn, often after a serious offence or breach. Revoked operatives cannot work at all, and the revocation typically prevents them from being granted a new licence for a period of years.
Expired simply means the licence has reached its expiry date without being renewed. Expired operatives cannot lawfully work in licensable activity. Many expired licences eventually return to Active when the operative completes a renewal application, but until that processing finishes, the operative is treated the same as someone with no licence at all under the regulatory framework.
Employers should treat anything other than Active as a stop-work signal. If a licence shows any non-Active status during a shift, the operative cannot continue working in that role until the issue is resolved. Document the check, communicate the situation, and either redeploy the worker to non-licensable duties or send them home. Continuing to deploy a non-Active licensed operative exposes the employer to criminal liability that no commercial pressure justifies under the regulations.
SIA licence sectors
The most common front-line licence. Permits the holder to work as a door supervisor at licensed premises (pubs, clubs, bars, events). Includes the right to perform Security Guard activities as well, since the Door Supervisor licence covers everything a Security Guard does plus the regulated alcohol-environment work. Most operatives starting in front-line security earn this licence first because it offers the broadest range of work opportunities.
When and why employers run checks
Employers in the UK security industry run SIA licence checks at three predictable points. At hire — every offer of employment in licensable security activity should be conditional on a successful licence check. Confirm Active status, the right sector for the role, and an expiry date that gives reasonable runway before the operative would need to renew. Many employers also keep a copy of the check result in the personnel file as evidence of due diligence.
At deployment — many employers run a fresh check at the start of each shift or each new assignment, especially for casual, agency, or contracted operatives. The check confirms the licence hasn't been suspended or revoked since the last verification. For agency-supplied staff this is often a contractual requirement, with venue managers running the check before letting the operative start work that night. Most agencies provide licence numbers in their booking confirmations precisely so this check can be done quickly.
At renewal — large employers monitor licence expiry dates across their workforce and run reminder checks 60-90 days before each operative's expiry. The reminder gives the operative time to renew before the licence lapses, preventing scheduled work from being disrupted. Smaller employers track expiry dates manually using a spreadsheet or HR system that they update each time a licence is checked or renewed across the workforce.
Beyond these three predictable points, ad-hoc checks happen whenever someone has a question about a specific operative — a complaint, an incident report, a new client requirement, or a routine spot-check at a high-profile event. The Public Register being free and instant means there's no friction barrier to running ad-hoc checks. Many compliance officers run several dozen checks per week as part of their normal workflow without thinking twice about the access cost.

Under the Private Security Industry Act 2001, working in licensable security activity without a valid SIA licence is a criminal offence. So is hiring an unlicensed operative. Penalties include fines up to £5,000 and up to six months in prison. The SIA actively investigates and prosecutes both operatives and employers. A 30-second licence check before the start of a shift protects you and your business from serious legal exposure that no commercial pressure justifies in any context whatsoever.
Renewal — what operatives need to know
SIA front-line licences are valid for three years from the date of issue. The SIA recommends applying to renew at least eight weeks before expiry to allow processing time and any follow-up requests for additional documentation. Renewal applications go through the same online portal as the original application, with a fee that's slightly lower than the new-licence fee. As of 2026, renewal fees run around £190 for most front-line licences; the SIA publishes the current fee schedule on its GOV.UK pages.
Renewal also requires up-to-date training. The SIA periodically updates the qualification requirements for each licence type, and operatives may need to take a top-up course before renewing if their original training pre-dates the most recent qualifications. The SIA notifies licence holders directly when these changes apply, but operatives should also check the current requirements every renewal cycle rather than assuming nothing has changed since the last licence cycle three years ago.
Letting a licence lapse means going through the new-application process rather than the simpler renewal process. That includes the full criminal record check, identity verification, training certificate verification, and the higher fee. It also produces a gap in licensable work eligibility, which may affect employment continuity. Most operatives prioritise renewal well in advance for these reasons. The eight-week recommendation gives a reasonable buffer for processing without rushing the paperwork.
One useful renewal tip: keep your photograph, address, and personal details current on the SIA Register throughout the licence cycle, not just at renewal time. Operatives who move house during a licence period must update the SIA within 28 days under the licence terms. Doing so keeps the Register accurate and avoids hassle when the renewal cycle arrives. The same online portal handles personal details updates and licence renewals together as a single operative account that lasts across multiple licence cycles for the same person.
Running an SIA licence check — checklist
- ✓Open the SIA Register on GOV.UK from your phone or computer.
- ✓Choose to search by licence number (most reliable) or by name.
- ✓Enter the search details and submit. Add postcode or DOB to narrow common names.
- ✓Compare the photograph on the record to the operative in front of you to confirm identity.
- ✓Check the status — Active is the only status that means the operative can work.
- ✓Check the expiry date — confirm it's after today's date and gives reasonable runway.
- ✓Check the sector(s) covered — confirm the licence permits the work the operative will do.
- ✓Document the check (screenshot or recorded result) in the personnel file or shift log.
- ✓Re-check at the start of each new shift or assignment for casual/contracted operatives.
- ✓Set reminders 60-90 days before each operative's licence expiry to prompt renewal action.
The Register is also useful for members of the public who interact with security operatives in their work. If you're a venue patron and the door staff seem unprofessional or behave inappropriately, you can note their licence number from the badge they're required to display visibly and run a check yourself. The Register lets the public verify that someone exercising security powers is properly licensed to do so. Reports of licensing concerns can be filed directly with the SIA, who investigate complaints and act where appropriate to maintain industry standards.
Front-line vs non-front-line licences
SIA distinguishes between front-line and non-front-line licences. Front-line licences cover the operatives actually doing security work — door supervisors, security guards, CCTV operators, close protection officers. Non-front-line licences cover business owners, directors, and managers of security companies who don't physically perform security work themselves but who run the business. Both require background checks, identity verification, and SIA approval, but the training requirements and fees differ between the two categories.
Employers running checks usually need to verify front-line licences. The Public Register shows both, but front-line is the usual case. If you're a venue manager engaging a contractor's owner-director (perhaps for a contract review meeting rather than door work), you might check a non-front-line record instead. The format and information are similar, with the licence type field clearly indicating which category applies for the holder being looked up at any given time.
One quirk: front-line licences are the only ones operatives must display visibly while working. The familiar arm-band-mounted licence card with photograph and licence number is the front-line operative's working display. Non-front-line licence holders generally don't display their licence in the same way because they aren't physically performing the security activity that requires it. They still must hold the licence and must produce it on request from the SIA or police.

SIA licences — quick numbers
Approved Contractor Scheme (ACS)
A voluntary quality-mark scheme run by the SIA for security companies. Companies that meet the SIA's compliance and management standards are awarded ACS status, which signals to clients that the company operates to a higher standard than the legal minimum. Many large clients (major retailers, public-sector contracts, large venues) require ACS membership in their procurement criteria.
Working for an ACS-registered employer often means better pay, better training, and stronger HR practices than non-ACS employers in the same market. The ACS framework requires the employer to demonstrate ongoing compliance with employment law, training delivery, and operational standards that benefit the workforce as well as the clients of the security company.
The SIA Register can show ACS association on individual operative records, but the more direct check is the SIA's separate ACS Register of approved companies. That register lets you confirm whether a security supplier is currently ACS-approved before signing a contract or referring a friend looking for security work to that employer.
ACS-approved companies can opt into additional sector-specific supplements (e.g., for events, retail, or public-sector work). These supplements add deeper standards in the chosen specialty. Clients procuring security in those specialties often look for the relevant ACS supplement as part of their criteria when evaluating bids from competing security suppliers across the marketplace today.
Common licence-check problems and fixes
The most common problem is a name search returning multiple matches and not knowing which is the right person. The fix is to add a postcode or date of birth to narrow the search, or to ask the operative for their licence number directly. Operatives are required to know their licence number and produce it on request, so asking is reasonable. The number takes you directly to a single record without any ambiguity from common names.
The second-most-common problem is finding a record that doesn't match expectations — wrong photograph, wrong sector, or status that's not Active. If the photograph doesn't match the person in front of you, treat it as a serious red flag and refuse deployment until the discrepancy is explained. Wrong sector means the operative isn't licensed for the work being asked of them. Non-Active status means they cannot work at all. Each of these requires escalation to a manager or the SIA before the operative continues working.
The third issue is records that the operative claims should exist but don't appear. Sometimes a freshly-renewed licence hasn't yet been processed and updated on the Public Register. The SIA's processing time has improved over recent years, but small lags still happen. Operatives can usually produce a confirmation email or letter from the SIA showing the licence has been issued, even if the Register hasn't been updated yet. Treat that as interim evidence while you confirm with the SIA directly that the issuance is in fact valid.
