Lost Your SIA Security Licence? Here's Exactly What to Do 2026 July

Discovering that you have a lost security licence is one of the most stressful situations a working SIA-licensed guard can face. Your licence is not just a card — it is your legal authorisation to work in the UK private security industry, and without it, you cannot legally perform licensable roles such as door supervision, CCTV operation, or close protection. The Security Industry Authority issues each licence with a unique reference number, and that number is what employers, clients, and enforcement officers use to verify that you are permitted to work. Losing it can feel like losing your livelihood.

The good news is that the SIA has a clear process for replacing a lost, stolen, or damaged licence, and most guards can obtain a replacement card without losing their authorisation to work — provided they act quickly and follow the correct steps. This guide walks you through every stage of the process, from the moment you realise your licence is missing right through to receiving your new card in the post. We cover how to report the loss, how to apply for a replacement, what it costs, and how long you can expect to wait.

It is worth being clear about one thing from the outset: losing your physical licence card does not automatically mean your licence has been revoked. Your licence record exists in the SIA database and is tied to your identity and registration number, not to the plastic card in your wallet. However, you must not continue working in a licensable role without being able to produce your licence on request. The SIA has enforcement officers who conduct spot checks on venues and worksites, and being unable to show a valid licence can result in a fixed penalty notice or prosecution.

If your licence was stolen rather than simply misplaced, the process has an additional step: you should report the theft to the police and obtain a crime reference number before contacting the SIA. This is important both for your own protection and because it creates an official record that your licence may be in the hands of someone who could attempt to use it fraudulently. Licence fraud is taken extremely seriously by the SIA, and having a crime reference number demonstrates that you acted responsibly the moment you became aware of the situation.

Many guards worry about what happens to their employment during the replacement period. The answer depends partly on your employer, partly on whether you have a copy of your licence number, and partly on how quickly you initiate the replacement process. Some employers will allow you to continue in a non-licensable support role while your replacement is processed, but this is at the employer's discretion.

It is essential to inform your employer immediately rather than hoping the card turns up. Transparency protects both you and your employer from regulatory risk. Just as understanding your rights around a lost security license and pay during gaps in work is important, so is knowing the replacement timeline.

Throughout this article we will also cover some of the less obvious scenarios — what to do if your licence is due for renewal at the same time as the replacement, how to handle the situation if you work across multiple roles requiring different licence types, and what to do if the SIA replacement process takes longer than expected. We will look at the costs involved, how to track your application, and what documentation you will need to gather before you can submit your replacement request online through the SIA's licensing portal.

Whether you have lost your licence today and are in a panic, or you are reading this as a precaution so you know what to do if it ever happens, this guide gives you everything you need. Take a breath — this is a solvable problem, and the SIA replacement process, while bureaucratic, is designed to protect legitimate licence holders like you.

One of the most pressing questions for any guard who has lost their SIA licence is whether they can legally continue working while waiting for the replacement card. The short answer is nuanced: your licence itself — your authorisation to work — is still valid and exists in the SIA database. It has not been cancelled simply because the physical card is missing. However, the SIA Code of Practice and the Private Security Industry Act 2001 both require licence holders to produce their licence on request, which creates a practical problem if you cannot show the card.

The safest approach is to treat the period between losing your card and receiving its replacement as a period of potential risk. If an SIA enforcement officer visits your worksite and you cannot produce your licence, you may face a fixed penalty notice even if your licence is technically valid.

Enforcement officers have the ability to verify licence status on their systems, and many will do so — but this is at their discretion. The penalty for failing to produce a licence on request is separate from the penalty for working without a valid licence, but both carry consequences that are not worth risking.

Some security companies have established protocols for handling the period when a guard's card is temporarily unavailable. These protocols often involve keeping the guard on non-public-facing duties — administrative work, control room monitoring, or vehicle patrol — where the likelihood of being asked to produce a licence by a member of the public or enforcement officer is lower. This is not a guaranteed legal shield, but it is a pragmatic approach that responsible employers use to balance operational need with regulatory compliance.

It is also worth knowing that the SIA's public licence-checking tool, available at their website, shows the status of any licence by surname and licence number. If you know your licence number — check old payslips, employer records, or any previous email correspondence from the SIA — you can look it up yourself and share a screenshot with your employer as a form of interim verification. This does not replace your obligation to carry the card, but it can give an employer and client some reassurance during the replacement period.

Your licence number is also printed on your CRB or DBS certificate and may appear on your training certificates from your SIA-approved training provider. If you completed your Door Supervisor or Security Guard course relatively recently, contact the training company and ask if they retain a copy of your licence number on file. Many do, particularly if they assisted you with your original licence application. Having this number is invaluable because it allows you and your employer to verify your active status while the physical card is in transit.

Guards who work for multiple employers face additional complications, since each employer will need to be informed of the situation. In the UK, it is not uncommon for guards to work on a self-employed or agency basis for two or three different clients simultaneously. Each of these clients has their own compliance obligations under the Private Security Industry Act, and each will want to know that the guards deployed on their sites hold valid licences. Proactive communication with all employers simultaneously is essential — do not wait to hear whether your replacement card has been approved before informing secondary employers.

Finally, understand that the replacement process is entirely separate from a licence renewal. If your licence is also approaching its expiry date — within six months — you should consider whether a full renewal application might be more appropriate than a replacement, since a renewal will issue you a new card with a new three-year validity period and may be a better use of the £25-plus renewal fee. We cover this distinction in detail in the renewal versus replacement section later in this article.

If your SIA licence was stolen rather than simply lost, you face an additional layer of risk that deserves serious attention. A stolen licence card contains your full name, photograph, and a unique licence reference number. In the wrong hands, this could potentially be used by an unqualified individual to misrepresent themselves as a licensed security professional — a form of identity fraud that the SIA takes extremely seriously. Understanding how the system works can help you protect yourself and others.

The first priority after discovering your licence has been stolen is to call 101 or visit your local police station to report it as a stolen document. Online crime reporting tools can also be used if the theft occurred from an unattended vehicle or property. When making your report, specifically mention that the stolen item is an SIA security licence and include your licence number if you know it. The crime reference number you receive will be required during your SIA replacement application and creates an official timestamped record of when you reported the theft.

After reporting to the police, contact the SIA directly by telephone — not just through the online portal — to inform them of the theft. The SIA licensing helpline is able to flag your licence record to indicate that the physical card has been reported stolen. While this does not immediately invalidate the card in any automated enforcement system, it does create a record that if your licence card turns up in an enforcement check, officers can see that it was reported stolen and take appropriate action. This is a layer of protection for you against any fraudulent use.

It is also worth contacting your employer immediately after reporting the theft to police, since your employer has a duty of care to the venues and clients they serve. If someone were to use your stolen licence to gain employment at a venue where a crime subsequently occurred, you would not want there to be any ambiguity about the fact that your card was stolen and reported. The paper trail — police report, SIA notification, employer notification — is your protection against any suggestion of complicity.

Guards who have had their licences stolen sometimes worry about whether they could be held responsible if the card is used fraudulently before the replacement is processed. The SIA's position is that a licence holder who promptly reports a theft and applies for a replacement has fulfilled their obligation. It is the fraudulent user of the card who bears criminal liability, not the original licence holder. That said, the promptness of your reporting does matter — delaying a theft report weakens your position if questions are ever raised later.

Another concern specific to theft is whether the stolen licence could be used to pass SIA spot checks at venues or events. In reality, enforcement officers verify licences against the SIA database by licence number and cross-reference with the holder's photograph. A stolen card cannot be used effectively by someone who does not match the photo, and the SIA database will eventually flag the card as replaced once your application is processed. The practical risk of someone successfully impersonating you using a stolen SIA card is relatively low, but it is not zero — which is why reporting promptly matters.

Finally, once your replacement card arrives, it is good practice to set up some personal safeguards to reduce the risk of a repeat incident. Consider making a digital copy of your licence by photographing both sides and storing it securely in a cloud storage service you access with two-factor authentication. Note your licence number in a secure note or password manager. Some guards laminate a photocopy of their licence to keep at home as a reference document — not to use in place of the real card, but simply to ensure they always know their licence number in an emergency.

Understanding the difference between replacing a lost licence and renewing an expiring one is critical to making the right decision about which process to initiate. These are two entirely separate procedures with different forms, different fees, different timelines, and different outcomes. Confusing the two can lead to delays, unnecessary costs, and periods where your licence lapses entirely — which is far more serious than simply losing a card.

A replacement is appropriate when your licence is valid — that is, it has not yet expired — but the physical card is lost, stolen, or so damaged as to be unreadable. The replacement process issues you a new card bearing exactly the same licence number and the same expiry date as your original. You pay £25, fill in the online form, and receive a new card in the post within approximately a week. Nothing about your underlying licence changes; you are simply getting a new physical token to represent the authorisation you already hold.

A renewal, by contrast, is required when your licence is approaching its expiry date — you should begin the renewal process no later than six months before expiry to avoid any gap in your authorisation to work. The renewal process requires you to demonstrate that you still meet the SIA's fitness criteria, which includes passing background checks, confirming your right to work in the UK, and paying the renewal fee of £190.

The renewal also requires you to hold current first aid certification and to have completed any mandatory refresher training your specific licence type requires. It is a substantially more involved process.

The scenario where guards most commonly make errors is when a lost licence coincidentally occurs close to the licence's expiry date. If your licence expires in, say, two months and you lose your card today, you face a genuine decision: spend £25 on a replacement that you will only use for two months, then spend £190 on a renewal; or simply begin the renewal process now, which will issue you a new card with a fresh three-year validity period and effectively make the replacement unnecessary.

In most cases, if your licence expires within three months, starting the renewal early is the more sensible financial and practical choice.

There is, however, a complication: the renewal process typically takes longer than a replacement — sometimes four to six weeks if there are any queries on your application — so if you cannot afford to be unlicensed for that period, a replacement while simultaneously beginning the renewal may be necessary. Your employer or agency will likely have a strong view on this, since they need to maintain compliance continuously. Discuss the timeline with your employer before deciding, and consider whether your employer can redeploy you to non-licensable duties during a longer renewal wait.

It is also important to know that the SIA does not automatically extend your licence because you are in the middle of a replacement or renewal process. If your licence expires while a replacement application is pending, your authorisation to work in licensable roles expires with it. The replacement application does not freeze your licence's validity clock. This is another reason why, if your licence is close to expiry, a renewal is almost always the correct path rather than a replacement followed by a renewal a few weeks later.

Guards who hold multiple SIA licence types — for example, a Door Supervisor licence and a Security Guard licence — need to track each licence independently. The replacement or renewal of one does not affect the other, and the fees are paid separately for each.

If you have lost a card but you hold two licence types, check both records in your SIA portal account to confirm which cards are affected and whether any are also approaching renewal. This is a detail that is easy to overlook in the stress of dealing with a lost card but can have real consequences for your ability to work across different security roles.

Understanding all of these distinctions will help you avoid the expensive mistake of paying for a replacement right before needing to pay for a renewal. When in doubt, call the SIA licensing helpline — the advisors there can look at your specific licence record and tell you which process makes the most sense given your exact expiry date and circumstances. This article provides general guidance, but the SIA is the authoritative source for your individual situation.

Beyond the procedural steps of replacing a lost licence, there are several practical habits and safeguards that experienced security professionals develop over time to make sure they are never caught out by a missing card. The best time to adopt these habits is now — before you ever face the inconvenience of a lost or stolen licence. A little preparation can save enormous stress and potential earnings loss down the line.

The single most useful habit is to record your SIA licence number in at least two places that are separate from the card itself. Your phone's notes application is convenient, but consider also storing it in a cloud-based password manager or emailing it to yourself so it appears in your email history.

Your licence number is the key piece of information that allows both you and your employer to verify your status during a replacement period, and not knowing it makes the whole process more difficult. Every guard should know their number the way a driver knows their driving licence number.

Another valuable practice is to photograph both sides of your SIA licence card when you first receive it and store the image securely. A high-resolution photograph captures the licence number, expiry date, and photograph in a way that is easy to access on your phone.

You should not attempt to use this photograph as a substitute for the real card — doing so could constitute fraud — but it serves as a reference document that tells you everything about your licence at a glance. Store the photo in a secure, password-protected folder rather than your general camera roll to maintain appropriate discretion.

Keeping a copy of your licence details with your employer is also a sensible precaution. Many security companies maintain a record of their guards' licence numbers as part of their compliance management obligations, but not all do so proactively. Ask your employer or agency coordinator whether they hold your licence details on file.

If they do not, provide them with the information so it is accessible from their end if you ever need to verify your status quickly. This is also useful for your employer's licensing audit obligations — they are required to verify licences regularly, and having the number on file makes that process smoother.

When carrying your licence in the field, consider the physical environment carefully. Guards working door supervisor roles at busy venues are in environments where pickpocketing, jostling, and rough searches of suspects can all create opportunities for a card to fall out of a pocket.

A lanyard ID holder that clips shut, or a zipped inner pocket, is far more secure than a rear trouser pocket or an open breast pocket. Some guards use a specifically designed ID wallet that holds the licence in a way that allows it to be shown without being removed from the holder — reducing the risk of dropping or misplacing it during busy periods.

If you travel to multiple worksites in a day or work for multiple clients across the week, consider keeping a small dedicated card holder that contains only your SIA licence and any other essential work-related cards. When your licence lives alongside twenty other cards in a thick personal wallet, the chances of it being misplaced when you switch bags or swap clothing increase significantly. A dedicated work card holder that you transfer from uniform to uniform becomes a routine part of your kit-up process rather than an afterthought.

Finally, set a calendar reminder for your SIA licence renewal date well in advance. Six months before expiry is when you should begin gathering renewal documentation, and one year before expiry is when you should start thinking about refresher training requirements.

Guards who are on top of their renewal timeline are far less likely to find themselves in the chaotic position of dealing with an expiring licence and a lost card simultaneously — a combination that can leave you unable to work for several weeks. Proactive licence management is a mark of professionalism in the security industry and one that employers recognise and value.
