If you want to work in private security in the UK, you will almost certainly come across the term “SIA licence“. There is more than one type, though, and choosing the wrong one can cost you time and money. There are two categories of SIA licence, front line and non-front line. Front line licences cover hands-on security work. They include five manned guarding licences (security guard, door supervisor, public space surveillance (CCTV), close protection, and cash and valuables in transit) plus a key holding licence. Non-front line licences are for managers, supervisors and directors who do no front line work themselves. In Northern Ireland only, there is also a vehicle immobiliser licence. This guide explains each type in plain English, who needs which licence, what it costs, how to apply and the mistakes beginners should avoid.

The Security Industry Authority (SIA) regulates the private security industry in the UK. It issues licences to people who carry out certain security activities, known as “licensable activities”.
Licensing makes sure people doing security work have been checked (including identity and criminal record checks) and, for front line roles, have completed approved training. If you work in private security without the licence you need, you may be breaking the law.
An SIA licence is not the same as a training certificate. The qualification shows you have completed approved training. The licence is the permission the SIA grants after checking your application.
The SIA splits licences into two categories.
You need a front line licence if you personally carry out a licensable front line activity as part of your job. This applies whatever your job title, so a manager or director who does front line work also needs one. Most front line licences are issued as a plastic photocard that you must wear while working. The exception is the key holding licence, which is issued as a letter. If your job involves covert activity, such as a store detective, you do not need to display your licence.
All front line licences also allow you to do the activities covered by a non-front line licence.

There are five manned guarding licences.
What it covers: guarding premises or property against damage, theft, unauthorised access or disorderly behaviour.
Who may need it: guards in shops, offices, shopping centres, warehouses and building sites.
Practical example: a guard employed by a security company and placed at a retail park.
Limitation: it allows some use of CCTV to guard premises against unauthorised access or property against damage or theft. It does not cover CCTV used to guard premises against disorder or damage, or people against injury or assault. That needs a public space surveillance (CCTV) licence.
What it covers: guarding licensed premises (venues licensed to sell alcohol for consumption on the premises or to provide regulated entertainment) against damage, theft, unauthorised access or disorderly behaviour.
Who may need it: door staff at pubs, bars, nightclubs and some events.
Practical example: checking entry and removing a disruptive customer from a nightclub.
Good to know: it also allows you to work as a security guard.
What it covers: using closed circuit video surveillance to identify people or monitor their activities in order to guard premises against disorder or damage, or to guard people against injury or assault caused by others’ unlawful conduct. This includes viewing recorded footage.
Who may need it: CCTV control room operators.
Practical example: monitoring town centre cameras and alerting the appropriate people to an incident.
Good to know: it also allows CCTV use for security guarding purposes.
What it covers: guarding people against physical assault or injury.
Who may need it: bodyguards and close protection operatives.
Practical example: protecting a client during a visit to the UK.
Good to know: it also allows you to do door supervisor and security guard work, and to use CCTV to guard premises against unauthorised access or property against damage or theft.
What it covers: guarding property against damage or theft while transporting it in a vehicle designed for secure transportation.
Who may need it: crew members of secure cash-carrying vehicles.
Practical example: collecting and delivering cash to retailers or banks in a secure vehicle.
What it covers: security work that involves keeping, or controlling access to, any key or device for operating a lock.
Who may need it: people who hold keys on behalf of clients and, for example, respond to alarm activations.
Good to know: it is a front line licence, but you do not need a licence-linked qualification to get one. It is issued as a letter rather than a photocard. If your call-outs may involve manned guarding activity, you will also need the relevant front line licence and its qualification.
This front line licence applies only to security operatives in Northern Ireland. It covers work that involves preventing or restricting the movement of a vehicle, or removing it, and then charging the owner to release it (for example, wheel clamping).
You need a front line or non-front line licence if you manage, supervise or employ people who carry out licensable activities. The same applies if you are a director of a company or partner in a firm where others do. A non-front line licence is issued as a letter and also allows you to carry out key holding. You do not need a licence-linked qualification to get one.
Practical example: the operations manager of a security company who never works a post personally.
| Licence | Typical job role | Purpose | Qualification considerations |
|---|---|---|---|
| Security guard | Retail, site or office security officer | Guarding premises or property | Licence-linked qualification; first aid qualification before training |
| Door supervisor | Pub, bar or club door staff | Guarding licensed premises | Licence-linked qualification; first aid qualification before training |
| Public space surveillance (CCTV) | Control room operator | Monitoring people using CCTV | Licence-linked qualification |
| Close protection | Bodyguard | Guarding people from assault or injury | Licence-linked qualification; Level 3 first aid before training |
| Cash and valuables in transit | Secure vehicle crew | Guarding cash or valuables in transit | Licence-linked qualification |
| Key holding | Key holder or alarm responder | Keeping or controlling access to keys | No licence-linked qualification required |
| Non-front line | Manager, supervisor or director | Managing others who do licensable work | No licence-linked qualification required |
A simple way to choose: start from the job you actually want, ask the employer which licence it requires, and only then book training. Do not choose a licence just because it sounds more impressive.

According to the SIA, you do not need a licence if you:
Most in-house security staff, meaning people employed directly by the organisation that uses their services, do not usually need a licence either. There are important exceptions. Door supervision at licensed premises needs a licence even when you work in-house, and the same applies to vehicle immobilising in Northern Ireland. If your situation is not clear-cut, check the SIA’s guidance or ask the SIA directly.

The SIA checks the following when you apply.
Mandatory or employer preference? The items above come from the SIA’s licensing criteria. Anything else, such as driving licence requirements, experience or particular certificates, is set by individual employers.
The SIA updates its criteria from time to time. The official application and renewal guidance names the May 2026 edition of the Get Licensed booklet as the current criteria, so read it before applying.
According to the SIA’s application guidance, if you live outside the UK, or have spent 6 continuous months or more outside the UK in the last 10 years, you need to provide evidence of overseas criminal record checks. If the SIA asks for evidence of your right to work and does not receive it within 21 days, it cancels the application.
The SIA says applying does not guarantee you will get a licence.

The official SIA licence application fee is £204. The same fee applies to first-time applications and renewals.
Some things to know:
Other costs (not part of the SIA fee):
Training prices vary a lot between providers, so compare what is included (course, exam, first aid, certificate) rather than only the headline price.

Front line SIA licences are valid for 3 years. Your licence does not renew automatically, so diarise your expiry date.
The SIA’s training page lists refresher qualifications for door supervisor, security guard and close protection only. It lists none for CCTV or cash and valuables in transit, but check the current guidance before you renew. If it has been more than 3 years since your last licence was active, you need a full new qualification rather than a refresher.

There are two categories: front line and non-front line. Front line licences include security guard, door supervisor, public space surveillance (CCTV), close protection, cash and valuables in transit, and key holding. Non-front line licences are for managers, supervisors and directors who do not carry out front line work. Vehicle immobiliser licences apply only in Northern Ireland.
There is no single best licence, because it depends on the job you want. Security guard and door supervisor are common starting points because they are widely used roles. Check what local employers require before booking training, and remember a door supervisor licence also allows you to work as a security guard.
Often not. If you work under a contract for services, such as an agency placing you at a client’s site, you generally need a licence. In-house guards employed directly by the organisation they protect do not usually need one, but door supervisors at licensed premises always do. Working without a required licence may be a criminal offence.
No. The qualification is the training certificate you gain from an approved provider. The licence is the permission the SIA grants after checking your application, including identity, right to work and criminal record. Having the qualification does not guarantee a licence, and key holding and non-front line licences need no licence-linked qualification.
The official application fee is £204 for a first application or renewal. A 50% discount applies to additional licences only when they are on the same application. Training and first aid courses are extra and vary by provider.
The SIA cannot give an exact time because many factors affect it. It offers a decision timescale indicator on its website that gives an estimate based on the details you enter. It is not a guarantee. Applying early and having your identity documents ready can help avoid avoidable delays.
Sometimes. A door supervisor licence also covers security guard work. A close protection licence also covers door supervisor and security guard work. A CCTV licence also allows CCTV use for security guarding purposes. All front line licences allow non-front line activities. Check the SIA’s guidance for the exact scope.
Renewal is not automatic. Apply through your SIA online account up to 4 months before expiry. You will pay £204, complete identity and criminal record checks again, and for door supervisor, security guard and close protection licences you must hold the relevant refresher qualification and first aid qualification first.
Possibly. Not every conviction automatically prevents you from getting a licence, and the SIA assesses each case against its criteria. You can use the SIA’s criminal record indicator before applying to see whether your record might affect your application.
Log in to your SIA online account, where you can track the progress of your application. Your employer or training provider may also be able to help if they submitted it for you. Do not create a second account if you forget your password. Reset it instead.
SIA licence types come down to what you actually do at work. Front line licences cover guarding, door supervision, CCTV monitoring, close protection, cash and valuables in transit and key holding. Non-front line licences are for managers and directors who do no front line work.
Before you pay for training or an application, confirm which SIA licence your intended role requires. Check you meet the age, right to work and criminal record criteria, and use the official SIA and GOV.UK pages for current fees and rules. The £204 fee is not refundable, and training requirements have changed in recent years, so it is worth getting the details right first.
