A security licence is not simply a line on a CV. It determines where you can legally work, which roles you can apply for and whether an employer can place you on site. For candidates considering PSA versus SIA licensing, the key difference is jurisdiction: PSA licensing applies in the Republic of Ireland, while SIA licensing applies in Northern Ireland and the rest of the UK.
That distinction matters most when you live close to the border, move between regions for work, or see similar-looking vacancies advertised on both sides. A valid licence from one authority should not be assumed to meet the requirements of the other.
PSA versus SIA licensing: the core difference
The Private Security Authority (PSA) regulates relevant private security activity in the Republic of Ireland. The Security Industry Authority (SIA) regulates the private security industry in Northern Ireland, England, Scotland and Wales. Both systems exist to raise standards, support public safety and give employers confidence that frontline staff have completed the required training and vetting.
They are separate regulators with separate application processes, training routes, licence categories and renewal rules. Holding a PSA licence does not automatically give you the right to carry out a licensable role under the SIA system. Equally, an SIA licence is not a substitute for PSA licensing when a role in the Republic requires it.
For jobseekers, the practical rule is straightforward: check where the site is located, read the licence requirement in the vacancy and make sure your licence matches the work you will actually be doing.
Where can you work with each licence?
A PSA licence is relevant for licensable security work in the Republic of Ireland. Depending on the sector and role, this can include security guarding, door supervision, CCTV monitoring and other regulated security activities. Employers will normally expect you to hold the correct active licence before deployment, particularly where a contract demands licensed staff.
An SIA licence is relevant for licensable work in Northern Ireland and elsewhere in the UK. Common frontline licence routes include security guarding, door supervision, CCTV operation and close protection. The right licence depends on the duties attached to the role, not merely the job title.
For example, a retail security officer in Dublin may need the appropriate PSA licence. A door supervisor working at a Belfast venue will need to meet the relevant SIA requirements. A candidate based in Newry who wants the flexibility to work in both jurisdictions may need to pursue the appropriate licence for each market rather than relying on one credential.
This is especially important for mobile patrol, event security and security companies operating near the border. The location of the assignment and the nature of the duties should always guide the compliance decision.
Similar job titles can require different licences
Security job titles are not always used consistently. A vacancy described as “security officer” could involve access control, gatehouse duties, patrols, incident reporting and customer-facing work. Another role with the same title could include CCTV monitoring or door supervision responsibilities that require a different licence category.
Before applying, look beyond the title. Check the job description for the site type, shift pattern, public-facing responsibilities, use of CCTV and whether you are expected to manage entry to licensed premises or events. If the role includes duties outside the scope of your current licence, ask the employer for clarification before accepting work.
Door supervision is a good example. In both jurisdictions, it is a distinct area of work with demanding public-facing responsibilities. A door supervision vacancy may involve conflict management, customer service, incident recording, searching procedures and working late-night shifts. It should not be treated as interchangeable with a static guarding role simply because both sit within the wider security sector.
Training and application routes are different
Both PSA and SIA licensing depend on approved training and suitability checks, but the qualification names, provider requirements and application steps are not identical. Candidates should choose a course that is approved and recognised for the licence they intend to apply for.
If you plan to work in the Republic, look for training that supports the relevant PSA licence route. If your goal is work in Northern Ireland, make sure the course meets SIA requirements. A course may be valuable for general skills development, but that does not mean it will support every licensing application across both systems.
Vetting is also central. Employers in security need people they can trust with premises, people, information and assets. Be prepared to provide accurate identification, address history and any other information requested by the licensing authority or employer. Incomplete records and avoidable mistakes can delay an application, which can in turn delay your start date.
For new entrants, it is worth planning your route before paying for training. Decide where you want to work, the roles you are targeting and whether you are willing to travel. That helps you select the right approved course first time and avoid holding a qualification that does not match your preferred job market.
What employers should check before hiring
For employers, licence checking is not a box-ticking exercise. A candidate may have genuine security experience but still hold a licence that is expired, for a different category or issued for work in another jurisdiction. Verifying this early protects the business, the client and the worker.
A clear vacancy should state the work location, licence authority, licence category and whether applicants must already be licensed or can be licence-track candidates. It should also explain the core duties rather than relying on a broad title. This reduces unsuitable applications and helps candidates make an informed decision before applying.
Employers hiring across Ireland and Northern Ireland should build licence checks into their recruitment and deployment process. The same person may be suitable for roles in both regions, but only if they meet the separate legal and contractual requirements for each assignment.
Can you hold both a PSA and SIA licence?
Yes, provided you meet the requirements of each authority. For some professionals, holding both can widen the range of vacancies available, particularly in border areas or for those seeking event, guarding or corporate security work across multiple locations.
However, it is not automatically the best option for everyone. Two licences can mean separate training obligations, application fees, renewal dates and administrative responsibilities. If you work only in one jurisdiction, maintaining a second licence may not offer enough value to justify the cost and effort.
Consider both licences if you regularly see suitable vacancies on either side of the border, if your employer operates in both markets, or if flexibility is a priority. If you are starting out, it is often more practical to obtain the licence that matches the area where you can realistically commute and build experience first.
Keep your licence details job-ready
Once licensed, keep your professional profile current. Add the licence authority, category, expiry date, training completed and the locations where you are available to work. Employers need to make quick, compliant hiring decisions, especially for cover shifts, events and new contract mobilisation.
It also helps to be precise about your experience. State whether you have worked in retail, corporate reception, construction, healthcare, transport, events, mobile patrols or CCTV control rooms. Include shift availability, driving status where relevant and any specialist experience such as report writing, access systems or lone working.
On Security Jobs Ireland, candidates can present their PSA or SIA licence information alongside their CV and search for roles that match their location and specialism. Employers benefit from direct access to security-focused applicants, without the delay or commission costs associated with a traditional recruitment agency.
Your licence should support your next move, not limit it. Check the jurisdiction before you train, verify the licence category before you apply and keep your details accurate. That preparation gives employers confidence and puts you in a stronger position when the right shift, contract or permanent role becomes available.
