Hiring a new security guard is only the first step. Before that guard is deployed to a site, your company needs to complete a series of compliance checks and administrative steps — each of which, if missed, can expose you to legal risk, contract failure, or an ACS audit finding.
This guide walks through a structured onboarding process for new security guards, covering every checkpoint from offer acceptance to first shift.
Why Guard Onboarding Is a Compliance Process, Not Just HR Admin
In most industries, onboarding is largely a paperwork exercise. In private security, it is a legal and regulatory obligation. A guard who is deployed before checks are complete is not just an HR problem — it is potentially a criminal matter under the Private Security Industry Act 2001. The company, not just the individual, bears liability for unlicensed deployments.
A thorough onboarding process also protects you commercially. Guards who understand your standards, your sites, and your expectations from day one perform better, cause fewer incidents, and stay longer. Rushed onboarding is one of the leading causes of early-tenure turnover in the industry.
Step 1: Verify the Right to Work in the UK
Before any offer is confirmed, you must conduct a Right to Work check in accordance with the Home Office Code of Practice. This requires examining original documents — not copies — and retaining a record of the check date and documents seen.
Acceptable documents include a UK or Irish passport, a share code from the Home Office online checking service (for non-British/Irish nationals), or other specified documents from List A or List B of the Home Office guidance.
A failed or missed Right to Work check can result in a civil penalty of up to £60,000 per illegal worker. There is no statutory defence for missing the check once an employment relationship begins.
Step 2: Verify the SIA Licence
Every guard deployed in a licensable role must hold a valid SIA licence. Check the licence before the first deployment — not at some point during the first week — using the SIA Public Register. Confirm that:
- The name on the licence matches the person in front of you
- The licence category matches the role they will be performing
- The licence status is Active, not Expired, Revoked, or Suspended
- The expiry date is noted and added to your renewal tracking system
Record the check date, the licence number, and the result in the guard’s personnel file. This record is essential evidence in the event of an ACS audit or an SIA compliance inspection.
Step 3: Collect and File Pre-Employment Documentation
Beyond Right to Work and SIA verification, a complete pre-employment file should include:
- Signed employment contract or self-employment agreement (with IR35 status clearly documented if using self-employed workers)
- BS 7858 security screening evidence — employment history references, identity verification, and a five-year work history check are standard for ACS-compliant companies
- Emergency contact information
- Bank details for payroll
- National Insurance number
- Confirmation of any relevant additional training certificates (first aid, manual handling, conflict management)
BS 7858 screening is not a legal requirement for all private security roles, but it is a requirement for ACS membership and is increasingly expected by commercial and public sector clients as a condition of contract. If you do not currently carry out BS 7858-aligned screening, it is worth implementing regardless of ACS status.
Step 4: Issue Equipment and Uniform
Before the first shift, every guard should be issued with everything they need to perform their role. This typically includes:
- Uniform to the company standard, correctly fitted
- SIA badge holder or clip (SIA licences must be visibly worn at all times when on duty)
- Any site-specific PPE (high-visibility clothing, safety footwear)
- Any equipment required for the role (torch, radio, body-worn camera if used)
- A copy of the assignment instructions for their first site
Equipment issuance should be documented — both to manage inventory and to provide evidence in the event of loss or damage claims.
Step 5: Complete the Company Induction
A company induction covers the policies and procedures that apply to every guard, regardless of site. This should include:
- Code of conduct and standards of behaviour
- Reporting structure — who the guard reports to, who to call in an emergency, who to contact if they cannot attend a shift
- Absence and late-notification procedures (this is the moment to establish your expectation around no-shows)
- Incident reporting procedure and what constitutes a reportable event
- Lone worker policy and check call requirements
- Uniform and presentation standards
- Use of company equipment and mobile devices
- Data protection and confidentiality obligations
The induction should be completed before deployment, not during the first week. A guard who arrives at site without having been through induction is more likely to make avoidable mistakes, and you lose the ability to evidence that procedures were communicated.
Step 6: Complete the Site Induction
Each site has its own specific requirements: access points, key holder contacts, alarm codes, post orders, escalation protocols, and client-specific rules. A site induction is distinct from the company induction and should be completed for every new site a guard is assigned to, even if they are an experienced member of the team.
The site induction should be documented with the guard’s signature confirming they have received and understood the site-specific instructions. This documentation is particularly important for sites with complex procedures or high-security requirements.
Step 7: Add the Guard to Your Management System
Once all the above steps are complete, the guard’s profile should be active in your guard management platform — licence expiry tracked, training records added, and shift assignments ready to go.
TacDesk provides a centralised guard profile for each team member, storing SIA licence details, expiry dates, and associated documentation in one place. Automated alerts notify management when a licence is approaching expiry, so no guard slips through the gap between onboarding and first renewal.
Onboarding as a Retention Tool
Research consistently shows that employees who experience a structured, well-organised onboarding process are more likely to remain with an employer beyond their first six months. In the security industry, where turnover rates are disproportionately high, this matters financially. Replacing a guard typically costs several hundred pounds in recruitment, screening, and administrative time — and that is before factoring in the operational disruption.
A well-run onboarding process signals to new guards that your company is professional, organised, and worth staying with. It sets the tone for the employment relationship from day one.
Summary
Onboarding a new security guard correctly takes more than a brief induction and a handshake. Right to Work checks, SIA verification, BS 7858 screening, equipment issuance, company induction, and site induction are each non-negotiable steps — and each needs to be documented. Getting this right protects your business legally, supports ACS compliance, and gives your newest guards the best possible start.
