When security business owners think about staffing costs, they typically think about the hourly rate. But that figure captures less than half the story. The true cost of employing a security guard in the UK in 2026 is considerably higher than the wage alone — and understanding the full picture is essential for accurate pricing, contract margins, and sustainable growth.
This guide breaks down every component of security guard employment costs so you can build pricing models that actually protect your business.
The Hourly Rate: Your Baseline
As of April 2026, the National Living Wage for workers aged 21 and over is £12.21 per hour. In practice, many security companies pay above this — particularly for SIA-licensed door supervisors, CCTV operators, or roles requiring specialist skills — where rates of £13 to £16 per hour are common in urban areas.
For a full-time guard working 40 hours per week at £12.21, the gross wage cost is approximately £25,397 per year.
But that’s just the base.
Employer National Insurance Contributions
From April 2025, the employer National Insurance rate increased to 15%, with the secondary threshold reduced to £5,000 per year. This means employers pay NI on earnings above £5,000.
For a guard earning £25,397:
- Taxable earnings above threshold: £25,397 − £5,000 = £20,397
- Employer NI at 15%: £3,060
The Employment Allowance may offset some of this for smaller firms, but cannot be relied upon as your cost model grows.
Statutory Holiday Pay
Full-time workers are entitled to 28 days of paid annual leave (5.6 weeks), including bank holidays. For a guard earning £25,397, this equates to approximately £2,745 in holiday pay per year (i.e. 10.77% of pay).
Many security companies run 24/7 operations with staff working irregular patterns, bank holidays, and nights — which makes holiday accrual calculations more complex. Errors here are common and can result in back-pay claims.
Workplace Pension (Auto-Enrolment)
Employers must contribute a minimum of 3% of qualifying earnings to a workplace pension. For a guard earning £25,397, qualifying earnings are calculated on income between £6,240 and £50,270.
Employer pension contribution: approximately £577 per year.
SIA Licence Costs
Every frontline security operative working under a contract for services must hold a valid Security Industry Authority (SIA) licence. The current licence fee is £184 for three years (roughly £61/year).
Some employers contribute to or fully fund licence renewals as part of their retention strategy. First-time licences also require an approved training course — commonly a Level 2 Award for Door Supervisors or Security Guards — which costs between £300 and £800 depending on the provider and format.
If you’re funding initial licensing, the amortised annual cost per guard is typically £160–£330 over the first three-year cycle.
BS 7858 Vetting
Most professional security employers conduct pre-employment vetting in line with BS 7858, covering identity checks, five-year employment history, criminal records, and financial probity. Third-party vetting typically costs £30 to £80 per candidate.
When you factor in a typical 12-month employment duration for frontline guards — and the associated recruitment and onboarding costs — annualised vetting cost per head is commonly £50–£100.
Uniform and Personal Protective Equipment
Uniform provision (shirt, trousers, jacket, boots, ID lanyard) typically costs £150 to £300 per guard on initial issue, with ongoing replacement costs of around £75–£150 per year thereafter.
Training and Continued Development
Beyond initial licensing, guards may require site-specific inductions, first aid certificates, fire marshal training, or conflict management refreshers. Budget an average of £100–£200 per guard per year for ongoing training costs.
Management and Administrative Overhead
This is the cost most often overlooked. Every guard on your payroll requires:
- Rota and scheduling management
- Payroll processing
- SIA licence monitoring and renewal tracking
- Incident reporting oversight
- Clock-in/clock-out verification
- Holiday and absence management
At manual scale, industry estimates suggest a single operations manager can effectively manage around 30–50 guards using spreadsheets and manual processes. That overhead cost, amortised across a team, adds £800 to £1,500 per guard per year at typical management salaries.
The Full Picture: A True Cost Model
Here’s a realistic annual cost summary for one full-time SIA-licensed security guard at National Living Wage:
| Cost Component | Annual Estimate |
|---|---|
| Gross wages (40hr/wk @ £12.21) | £25,397 |
| Employer NI (15%) | £3,060 |
| Holiday pay (10.77%) | £2,745 |
| Employer pension (3%) | £577 |
| SIA licence (amortised) | £61 |
| BS 7858 vetting | £75 |
| Uniform and PPE | £150 |
| Training | £150 |
| Management overhead (conservative) | £1,000 |
| Total annual cost | £33,215 |
That’s a true employment cost of roughly £16.00 per hour for a guard you’re billing at £12.21. Your blended margin before any other business costs is considerably thinner than the raw wage comparison suggests.
Reducing Management Overhead with Technology
The management overhead component — typically £800 to £1,500 per guard per year — is the most controllable item on the list. Guard management software replaces manual scheduling, automates SIA licence expiry alerts, digitises incident and patrol reports, and provides real-time GPS clock-in/clock-out verification.
Platforms like TacDesk charge from £1 to £2.50 per guard per month — or £12 to £30 per guard per year. At that cost, even a conservative 20% reduction in management overhead delivers a return of 25:1 or better.
For security companies looking to grow beyond 50 guards without proportionally scaling headcount in the office, this is the most reliable lever available.
Key Takeaways
- The true annual cost of a security guard at NLW is approximately £33,000 — around 31% above gross wages
- Employer NI increases from April 2025 have added £600–£900 per full-time guard compared to 2024
- Management overhead is the largest variable cost — and the most reducible through technology
- Factor these numbers into your contract pricing to protect margins and build a sustainable business
