How Do I Hire Security for My Business? (2026 Guide)

Last updated: 29 October 2026

Hiring security for your business starts with an honest assessment of risk, then checking every candidate guard or contractor holds a valid Security Industry Authority (SIA) licence — a legal requirement for most frontline roles under the Private Security Industry Act 2001. Around 440,000 people currently hold an SIA licence in the UK, according to Marble Arch London, citing the Security Industry Authority (2024).

Key Takeaways

• The Security Industry Authority licenses door supervisors, security guards and CCTV operators under the Private Security Industry Act 2001, and roughly 440,000 people hold an SIA licence, according to Marble Arch London (2024).
• Priority First notes that every UK employer hiring security staff must carry employer's liability insurance, a legal obligation under the Employers' Liability (Compulsory Insurance) Act 1969.
• A full risk assessment — covering access points, footfall, stock value and out-of-hours exposure — should always precede any decision to hire guards, CCTV or both.
• Priority First has delivered more than 4,900 photo-backed patrols across a 24-site portfolio, with every checkpoint logged by officer ID, GPS and timestamp (as of August 2026).
• Businesses should request a written contract or service level agreement specifying coverage hours, reporting standards, insurance limits and escalation procedures before signing with any security provider.

What type of security does my business actually need?

Business security is the combination of guarding, technology and procedure a company puts in place to protect people, premises and assets from theft, intrusion and disorder. The right mix depends entirely on your sector, site layout and the hours you operate.

A central London retail unit with high footfall and valuable stock has very different needs from a half-built construction site in the West Midlands or a 96-unit care home in Bedfordshire. Most businesses need some combination of the following.

• Manned guarding — SIA-licensed officers on site for access control, patrols and visible deterrence.
• CCTV monitoring — round-the-clock remote surveillance with trained operators who can escalate incidents in real time.
• Door supervision — SIA-licensed staff managing entry to licensed premises, events or high-traffic venues.
• Key holding and alarm response — a nominated keyholder who attends alarm activations instead of your own staff.
• Cyber security — a separate discipline entirely, covering network, data and systems protection, usually sourced from an IT security specialist rather than a physical security provider.

Priority First's guide, Building Security Audit: Self-Assessment, walks businesses through identifying which of these gaps actually apply to their premises before any contract is signed. A care home in Bedfordshire with 96 units faced exactly this question: care staff could not also act as the overnight security presence, so the home needed SIA-licensed officers dedicated to door control and night patrols, with every checkpoint documented rather than assumed.

Do security companies in the UK need to be licensed, and how do I check?

The Security Industry Authority is the statutory body that licenses individuals carrying out licensable security activities in the UK, including manned guarding, door supervision and CCTV operation, under the Private Security Industry Act 2001. Any business engaging guards for these roles must confirm each individual holds a current SIA licence before they start work.

You can verify a licence instantly using the SIA's public register, available via GOV.UK's Security Industry Authority page. Simply search the licence number printed on the badge the officer should be wearing visibly at all times.

Beyond individual licences, some security companies also hold SIA Approved Contractor Scheme status — a separate, voluntary accreditation recognising quality management standards. Always ask a prospective provider which licences their deployed officers hold and request to see the register confirmation yourself rather than taking their word for it.

The SIA's Get Licensed criteria document sets out exactly which roles require licensing and the qualifications behind them. The National Protective Security Authority's summary of SIA licences is also a useful reference for understanding the different licence categories — frontline versus non-frontline — before you start interviewing providers.

Should I hire an in-house security team or outsource to a contract company?

In-house security means directly employing guards as staff on your payroll, while outsourced security means contracting a third-party company that supplies trained, licensed officers under a service agreement. Most UK businesses outside very large estates choose outsourcing because it removes recruitment, training, licensing checks, holiday cover and payroll administration from their own workload.

The trade-off is control versus convenience, and it is worth weighing carefully against your size and risk profile.

Priority First's portfolio work illustrates the outsourced model at scale. One London and UK-wide operator runs 24 sites and more than 11 field officers on a single platform, with every patrol, incident, delivery and alarm response logged centrally rather than scattered across paper occurrence books that left with each departing officer.

"Asking a member of staff to attend their own premises at three in the morning is asking them to walk into the unknown alone. Professional keyholding exists so that the person opening that door is trained for the moment the alarm turns out to be real — and so your people never have to be." — Mo Hassan, Managing Director, Priority First

What questions should I ask a security company before signing a contract?

A security contract negotiation should surface the provider's licensing compliance, insurance cover, staffing continuity and reporting standards before any commitment is made. Ask these questions directly and insist on written answers, not verbal assurances.

1. Can you confirm every deployed officer's SIA licence number, and will you provide proof on request?
2. What is your public liability and employer's liability insurance cover, and can I see the certificate?
3. How do you handle staff sickness or sudden absence — is replacement cover guaranteed within a stated timeframe?
4. What does your patrol reporting look like — paper logs, or a digital system with timestamps and photographic evidence?
5. What is your average response time for an emergency callout or alarm activation?
6. Do you carry references from similar clients in my sector that I can contact directly?
7. What happens if an officer fails to attend — is there a penalty clause or service credit in the SLA?

A mixed-use development in West London asked precisely this kind of question after years of taking patrol completion on trust. The daily occurrence book always read "all in order," but nobody could prove which plant room had actually been checked at 3am. Priority First answered that gap by making all 152 checkpoints across retail, residential, service yards and plant rooms require a timestamped, GPS-tagged photograph to complete — turning an assumed patrol into a provable one, live since February 2026, with more than 540 patrols completed across the first five months.

How much does hiring business security typically cost in the UK?

Security guarding costs in the UK vary by location, hours of cover, licensing level and whether you need a single static post or a multi-site patrol team. UK-specific published pricing data is limited, but the structure of costs is consistent: hourly rates, shift patterns, and whether cover is 24/7 or part-time all drive the final figure.

For comparison, US Bureau of Labor Statistics data shows security guards earned a mean of $20.42 per hour in the United States as of May 2025, according to BLS via Blinkless (2025), while the median annual wage for security guards alone stood at $38,370 in May 2024, according to the BLS Occupational Outlook Handbook, cited by Boostpoint (2024). A fully loaded 24/7 guard post in California costs approximately $322,121 per year, based on a wage of $21.60/hr plus employer burden, according to the Blinkless Guard Cost Calculator (2026).

These US figures illustrate how dramatically total cost of ownership — wages plus employer burden, supervision, equipment and administration — exceeds the headline hourly rate; UK buyers should expect the same multiplier effect when comparing quotes. Always ask a UK provider for an all-in monthly figure rather than comparing bare hourly rates, since insurance, uniform, training and management overhead are frequently bundled differently between quotes.

Ways to reduce costs:

• Combine CCTV monitoring with reduced static guard hours rather than full-time presence.
• Use mobile patrol visits instead of a fixed on-site officer where risk allows.
• Bundle security with facilities management under one provider to cut duplicate administration.

Alternatives to consider:

• Remote CCTV monitoring with rapid-response callout instead of a permanent guard.
• Keyholding and alarm response only, for sites that don't need constant physical presence.
• Canine security units for deterrence on large sites like construction or logistics yards.

What legal and insurance obligations do I have as an employer hiring security staff?

Employer's Liability Insurance is a legal requirement under the Employers' Liability (Compulsory Insurance) Act 1969 for any UK business with employees, including security staff hired directly. Businesses outsourcing to a contract security provider should confirm that provider carries its own employer's liability and public liability insurance, since the contracted guards remain that company's employees, not yours.

The Health and Safety at Work etc. Act 1974 places a duty on employers to ensure, so far as reasonably practicable, the health, safety and welfare of all employees — including security personnel working night shifts, lone duties or high-risk environments. The Health and Safety Executive (HSE) enforces this duty and can act where lone-working or violence-at-work risks have not been properly assessed.

If your security provider handles personal data through CCTV footage, visitor logs or access records, data protection obligations under UK GDPR apply, and the Information Commissioner's Office (ICO) is the relevant regulator. A written contract should state clearly who is the data controller for any CCTV footage captured on your premises.

What should be included in a security contract or service level agreement?

A security service level agreement (SLA) is the written document defining exactly what a provider will deliver, to what standard, and what happens if they fail to deliver it. Every SLA should specify coverage hours, named sites, reporting format, insurance levels, escalation procedures and notice periods for termination.

Beyond the basics, look for measurable, auditable commitments rather than vague assurances. Priority First builds this directly into its operating model: alarm activations are logged in the field with cause, actions and photographs, false-alarm counts are tracked per site against the police-response threshold, and shift handovers are generated automatically from the shift's recorded events rather than written from memory.

A well-structured SLA should also define a duress and escalation protocol — a silent alert system behind each officer's PIN with a named responder and a route to police, should an incident demand it. Ask any prospective provider to show you what their incident reporting actually looks like, not just describe it, before you sign.

Your business security hiring checklist

• Carry out a risk assessment covering access points, footfall, stock value and out-of-hours exposure.
• Verify every proposed officer's SIA licence on the public register via GOV.UK.
• Request proof of the provider's public liability and employer's liability insurance certificates.
• Compare at least two providers' all-in monthly costs, not just hourly rates.
• Insist on a written SLA specifying coverage hours, reporting standards and escalation routes.
• Ask for references from clients in a similar sector and actually contact them.
• Confirm how patrols, incidents and deliveries are logged — paper, or a digital, photo-backed system.
• Agree a notice period and penalty clause for missed shifts before signing.

FAQ

How do I hire security for my business quickly in an emergency?

Contact a provider with rapid deployment capability and confirm they can mobilise an SIA-licensed officer within hours, not days. Priority First deployed an SIA operative to a broken-into Covent Garden site within two hours of first contact — call logged at 12:30, quote agreed on the call, officer on site by 14:30.

Do I legally need an SIA-licensed guard, or can anyone do the job?

Yes, most frontline security roles — manned guarding, door supervision and CCTV operation — legally require an SIA licence under the Private Security Industry Act 2001. Working without one is a criminal offence for both the individual and, potentially, the hiring business.

What's the difference between a security guard and a door supervisor?

A security guard typically patrols, monitors and protects premises and assets, while a door supervisor manages entry and behaviour at licensed venues, events or high-footfall entrances. Both require separate SIA licence categories, and a provider should confirm which licence each deployed officer holds.

How many security guards does my business actually need?

The right number depends on site size, opening hours, access points and risk level, which is why a structured risk assessment should always precede staffing decisions. A single 24/7 post typically requires several full-time-equivalent staff to cover shifts, holidays and sickness without gaps.

Is CCTV monitoring enough, or do I need guards on site too?

CCTV monitoring provides remote visibility and recorded evidence but cannot physically intervene, challenge an intruder or manage access control the way an on-site guard can. Most medium and high-risk premises combine both — CCTV for continuous coverage and guards for physical presence and response.

How do I check a security company's reputation before signing?

Ask for client references in your sector, check independent review platforms, and request evidence of how they document patrols and incidents rather than relying on their sales pitch alone. Priority First holds a 5.0-star rating from 63 Google reviews, as of September 2026.

What happens if my security provider's guard fails to turn up for a shift?

A properly written contract should include a guaranteed replacement-cover clause and may include service credits or penalties for missed shifts. Always query this specifically before signing, since cover continuity is one of the most common failure points in outsourced security.

Securing your business with Priority First

Hiring the right security for your business means matching the risk on your premises to a provider that can prove — not just promise — the cover it delivers. Priority First builds that proof into every contract: patrols, incidents, deliveries and alarm responses are logged on one platform with officer ID, GPS and timestamp attached to every checkpoint.

Across its largest portfolio, Priority First now runs 24 sites and more than 11 field officers on this system, with over 4,900 photo-backed patrols completed as of August 2026, and documented contracts in place for 37 clients, including 28 across Chelsea and Knightsbridge. New sites have been taken live in as little as a fortnight, including a ten-checkpoint serviced residence, with the first provable patrol typically delivered within days rather than the weeks it usually takes to bed in a new security contract.
