How to Start a Security Company in the UK: 2026 Legal Guide & Accreditation

Q: How long does it take to achieve SIA ACS or ISO accreditation?

With structured consultancy and ready-made compliance policies, audit preparation typically takes 6 to 8 weeks. Without guidance, building the Self-Assessment Workbook (SAW) and passing all 78 indicators can take 6 to 12 months.

Q: Do I need insurance before hiring my first security officer?

Yes. Employers' Liability insurance (£10M cover) is a strict legal requirement in the UK as soon as you employ staff. You also require Public Liability (£5M minimum) with specific inefficacy cover before dispatching officers to client sites.

⚡ 2026 UK Security Startup Summary (Quick Answer)

Can you start a security company in the UK? Yes. Anyone who meets the SIA "Fit and Proper" criteria can legally launch a private security guarding company in the UK. However, transitioning from a startup to a profitable, contract-winning business requires strict regulatory compliance:

1. Company Structure: Register a Private Limited Company (LTD) with Companies House and register with the ICO for Data Protection & CCTV handling.
2. Director Licensing: Company directors and partners must hold a valid SIA Non-Frontline Licence.
3. Mandatory Insurance: Maintain minimum £5M–£10M Public Liability (including Inefficacy cover) and Employers' Liability insurance.
4. BS 7858 Vetting: All security guards must undergo strict 5-year employment and background screening before site dispatch.
5. Industry Accreditations: While voluntary for basic trading, achieving SIA ACS, COP119, and ISO 9001 is essential to win lucrative commercial and council contracts.

The 6-Step Roadmap to Launching a Compliant Security Company

The UK private security sector is a £6+ billion industry. However, commercial clients and facilities managers will not award contracts to unverified providers. Follow this structured roadmap to build an audit-proof security firm:

STEP 1

Company Formation & ICO Registration

Incorporate your business with Companies House under standard security SIC codes (e.g. 80100 - Private security activities or 80200 - Security systems service activities). You must also register with the Information Commissioner’s Office (ICO) to comply with UK GDPR when handling client logbooks, incident reports, and CCTV surveillance footage.

STEP 2

Director SIA Licences & 'Fit and Proper' Rules

Under Section 3 of the Private Security Industry Act 2001, directors, partners, and executives of security companies must hold a valid SIA Non-Frontline Licence. If you intend to occasionally cover guarding shifts yourself, you must also hold a Frontline SIA Licence (e.g. Door Supervision or Security Guarding).

📋 SIA Licence Requirements at a Glance

Director / Partner (Managing Only): SIA Non-Frontline Licence (£190 for 3 years) + Criminal Record & Identity Check.
Director Working Shifts: SIA Frontline Licence (£190 for 3 years) with accredited training qualification.
Frontline Officers / Guards: Frontline SIA Door Supervisor / Security Officer licence + 5-year BS 7858 vetting.
The Company: Companies do not hold an individual SIA licence. To prove quality to commercial buyers, firms achieve voluntary SIA ACS Approval and COP119 Certification.

STEP 3

Specialist Security Insurance Cover

Standard commercial insurance is not sufficient. You must purchase specialist security industry insurance containing:

Public Liability (£5M–£10M): Covers property damage or third-party injury.
Employers’ Liability (£10M): Legally required the moment you assign any employee or contracted officer.
Inefficacy & Contractual Liability: Covers scenarios where security fails to prevent theft or burglary.
Wrongful Arrest Cover: Protects against civil claims arising from officer detentions.

STEP 4

BS 7858:2019 Staff Vetting Infrastructure

Every security guard you hire must be vetted to British Standard BS 7858:2019. This requires a verified 5-year employment and education history, financial probity / credit checks, enhanced criminal record checks (DBS), and right-to-work verification before conditional employment begins.

STEP 5

Subcontracting Partnerships for Immediate Scale

When you win your first 24/7 commercial contract (requiring 168 guarding hours/week), maintaining enough vetted officers in-house can strain your cash flow. Leading startups partner with established subcontractors like Eagle Security Protection to supply fully vetted, uniformed SIA guards to fulfill your contracts reliably.

STEP 6

Fast-Track Accreditations (SIA ACS, COP119 & ISO)

To win high-margin corporate tenders and commercial contracts, you must prove your management systems meet national standards. Achieving SIA Approved Contractor Scheme (ACS), COP119 Labour Provision, and ISO 9001 certification positions your business in the top tier of UK security providers.

Direct answers on startup costs, licensing timelines, and accreditation requirements in the UK.

How much does it cost to start a security company in the UK?

Starting a lean security company typically costs between £3,500 and £8,000 for company incorporation, ICO registration, director SIA Non-Frontline licensing, specialist liability insurance, BS 7858 vetting software, and uniforms.

Yes. Partnering with an established, accredited subcontractor like Eagle Security Protection allows you to bid on and deliver large contracts immediately, using our audited guarding infrastructure while you build your own company track record.

Yes. Employers’ Liability insurance (£10M) is a strict legal requirement the moment you hire or assign staff. Public Liability (£5M-£10M) with inefficacy cover is also required by almost all commercial clients.
