You’ve won the contract. A prestigious client, a secure site, a team of guards ready to deploy. Then comes the fine print: “All personnel must be vetted to BS7858 standard.” 

For security companies, this is both a mark of credibility and a significant operational expense. BS7858 isn’t just a background check—it’s a comprehensive, auditable investigation into an individual’s identity, employment history, financial probity, and criminal record. And like any thorough process, it comes with costs that go beyond a simple DBS fee.

Understanding the true BS7858 security screening cost is essential for accurate bidding, budgeting, and avoiding surprises.

This guide breaks down every element of the vetting process, from the base fees to the hidden costs that can double your bill if you’re not prepared.

What Is BS7858 and Why Does It Matter?

BS7858 is the British Standard for “screening individuals working in secure environments.” It’s not a legal requirement, but it is often a contractual necessity for security companies working in the following: 

• Critical national infrastructure (power stations, transport hubs) 
• Government and defence sites 
• High-value corporate security 
• Facilities management for sensitive clients 

The standard sets out a rigorous, multi-stage process that goes far beyond a basic DBS check. It verifies:

• Identity through multiple official documents
• A minimum of three to five years of employment history
• All gaps of 31 days or more, which must be explained and verified
• Financial probity (credit checks and court judgments)
• Criminal record (Enhanced DBS check)
• Professional qualifications and references

Because the process is so thorough, the BS7858 screening cost reflects the time, expertise, and third-party checks required to complete it properly.

BS7858 Security Vetting Cost: The Full Breakdown

The total vetting cost for BS7858 depends on several factors: the depth of checks required, whether you use an in-house team or outsource, and how many staff you’re vetting. Here’s a realistic breakdown.

1. Identity Verification

This involves checking multiple original documents (passport, driving licence, birth certificate, proof of address). While the document check itself is low-cost, the time required to collect, inspect, and record these details adds up. 

• Typical cost per applicant: £10-£25 (admin time) 

2. Employment and Activity History

The heart of BS7858. Vetters must contact previous employers, verify dates, and confirm reasons for leaving. Every employment gap of 31 days or more must be investigated and verified with independent evidence (bank statements, education records, etc.). 

• Typical cost per applicant: £40-£80 (dependent on number of employers and gaps) 

3. Financial Probity Check

This includes a credit check to identify county court judgments (CCJs) and insolvency history. The goal isn’t to assess wealth but to identify financial vulnerability that could pose a security risk. 

• Typical cost per applicant: £15-£30 (third-party credit check fee)

4. Criminal Record Check (Enhanced DBS)

An Enhanced DBS check is mandatory for BS7858 vetting. This includes a search of the Police National Computer and, if eligible, the Barred Lists.

• Typical cost: £49.50 – £69.90 (government fee) plus admin (£15-£25) = £65-£95

5. Reference Verification

Professional references from previous employers and character references must be obtained and verified.

• Typical cost per applicant: £10-£20 (admin time) 

6. Vetting Administration and File Management

The BS7858 standard requires meticulous documentation. Every check must be recorded, every discrepancy logged, and the final file must be audit-ready. This is where the BS7858 standard shows its teeth—it’s not enough to do the checks; you must prove you did them correctly.

• Typical cost per applicant: £20-£40 (file preparation, storage, audit trail)

7. Supervision and Quality Assurance

Vetting files should be reviewed by a competent person (often a security-vetted manager) to ensure compliance. This oversight adds cost but is essential for maintaining the standard. 

• Typical cost per applicant: £10-£25

Total BS7858 Screening Cost: Putting It Together

Here’s what a typical, fully compliant BS7858 vetting package looks like: 

This range reflects the variation in complexity. A straightforward candidate with a clean history and few employment gaps might cost £170-£200. A candidate with multiple employers, international periods, or name changes can push the cost toward £300+. 

Hidden Fees That Catch Businesses Out

The BS7858 cost isn’t just the sum of the checks. Here are the hidden fees that security companies often overlook.

1. Re-vetting Costs

BS7858 recommends periodic re-vetting (typically every 3-5 years). If you don’t factor this into your workforce planning, renewal costs become unexpected hits to your budget.

2. Failed or Incomplete Vetting

If a candidate drops out mid-process or fails to provide required documentation, the costs already incurred (checks, admin time) are non-recoverable. This risk multiplies when you’re vetting multiple candidates simultaneously.

3. Rush Fees

When a client needs immediate deployment and you don’t have vetted staff ready, you may need to pay premium rates to expedite checks—or worse, turn down the work.

4. In-House vs. Outsourced Vetting

Running vetting internally requires trained staff, software, and audit processes. While this can be cost-effective at scale, many companies underestimate the background check cost of maintaining compliance in-house. Outsourcing to a specialist provider like Smart Workforce shifts this burden to a fixed, predictable fee.

5. Document Replacement and Admin Overheads

Lost, expired, or incomplete identification documents delay the vetting process and add administrative costs. Requesting new passport photos, chasing missing paperwork, or resending verification requests all consume time that isn’t reflected in the base fee. For larger workforces, these small overheads accumulate quickly—often adding 10-15% to total vetting expenditure. 

How to Reduce Your BS7858 Vetting Costs

While BS7858 vetting is a necessary investment, you can manage costs strategically:

1. Vet in Batches

Instead of vetting one guard at a time, process cohorts. This spreads fixed admin and supervision costs across multiple applicants, reducing the per-person expense significantly.

2. Use Automated Vetting Software

Manual vetting is slow and labour-intensive. Automated platforms reduce admin time, track progress, and ensure nothing is missed—cutting per-applicant costs by 30-50% while improving accuracy.

3. RetainVetted Staff 

The cheapest vetting is the one you don’t need to repeat. Focus on retention strategies—competitive pay, fair scheduling, and career development—to avoid constant re-vetting cycles and the costs that come with high turnover.

4. Partner with a Specialist

Outsourcing to a dedicated vetting provider like Smart Workforce gives you predictable per-applicant pricing, built-in compliance, and no hidden fees. This eliminates the need for in-house vetting expertise and infrastructure.

5. Streamline Document Collection Early

Delays often start before the vetting process begins. Implement a standardised onboarding pack that collects all required documents—passport, proof of address, employment history—at the application stage. Proactive collection prevents last-minute chasing and keeps the process moving without costly interruptions. 

Conclusion

BS7858 security vetting is an essential investment for any security company operating in high-trust environments. The true BS7858 screening cost ranges from £170 to £315 per applicant, depending on complexity and whether you manage the process in-house or outsource.

Hidden fees—re-vetting, failed checks, rush charges—can significantly inflate costs if you’re not prepared. But with careful planning, automated tools, and strategic retention, you can turn vetting from a cost centre into a competitive advantage.

Because in the security industry, trust isn’t just earned—it’s verified.
