Who Needs BS 10119? A Complete Guide for UK Security
If you work in the UK security or events industry, you have probably heard about BS 10119. The real question is simple: does your business need to follow the standard? The answer depends on three key factors: what your business does, who you work with, and how you supply or use labour. Some companies may need to meet specific requirements, while others may only need to understand how the standard affects their contracts and operations. This guide explains which businesses BS 10119 applies to, what responsibilities they may have, and how to determine where your company stands.

What Is BS 10119, in Simple Terms?

BS 10119 is an official British Standard, published by BSI. It covers how businesses manage bought-in labour supplied to the security and events sectors.

In simple terms, it applies to two types of companies. First, it applies to companies that supply extra staff. Second, it applies to companies that take on extra staff from someone else. The standard focuses on how businesses hire, screen, train, and manage the people they deploy.

Therefore, BS 10119 is not just a paperwork exercise. It sets a clear benchmark for trust between suppliers, buyers, and clients across the industry. Because contracts often move between multiple companies, this standard gives everyone a shared reference point for accountability.

So, before going further, let’s answer the main question everyone asks.

New BSI Standard: BS 10119 for UK Security

Who Needs BS 10119?

Not every security business needs to act on BS 10119 immediately. However, several types of businesses should pay close attention:

  • Businesses that supply staff to other security or event companies
  • Businesses that use extra staff from another supplier
  • Principal contractors overseeing security operations
  • Companies bidding for tenders that specifically request it

If your business fits any of these categories, this standard directly affects how you work. Even so, the level of impact varies. A labour supplier faces different obligations than a company that occasionally borrows staff for a single event. That said, both sides carry some responsibility once bought-in labour enters the picture.

Labour Providers: Do You Need It?

If your business supplies staff to security or event companies, BS 10119 applies directly to you.

Who Counts as a Labour Provider?

This category includes businesses supplying:

  • SIA-licensed security officers
  • Door supervisors
  • Event security personnel
  • Crowd-management staff
  • CCTV operators
  • Mobile patrol and key holding staff

Your Responsibilities as a Supplier

As a labour provider, you are responsible for proving your workers are properly screened, trained, and legally employed. Without that proof, clients may hesitate to work with you, especially on larger contracts. As a result, compliance often becomes a deciding factor when clients choose between suppliers.

Companies Using Extra Security Staff: Are You Covered?

Here’s something many business owners miss: BS 10119 applies not only to the company supplying labour. It also matters to the company using that labour. If you bring in extra guards from another business to fulfil a contract, you still carry responsibility for the outcome. If something goes wrong, like an unlicensed guard on site, your reputation takes the hit, even if your supplier made the mistake.

Consequently, buyers of labour need their own checklist before accepting bought-in staff:

  • Confirm the supplier’s screening and vetting process
  • Request proof of SIA licences and training records
  • Check the supplier’s compliance history with past clients
  • Review contracts for clear accountability terms

So, if you regularly use bought-in labour, checking your supplier’s compliance becomes essential, not optional.

Principal Contractors: What Should You Check?

If you oversee security operations as a principal contractor, BS 10119 gives you a clear way to protect yourself. Before accepting any security company onto your site, ask these questions:

  • Does this business supply or use bought-in labour?
  • Can they provide evidence of proper screening and training?
  • Do their labour providers meet BS 10119 requirements?

Asking these questions upfront prevents costly surprises later, especially if something goes wrong mid-contract.

Businesses Bidding for Tenders: Why It Matters

If you regularly bid for tenders, it might already affect your chances of winning contracts, even if you have not noticed it yet. The standard is becoming an important consideration for businesses that provide labour to the security and events sectors. If a tender specifically asks for BS 10119, meeting that requirement can become an essential part of your bid.

1. Tender Requirements Can Include BS 10119

Some tender opportunities may ask suppliers to demonstrate compliance with BS 10119. If it is listed as a requirement, you need to understand exactly what the buyer expects before submitting your bid.

2. It Can Affect Your Eligibility

Tender documents often contain specific requirements that suppliers must meet. If BS 10119 is included as a mandatory requirement, not having the relevant certification or evidence could affect your eligibility for that opportunity.

3. Larger Clients May Expect Stronger Standards

Large organisations often look for suppliers with clear systems, processes and evidence of good practice. Demonstrating alignment with BS 10119 can help show that your business has structured processes for supplying labour within the relevant sectors.

4. Government and Commercial Contracts

For businesses targeting government, public-sector or larger commercial contracts, keeping up with relevant standards is important. Requirements can vary from one tender to another, so always check the individual tender specification rather than assuming BS 10119 is required everywhere.

5. Prepare Before the Tender Opens

Don’t wait until the deadline is approaching to check your compliance. Review your current processes, documentation, and evidence early. If this standard is relevant to your target contracts, preparing in advance can make the tender process much smoother.

Key takeaway: BS 10119 may not be a legal requirement for every business, but tender-specific requirements can make it commercially important. Always check what each buyer requires before submitting your bid.

Who Doesn’t Need BS 10119 Yet?

Not every security business needs to rush into this immediately:

  • Businesses that never supply or use bought-in labour
  • Small operations relying entirely on their own permanent staff
  • Companies with no plans to bid for tenders requiring it

That said, even these businesses should stay informed. Client expectations shift quickly in this industry. Today’s optional standard often becomes tomorrow’s requirement.

How to Know If Your Business Qualifies

So, how do you actually figure out where your business stands? Start by asking yourself these questions:

  • Do we ever supply staff to another security or event business?
  • Do we ever bring in extra staff from another supplier?
  • Have any of our clients or tenders mentioned BS 10119?
  • Do we want to strengthen our credibility with larger clients?

If you answered yes to any of these, explore BS 10119 properly. Don’t wait until a client asks and catches you unprepared.

Frequently Asked Questions

1. Does every security company need BS 10119?

No, not immediately. It mainly applies to businesses that supply or use bought-in labour regularly. Small operations with only permanent staff can stay informed instead.

2. Do I need BS 10119 if I only supply staff occasionally?

Yes, it’s still worth checking. Even occasional labour supply can affect your compliance status. Clients often expect proof regardless of frequency.

3. Is BS 10119 only for labour providers, or does it affect buyers too?

It affects both sides equally. Companies using bought-in staff share responsibility for compliance. Ignoring this can still damage your reputation.

4. Can small security businesses apply for BS 10119?

Yes, business size doesn’t restrict eligibility. What matters is whether you supply or use bought-in labour. Even small teams can meet the requirements.

5. How do I know if my business needs BS 10119?

Check whether you supply or use extra staff. Also check if any tenders you bid for mention BS 10119. These two factors usually decide it.

Conclusion

BS 10119 is becoming an important consideration for UK security and events businesses that supply or use bought-in labour. However, it does not automatically apply to every company. Your responsibilities depend on how your business operates, who you work with, and what your clients or tenders require.

The best approach is to understand your position early and keep your screening, documentation, and labour processes in order. This can help you avoid compliance gaps and respond confidently to client requirements.
