How to Choose a Security Company in the UK

I have been running a security company in the UK since 2016. In that time I have spoken to hundreds of businesses who came to us after a bad experience with a previous provider. The story is almost always the same. They chose on price, signed a contract, and found out months later that what turned up on site had nothing to do with what they were sold. I am writing this because those conversations happen every week and most of them could have been avoided with a few straightforward questions asked before anything was signed.

Many businesses searching for how to choose a security company in the UK focus on price first, but experience shows that vetting standards, officer quality and contract management are usually more important.

The Difference Between SIA Licensed and SIA Approved

Most businesses know that security guards need an SIA licence to work legally in the UK. What most do not know is that the licence belongs to the individual, not the company. Any business can put SIA licensed guards on your site. That tells you nothing about how the company operates, how it vets its staff, or whether it will still be managing your contract properly six months from now.

SIA Approved Contractor status is a completely different thing. It means the Security Industry Authority has assessed the company itself against a defined set of standards. Management practices, vetting procedures, training quality, operational processes. The regulator has checked the business, not just the people it employs. When you are comparing providers, asking whether they hold SIA Approved Contractor status is one of the most useful questions you can ask.

Our manned guarding services are delivered by directly employed, SIA licensed officers who are briefed on your site before their first shift.

Are Your Officers Directly Employed or from an Agency

This is the question most businesses never think to ask, and it is one of the most important ones on this list.

A lot of security companies in the UK do not directly employ the officers they send to your site. They pull from staffing agencies, sometimes the morning the shift starts. The officer who shows up has never been briefed on your site, may not know your account manager and may not have been vetted to the standard you were quoted.

At USSG every officer we deploy is directly employed by us. No subcontractors, no agencies. Before anyone goes to a new site they go through BS 7858 vetting, which covers employment history going back five years, a criminal record check and full identity verification. We carry out that vetting ourselves.

Ask any provider you are considering: are your officers on your payroll or do you use agencies? If they cannot give you a straight answer, that is your answer.

We also offer key holding and alarm response services delivered by the same directly employed, vetted officers.

What BS 7858 Actually Involves

BS 7858 is the British Standard for vetting people working in security environments. Most security companies mention it. Fewer apply it properly.

A genuine BS 7858 process covers five years of employment history with gaps explained and verified, a Disclosure and Barring Service check, identity verification against original documents and a financial probity check. It takes time and it costs money to do it properly. There are shortcuts that some providers take without telling their clients, and there is no easy way to spot them from the outside unless you know what to ask.

If a provider cannot walk you through their vetting process in detail, that is worth knowing before you commit to a contract.

Martyn’s Law and What It Means for Your Business

Martyn’s Law, formally the Terrorism (Protection of Premises) Act 2025, is now in force across the UK. It places legal obligations on venues and public spaces with a capacity of 200 or more people to put proportionate counter-terrorism security measures in place and register with the SIA.

For businesses in hospitality, retail, events and commercial property this means reviewing existing security arrangements with a qualified provider. Working with an SIA Approved Contractor is the most straightforward route to making sure what you put in place meets the requirements of the Act.

If your premises fall within the scope of Martyn’s Law, our waking watch and fire safety services can help you meet your compliance obligations.

How to Choose a Security Company in the UK Without Making Expensive Mistakes

After nearly ten years of running contracts across the UK, these are the questions that tell you most about a provider before you commit to anything.

Do you hold SIA Approved Contractor status and when was it last renewed?

Are your officers directly employed by your company or sourced through agencies?

Can you walk me through your BS 7858 vetting process?

Who is my named account contact and how do I reach them at three in the morning if something happens?

Can you show me a sample of the shift and patrol reports your officers provide?

A good security company will answer all five without hesitation. Vague answers to any of them tells you something worth knowing.

What Good Account Management Actually Looks Like

This is the area where most security companies fall down, and it is the one that causes the most frustration for clients.

Good account management means one named person who knows your site, knows your team and can be reached any time something needs dealing with. Not a call centre that logs a ticket. Not a duty manager who has never visited your premises. One person who picks up the phone.

It also means proactive communication. If there was an incident on your site last night, you should not be finding out about it when you arrive in the morning. You should already have a full written report waiting for you. If there is a problem with resourcing your contract, your account manager should be calling you with a solution before the shift starts, not after it has been left uncovered.

Ask any provider you are considering: who is my named account contact and how do I reach them at three in the morning? If the answer involves a call centre or an out-of-hours team you have never spoken to, that is worth factoring into your decision.

How to Check a Security Company Before You Commit

There are a few things you can do before signing anything that will tell you a great deal about how a provider operates.

Ask for references from clients in a similar sector to yours and actually call them. Do not just read the testimonials on the website. Ask the reference contact directly: did the officers show up consistently, did the reporting arrive when it should, and how did the company handle it when something went wrong?

Check their SIA Approved Contractor status on the SIA website directly. The register is public and searchable. A company claiming ACS status that does not appear on the register has a problem you should know about before you hand them a contract.

Ask to see a sample shift report or patrol report. The quality of that document tells you a lot about the operational standards of the company. Vague, templated reports with no specific observations suggest officers are not actually carrying out the checks they are supposed to.

Finally, ask how they handle sickness cover. Every security company will occasionally have an officer call in sick. What matters is whether they have a reliable process for covering that shift without it becoming your problem to manage.

Security Company UK – Getting the Right Cover for Your Sector

Different sectors carry different security risks and a provider with genuine experience in your sector will deliver better results than one applying a generic approach.

Retail environments need officers who understand loss prevention, can de-escalate difficult customer situations professionally and know how to manage the balance between security presence and customer experience. Our security services cover retail, commercial, construction and residential environments across the UK.

Commercial office buildings need officers who can manage visitor access control professionally, handle out-of-hours security without disrupting building operations, and communicate clearly with facilities management teams.

Construction sites need officers with genuine site experience who understand CDM obligations, can manage subcontractor access properly and know what to do when something happens at two in the morning on an active build.

The right security company UK businesses in any sector should be looking for is one that understands your specific environment and can demonstrate real experience working in it.

What Proper Security Cover Looks Like Across the UK

A security company UK businesses can rely on will show up consistently, communicate clearly and deal with problems before they become incidents. That requires the right staffing model, proper vetting, real account management and the operational structure to back it up.
