When it comes to protecting people, property and assets, hiring the right security company is one of the most important decisions a manager can make. Whether you’re overseeing a large construction site, managing a commercial property, or in charge of safety for a retail business, security is never something to leave to chance.
But with so many providers offering a wide range of services, such as static security guards, mobile patrols, CCTV and canine units, how do you know who to trust? What should you be looking for? And what are the warning signs that a company might not be up to scratch?
This guide covers the top questions you should ask before hiring a security company. It’s designed to help you compare providers with confidence, make an informed decision and get the protection your site needs.
Security is about more than just putting someone in a high-vis jacket at the front gate. A reliable security provider becomes an extension of your team. They’re on your site, interacting with your staff and visitors and often dealing with high-pressure or sensitive situations.
A good company will reduce risk, deter criminal activity and help you meet your legal and insurance obligations. A bad one could lead to missed incidents, reputational damage or even legal trouble.
That’s why it pays to dig deeper before signing a contract. Asking the right questions at the start helps you avoid problems later on.
Below we have outlined some of the key questions to ask any potential security provider to ensure you’re getting the quality of service your business deserves.
Any security guard working in the UK must hold a valid SIA (Security Industry Authority) licence. It’s non-negotiable. But beyond that, look at what other accreditations the company holds. Are they a member of any recognised trade bodies like the ACS (Approved Contractor Scheme)? Do they have ISO certifications for quality management or health and safety?
Accreditations show that a company meets recognised industry standards and is regularly audited. It’s a good sign that they take their responsibilities seriously.
You need to know who is coming onto your site. Ask about the company’s recruitment process. Do they carry out full background checks? How do they verify references and work history? Are guards trained before they’re deployed?
Vetting is especially important if guards will have access to sensitive areas or be working in close contact with the public. A trusted provider should be happy to explain how they screen staff and how often this is reviewed.
Security needs vary across sectors. A company that mainly works in nightlife venues may not be the best fit for a logistics site or residential block.
Ask about their track record in your industry. Have they worked with similar clients before? Can they describe specific challenges they’ve dealt with on comparable sites?
Relevant experience means they’re more likely to understand your risks, your working environment and how to approach security in a way that works for you.
Any company can claim to offer the best security guard services. Real feedback from current or past clients is what sets genuine providers apart.
Ask for recent testimonials or case studies from similar businesses. Look for detail about what was delivered, what problems were solved and how the client felt about the service.
Positive, specific feedback gives you insight into the company’s reliability and customer relationships. Be cautious if a company can’t or won’t provide references.
Incidents don’t happen to a schedule. Whether it’s an alarm activation, break-in or safety concern, a fast response can make all the difference.
Ask how quickly the company can respond to different types of incidents. Do they offer 24/7 support? What happens if a guard doesn’t show up? Is there a control room that monitors your site around the clock?
A good provider should have robust procedures in place for dealing with emergencies, and they should be able to explain them clearly.
Visibility is a key part of modern security services. Ask how the company keeps you informed.
Do they provide shift reports or incident logs? Is there a digital system that lets you view guard activity in real-time? Can you access reports remotely?
Strong reporting systems help you stay in control and make it easier to spot trends or potential issues. They’re also useful for audit trails or compliance checks.
This is a good question to ask toward the end of your search. You’ve heard what they offer, you’ve seen the accreditations, now it’s time to find out what sets them apart.
Is it the level of customer service? Their investment in training or tech? Their rapid deployment capability? A strong answer here will show the company understands your priorities and is confident in its offer.
While you’re asking questions, keep an eye out for red flags. These might include:
A company that cuts corners before you’ve even signed a contract is unlikely to meet your expectations when the service begins.
Hiring a security company is a big decision. It’s about protecting your site, your people and your reputation. Asking the right questions can help you identify the providers who genuinely care about doing the job properly and avoid those who are just ticking boxes.
From vetting and licences to response times and real-world experience, each answer gives you more confidence that you’re making the right call.
