With hundreds of security companies operating across Essex, London and the wider South East, selecting the right provider is one of the most important procurement decisions a business can make. Get it right and you have reliable, professional protection that gives you genuine peace of mind. Get it wrong and you could be paying for inadequate coverage, unvetted staff, or a provider that disappears when you need them most. Here are the ten questions that separate professional security companies from the rest.
This is non-negotiable. Every officer performing a licensable security role — manned guarding, door supervision, close protection — must hold a valid SIA licence. Any company that cannot confirm this, or that hedges with "most of our staff are licensed," should be immediately disqualified. Ask for confirmation in writing and verify licences through the SIA's public licence checker before deployment begins.
The British Standard BS 7858 defines the screening process for security personnel. It requires a minimum five-year background check covering employment history, address history, criminal records (enhanced DBS) and financial sanctions checks. A company that complies with BS 7858 has done the work to ensure its staff are genuinely trustworthy. Companies that cannot confirm compliance should be viewed with caution.
The SIA Approved Contractor Scheme (ACS) is an independently audited quality standard for security companies. ACS-approved companies have demonstrated compliance with industry standards in areas including governance, staff management, health and safety, and service delivery. While ACS approval is not mandatory, it is a meaningful indicator of a company's commitment to quality.
Noble Shield commitment: Every Noble Shield officer is SIA-licensed and vetted to BS 7858. We are fully committed to compliance with all applicable UK legal and industry standards, and our clients are welcome to verify this at any time.
Any reputable security company will hold at minimum:
Always request a copy of the current insurance certificate and verify it is genuine. Insurance gaps are a red flag for a company's overall professionalism.
Established security companies should be able to commit to documented response times for emergency situations — whether that means additional staffing during an incident, emergency keyholding response or management support. Ask for their emergency escalation procedure in writing. A company that cannot answer this question clearly does not have a robust operational structure.
Quality control is what separates good security from unreliable security. Ask specifically:
A good security company will have clear, documented answers to all of these questions.
References from current or recent clients in a similar sector to yours are invaluable. A reputable company will be happy to provide references. When you speak to referees, ask not just whether they are satisfied overall, but specifically about how the company handled incidents, staffing gaps and complaints. The response to problems is often more revealing than the normal service.
Be very cautious of long minimum contract periods, automatic renewal clauses, and punitive exit penalties. The security industry has a poor reputation in this area, with some companies locking clients into multi-year contracts with very difficult exit routes. Look for:
Noble Shield offers flexible arrangements with no minimum contract requirement — we believe our service should earn continued loyalty, not be contractually enforced.
Security requirements differ significantly between a retail store, a construction site, a licensed venue and a corporate office. A security company that specialises in or has significant experience of your sector will understand the specific risks, regulatory requirements and operational constraints that matter to you. Ask for examples of similar clients they have worked with and what specific measures they implemented.
A security company with officers and management based in or near your area will be able to respond more quickly to emergencies, provide local knowledge that improves their effectiveness, and give you access to senior personnel when you need them. National companies with centralised management can struggle to provide the agile, responsive service that many businesses require.
Price matters — but it should not be the primary criterion. Security is one area where the cheapest option frequently proves the most expensive in the long run. A security failure — a theft, an assault on a staff member, a compliance breach — costs far more than the premium of a quality security provider. Evaluate on the full picture: licensing, vetting, insurance, references, flexibility and responsiveness.
