Winning security contracts comes down to one thing: giving the client confidence that you will not let them down. Everything in your tender — your method statement, your staffing plan, your compliance credentials, your pricing — is evidence for or against that single proposition.
Most security tenders are lost before the pricing page. Clients reading ten or fifteen submissions in an afternoon are looking for reasons to discard, not reasons to choose. Understanding what procurement decision-makers actually look at — and what causes tenders to be discarded — is the starting point for writing one that gets noticed.
Understanding What Procurement Teams Want
Security contract procurement in the UK ranges from informal conversations with a local retailer to multi-year framework agreements with local authorities, NHS trusts, and large commercial property portfolios. The complexity of the process scales with the contract value, but the core questions procurement teams are trying to answer remain consistent:
- Can you reliably fill every shift? Unfilled shifts are the number one operational failure that costs security companies contracts. Clients want evidence you have the bench depth, the scheduling processes, and the absence management systems to deliver continuity.
- Are your guards properly licensed and vetted? Every guard must hold a valid SIA licence for the role they’re performing. For higher-security sites, BS 7858 screening is often a minimum requirement. Clients increasingly ask for evidence of how you monitor ongoing licence validity — not just that guards were licensed at the time of hire.
- How do you demonstrate what your guards actually do? Incident logs, patrol records, occurrence books, and handover reports are the tangible evidence of your service. Clients who can access these in real time — rather than waiting for a monthly summary — have much greater confidence in the service they’re receiving.
- What happens when something goes wrong? Every client is thinking about their worst-case scenario. A clear escalation procedure, a named account manager, and a documented incident response process answer this question before it’s asked.
The Structure of a Winning Security Tender
Executive summary
Decision-makers often read the executive summary first and, if it doesn’t land, last. Keep it to one page. Lead with what you understand about the client’s specific requirements — not a generic description of your company. State clearly what you are offering and why you are the right choice. Avoid industry jargon and acronyms that procurement teams outside the security sector may not recognise.
Company overview and credentials
Your SIA Approved Contractor Scheme (ACS) status — if you hold it — should feature prominently. ACS accreditation is the primary quality signal that procurement teams in the public sector and large corporates use to pre-qualify security companies. If you don’t hold ACS status, address this directly: what quality standards do you operate to, and what accreditation are you working towards?
Include your public liability insurance limits, employer’s liability insurance, and any sector-specific certifications relevant to the contract (NSI, SSAIB, ISO 9001, etc.).
Method statement
The method statement is usually the longest and most important section. It should cover:
- Mobilisation plan: How quickly can you have fully vetted, licensed, and briefed officers on site? What is your vetting and onboarding process?
- Assignment instructions: How are site-specific instructions documented and communicated to guards? How are they updated when procedures change?
- Supervision and oversight: How often are officers supervised on site? How do you manage lone workers? What check-call or welfare monitoring processes are in place?
- Reporting: What reporting will the client receive? How is it delivered and how quickly after each shift?
- Absence management: How do you manage short-notice absences to ensure shifts are covered? What is your guaranteed response time?
- Compliance monitoring: How do you monitor ongoing SIA licence validity? What happens if a guard’s licence lapses?
Technology and evidence
A growing number of security contracts — particularly with local authorities, housing associations, and commercial property managers — require bidders to demonstrate how they use technology to evidence service delivery. This includes GPS-verified clock-in and clock-out, digital patrol records with NFC or QR checkpoint scanning, real-time incident reporting with timestamped entries, and client portal access to reports and logs.
If you can offer a client portal where their facilities manager can log in at any time and see current deployment status, recent incident reports, and patrol records, that is a significant differentiator. Many security companies still rely on emailed spreadsheets and paper occurrence books.
Pricing
Security contract pricing in the UK is typically submitted as an hourly rate per guard, with separate rates for different shift types (days, nights, weekends, bank holidays) and different licence activities (Security Guard, Door Supervisor, CCTV Operator, etc.).
Procurement teams are not always looking for the cheapest submission — particularly in public sector and regulated environments where an abnormally low bid raises questions about compliance and living wage obligations. The British Security Industry Association (BSIA) publishes guidance on indicative rates that factor in living wage obligations, SIA licence costs, training, and employer on-costs. Use this as a floor, not a target.
Itemise your pricing clearly. A breakdown showing how your hourly rate is composed — direct labour, employer’s NI, holiday pay, equipment, supervision, and margin — demonstrates transparency and makes your tender easier to evaluate fairly.
Operational Evidence That Wins Contracts
The shift that has happened in security procurement over the last five years is the move from promises to evidence. Ten years ago, a polished brochure and a confident presentation won contracts. Today, serious clients want to see the data behind the service: GPS records showing guards were where they said they were, incident reports filed within minutes rather than days, patrol logs with checkpoint scan times rather than handwritten notes.
This is partly driven by high-profile failures of security companies that looked credible on paper but couldn’t deliver operationally. It is also driven by a wider trend towards data-driven procurement across both public and private sectors.
The practical implication is that the operational systems you run every day are also your sales assets. If you can pull up a clean compliance dashboard showing every guard’s licence status, a patrol report with GPS-verified checkpoint scans, and a client portal your prospective client can demo on the spot, your tender writes itself.
After Submission: The Clarification Stage
Most formal tender processes include a clarification stage before shortlisting, where procurement teams ask follow-up questions about specific elements of submissions. This is an opportunity, not a threat. Prepare for questions about:
- How you handle key worker absence at short notice
- Your process for investigating and reporting incidents to the client
- How you manage subcontracted labour (if applicable)
- Your approach to staff retention and guard turnover
If you advance to a presentation or site visit, bring evidence rather than slides. A live demonstration of your guard management platform, showing real (anonymised) data from a current contract, is more persuasive than a PowerPoint deck about how professional your operation is.
Building a Pipeline of Tender Opportunities
Most public sector contract opportunities in the UK above £25,000 must be advertised on Find a Tender Service (formerly Contracts Finder). Sign up for alerts in the security services category and review new opportunities weekly. For NHS, local authority, and central government frameworks, pre-qualification questionnaires (PQQs) are often the first step — keeping your company credentials, insurance certificates, and accreditation documents current makes this stage faster.
Private sector opportunities are harder to find systematically but can be developed through industry relationships, professional body membership (BSIA, ACS), and direct outreach to facilities managers and commercial property portfolios in your target geography.
The companies that win the most security contracts are those whose operations are tight enough to be evidenced clearly and whose proposals are specific enough to feel genuinely tailored. Generic submissions lose. Evidence wins.
