If you’re managing a building or estate in the UK, a security risk assessment is one of the most practical steps you can take to understand how well your site is protected. But for many property and facilities teams, the two biggest questions are: what does it involve? and how much does it cost?
This guide breaks it down in plain terms so you can understand what you’re paying for and why prices vary so much between projects.
What is a security risk assessment?
A security risk assessment is a structured review of a building or site to identify weaknesses, evaluate potential threats, and recommend improvements.
It looks at how likely security issues are and what impact they could have, then turns that into practical, prioritised actions.
Typical areas reviewed include:
- Building access points and entry control
- CCTV coverage and effectiveness
- Lighting and visibility around the site
- Reception, visitor and contractor procedures
- Perimeter security (gates, fences, barriers)
- Internal layouts and vulnerable areas
- Local crime patterns and environmental risks
The end result is usually a written report with clear recommendations.
What’s involved in the process?
While every consultant works slightly differently, a standard security risk assessment usually follows four stages.
- Initial briefing and background research
- Site visit and inspection
- Risk analysis
- Report and recommendations
How much does a security risk assessment cost in the UK?
Costs vary widely depending on the size and complexity of the site, as well as the depth of reporting required.
Typical price ranges:
- Small sites (offices, small retail units, single buildings): £500 – £1,500
- Medium sites (schools, multi-floor offices, larger commercial buildings): £1,500 – £5,000
- Large or complex sites (estates, hospitals, critical infrastructure, multiple buildings): £5,000 – £15,000+
Some consultants also charge a day rate, typically:
- £500 – £900 per day
A straightforward assessment might take 1–3 days, while more complex environments can take a week or more including analysis and reporting.
What affects the cost?
Several factors influence the final price of a security risk assessment:
Size and complexity of the site
Larger or multi-building sites naturally require more time to assess.
Level of detail required
A basic overview report will cost less than a detailed, compliance-style document.
Number of systems to review
CCTV, access control, alarms, and visitor systems all add to the scope.
Operational disruption
Some sites require out-of-hours visits or phased inspections.
Location and travel
Sites outside major cities or with multiple locations may increase costs.
Follow-on work
Some consultants include recommendations only, while others offer design support or implementation advice.
Is it worth the cost?
For most property and facilities teams, a security risk assessment is less about cost and more about avoiding expensive problems later.
A well-run assessment can help:
- Prevent theft, vandalism or unauthorised access
- Reduce insurance risks and claims
- Improve staff and visitor safety
- Avoid over-investing in unnecessary security systems
- Identify issues before they escalate into incidents
In many cases, the cost of an assessment is significantly lower than the cost of a single serious security incident.
Final thoughts
Security consultancy is not just a compliance exercise—it is a practical way of understanding how a building actually performs under real-world conditions and where improvements will make the most difference.
While costs in the UK can range from a few hundred to several thousand pounds depending on the size and complexity of the site, the real value lies in clarity: knowing where the genuine risks are, what needs attention first, and how to address them in a proportionate, cost-effective way.
For property and facilities teams, that insight often becomes the foundation of a more efficient, resilient and well-informed security strategy.
At Cognitious, we support UK property and facilities teams with practical, independent security advice tailored to real operational environments. From risk assessments and security audits through to design guidance and long-term strategy, we help organisations strengthen safety, improve resilience, and make confident, informed decisions about security across their sites.
