If you are comparing providers, one question usually comes first: how much does a cyber security consultancy cost in the UK? The short answer is that cost varies widely based on your business, your existing security maturity, the type of services you need, and whether you work with independent consultants or a larger consultancy.
This guide is for UK businesses that want practical budgeting advice before they invest in cyber security support. It explains common pricing models, typical UK ranges, the main factors that affect cyber security costs, and the true cost of choosing the wrong scope.
At Global Security Consultancy, we work with UK businesses to define the right level of cyber security investment based on risk, compliance requirements, and business objectives. This guide reflects real-world pricing across engagements including risk assessments, Virtual CISO advisory, and Cyber Essentials consultancy.
Overview Of Cyber Security Costs And Services
Most cyber security services fall into a few broad groups. These include assessments, compliance support, incident response planning, penetration testing, cloud security, endpoint hardening, and managed detection and response advisory. Some providers also support employee training, email protection, security policies, and cyber risk management.
The most common pricing models are:
-
Hourly fees
-
Project-based pricing
-
Fixed-fee engagements
-
Monthly retainers
-
Advisory support models
For most businesses, size is one of the first factors that shapes the budget. Small businesses often need a narrower scope and a more cost-effective plan. Medium businesses and large enterprises usually face more complex systems, more users, more compliance pressure, and broader infrastructure, which pushes costs upwards.
Typical Pricing Models For Cyber Security Services
Hourly Pricing
Hourly pricing is common in cyber security consulting, especially for early advisory work, short audits, or remediation support. In the UK market, independent consultants often charge between £70 and £250 per hour, while larger security firms may charge £150 to £500+ per hour.
As a rough guide:
-
Junior consultants: £50 to £80 per hour
-
Mid-level consultants: £80 to £200 per hour
-
Senior specialists: £200 to £500+ per hour
These hourly rates depend on experience, sector knowledge, and whether the consultant brings specialised expertise in areas such as cloud security, risk management, or incident response.
Project-Based Pricing
Project-based pricing suits clearly defined work. This might include penetration testing, system audits, ISO gap analysis, a cyber security risk assessment, or a one-off cloud security review. A fixed fee works well when the deliverables, timescale, and responsibilities are clear. It gives your business more certainty on cost and helps avoid scope drift.
Monthly Retainers
For ongoing support, many providers offer monthly retainers. These are common for businesses that need regular strategic advice without building an in-house security leadership team. For small and medium businesses, retained cyber security consultancy support can range from £500 to £2,000+ per month, depending on the level of guidance, reporting, and support included. Retainers are particularly useful when your business needs ongoing governance, recurring compliance guidance, regular risk reviews, or access to Virtual CISO services.
When Value-Based Pricing Makes Sense
Some consultancies use value-based pricing where the work protects high-revenue operations, regulated environments, or high-risk systems. This model can make sense where the engagement delivers significant value, such as helping avoid downtime, improving customer trust, or accelerating certification.
It is less common than hourly or project-based pricing, but it can work well when the outcome matters more than the time spent.
Cost Drivers: Business Size, Sector And Existing Security Controls
Business Size
Business size has a major effect on cyber security costs. Smaller companies usually have fewer devices, fewer users, and fewer locations. That makes scoping easier.
By contrast, medium-sized businesses and larger organisations often have more endpoints, more cloud workloads, and more complex infrastructure.
As a result:
-
Small businesses usually pay less for assessments and advisory support
-
Medium businesses often need broader coverage and more formal reporting
-
Large enterprises may need deeper governance, more evidence gathering, and more frequent reviews
Sector And Compliance Requirements
Sector also matters. Financial services, healthcare, legal, technology, and critical supply chain organisations often pay higher costs because their compliance requirements are stricter.
If your business handles sensitive data, payment environments, or regulated records, your provider may need deeper testing, more documentation, and more frequent reviews. Frameworks such as Cyber Essentials, ISO 27001, GDPR, and PCI DSS can all affect the scope and cost of an engagement.
Location: London Vs Regional Providers
Location can affect pricing. London-based consultancies often charge 15% to 30% more than regional providers. That does not always mean better results.
Many UK businesses outside London can access expert guidance from regional specialists at a lower cost. Global Security Consultancy supports organisations across South Yorkshire, including Sheffield businesses, Doncaster organisations, Rotherham businesses, and Barnsley organisations.
Existing Security Controls And Maturity
Your existing security controls also shape the final quote. If your business already has multi-factor authentication, endpoint protection, patching, backup routines, and basic monitoring in place, the work may be quicker and more affordable.
If your current state is weak, the consultancy may need to help rebuild core controls, governance, and processes from the ground up.
That is why it is wise to assess your cyber maturity before you invest heavily. A structured review can reveal how much work is really needed.
Detection And Response: Typical Pricing
Detection and response pricing varies depending on hours of coverage, tooling, escalation terms, and whether your organisation needs advisory oversight or fully managed services.
A baseline package for an SME may include alert monitoring, triage, endpoint telemetry, and limited incident response advice. These services often start from the low thousands annually.
Typical monthly ranges may include:
-
Entry-level SME monitoring: £500 to £1,500 per month
-
Mid-range managed monitoring: £1,500 to £5,000 per month
-
Broader 24/7 managed detection and response: £5,000+ per month
If your business is worried about cyber attacks, an incident response retainer can provide named contacts, faster mobilisation, and agreed escalation routes if something goes wrong.
Cloud Security: Cost Factors And Packages
Cloud security pricing depends on the number of platforms, identities, workloads, and integrations in scope. A small Microsoft 365 review will cost far less than a multi-platform AWS, Azure, and SaaS estate.
Typical examples include:
-
Basic cloud security assessment: £1,500 to £5,000
-
Broader tenant and configuration review: £5,000 to £12,000
-
Ongoing cloud workload protection and monitoring: monthly cost based on users, assets, and tooling
Cloud services become more expensive to secure when your business uses several platforms, complex permissions, or hybrid in-house and hosted systems.
Breakdown Of Common Cyber Security Services And Costs
Penetration Testing
Penetration testing is one of the most requested cyber security services in the UK. Typical ranges start at around £4,000 for a tightly scoped test and can rise to £20,000+ for broader or specialist work.
Examples include:
-
External penetration testing: £4,000 to £8,000
-
Web application penetration testing: £5,000 to £15,000
-
Internal or hybrid tests: £6,000 to £20,000+
Specialist testers may charge £1,000 to £2,500+ per day.
Vulnerability scanning is usually cheaper than penetration testing and often works well as a recurring service. Pricing may range from a few hundred pounds per month for smaller estates to several thousand for larger ones. Attack surface management platforms are often priced monthly based on assets, domains, and IP addresses.
Training And Phishing Simulation
Employee training is often overlooked, yet it remains one of the most cost-effective controls. Awareness sessions, phishing simulations, and policy refreshers can be priced per user, per campaign, or as part of a wider package. For many UK businesses, this is a practical way to reduce cyber threats without a large capital budget.
Endpoint And Identity Controls
Managed endpoint protection, email filtering, and multi-factor authentication rollout can be sold as one-off projects or recurring support services.
These controls are especially useful for smaller companies that do not have a mature in-house team.
Cyber Essentials And Compliance Cost Considerations
If your business needs Cyber Essentials certification support, budget for both the certification fee and any remediation work required before submission.
The certification itself is relatively affordable, but the wider cost can increase if your current controls are weak. For ISO 27001, implementation support in the UK typically costs £15,000 to £30,000. That may include readiness reviews, policy development, risk workshops, and documentation support. Audit fees are often separate (as the implementer can't be the auditor) so include them in your estimates from the start.
Where compliance matters, always check whether the proposal includes:
-
Readiness assessment
-
Gap analysis
-
Documentation support
-
Internal audit support
-
External audit fees
-
Ongoing maintenance
Solo Consultants Vs Security Firms
A major pricing question is whether to use independent consultants or a larger consultancy. If you are unsure what level of support you need, it can help to understand what a cyber security consultancy does before comparing quotes.
Solo advisers can be more flexible and often more cost effective. They may offer tailored support, direct accountability, and lower overheads. For small businesses and smaller companies, this can be attractive. However, there can be trade-offs. A solo consultant may have limited availability, may support several clients at once, and may not offer the same breadth of services as a firm.
Larger firms usually offer wider security consulting capability, formal escalation paths, broader resources, and more cover across services such as incident response, cloud security, risk assessment, and compliance support. The downside is higher costs and sometimes less direct accountability. Responsibility may be shared across teams rather than resting with one named expert.
Expertise, Accountability And Liability
This is where the choice becomes practical:
-
Need one trusted adviser with direct ownership? Consider an independent consultant.
-
Need broader capability, specialist resources, or stronger contractual backing? A firm may fit better.
-
Need board-level strategic oversight? Consider Virtual CISO advisory.
For many business owners, the best answer is not the cheapest provider. It is the one that matches your risk, timeline, and internal capability.
When comparing proposals, watch for hidden costs. These often include:
-
Software licence fees
-
Subscription and renewal charges
-
Travel or onsite day expenses
-
Additional reporting fees
-
Emergency out-of-hours support
-
Scope changes after discovery work
There are also indirect costs that many businesses miss. If a breach happens, the true cost can include downtime, lost productivity, reputational damage, legal advice, customer notification, and rising insurance premiums. That is why cyber security costs should be weighed against the cost of recovery from cyber attacks. Good consultancy support should create long-term security outcomes, not just a short-term report.
The 80/20 rule in cyber security means that a relatively small set of well-chosen controls can reduce a large share of risk.
For most businesses, that means prioritising:
-
Multi-factor authentication
-
Patch management
-
Endpoint protection
-
Secure backups
-
Email filtering
-
Least privilege
-
Staff awareness
-
Basic monitoring
Before spending tens of thousands on advanced tools, many UK businesses should first fix these core gaps. That is often the most cost-effective route.
How Much Should A Consultant Charge In The UK?
If you are asking, “How much should I charge as a consultant in the UK?”, the answer depends on experience, specialism, and delivery model.
Typical benchmarks are:
-
Junior consultants: £50 to £80 per hour
-
Independent mid-level consultants: £70 to £250 per hour
-
Senior specialists: £200 to £500+ per hour
-
Security firms: £150 to £500+ per hour
If the work is high risk, urgent, or highly specialised, day rates can rise further. London rates may also be higher than regional benchmarks.
How Much Does A Cyber Security Consultant Make In The UK?
A cyber security consultant in the UK can earn anything from a modest starting salary to a strong senior package, depending on skill set and sector.
Salaried consultants often vary by region and employer, while contractors and specialists can command more through day rates. Experienced consultants with deep specialised knowledge in cloud security, incident response, compliance, or penetration testing tend to sit at the higher end of the market.
