How Much Does a Cybersecurity Consultant Cost in the UK?

Cybersecurity consulting rates in the UK vary significantly based on the type of work, the consultant's experience, and the engagement model. Here's what you can expect to pay in 2026:

These rates reflect independent consultants and specialist consultancies. Large firms (Big Four, global SIs) typically charge 30–50% more due to brand premium and overhead.

Several factors determine what you'll actually pay:

1. Specialism
General security advice costs less than niche expertise. Penetration testing, incident response, and compliance consultancy (especially for regulated industries like financial services) command premium rates because they require specific certifications and deep experience.

2. Urgency
Need someone next week for a compliance deadline? Expect to pay 20–50% more than standard rates. Emergency incident response — where a consultant drops everything to contain a live breach — can cost 2–3x normal rates.

3. Engagement model
Hourly billing gives flexibility but is the most expensive per-hour. Retainer models (monthly blocks of hours) typically offer 15–30% savings. Fixed-price projects work well for defined scope (like a Cyber Essentials assessment) but require clear requirements upfront.

4. Location and delivery
Remote consulting is typically cheaper than on-site. London-based consultants often charge 10–20% more than those elsewhere in the UK, though this gap has narrowed since 2020.

5. Firm vs independent
Independent consultants and boutique firms (like CBS) offer senior expertise at lower rates than Big Four or large SIs, because you're not paying for a graduate bench, Canary Wharf offices, or global overhead.

Hourly / day rate
Best for: ad-hoc advice, short assessments, second opinions. You pay for what you use but rates are highest.

Retainer
Best for: ongoing advisory, regular security reviews, virtual CISO services. You commit to a monthly block of hours at a discounted rate. Typical retainers run 5–20 hours per month.

Fixed-price project
Best for: defined deliverables like pen tests, compliance assessments, or certification projects. Price is agreed upfront — good for budgeting but requires clear scope.

Outcome-based
Rare in cybersecurity but growing. The consultant is paid based on achieving specific outcomes (e.g., achieving Cyber Essentials certification). Aligns incentives but harder to structure.

• Define your scope clearly — vague briefs lead to scope creep and higher costs
• Consider retainers — if you need regular support, a retainer saves 15–30% vs hourly
• Look beyond the Big Four — boutique consultancies deliver the same (often better) expertise at 30–50% less
• Check credentials — CREST, CHECK, CISSP, CISM certifications indicate genuine expertise
• Ask about included extras — some consultancies include travel, reports, and follow-up calls in their rates; others charge separately
• Start with a discovery call — a good consultant will tell you honestly whether you need them, and scope the work properly before committing

At CBS, we believe in straightforward pricing with no surprises:

• Discovery Call: £120 for the first hour — an introductory rate to understand your challenge and recommend next steps
• Retained Advisory: £1,500 for a 10-hour block (effective rate £150/hour) — our best value option, saving £1,000 vs standard hourly rates
• Full Engagement: £350/hour — includes face-to-face meetings, UK travel, written reports, stakeholder presentations, and security assessments

UK travel is included on Full Engagement — no mileage, accommodation, or expense charges within the UK. You pay for expertise, not overhead.
