Cyber Essentials certification costs £300 to £500 for the self-assessment route in 2026, plus a separate technical audit fee for Cyber Essentials Plus that certification bodies price individually based on your device count and scope.
Why this matters
Most founders ask "what does Cyber Essentials cost" expecting a single number. There isn't one.
The certificate fee is published and fixed by employee band. The real cost variable is everything around it: scoping, remediation, evidence gathering, and whether you need Cyber Essentials Plus for a specific contract or insurer requirement.
Get the scope wrong in 2026 and you'll pay for a reassessment. Get it right and Cyber Essentials certification cost stays predictable year after year.
What you'll need
- A confirmed employee headcount for your certifying organisation (this sets your fee band)
- A scope decision — whole organisation or a defined sub-set of systems
- An asset list: laptops, servers, mobile devices, cloud services, and firewalls in scope
- A nominated internal contact who can answer the technical questionnaire
- Time budgeted for evidence gathering, not just the certificate fee itself
- A decision on Cyber Essentials vs Cyber Essentials Plus before you request quotes
The steps
1. Confirm your organisation size band
IASME-licensed certification bodies price Cyber Essentials by employee count, not revenue or industry. The published bands are: micro (0-9 employees) at £300, small (10-49 employees) at £400, medium (50-249 employees) at £450, and large (250+ employees) at £500, all plus VAT.
Check your headcount against payroll, not a rough guess — certification bodies verify this during application, and getting it wrong means a corrected invoice partway through.
Common mistake: counting contractors or part-time staff inconsistently and landing in the wrong band.
2. Decide between Cyber Essentials and Cyber Essentials Plus
Cyber Essentials is a self-assessment questionnaire, reviewed and verified by an assessor. Cyber Essentials Plus adds an independent technical audit — vulnerability scans and, often, on-site or remote device checks.
Plus certification cost isn't on a fixed national table like the base fee. Certification bodies price it per engagement based on how many devices, servers, and locations sit in scope, so two businesses of the same size can get different quotes.
If a client contract, insurer, or OneClickComply client onboarding process requires Plus specifically, confirm that before you request quotes — asking for the wrong certification wastes a scoping call.
3. Get quotes from more than one certification body
Base Cyber Essentials pricing is standardised, but Plus audit quotes are not. Request quotes from at least two IASME-licensed certification bodies and compare scope assumptions line by line, not just the headline figure.
If your Plus quote looks high, the guide on reducing the cost of Cyber Essentials Plus certification walks through the scope reductions that move the number without cutting corners on security.
Expected outcome: a written quote breaking out audit fee, device sampling method, and any retest allowance.
4. Budget for remediation before the assessment date
Remediation is the cost most businesses forget. If your firewall rules, patch cadence, or access controls fail a technical control during assessment, you pay to fix the gap and often pay a resubmission fee too.
Run an internal check against the five Cyber Essentials control areas — firewalls, secure configuration, access control, malware protection, patch management — before your assessment date, not after a failed one.
Common mistake: treating the assessment as a checkbox exercise instead of budgeting a few days to close obvious gaps first.
5. Factor in the annual renewal cost
Cyber Essentials certification lasts 12 months. Renewal isn't discounted — it's essentially the same self-assessment fee and, for Plus, another technical audit.
Treat certification as a recurring 2026 line item, not a one-time spend. The guide to renewing Cyber Essentials certification each year covers the timeline for starting renewal before your current certificate lapses.
6. Add insurance and procurement costs where they apply
Some cyber insurers price premiums against Cyber Essentials status, and some UK government and enterprise contracts require it as a supplier condition. If either applies to you, the certification cost isn't just the fee — it's a gate to revenue or lower premiums, which changes how you justify the spend internally.
7. Automate evidence collection to cut the hidden labour cost
The certificate fee is fixed. The hours your team spends screenshotting firewall configs, patch logs, and access lists is not — and that's where most of the real Cyber Essentials certification cost hides in 2026.
OneClickComply automates evidence collection for Cyber Essentials so your team answers questions once instead of chasing screenshots every renewal cycle. Seriously simple cyber compliance means the certificate fee stays the same and the labour around it shrinks.

Troubleshooting
- Quote is higher than the published band. Check whether your certification body is quoting Plus audit fees alongside the base fee, or whether your device count has grown since your last scoping conversation.
- Assessment failed on a technical control. Fix the specific control gap and resubmit — most certification bodies allow a retest, sometimes at an added cost, so ask about retest fees upfront.
- Scope keeps expanding mid-assessment. Lock your scope document before quoting. Adding cloud services or remote devices after the quote is issued is the most common reason costs climb.
- Renewal lapsed before you restarted the process. Start renewal 60-90 days ahead of expiry so a delayed assessor slot doesn't leave you uncertified.
- Plus audit flags legacy devices you forgot were in scope. Run an asset inventory refresh before every audit cycle, not just the first one.

What to do next
Once you know your fee band and have quotes in hand, decide whether Plus is contractually required or optional this cycle — that single decision moves your Cyber Essentials certification cost more than any other factor. If a client or insurer is pushing you toward Plus, read the guide on aligning Cyber Essentials with cyber insurance requirements before you commit to a scope.
Frequently asked questions
One last thing
The published fee band rarely surprises anyone — £300 to £500 is £300 to £500. What surprises businesses in 2026 is the resubmission fee after a failed control check, which is entirely avoidable with a pre-assessment review of firewall rules and patch status.
