How long does Cyber Essentials certification take?
If you run a small or medium-sized business in the UK, you’re probably wondering how long Cyber Essentials will take because procurement deadlines, client requirements and internal calendars don’t pause for IT projects. Short answer: it depends. Longer answer: here’s a practical, no-nonsense breakdown based on working with organisations across the UK.
What Cyber Essentials actually involves (briefly)
Cyber Essentials is a government-backed scheme that proves you’ve got basic defences in place against common cyber attacks. There are two flavours most businesses worry about:
- Cyber Essentials (self-assessment) — you answer a questionnaire about your systems and policies, and an accredited body checks it.
- Cyber Essentials Plus — includes the self-assessment plus technical testing of your devices and infrastructure.
Don’t get hung up on the names. For most businesses the question is how long until you have a certificate you can show prospects, buyers or a tender panel.
Quick timelines you can plan around
These are realistic windows based on typical SMEs (10–200 staff). Your mileage will vary if you have complex hosting or a branch office overseas.
- Ready-to-go small business: 1–5 working days for Cyber Essentials (self-assessment).
- Typical small/medium business needing minor fixes: 1–4 weeks to complete self-assessment and receive certification.
- Cyber Essentials Plus (with testing): 2–8 weeks, depending on scheduling and any remediation required.
Why ranges? Because certification isn’t just a paperwork exercise — you may discover issues that need fixing, and those fixes take calendar time.
Factors that speed things up — or slow them down
Here are the common realities I see in the field that affect the timeline.
1. How prepared you already are
If your systems are patched, accounts are tidy, and you have basic policies documented, the questionnaire is quick. If you’ve got legacy kit, forgotten admin accounts or a policy vacuum, expect extra days or weeks.
2. Who’s doing the work
If the IT lead is internal and available, things move faster. If you rely on an external supplier who needs calendar time, add scheduling delays. I’ve sat in plenty of meetings where the accounts team only responded after three reminders — these human factors matter.
3. Size and complexity
More users, more devices, multiple offices or cloud services equal more questions and possibly more testing. An office in a converted mill in Yorkshire with a mix of desktops and remote laptops is different to a single-site team using fully managed cloud services.
4. Remediation work
Most businesses that fail the first assessment don’t fail catastrophically; common issues are missing patches, weak passwords or unmanaged admin accounts. Fixing these can be quick — or slow if devices are out of warranty, you need to replace kit, or you depend on third parties.
Practical step-by-step timeline
This is how the process often plays out in real life, with approximate times.
- Initial check and planning (half a day–2 days): Someone audits the basics — patching, accounts, firewalls and policies — to estimate work.
- Remediation (same day–4 weeks): Applying patches, tightening accounts, documenting policies. For many firms this is the unpredictable bit.
- Self-assessment submission (1 day): Complete and submit the questionnaire to a certification body.
- Validation and certificate issue (same day–5 working days): If everything’s in order the accredited body issues the certificate quickly.
- For Cyber Essentials Plus — scheduling technical tests (1–3 weeks) plus remediation if tests reveal problems (1–4 weeks).
So, for a business that’s generally well-run but needs a bit of tidying, budget two to four weeks if you want to be conservative. If you’re completely on top of things, you can be certified in a working week.
Tips to get certified faster (and keep costs down)
- Assign a single owner. Having one person chase IT, finance and operations saves days.
- Gather evidence early. Don’t wait for the questionnaire to collect screenshots, policy documents and device lists.
- Patch first. Apply outstanding security updates before you start — it avoids rework.
- Prioritise admin accounts. Remove or secure shared admin credentials early; it’s a common stumbling block.
- Use straightforward hosting and avoid complex outsourced setups during the process, or ensure your suppliers respond promptly.

Costs and scheduling realities
Time and money go together. Faster turnaround often means an external provider prioritises your job or you pay for additional remediation work. If you’re doing the self-assessment internally and patching in quiet hours, you’ll save cash but might take longer. Weigh the urgency of the certificate (tender deadline, client requirement) against internal capacity.
Why this matters beyond the certificate
It isn’t just about a piece of paper. Being ready for Cyber Essentials reduces the day-to-day risk of an incident that could cost more time and money than the certification process. For many UK buyers, having Cyber Essentials is a baseline procurement requirement — so getting certified quickly can prevent lost opportunities and speed up contracts.
Local experience — a practical note
From Ipswich to Glasgow, the same small issues crop up: forgotten USB sticks, default passwords on forgotten printers, and accounts with excessive privileges. These are usually fixable without major investment. In my experience working with teams across the UK, the biggest delays aren’t technical — they’re about people and time. Give someone the mandate to act, and you’ll shave days off the process.
FAQ
How long will Cyber Essentials take for a 50-person office?
Most 50-person offices that are reasonably maintained can complete the self-assessment in 1–4 weeks. If you go for Plus, add a few weeks for testing and any fixes.
Can I get Cyber Essentials done in a week?
Yes — if your systems are up to date, policies are already documented and the right people are available to respond quickly. It’s not the norm, but it’s possible.
What causes certification delays?
The usual culprits are delayed responses from internal teams, unresolved patching or account issues, and scheduling tests for Cyber Essentials Plus. Fix those and you’ll move faster.
Do I need to be offline for testing?
No. Testing is designed to be non-disruptive. Any tests that could affect operations are usually scheduled at a quiet time you agree in advance.
How often do I need to renew?
Certificates last a year and you’ll need to repeat the process annually to keep the badge valid.
Final thought and soft CTA
In short: if you’re organised and honest about what needs fixing, Cyber Essentials doesn’t have to be a long distraction. Allow a couple of weeks as a sensible buffer, or longer if your infrastructure needs work. The upside is tangible — faster tenders, better credibility and a bit more calm when you think about security. If you want to shorten the timeline and focus on business outcomes rather than paperwork, consider getting practical help to smooth the process — you’ll save time, reduce costs and gain credibility faster.
