Cyber Essentials is getting a major update in April 2026.

These changes will affect every UK business that wants to achieve or renew its Cyber Essentials Certification.

While the five core controls will remain the same, the National Cyber Security Centre (NCSC) and IASME will be introducing new rules in an attempt to strengthen security and remove any confusion.

As a top leading IT provider, we’re here to explain these updates in plain English, no technical jargon that might feel overwhelming.

We aim to help and prepare you ahead of your certification to ensure your business can achieve cyber essentials in 2026 with ease.

These changes apply to all assessment accounts created after 26 April 2026.

If your assessment starts before April, you’ll have six months to complete it under the old rules.

6 Changes To Cyber Essentials You Need To Know!

1. Mandatory Multi Factor Authentication

Multi‑Factor Authentication (MFA) is no longer optional for all cloud services.

It will now be a mandatory requirement for all cloud services, and failing to enable it will result in an automatic fail. The NCSC has introduced this because MFA is one of the most effective ways to stop cyber‑attacks.

“Multi‑factor authentication (MFA) will now be a mandatory requirement for all cloud services where it is available.”

If your business hasn’t rolled out MFA yet, now is the time.

We can help you implement it across your organisation with minimal disruption.

2. Mandatory Updates Will Be Required

Two new “auto‑fail” questions have been added around security updates.

If your business doesn’t install high‑risk or critical updates within 14 days, you will automatically fail the assessment.

Updates Apply To:

Operating Systems
Router and Firewall Firmware
Applications and Associated Files

“Are all high‑risk or critical security updates… installed within 14 days of release?” (A6.4 & A6.5)

Unsure Whether Your Systems Meet This Requirement?

At Syn-Star we can run a compliance check during your online cyber security review and help you put the right processes in place to ensure your set-up is in-line ahead of your upcoming cyber essentials certification.

Upcoming Webinar: Cyber Essentials Made Simple

Monday 23rd of March at 14:00 pm 

In this webinar Giles Cleverley will cover:

  • Overview of the upcoming updates
  • What the new rules mean for your business
  • The risks of not preparing in advance
  • The actions you can be taking right now

What’s in Scope Has Expanded

The rules around what must be included in your assessment have been tightened.

Key Changes Include:

More detailed scope descriptions on your certificate.
You must list any areas you are excluding (these won’t be public).
You will need to justify any exclusions added
You must explain how excluded networks are separated from in‑scope systems.
Cloud services cannot be excluded from scope.

“Cloud services cannot be excluded from scope.”

If your business has multiple sites, departments, or cloud tools, we can help you define your scope correctly.

‘Point in Time’ Is More Strict

Cyber Essentials has always been a “point in time” assessment, but the definition is now clearer:

“The ‘point in time’ is the date the certificate is issued.”

This means your systems must be compliant on the day your certificate is issued, not just when you start the assessment.

We can help you stay compliant throughout the process so there are no last‑minute surprises.

There Are New Certificate Types

If your business includes multiple legal entities, you can now request individual certificates for each one while still being part of a wider assessment.

“You will be able to request an individual Cyber Essentials certificate for every legal entity certified as part of a larger scope.”

This is useful for groups, franchises, or organisations with multiple trading names.

New Legal Entity Identification Needed

You must now clearly list all legal entities included in your assessment.

New Legal Entities Include:

Company Name
Registered Address
Company Number

“Organisations will need to specify all legal entities included within the scope of the assessment.”

This improves transparency and ensures certificates accurately reflect who is covered.

If you’re unsure how to structure your assessment across multiple entities, we can guide you.

Changes to Cyber Essentials Plus (CE+)

If you go for Cyber Essentials Plus, there are two important updates:

1. Update Management Will Be Checked More Thoroughly

If you fail the first device sample test, you must fix the issues and undergo a retest.

The retest will include a new random sample to ensure updates were applied across your whole environment not just the tested devices.

This prevents businesses from “selectively updating only the tested devices.”

2. You Can’t Edit Your Self Assessment After the Cyber Essentials Testing Starts

Once your Cyber Essentials begins, your Verified Self‑Assessment answers are locked in and can’t be adjusted.
