Cyber Essentials Admin Account Checklist for UK Businesses
17 August 2026
A practical UK guide to meeting Cyber Essentials admin account requirements. How to control, audit and secure admin access in 2026.
Why Admin Accounts Matter in Cyber Essentials
In the UK Cyber Essentials scheme, administrative accounts are a key focus because they hold elevated privileges. If an attacker compromises an admin account, they can bypass security controls, install malicious software, and access sensitive data. The NCSC and IASME require you to demonstrate that you have control over these accounts. This means knowing exactly who has admin rights, why they have them, and ensuring they are not used for everyday browsing or email. A proper admin account checklist helps you pass the assessment and reduces your real-world cyber risk, which is the whole point of the certification.
The Complete Admin Account Checklist
Work through this checklist to align with Cyber Essentials. Inventory every admin account, whether on laptops, servers, or cloud services. Ensure each admin account belongs to a named individual and is never shared. Create separate standard user accounts for daily work. Enforce strong, unique passwords and change them immediately if compromised. Enable multi-factor authentication wherever possible. Disable or delete default local accounts like 'Administrator' on Windows. Apply the principle of least privilege – give users only the rights they need. Finally, track access in an audit log and regularly review active admin accounts.
How to Implement Admin Account Controls on Windows
For most UK small businesses using Windows, start by creating standard user accounts for all staff in 'Settings > Accounts'. Then elevate only essential users to 'Administrator' via Local Users and Groups (lusrmgr.msc) or Active Directory. Rename and disable the built-in Administrator account, and make sure User Account Control (UAC) is set to always prompt. Use a password manager to generate and store complex admin passwords. For cloud services like Microsoft 365, use conditional access policies to require MFA for admins. Regularly export a list of admins from Azure AD or your domain controller and review it. This practical setup meets Cyber Essentials expectations.
Common Admin Account Mistakes That Fail Cyber Essentials
Many UK firms fail technical controls because they use the same account for admin duties and everyday tasks like checking email. Another common issue is setting easy-to-guess passwords such as 'Password1' or leaving the default 'Administrator' account active. Sharing a single admin login works against the audit trail Cyber Essentials wants. Also, forgetting to disable a former employee's admin account is a direct failure. Finally, some businesses overlook user access control on tablets and cloud apps, not just PCs. Avoiding these mistakes will put you well ahead of typical applicants and ensure your assessment goes smoothly.
Maintaining Compliance and Documentation
To stay compliant with Cyber Essentials, create a simple access control policy that documents who administers each system. Review admin accounts at least every 30 days, and always update your records when staff join or leave. Schedule quarterly audits where you check active users, permission levels, and recent password changes. For the IASME assessment, you may need to provide screenshots or logs showing that only authorised users have administrator rights. Keep a spreadsheet or IT tool updated with the date of each review and any changes made. This paperwork is essential and also helps you manage leavers promptly.
FAQ
Cyber Essentials requires that you restrict administrative privileges to only those users whose roles genuinely need them. You must ensure admin accounts are under your control, have strong authentication, and are not used for general activity. During the assessment, you'll need to evidence your account controls, such as user lists and permissions.
