Cyber Essentials Plus Certification in London
Achieving the audited tier of the UK baseline for London organisations, where an assessor tests the estate rather than reading your answers. The same five controls apply as at the basic level; the difference is that somebody samples real devices and attempts to demonstrate that what you declared is true.
Why this comes up
The problem
The self-assessment passed last year and the audited assessment has failed on machines nobody had checked.
What you get
What we deliver
- The device estate reconciled first, since the sample is drawn from what exists
- Unsupported operating systems and software found and dealt with before assessment
- Patch levels verified across the sample rather than assumed from a console
- Multi-factor authentication confirmed on cloud services, including the forgotten ones
- Browser and application configuration checked, as these are common failure points
- A pre-assessment run internally, because a failed audit costs a full re-test

Cyber Essentials Plus Certification in London — common questions
- What actually changes at the audited level?
- Verification. The basic level is a self-assessment answered by you; here an assessor selects a sample of devices and users, tests them directly, and confirms the controls are in place — so anything that was answered optimistically surfaces.
- What causes most failures?
- Unsupported software and missed devices. A machine running an operating system past end of support, an old browser, or a laptop that never appears in the management console will fail the assessment, and each is discovered during the audit rather than before it.
- Why reconcile the estate first?
- Because the sample is drawn from reality rather than from your list. Devices absent from your inventory but present in the business — a director's personal laptop, a machine in a workshop — are exactly the ones that will fail, so finding them is the first task.
- Is a pre-assessment worth it?
- Almost always, because failure is expensive in time as well as fees. Running the same checks internally a few weeks ahead identifies the handful of devices and settings that need attention while there is still time to fix them quietly.
- Do you work with businesses across Greater London?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout London, including London and the surrounding Greater London area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of London businesses do you usually work with?
- Clients here are usually replacing an agency, and want senior people on the work at rates that are not Central London rates. Beyond that we work across Financial Services, Professional Services, Technology, Media, Hospitality and Retail.
- Do you cover the areas around London?
- Yes — we work throughout London, including Reading, Milton Keynes, Cambridge, Brighton. London is an urban area of roughly 9,000,000+, and we take on work across the wider Greater London region rather than the city boundary alone.
