What is ISO 27001 certification?
ISO 27001 is the international standard for information security management systems. It provides a framework for protecting sensitive business and client data, and is required by many UK financial services firms, NHS suppliers, and government contractors.
How long does ISO 27001 take in the UK?
ISO 27001 typically takes 6 to 12 months for a UK business to achieve, making it one of the more complex ISO standards. Organisations with existing security controls and documented policies can move faster, often achieving certification in 4 to 6 months.
How much does ISO 27001 cost UK businesses?
ISO 27001 certification in the UK costs between £8,000 and £40,000 depending on organisational size, the complexity of your information assets, and whether significant technical controls need to be implemented.
What is the difference between ISO 27001 and Cyber Essentials?
Cyber Essentials is a UK government-backed baseline scheme covering five technical controls, achievable in weeks. ISO 27001 is a comprehensive international standard covering the full information security management system, requiring 6 to 12 months and third-party audit. Many UK businesses achieve Cyber Essentials first, then progress to ISO 27001.
Is ISO 27001 required for UK government contracts?
ISO 27001 is not universally mandated but is listed as a requirement or strong preference in many central government and Ministry of Defence supply chain frameworks. NCSC guidance increasingly references ISO 27001 as the standard for organisations handling sensitive government data.
