UK Cyber Security & Resilience Bill Compliance Made Simple
The UK Cyber Security and Resilience Bill is progressing through Parliament and is expected to become law in 2026. Prepare your organisation now for upcoming mandatory cybersecurity and resilience requirements.
Once enacted, non-compliance could result in financial penalties up to £17 million OR 4% of global annual turnover (whichever is higher) for serious contraventions, plus daily penalties of up to £100,000 for ongoing non-compliance. For non-compliance with national security directions: up to £17 million OR 10% of global annual turnover (whichever is higher).
Is Your UK Organisation Subject to
Cyber Security and Resilience Bill Requirements?
The UK Cyber Security and Resilience Bill (CSRB, Bill 329) received its first reading in Parliament on 12th November 2025. This landmark proposed legislation would establish mandatory cybersecurity and resilience obligations across critical infrastructure, digital service providers, and their supply chains. Structured in 5 Parts with 61 sections, the CSRB would apply to organisations operating in the UK or providing services to UK essential services, creating proposed requirements that will apply once the Bill becomes law.
Action is required now. The Bill is expected to become law in 2026, with implementation occurring in phases. The government intends to consult on implementation in 2026, with compliance timelines to be confirmed through secondary legislation. Organisations should begin preparation immediately to ensure readiness once the Bill receives Royal Assent.
