UK NIS Regulations Compliance — and the Cyber Security and Resilience Bill
The NIS Regulations 2018 require UK operators of essential services — energy, transport, health, drinking water, digital infrastructure — and relevant digital service providers to manage cyber risk and report significant incidents. Regulators commonly use the NCSC CAF to assess them.
The Cyber Security and Resilience Bill is set to widen the regime to managed service providers, data centres and critical suppliers, with faster incident reporting. Mutex Systems helps current operators stay compliant and helps MSPs and suppliers prepare.

What are the UK NIS Regulations?
The Network and Information Systems Regulations 2018 require operators of essential services and relevant digital service providers in the UK to take appropriate security measures and report significant incidents to their competent authority.
What is the Cyber Security and Resilience Bill?
UK legislation that updates and expands the NIS Regulations — bringing managed service providers, data centres and critical suppliers into scope and strengthening incident reporting and regulator powers.
Is UK NIS the same as EU NIS2?
No. The UK kept the original NIS framework after Brexit and is updating it separately. Groups operating in both the UK and EU may need to meet both.
