What is the Cyber Security and Resilience Bill (2025)?

18th July 2025

With cyber threats constantly evolving, the UK government are set to make improvements to cyber security legislation, for greater resilience and regulation.

In 2024, it was announced as part of the King’s Speech that the Cyber Security and Resilience (CS&R) Bill would be introduced over the next two years. The purpose of the bill is to modernise and improve the UK’s cyber security framework. So, what is the bill rumoured to contain?

Organisations such as Managed Service Providers (MSPs – like us!), data centres and critical suppliers will be brought under regulation and held to higher security standards. Often, breaches occur when one link in the chain has poor defences – this will improve resilience not just for these organisations, but those connected to them.

Additionally, the regulators in question will be given better enforcement tools, allowing them to mandate measures and penalise non-compliance with fines and audits. These regulators include National Cyber Security Centre, Department for Science, Innovation and Technology, Ofcom, Ofgem, Ofwat, Civil Aviation Authority and Information Commissioner’s Office.

Furthermore, these organisations will be able to use tools like the Cyber Assessment Framework (CAF) and Cyber Essentials to keep businesses up to a high standard of cyber security. A broader range of incidents will need to be reported, to give the government a better picture of national cyber threats.

The bill will reflect lessons from recent attacks, modernising legislation to keep up with emerging technology. Attacks such as the 2024 Synnovis NHS breach, that caused widespread delays and difficulties, helped the UK government to realise where improvements should be made.

What impact will the bill have? Businesses will have to update their cyber security measures to meet these higher standards. For some industries, few changes will be needed, but for critical services it may be a significant step forward.

Also, incident response plans and supply chain risk assessments will likely become more essential than ever. If you’d like any more information about the CS&R bill, please contact Interfuture Security, we’d be happy to discuss it.
