Question to the Department for Science, Innovation & Technology:

To ask the Secretary of State for Science, Innovation and Technology, what assessment she has made of the cost of technical debt to UK productivity; and what steps her Department is taking to address skills shortages linked to the retirement of personnel maintaining legacy IT systems critical to national infrastructure.

At least 28% of central government systems are classified as legacy. These outdated systems cost around 40% more to maintain than modern alternatives, slow down public services, are harder to join up and increase the risk of disruption, reducing efficiency across government and contributing to wider productivity challenges.

DSIT is committed to addressing this technical debt. We are undertaking work to identify the most cost-effective methods for modernising outdated systems, which will inform the Technology Modernisation Action Plan later this year.

By moving departments off legacy systems, we reduce reliance on retiring specialist expertise. Alongside this, through Get Tech Certified, over 9,000 public servants have accessed free certification pathways in cloud, AI and modern engineering; equipping the workforce with the skills these modern platforms require.
