Civil Service: Artificial Intelligence Productivity Gains

Viscount Camrose Excerpts

Monday 1st September 2025 Lords Chamber

Asked by

[Viscount Camrose]

To ask His Majesty’s Government what assessment they have made of productivity gains across the Civil Service resulting from the deployment of artificial intelligence; and how they are measuring and evaluating these gains.

[Viscount Camrose (Con)]

I beg leave to ask the Question standing in my name on the Order Paper and, in so doing, draw noble Lords’ attention to my technology interests as set out in the register.

[The Minister of State, Department for Science, Innovation and Technology (Lord Vallance of Balham) (Lab)]

The Government have assessed the potential productivity gains from AI across the Civil Service, identifying which solutions are most effective and that will scale. We conducted the world’s largest trial of general-purpose AI tools, such as Copilot, to measure their impact and benefit. These evaluations inform which technologies deliver which outcomes and will enable us to prioritise adoption. Our assessment indicates significant economic benefits from widespread, well-targeted AI deployment across His Majesty’s Government.

[Viscount Camrose (Con)]

My Lords, in May, the Government announced a rightly ambitious plan to drive tens of billions of pounds per year in Civil Service productivity savings through AI. In June, they estimated that use of AI tools was saving civil servants 26 minutes a day. Even if that is true, the Minister will agree that time savings, however welcome, do not equate to productivity. Now that the Government have spent £573 million on AI tools and consulting for the Civil Service, how will they measure productivity gains to rapidly build on successes and shut down failures?

[Lord Vallance of Balham (Lab)]

The figure of £573 million is, of course, forward spend, so that is not what has been spent; it is a commitment over the next few years. It is important that we measure this. Guidance on how to measure the impact of AI tools was issued last year; there is a rigorous process for doing that. On the 26 minutes that has been picked up by the Copilot study, it is of course a general AI tool. Much greater savings come with specific uses in specific areas, which will not be general across the Civil Service.

The noble Lord is quite right to point out that time saving is not productivity, but what we do know from studies elsewhere and across business is that, when you get those time savings, about half of it goes on core tasks, about a quarter is on other strategic and creative work and about 25% goes on enhanced well-being. That is what we might expect as a result. There is a lot to do to make sure that we implement this properly across the Civil Service.
