Planning and Infrastructure Bill

Debate between Lord Teverson and Lord Jamieson

Committee stage
Thursday 4th September 2025 Lords Chamber

[Lord Teverson (LD)]

My Lords, from these Benches I support this amendment and thank other Lords for their support. One thing the noble Viscount, Lord Hanworth, said is that if we had had a digital twin model earlier, the bat tunnel we talked about would probably never have been necessary in HS2.

Clearly, there are issues around this on data privacy, keeping information up to date, legacy systems and so forth. But one of the positives is that once you have a model, you do not just discard it once the project has finished; you continue using it into the future and update it. It allows you all the benefits into the future.

We on these Benches are very interested to hear where the Government are in the development of this area, which I certainly hope is an area where the UK, with its IT prowess, will move ahead of our competitors and use it for the kinds of not very successful infrastructure projects that we have had in recent years.

[Lord Jamieson (Con)]

My Lords, in speaking to the amendments of the noble Baroness, Lady Miller of Chilthorne Domer, I am also greatly pleased to say that we seem to have broken out into a spirit of co-operation. As noble Lords will know, modelling and simulation are used to drive efficiency in infrastructure and planning projects. I recall, as a project engineer more than 30 years ago, using simulations and realising just how valuable they are in avoiding mistakes and bringing people on board with exactly what you are proposing.

Therefore, they have the potential to reduce costly mistakes in the planning process, deliver infrastructure that is better, more adaptive and more resilient and, as Members have commented, bring residents and others on board because they can see what is there. They would also, I hope, allow developers to modify their plans to reflect what the public want because it can be done so much more easily through a model.

This technology is moving at pace, as are other technologies such as AI, and it is therefore likely that legislation will be required in future to keep pace with changes. Ensuring that the law remains sufficiently flexible and future-proof and does not inhibit development is going to be important, as is how this is integrated into the planning system as opposed to being a stand-alone, nice little model that you look at. If we are going to look at amendments and how changes can be made, we have to think about whether that means we need to produce a volume of paper documents or whether there is some output that we can integrate. It is a complex issue that we need more thought on, but it is a great opportunity. How do the Government intend to ensure that this planning law evolves, and how can it be integrated so that planners are able to realise the full potential of technology? I look forward to hearing the Minister’s reply.
