WSP’s Positive Impact Podcast

Much of the UK’s infrastructure is ageing and yet it remains fundamental to how society functions. From the moment we turn on the lights or run a tap, to travelling by road or rail, we rely on assets that were often built decades, even centuries, ago. At the same time, budgets are constrained, climate pressures are intensifying and public expectations continue to rise.

So how do we make sure the infrastructure we already have continues to perform safely, reliably and sustainably, long into the future?
In this episode of WSP’s Positive Impact Podcast, host Lucy Siegle explores what it really takes to manage ageing infrastructure in a changing world. She is joined by Steve Denton, Managing Director of WSP’s Civil Engineering Unit and Vice President of the Royal Academy of Engineering, and Professor Andrew McNaughton, Chair of Network Rail High Speed Limited, for a wide‑ranging and thoughtful conversation.

Together, they unpack why ageing infrastructure has become such a pressing issue, why asset management is ultimately about decision‑making rather than just maintenance, and how uncertainty plays a central role when dealing with long‑life assets. They reflect on the reality that almost everything we depend on today will still need to be working decades from now — and that rebuilding everything simply isn’t an option.

With practical insights, real‑world examples and honest reflections from decades of experience, this episode is a must‑listen for anyone interested in the future of infrastructure, decarbonisation, resilience and how we make the most of what we already have.
