In this second of a two-part interview with Peter Rickaby, we discuss the challenges of how we upgrade the UK’s historic housing stock and the difficulties we face with our hard-to-treat properties. We talk about heat pumps and the additional energy we’ll need to electrify heating as well as low carbon heat networks and where it could and should be used in conjunction with reducing the energy demand for our homes. And procurement – are the contracts here that we need to deliver retrofit at scale and what do we need from our procurement managers to do so.
