The tragedy prompted a change in culture at Transport for London, with both new-build and existing infrastructure subject to rigorous – and rigorously enforced – inspection. As one supplier puts it: “They have very professional people who are going around after the job’s finished. They stick to the specification religiously and anybody found substituting anything gets a damn good kicking.”

Fast-forward three decades and the question is: will the tragedy at Grenfell Tower last summer have a similarly revolutionary impact on the management of residential and commercial property?
