I'm not from the UK, but from a distance (the other side of Europe) it looks like UK's ongoing economic implosion seems to also have been caused by the people over there going all in on "the service industry!" sometime in the late '80s - the '90s, and leaving aside almost anything that involved making physical things, from roads to steel to stuff like that.

Imo that might work for a very small country or for a city-state (like Hong Kong or Singapore, even though these also used to make actual stuff), but I don't think you can base the economy of a country as big and developed as the UK is entirely on services. At most you get a pseudo-city-state, which is what London looks like, surrounded by economic "blob". It's not London that built modern UK, but the likes of Manchester, Birmingham, Glasgow and, yes, Newcastle and the North-East of England. All those cities might as well not exist now, from an economic pov.

Of course, I might be totally wrong on this as I don't live in the UK, but I've got most of that by reading David Edgerton's The Rise and Fall of the British Nation: A Twentieth-Century History [1] recently. (a Economist editorial from a couple of weeks ago was also quoting David Edgerton, if it matters)
