Hello. If you want to actually get such a insurance very quickly then here is the link for you https://www.globelink.co.uk/. I bought a insurance from them and am very happy with it.

I believe that such a building should be protected one hundred percent regardless of whether people live there or it is an office building.

Yes, I completely agree with you, and I myself recently bought an apartment in a similar apartment building and as it turned out, it really costs a lot and repairs were expensive, but the most important thing is that you need to immediately put an alarm system and then there will be no problems. Before buying an apartment, I searched and read reviews about alarms and as it turned out Ajax was the most reliable thing that could only be. I think that you should definitely look at the website and also get acquainted with the entire assortment that they provide. I wish you good luck!
