Investigating UK Companies: What can we learn from the ONS and Companies House?

Last week I found a page by the Office for National Statistics (ONS) breaking down UK companies by Standard Industrial Classification and turnover. I noted it in my weekly Consumption post, and I’ve decided to dig into it further to find out what other interesting information the ONS and Companies House may provide. The data I found last week was from 2018 - a bit old. It was filed under Activity, size and location, and looking there, I found a wealth of more up-to-date publications and data. Two in particular stood out.
