In case anybody else is wondering - these details are public. Any time you see a story about a UK company, and this one is no exception, you can get some information about it from the company registry at Companies House: https://beta.companieshouse.gov.uk/

1. type in company name or part thereof

2. select it from the list

3. click the "people" tab and see if you recognise any names from the article or whatever (this can be helpful if there were several likely-looking results)

4. click "filing history" and download the accounts and annual return (with list of shareholders)

Most of the time this isn't actually very interesting, but if you're being nosey, there's no reason not to. (The reduced accounts you have for small companies (turnover < £15m, something like that...) are usually particularly unilluminating, though some of the figures can be suggestive and the shareholders list may be interesting.)
