Explained
How this chart is built
Every UK company files a confirmation statement with Companies House at least once a year, and private companies list their shareholders in it. The chart takes each company's latest statement with a shareholder list and follows every shareholder that is itself a UK company to that company's own statement, layer by layer. Holdings work the other way: every company whose latest statement lists the company as a shareholder, then the companies those hold.
A stake is the share of the company's issued shares, weighted by nominal value where the statement gives it. Each statement shows the position on its own date. Shareholders are matched to UK companies by their registered names, so a holder can occasionally be matched to the wrong company or not matched at all.
