Historical version 8 of Category Capital Pub Company (view current version)
Starting as a small pub company with a couple of dozen pubs throughout London, the Capital Pub Company was bought by Greene King in 2011.
They had an off-shoot rather imaginatively called Capital Pub Company 2, but this now seems to be a separate entity called Convivial London Pubs.
