This is 2017. I run a number of pub history sites around the UK. They are all lacking in modern detail.
From the 2016 Annual report for Mitchells & Butlers, there are :
43 Alex sites (Germany),and in the UK are 51 All Bar One, 148 Ember Inns, 229 Harvester, 128 Premium Country, 36 Stonehouse, 25 Browns, 114 Castle, 76 Crown Carveries, 127 O'Neills, 52
Miller & Carter, 80 Nicholsons, 291 Suburban, 173 Toby Carvery and 195 Vintage Inns. A total of 1645 in the UK, by my reckoning.
