The League Tables figures used for John Nicholls in the print version of BMJ’s January issue were for John Nicholls (Trading) rather than John Nicholls (Holdings) and, therefore, do not take into account the figures of J & Bs, the Dorset-based plumbing and heating merchant that John Nicholls owns.

Apologies for the error. The correct figures are: Turnover 2017: £47,020,041, Turnover 2016: £40,707,358, employees: 199, branches 13.

The correct fgures appear both in BMJ’s digital version (here) and on the downloadable PDF (here)
