Contracts below the publication thresholds and those of devolved buyers that publish elsewhere are not included.

A positive gap means women's average hourly pay is lower than men's across the whole employer; it is not a comparison of pay for the same work. View on the Gender pay gap service

Figures the company reported itself to the government's Check payment practices service, Gender pay gap service and Modern slavery statement registry (Open Government Licence v3.0). Only large companies and employers with 250 or more staff have to report, so most companies have nothing here.
