The Equality Act 2010 (Gender Pay Gap Information) Regulations 2017UK Government requires companies employing more than 250 people to regularly publish their gender pay gap information.

The government-defined gender pay gap metric measures the difference between the average earnings of all females in the organisation and the average earnings of all males, irrespective of their seniority or role. This is not the same as equal pay, which compares what men and women are being paid for the same or similar work.
