Half of firms yet to report gender pay figures with seven days until deadline
Around half of companies required to submit their gender pay gap figures to the Government have yet to do so, with a week until the deadline.
By April 4 an estimated 9,000 companies and public bodies with 250 employees or more have to have submitted their median and mean gender pay gap data to the Government Equalities Office.
As of 2pm on Tuesday, figures show that just 4,428 have done so so far, with 78% of those having a pay gap.
The rest of the employers either have no median gender pay gap (8%) or one in favour of women (14%).
A Home Office spokesman said that the thousands of companies who have yet to provide their figures could face legal action if they miss next week's deadline.
He said: "This Government is clear that tackling injustices like the gender pay gap is part of building a country that works for everyone. Shining a light on where women are being held back means employers can begin to take action.
"Reporting gender pay gap data is not optional; it is the law, and employers that do not comply will risk facing legal action from the Equality and Human Rights Commission.
"This is the first year of reporting and we will use the results to target our efforts effectively as we continue to work with employers towards eliminating the gender pay gap."
Of the 353 councils in England, 128 have yet to report their figures.
They join the 63% of hospital trusts and 47% of universities who are also still to send the Government their data.
The gender pay gap is calculated as the difference between the average salaries of men and women - it is not the same as equal pay, where firms are required to pay people doing the same job the same salary regardless of gender.
The national median gender pay gap is 18.4%.
