Yorkshire Water has revealed it has a 4.8 per cent mean gender pay gap compared to the national average of 17.4 per cent.

The company also has a 4.7 per cent median gap and said on average female employees receive a higher bonus than their male colleagues. The overall percentage of females who receive a bonus is “marginally higher” than that for males, the company said.

Yorkshire Water and its sister company Loop Customer Management released their gender pay gap figures yesterday (3 April) for 3,500 employees.

Companies with 250 employees or more must submit their median and mean pay gap data to the Government Equalities Office by midnight on 4 April.

Richard Flint, Yorkshire Water’s chief executive, said: “Although our gender pay gap figures are significantly below the national average, we are in no way complacent with our current levels of gender diversity. We want to properly reflect the communities we serve.

“This reporting is just the first step in a series of measures that will help us to improve not just our gender balance, but the overall diversity of our whole workforce.”

The company said it will publish a full report, which will detail its current levels of diversity along with how it plans to improve over the next few years.

Loop Customer Management has a mean pay gap of 5.5 per cent and a median of minus 2 per cent due to its high levels of female employees, the company said.

It has a larger bonus gap than Yorkshire Water, due to the rules around reporting bonuses of part-time staff.

The company said: “there is a considerable number of part-time workers at Yorkshire Water’s contact centre, which impacts the figures.”

In 2016, Yorkshire Water received the National Equality Standard accreditation, which recognises good practice in all areas of diversity, equality and inclusion.

The company runs female talent development programmes, diversity and inclusion training for all managers, mentoring and a Diversity and Inclusion Group that looks at ways to improve diversity among staff.

Yorkshire Water also sponsors Forward Ladies in its research into bridging the gender pay gap in science, technology, engineering and mathematics (STEM) careers.
