Shell have revealed that male staff working for the company on average earn 22 per cent more than women in the UK.
The oil company have promised that despite the gap, it is confident it pays equally for equal work.
They explained that the gap in pay is due to a skills gap, as opposed to gender discrimination.
New government legislation requires companies with over 250 employees to publish gender pay gap figures year on year.
Each of the data will be added to a government database that attempts to tackle workplace inequality.
According to the Office for National Statistics, the median UK gender pay gap was 9.1 per cent for the year to April for full-time workers.
Since the ONS began collecting data on the pay gap in 1999, the figure has almost halved.
Shell UK promised it was making steps to address the representation gap.
According to the company, women in senior management roles had risen from 12 per cent to 27 per cent between 2005 and 2017.
Sinead Lynch, chair of Shell UK, said: “Equal Pay ensures men and women are paid equally for work of equal value.
“We know it will take time and we will continue to tackle the root causes of imbalance.
This includes sponsoring and engaging in STEM programmes for girls, working to eliminate any unconscious bias in our systems, processes and policies and continuing to foster a culture of inclusion at every level.”
Ronan Cassidy, chief human resources and corporate officer at Shell, commented: “Are we where we aspire to be? No.
But we should recognise the significant progress we have made, especially the marked change in gender balance at recruitment and the increase in senior leadership representation, and draw confidence from that for the future.”
Shell said action would include tackling the ‘root causes of imbalance’ and wider societal issues, with women representing around one-fifth of all employees in the oil and gas sector.
They added that only 25 per cent of UK graduates in science, technology, engineering and mathematics (STEM) are women, and so plans are in place, including ‘sponsoring and engaging in STEM programmes for girls, working to eliminate any unconscious bias in our systems, processes and policies and continuing to foster a culture of inclusion at every level’.
