UK games companies with more than 250 staff are having to reveal the pay gap between male and female employees - and the results show a startling disparity.

Companies across the country have until midnight on April 4th to submit the gender pay figures.

According to the BBC, of those that have published data so far, 78 per cent of companies pay men more than women, 13 per cent pay women more, while eight per cent reported no gender pay gap.

We’ve broken down the gender pay gap of each games company reporting in below.

So far in none of these instances are women paid more than men based on the figures as presented.

Data is currently unavailable on companies such as Ubisoft and Activision. Companies that don't submit their figures could face fines.

We'll update this article as more games companies reveal their figures.

Jagex

The mean hourly rate for women at RuneScape developer Jagex is 21.7 per cent lower than men’s - meaning women earn 78p for every £1 that men earn. Women’s median hourly rate is 18.4 per cent.

Of the top earning quartile - the highest paid - 9.2 per cent are women. The upper middle quartile has 14.3 per cent women, the lower middle quartile 18.2 per cent, lower quartile - the lowest paid - 29.9 per cent.

It claimed it would be implementing a number of initiatives aimed at reducing the gender gap at the company, including improving parental benefits, providing flexible working conditions, and ensuring it continues to adopt a process of equality in shortlisting applicants.

"Because EA also currently employs more men than women, particularly at senior and higher paid roles, the calculations that EA is required to report under this regulation show a wage difference based on gender."
