PRS for Music has narrowed its gender pay gap but white employees earn up to 26% more than those of colour.
The collecting society has published reports on its gender and ethnicity pay gaps as it announces two new full-time posts to "provide further expertise in equality and diversity".
Its average gender pay gap has decreased from 13.5% last year to 10.6% this year.
However, there is an average wage gap of 20% and a median gap of 26% in favour of white employees over their colleagues of colour.
This is "predominantly driven by the proportion of Black, Asian or ethnic minority background employees in lower banded roles," PRS reports
It says it has trained all hiring managers on inclusive recruiting and increase its use of recuritment agencies that specialise in diverse candidates.
"Internally, the organisation is increasing its focus on nurturing diverse talent using talent reviews and career development plans, including coaching and management development."
