Gender Pay Gap The trust has a mandatory requirement to publish gender pay gap information on an annual basis. The first set of reporting was required by 31 March 2018, with a snapshot date for the data set as 31 March 2017. The second reporting was required by 31 March 2019 with data from 31 March 2018. To date, NWAS has therefore published two reports of gender pay gap data – for March 2017 and March 2018 snapshot dates.
