Just to remind people what the MTST policy is
The Source of Wealth is mostly asked for UK players, in order to make sure there are players who're not playing if they're loaning funds, in debt, unemployed with no income, low salary, or on welfare.
This is something the UKGC has ruled which we need to follow in order to be able to operate in the United Kingdom.
and
The reason for closing accounts or limiting them due to, debt, loans, salary or similar is case by case based and SOW is something we use to find out if a person is in a financial position that has room for gambling or not.
So I wouldn't be sending bank statements, mortgage statements, credit card statements, payslips showing minimum wage or part time work, or anything showing you get working tax credit, child benefit etc to any of the companies if you want to keep your account.
