It may be possible to apply directly to employers if you have some of the relevant skills and knowledge required for this role. It will be useful to have experience in other areas like:
- consumer advice
- welfare rights work
- debt recovery for a bank, council, utility company or similar organisation
Most employers will not ask for qualifications as your experience would be the most important thing. But you should have a reasonable standard of English and feel comfortable with maths.
Your employer may ask you to do additional specialist training.
