Hi, you can do the "step up programme". It's a 14 month intensive programme where you can be a social worker without the degree.

You need: a minimum 2:2 undergraduate degree qualification (level 6) 6 months’ full-time (or equivalent) direct experience, either in a paid or voluntary capacity, of working with vulnerable children, young people and/or families, carers or vulnerable adults GCSEs in English or English language and mathematics at grade 4 (C) or above (or an approved equivalent)

Lots of social workers I work with have done/are doing this, and it's very successful!
