Hi. By plc do you mean a business account? If so, yes, but with difficulty. Apperently Barclays and Natwest have helped other IVA'ers in the past, but can only be approached if none of your debt is with them or any members of their groups of companies.
My opinions are merely that .. opinions based on experience. Always seek professional advice.
