It may not be too difficult to open an account in France, as they are unlikely to do much credit checking back to the UK. You will of course need to maintain your IVA contributions, and this is easy to do on-line.
Why not keep your UK bank account which will allow you to make cash withdrawals in Europe, surely? How are you currently paying your IVA? If by standing order then this arrangement can continue.
It might be sensible to keep both bank accounts running - use your French one for everyday expenses, and your English one for commitments back in the UK including the IVA payments.
