This is an interesting question that I was asked during the week. And for clarification, I take the question to mean, how much will I be allowed to live on, to cover normal day to day expenses, while I make payments under a Debt Settlement Arrangement.
It all depends on the household formation. Single person or a Couple, with or without dependants, with or without a motor vehicle, with or without other special circumstances. To fully answer this question for your personal situation you need a specialist adviser, either an approved Debt Management Firm or a PIP (Personal Insolvency Practitioner) to guide you through the legislation. It is worth pointing out that many clients will be allowed a greater allowance from their Bank or Creditors, where an informal arrangement is agreed by negotiation. This is where the experience of your insolvency professional really makes the difference.
