Hi jackie and welcome to the forum
If this is your only debt, and you are happy to pay off relatively small amounts just to stop the collections procedure, then you should tell the bank of your new address and re-commence payments to them.
You might also want to consider bankruptcy proceedings of all you can afford is £5 per month, as the debt will just continue to grow as ongoing interest is levied. A shame to have to do this for a relatively small sum, but it would remove the debt for ever and you probably would not pay any contributions by way of an Income Payments Order.
Are you a property owner or do you rent?
