Dear Colin
I have just read your post. Before taking out any more credit in order to finance your debts, may I suggest that you contact your local CAB for debt advice first? Yes, you do have other options.
The CAB would never recommend that any debt client takes out more loans in order to finance and pay off their debts. The CAB would produce a financial statement and give you debt advice free of charge too. Most CABX can take you on as a debt client because you live in rented accommodation. They may be able to suggest ways of cutting your monthly expenditure, although somewhat difficult when the CSA want money too!
There are companies that advertise on the radio and TV but BEWARE. They charge for their services. The CAB's debt service is confidential, impartial and free to debt clients. Sometimes the CAB can liaise with financial organisations on your behalf and sometimes they agree to withhold interest payments but not always.
If you have any problems with the CSA, you can either get assistance from the CAB or register on I think it is NCSA's website. if you do a search on CSA, this website will come up. They are experts in dealing with the CSA and any problems. You can type in your financial info and they can assist you with your CSA payments. There is a small annual registration fee to pay.
CABX have an advice system for clients called 'Adviceguide'. You can ask for a factsheet on preparing a financial statement and any other related information.
Good luck with your endeavours.
