You could take out a consolidation loan, or re-mortgage to reduce interest charges on their debts and combine payments for ease of use. But it is important to realise that you may loose your home if you are unable to make payments. Debt Management offers similar benefits, but without any risks.
Consolidation loans and mortgages are usually paid off over a longer period of time. Even with lower interest rates, you will pay more in the end. It may cost money to settle an existing loan, such as paying any redemption penalties.
Some advantages they offer are, lower interest rates, a lower monthly payment and dealing with a single creditor. Debt Management offers nearly all of the advantages, without the risks.
