Yes, in the right circumstances debt consolidation can be beneficial and help you manage your debt. If you have all your debts in one place, it means that you only have to track one interest rate and one payment to make each month.
However, before applying for a consolidation loan you should review your options to make sure that the loan which you are considering is right for you. For example, compare the rates of interest between your current loan providers and your proposed Post Office Money Loan and consider how long the loans are for.
In some circumstances taking out a consolidation loan could mean you end up paying a higher rate of interest and / or it may take longer for you to pay the money back.
