DON'T PUT OFF PAYING WHAT YOU OWE
Currently all household bills are expected to be paid as normal - council tax, utilities, water etc.
With usual routines out of the window, it's easy to let things slip. However, if you have an outstanding bill then pay them before any additional interest rates or late payment fees are generated.
If you are worried about your ability to pay, then contact that provider to discuss as some may have payment plan options that will help.
If you have online banking, you can schedule payment dates in advance. Set up all of your outstanding payments over a period of time that works for your budget, and is within the payment terms agreed with the supplier.
