If you have let them in before, and they did a valid levy, (list of possessions) then bailiffs have the right to return to your home and if you don't let them in, they are allowed to break in.
Contact the bailiffs straight away and make an offer to pay the debt in instalments. Show them a copy of your personal budget so they can see you are offering as much as you can afford. You will need to treat this as a priority debt as bailiffs could come back and take any goods they have listed if you don't pay. Get a receipt for any payments you make.
Contact your council and ask them to take the debt.
