The price of bills is always changing, so it's better to put away a bit more than you think you'll need just I case it does go up, so you will hopefully be covered. You should have an emergency fund saved up to cushion the blow further.
Afaik if you use internet banking you can open as many sub accounts as you want to organise your money and not have your cards be able to access all of your money at once. You should be able to Basically split your bank account into multiple accounts to make it easier for you to organise your money. I have an account for spending, short term savings, long term savings, mortgage, house bills and personal bills. Before any expenses come I already have the money ready and I haven't had to worry about a bill in years.
This comes after some time of financial planning and saving, so we may be in pretty different circumstances if you have just been hit with a bunch of bills and don't have the money to pay all of them, but you might be able to take this as something you can set up when you're done qith these bills. Most places can help you with a payment plan if you don't have the money to pay them right now, just be careful not to get too deep I to that or you can get stuck in a dept spiral which can fuck you for a long time.
