Payment method for Electricity / Gas / Internet bills in Poland

Hello guys and girls :)

What is the normal payment method in Poland,
when you are paying for your bills.

Is a "polish" bank account necessary, so the providers can charge from that account.
Or are there possibility's to pay with different payment gateway like in UK / Romania with "PayPoint".

Thank you in advance!

I'd reckon the vast amout of people pay bills through their banks with transfers.
With things like utilities though you can pay them in your local post office too.

I'd get a Polish bank account if I was you, just to make things easier.

@smurf: Thanks for the answer! Is a Polish bank account needed, or is a other European Account also working?

I know that some Countries in Europe need a "direct debit authorization". Which only works with a interior Bank account.
Like Germany for example.
