I have found square payment option and have questions Paypal or Square

I have found square payment option and have questions PayPal or Square.

I have a UK Square account and it charges 1.75% and the first £1000 free of charges. Which can be renewed if I find another joiner for Square.

I see the rate appears for the UK as 2.5% does this still apply since I am have the free £1000 and 1.75% thereafter?

I am using PayPal at the moment and it does not appear to charge anything or am I wrong, if so where do I find the charges?

Thanks for your help.
