Is Zencart compatible with PayPal Website Payments Pro UK?

According to paypal it is compatible with Website Payments Pro US:
https://www.paypal.com/en_US/html/So...wp-pro-us.html

but it is not listed in their UK section:
https://www.paypal.com/en_US/html/So...wp-pro-uk.html

Does anyone know is there a big difference between US and UK versions?

Thanks for any help with this.
