Will I be able to register a PayPal account once I register a UK company?

You can find more information about opening a PayPal account here: https://www.paypal.com/uk/business. 

Please note: We cannot guarantee your success in creating an account with PayPal, as we do not have a partnership with them.

Furthermore, we are unable to assist you with the application process, as PayPal is a separate entity from our company.
