How can i create or buy a domestic return shipping label for my buyer in UK? i am not living in UK

[dakbat-61]

i have got a return request from my buyer whatever the reason which is completely welcome and i am fully okay with it i have no problem at all.

my question is 

i have a UK address that i can receive returns but how can i purchase or create a shipping label online through the UK royal mail?
because it's my first time return over there and i don't know how to handle it 

i ask my buyer to ship to an address in the UK but he is not willing to do as long as i didn't provide a shipping label which i have no idea how to do on a distance?
if anyone can help i will greatly appreciate it 

thanks
