You are correct but from my experience when I was visiting UK in 2008 you get charged with extra fee it was ~2% if you want to use the credit card or it was no extra fee if debit, so I was advised not to use credit card. Now I don't know if it was only specific places like aldi/tesco since I've only been there few weeks, and only to those places. Also cashbacks are not a thing even in 2018 in eastern europe at least, you can get miles, loyalty points, but not cashback.

Such a surcharge was banned in the UK in January 2018. Now vendors have to accept all forms of payment they accept at no additional cost to the consumer.

Here in Lithuania we have this since ~2013 or maybe even earlier, that you can't charge lower price because of the payment method. But to get around that law vendors here give discount, i.e. you are not banned from saying - we give x discount if you pay cash.

Although I stopped seeing it lately so I guess it was banned as well, most shops started rollout of their own or joint loyalty schemes with points, and they are very clear on that points are not money but x points equals certain amount of discount, which is funny to watch but it is essentially a loophole around this law once again.
