I read an article this morning that some establishments are no longer accepting the paper 20 and 50 pound bank notes even though they don't go out of circulation until end of September. I've got about 500 pounds worth of them that I had leftover from a trip to England in 2018 that I was going to use for a couple of B and B's that have advised me that they're cash only. I've emailed them to confirm if they'll accept the old cash.
I thought the simple solution would be to head to the Royal Bank of Scotland when I arrive next week and exchange, however the website says they'll exchange for their customers only. I'm curious if anyone has experienced this recently and can advise?
