The UK is currently in the grip of a fraud and scam epidemic. In the past two months scammers have launched an avalanche of scams, and some of them are extremely difficult to identify as such.
One of the best sites for checking a scam email is this one (https://www.which.co.uk/news/article/the-latest-scam-alerts-from-which-aBRLy2b02WkC).
Stick to the basic rules when receiving a worrying email:
1. Never, ever follow a link in an email. Ever.
2. Always ring your bank using the number on the back of your bank card. Never, ever ring using a number suggested to you in an email or by a caller claiming to be from your bank.
Some scams are particularly nasty (https://www.which.co.uk/news/article/job-scams-fraudsters-are-posing-as-employers-and-recruiters-on-indeed-and-linkedin-a7NNv8L84n97).

Sadly, we live in a world and at a time when you cannot trust anyone without verifying they are who they claim they are.
Stay safe.
