Someone registering a company to my parents address!

England: Someone with a construction Ltd company has registered it to my parents address and my parents have been receiving multiple bank cards from the likes of Monzo, Tide etc.

Is this part of scam they need to be aware of?

I have suggested to my parents to check their credit online and they’ve contacted Companies House to get the address removed which they are going to do and I believe they’ve returned the post/bank cards as return to sender not known at the address, anything else they need to do or be aware of?
