Hmrc and addresses

[Bananafred]

So I have a stealth eBay if 10 years now , but my worry is that
My eBay address and name doesn’t match my HMRC registered
Info . Would this be an issue or considered fraud ? Also my last question
If I was to hire an office , with my real name BUT office address and bank with my office address, would this get flagged ? If everything is new apart from my name ?

Can you be a bit clearer with the question, I'm not following 100%. Im guessing others aren't either by the lack of replies.
