Soft credit search from betting website?

[shavingface]

I've just checked my credit score and noticed a few months ago that Bet365 did a soft credit search

It says:

GB GROUP-BET365 NON CREDIT
Search for Id Check By Other Public Sector

I've never signed up to Bet365 or any other betting website, never placed a bet in my life.

Should I be worried? What do I do?

Strangely i had this too, I'd assumed my ex had used my details for it as i know he gambles using that site.
But a soft search can't be seen, right?
