Can you see the picture I have uploaded as it shows what box I am trying to enter a valid BT ID to complete the test?
It wasn't coming up on the thread @Orient, but I've been able to see it on your profile.
It isn't asking for your BT ID, it is the Broadband Service ID, which does start BBEU.
That would usually be on any emails or letters that were sent to you when you took out the contract, but if you don't have that available, it would be best to get in touch with our broadband tech guides, who can get this for your reference, and also take a look at your speed for you.

Thanks for getting in touch with our team @Orient.
If they're not able to provide you with these details, then as an alternative they should still be able to help run any checks on your broadband connection if you're having trouble.
As an alternative, if you log into the My BT app, there's the option to test your speeds and run further diagnostics in here too.
