Engineer visit or not

[MarkyMark247]

Hi, I'm going through the sign up process and have just discovered that an engineer visit 'may' be necessary.  But it also says that if I have an active connection it shouldn't be necessary.  How do I confirm?  I don't really want to wait in for an unnecsssary engineer visit.  Is there anyone I can contact to confirm this?  May not purchase if a visit is necessary.

If it's in the UK, putting the address into the BT Wholesale Availability Checker should indicate which broadband provisioning type is applicable.

It's the table and the two text lines below it which are most useful.
