Moving house and getting an engineers assessment for connecting

Have had a discussion with the chat support team about having an engineer look at connecting a property we've purchased (but haven't moved in yet). Have been given an engineer reference, but have recieved emails telling me they're 'Sorry they can't connect us' within an hour of me talking to the chat support team.

Are these automated emails that are sent out anyway? We were advised that they would start the cancellation process automatically and then re-instate it once we can get our new home connected (if it's possible), so just trying to get peace of mind as the other connection options in the area are pitifully slow.
