I have booked my installation for this Saturday and just get the text message to set a time for the pre-installation survey during the week.
Do I have to be present for that visit? I live in a high-rise with no doorman, do they have to get into the house / my flat?
Welcome to our community and thanks for your post.
This isn't something you would usually need to be home for, they'll be checking the junction box outside and to ensure there are no blocked Tee's outside.
