Picking install date for new line

According to the talktalk support online chat if i order a new phone line i can pick the install date.

Has anyone on here done this recently and is this correct? I ask as apparently you cannot pick the install date with sky...

I know someone who recently managed to choose an install date for a new line on TalkTalk Business so no reason why the same can't be done for their residential service.

This is true but beware. They've failed to turn up twice now to install my brothers broadband and we're not waiting 10 working days for a response from the CEO team as every other level of support cannot help.

9 weeks and counting since he ordered!

The installation date for an appointed order is determined by the availability of Openreach engineering workforce in your location at the time.
As for attendance on the day, this also is a dependency on the engineer, or alternatively the quality of the data passed to Openreach during the sales process (i.e. correct address).
