Just joined Sky Talk Unlimited with TV and max broadband.

I just moved into a new build property that has openreach connecting new line next week.

How do i request/pay/set up to choose/select a tel number with BT/SKY that is more memorable one than one allocated.

Do i sort before Openreach come, after - and who do i speak to. Is there a fee and any tips on how to sort with someone...

thanks
