You'd normally follow advice from this page, @JoeBloggs3:
https://community.talktalk.co.uk/t5/Articles/Home-move/ta-p/2205259
See if that works, or phone 03451 720088 [closes 7pm] or use Chat [closes 9pm] and ask for the Home Move team.
There are some situations where Talktalk doesn't have a service available at a new address. But it might just be a technical glitch.
You are very late booking this, however, so you might be without broadband for a few weeks.
If that's the case, speak to them about preventing calls going out on your old address.
If you take up the offer of a new contract when you move, you save yourself the £60 Home Move fee, but it's only worth it if you know you'll be staying in the new place for the duration of the new contract. So lots to discuss with them, and, as I say, you have left this too late to be set up on Saturday - it's also a Bank Holiday weekend, with Easter.
