Switchover delay and potential downtime worry

Hi, I was with Vodafone FTTC 74mbps for 1.5 years then recently decided to try Talk Talk, all went well for the switch but my speed went down to around 50mbps - I ran a speed test on ny next door neighbor's Sky and she is getting 74mbps and so I decided to switch again to Sky before my Talk Talk cooling off period ends. I ordered Sky and they gave me a switch date of 19th December. Then last week I get a message from Sky saying that Openworld has informed them that there will be a 'delay activating my service' - Now I am afraid that my Talk Talk service will cease and Sky won't be able to reconnect me? . . . I called Sky but they essentially don't seem to be able to do anything except read that message to me about the delay - Can anyone please help with some advice about how switchovers work - would Openreach just switch off one active service without the replacement being available or would Openworld delay the entire switchover? I am very worried about potential downtime . . . . This Switchover was supposed to happen in 3 days and I haven't even received a router from Sky yet either . . . thanks

Migrations usually take a minimum of 10 days due to the Ofcom 10 day notification period.

For a migration Openreach will leave the old provider connected until the change to the new ones happens, its more will TalkTalk turn off your account on the planned day of the move.

When you say speeds went down, are you referring to speed tests or the connection speed reported in the router?

Hi, thanks for the reply, when my Talk Talk went live my sync speed (in the router panel) was about 54mbps and speed test just below that, but now my sync speed is 72mbps but speed tests never get higher than 59mbps. I am not really complaining about that because it's a reasonable speed. My concern at the moment is whether Openreach might cease my Talk Talk without the Sky being ready to take over . . . another slight concern is that if Sky do take much longer I might then be outside of the Talk Talk cooling off period and they might try to make me pay penalties for leaving (although I did initially sign up for Sky which I am told is the cancellation procudure to Talk Talk, was within that cooling off period) . . . I have checked my Talk Talk account and it looks normal (no mention of an up and coming cancellation) and did an online chat with Talk Talk and thy told me that they don't yet see a cancellation request from Openreach but as I don't know what the actual switchover procedure is, ie: whether Openworld will switch off my Talk Talk on the 19th without a replacement being ready to take over leaving me with no broadband - that's my immediate concern . . . . Can you please also tell me what the Ofcom 10 day notification period is? Does that relate to me being notified (so that I can prepare or change my mind?) or Talk Talk? Thank you

Signing up to Sky should have triggered a migration notice, which triggers a sorry to see you are leaving message.

So if that notification has not arrived from TalkTalk and then claim ignorance suggests Sky has not placed a migration order yet.

The 10 day period is the mandatory period from when you get the 'sorry you are leaving letter' to respond and say you do not want to leave, i.e. stops a friend pranking you and moving your broadband service.

Thanks for your help, I still haven't heard anything from either Sky or Talk Talk much appreciated
