Massive plus vote to that advice.

Done a recent migration away from Sky and made no contact at with them and once all done and dusted the excess rental paid was returned as a credit via direct debit.

Followed everyone's advice. BT terms seems to suggest if i contact them it is a 30 day notice period but if I go through another ISP it is only 14 days. I placed an order for switch over to Plusnet (only) beginning the 10th and already have received an email from BT acknowledging the switch over and advising all the things I would lose by leaving them.

The notice period is started automatically when the new ISP submits the migration request. 14 days is the statutory minimum period so the losing ISP can write to the customer. The main thing is, you get a refund from migration day onward.

If you so much as contact BT and ask for the account to be closed, or to terminate your services, what happens is they place a cease on your line. This effectively closes down the existing line. The cease date is usually a week or so in the future.

The new ISP is unable to take over a line with a cease in place, so they have to wait for it to be terminated. You then have no internet or phone line.

The new ISP then places a new order on the ceased line. This often takes 2 to 4 weeks. During this time you have no broadband.

This is why we keep saying do not involve BT until the plusnet is running.

Users end up with no service because they ask the existing provider e.g. BT to close their services, and then go to the new provider and place an order, what they do not realise is that BT have already marked their line to be ceased.

Glad it's working well for you. BT should also inform you of all associated charges if applicable if you are still in a contract term.
