Number porting timeframe?

[#1]

Hi guys,

my BB and phone contract is coming to an end but want to move to full fibre and port my existing number to a Voip service. Do I have 31 days after moving to full fibre to port my number over under new rules? Not sure how it works and if I need to notify PN or will the Voip provider sort everything out (voipfone or everydayvoip)?

Thank you

Judging by this thread https://community.plus.net/t5/My-Order/Unable-to-port-landline-number-after-signing-up-to-Full-Fibre... it doesn't seem to be working very well

Seems like a complete farce lol

I have notification of my new FTTP installation date and they recommend (Aquiss) to leave a couple of days over lap of previous connection which is fair enough, but if I port my number over after this will it terminate my contract (currently now on monthly rolling) or do I need to give notice to Plusnet?
