Upgrading for the duration of my existing contract?

[#1]

Hi,

Does anyone know if I can upgrade to fibre for the duration of my existing contract (ending October 2020), or will I be expected to sign up for another full term contract? Currently on £22.49 PCM for ADSL and I know cheaper fibre is available elsewhere.

Apologies for asking, but online chat and phone to Plusnet are both out of action currently. 

thanks in advance,

Ben.

Not 100% certain, but 99% sure a product change like that would be on a new contract.
