You probably will have to pay early termination charges....no provider will put your account into abeyance waiting for you to resume service elsewhere , if you knew you were likely to be moving out it probably wasn’t a good idea to start or renew with minimum term.
If you don’t advise your provider,( hoping to continue to pay monthly even though you won’t be able to use the service ) there is every change that whoever moves into the property you are moving out of, will apply for service themselves, this will automatically close your account ( if you haven’t moved it somewhere else ) if , for some reason they don’t use an Openreach provider , then you may be able to postpone the inevitable, but would you want others using a service you are paying for ?
