I have some original @btinternet.com addresses from many years back - well before they differentiated between business and consumer. I have always used BT as my ISP and have used BT Business for many years whilst keeping the @btinternet,com addresses for the occasional emails.
Two years back they informed Business service users that they would start to be charged for keeping the addresses - I raised a complaint that had an impact - they paused charging for 12 months until mid 2015 before implementing the £1.60.month fee. At present they have not informed me of the rise - will it stay as before or increase? I'll wait and see.
