I gave up trying to find out whether Email forwarding from my ISP was available or not, and didn't want to sit on the phone for half an hour waiting to speak with someone.
I looked at what I am wanting to do from another angle and have found a solution.
Using Outlook.com there is an option to send/receive email from another account - including pop3
Very simple to setup and will do the job nicely. Send and receive email from other accounts in Outlook.com - Microsoft Windows
Thanks DavidW7ncus for pointing out the flaw in my original thinking!
