Good morning Howard (Turner210340),
Thanks for getting in touch and welcome to the Community Forum! I'm sorry that you've had this problem with your Hub.
As Andrew-G has kindly advised, it does sound like you will need an engineer visit so that we can look at this Hub fault. I'll just need to confirm some details with you via private message. Please look out for a purple envelope in the top right corner of your screen.
Kind regards,
Laurie
