Thanks for posting this question on our forums, I understand you're wanting to relocate your Hub to a new space in your home.
We can get this booked in for you, as the other users have already alluded to, this will have a small call-out fee of £25.
They will only be able to relocate your Hub, they wouldn't be able to install anything your your ethernet cable as this would be down to DIY.
I can also see that you mentioned an engineer visit that didn't materialise, I would be happy to check this for you as per our compensation scheme.
As for the connection issues that you've been experiencing, I can see that there is an area outage today which may be causing some disruption, the engineers are due to have this fixed at 4:00pm today.
I'll send over a PM now so I can get your equipment relocation booked in.
