Moving Router to another room

Hi, i have recently signed up after moving home and wanted to have the router installed upstairs where it could be used via ethernet to make full use of the gigabit bundle i have signed up for. Unfortunately when signing up i was told there was no longer an option to have a technician come to install the router.

Is it still possible to have someone come out and move the router? The  wifi speeds are very low in most of the rest of the house and even a powerline adapter hasn't helped much.

Any help with this would be appreciated as the bundle isn't really worth the cost as is.
