Is this just a poor line? (Line stats inside)

I've been trying to help a family member troubleshoot slow internet, started with these.
ISP is sky, using their stock hardware.

Not a very fast connection...
Looking to improve it anyway really?

Sadly no bell wire to remove.
2 year old house on a new estate, typical great planning there, no fibre available yet.

Thanks for the insight all!
