Probably a blockage between the house and inspection chamber - at worst a collapsed drain.
To find out for sure the best bet is to get a camera down the drain alot of companies offer CCTV inspections - this will tell you exactly what's causing the problems.
I would, lift inspection chamber cover and run bath any water appearing in chamber ? no water or very little I would get some drain rods down to see if this'll clear the problem, if it doesn't you either get drain people out to assess - or start digging and check the drain yourself (which is the route I chose, I dug down and found a collapsed drain)
Always rod away from the house towards the chamber, never rod back up as all you'll do is compress the blockage and push it further back.
