Toilet Blocked - Fills Up when Toilet on Floor above flushed

Ok, check again for any manholes, also what is your postcode?

Need to find a manhole. Cant imagine its far away, as the gully must run separately to the sewer, otherwise I'd expect that to be full and overflowing.

Ok, there is a furnco coupling, which means someone might have drilled a hole in the stack for access.

See what looks like a manhole cover outside my house in the middle of the road.

Work was done about 16 years ago by insurance company to fix underground leaking pipe

Above the Fernco is still cast, I suspect someone's fitted the Downstairs WC at a later date and grafted a connection into the original stack. Might be handy though if you need access, and better than attempting from internally!

Once any drain/sewer passes under your boundary and/or becomes shared with another property, then it becomes Thames Water responsibility.

So should I contact Thames Water?

Whereabouts is the stack you've pictured? If on the rear, I'd expect a chamber somewhere, unlikely it would run under the house, out to the road without any form of access along the run. Thames could be worth calling, but if only you affected, they may throw it back as Private and your responsibility.

It's on rear....but do get feeling Thames Water will throw responsibility back at me

Looking at Google Earth/Street view, if you're one of the 'Odd Numbers' then there are no visible Manholes in any of the frontages of the properties, and no evidence to suggest any bathrooms etc on the front. I would therefore suspect you have a common main sewer running along the rear of the houses, but given the gully is not overflowing, I'd say the problem is fairly close to the building.

If you're feeling brave, undo the Fernco coupling above where the downstairs WC connects into the vertical stack pipe, and poke some drain rods down there, might strike lucky. Otherwise, you'll need someone with Jetting gear to have a go, have you spoken to Andy at Herts P&D?

Appreciate your effort in looking at Google earth. I am an odd number. You are right - my insurance company told me I had a sewer somewhere through back garden. Had issues with tree roots damaging pipes 16 years the insurance company fixed.

Andy was checking my post code to see if he covered the area.

An extra bit of information - Soil pipe to the right in picture is from toilet in extension and that works ok

Are you a terraced house?
