How do you intend connecting the new W C into drain?
I plan on cutting into the existing clay pipe before it enters the inspection manifold and coupling it to a pvc underground pipe which will collect the waste from the new toilet and existing bathroom utilities.
In that case inspection chamber will be fine, make sure you connect to existing preferably with a Y type connection and you will need to provide some sort of rodding access.

All Drainage needs to be accessible for rodding/jetting in the vent of a blockage, making a blind connection to an exiting run is not allowed. Any run from a WC will need to connect to the existing sewer by way of an inspection chamber.
Your best bet would be to find the existing run nearer the property, (I assume it's going to a Gulley currently?), cutting that back, install a chamber and connect the WC and wastes into that. Hopefully the existing sewer has enough fall through that chamber to carry the solids through without issue.

Thanks for the replies, the waste is indeed going into a gulley next to the property currently.
What I plan to do is have all the waste connections sorted above ground and then swap the existing clay underground pipe with a new PVC one so that just one pipe goes into the chamber with no underground splits.
There is an existing join in the clay pipe a foot away from the chamber so I should easily be able to swap over for some PVC pipe with the correct adapter.
