Question 1

The attachment to the existing clay pipe was made using a thick rubber
reducing sleave.
Looked like it was purpose made admittedly, secured with jubilee
clips round to both plastic and clay. Struck me as odd that the
fitting attached around the O/Dia rather than sleaving into the I/Dia
of the clay in the flow direction. Didn't see whether the plastic
slid inside the clay or not!
Is this rubber joint common practice?

Yes. This method is used by water authorities when replacing sections of
broken sewer pipe. They replace clay with plastic and join the new bit in
with these rubber couplings both ends. Ideally, the ID of the two pipes
should be very similar, and the pipes are butted more of less together for
straight-through flow.

Well even if there's a discontinuity there it'll get filled in and smoothed
by a, er, naturally occurring sealing compound


Question 2

How much should this cost including moving paving slabs, digging out,
refilling with shale and relaying slabs? The site is East Yorkshire.
Assuming that was all included in the 3 days maybe £600 - £900?

Haven't a clue! Didn't you get a quote *before* proceeding?
