I cannot see anything in the wiki so maybe someone can tell me what I
need to make a new connection from a 40mm plastic sink waste into what
gully trap and thence discharging into an existing foul water inspection
chamber?

Also is the work building regs notifiable

Not if you do it properly.

Just core drill into the inspection chamber so that
the hole is above 'high tide mark' and seal with
silicon. Make sure you have a downfall, but not too
steep all the way.

The trap under the sink will provide the necessary
smell trap.

Sounds too easy, I was assuming there would need to be a separate gully
trap outside before the connection to the inspection chamber.
