Btw the pipework had already been previously done by a plumber, it was there ready under the joists ready to be cut to length and have the trap fitted.

Sorry if I'm being a bit thick here, but the waste pipe was already installed , just waiting for the trap, and this guy jumps in an notches the joist like that without even checking for it? That's reckless imo and he should pay for remedial work.
In the BS 5268 code there are equations for calculating the allowable stress at notches near the end, for any grade of timber. As this is a permissible stress code, allowances are built-in to ensure that the timber is not over-stressed at the notch, whatever the grade.
BS5268-2 section 7.3 Machining and preparation; Care should be taken to ensure that notches and holes are not so positioned in a member that the remainder of the cross-section contains a knot or other defect which will significantly affect its strength.
But considering a whole length of timber statistically, I wouldn't have thought that a short notch would affect the grading, regardless of the depth of the notch
