Due to pilot flame, in 10P Bosch water heater,

Highly recommend a "plumber" that is different or new to you. Realize that if you must find one by phone, that would be much less desirable that going in person to the business and talking to the owner before hiring the job done. "Not all plumbers created equal." God bless your efforts.

I inherited a Worcester Highflow 3.5 GC 41-311-39.

It may well be a honey well which you can just change the motor . The top cover should come off 1 screw holding it and lift off you should see the motor there . Most plumbing and heating shops will stock replacement motors .

Bosch water wizard 16 - gas still runs after water tap turned off

Sounds like a flow sensor may be bad. It may be registering flow when there is none and it sending signal to ignitor and gas solenoid that there is.
