    How is 0.2s disconnection time met on TT?

    That's incorrect. RCDs don't operate on line-neutral faults, only earth faults.

    Are further qualifications required to install an EV charger?

    My advice would be to buy the iet code of practice book that walks you through what to do. I did the course and it was basically reading through the book. If the customer is paying in full, no additional qualifications are required.

    UK Rewire using old conduits

    Ring vs Radial : Identification.

    You're correct, the only way is to disconnect the cables and do and end to end continuity test. It is permitted to have 2 ring cables and a spur cable in one circuit breaker, so long as the termination is secure. It's the same as spurring from the ring final circuit at any other point.

    Does this need to be bonded?

    By standing on the soil you'd probably be wearing shoes that provide some level of insulation. Touching a metal pole with bare skin will give a lower impedance to earth. Also it would be a case of resistors in parallel so the two paths combined would give a reduced total impedance to earth.
