Not if the client says that they don't want one.....it's only a recommendationNo you install one , you don’t recommend!

i dont agree with that? Your suppost to eliminate the car shell becoming live should a open PEN conductor occur not wait for someone to have a shock and hope the rcd trips which it wouldnt with the loss of neutral conductor!
If the Consequences caused by overvoltage for a single dwelling unit where an assessment shows the total value of electrical installation and connected equipment is found to necessitate the cost of SPD protection then you install one, you don’t fob it off as the assessment will have been done with the client.
If it’s found it’s not required then yes don’t install one.
I install them as standard in domesticGiven that separate Type 2 SP+N SPD can be bought for under £100 and you can get whole CU with them already included for around £100-£150, why both with the risk assessment at all?
I suspect doing it properly and documenting it for the client is going to cost more than £100 of your time!
No spd required.......it's only a recommendation to have one and I believe you have to do a course to get a qualification to fit car chargers
Why do we have RCD at all then?
RCD are fitted so there is no single point of failure that leads to a dangerous situation. They are not a substitute for proper insulation of conductors or earth bonding of metalwork, but are there to deal with cases when something unlikely but possible results in a dangerous situation (e.g. open PEN conductor, garden tool cuts extension lead, etc).
True if you lost the majority of L-N voltage it would not be able to trip but I suspect you would see a fair portion of 230V remaining due to the other phases' loads. If designing something like this from scratch you would probably have something like the Matt:e box contactor that would zero-volt release under such circumstances, and possibly only close fafter doing a self-test cycle.
On investigation found the earth rod on the house supply had a sheared nut in the earth pit leaving a very high earth loop.
