There are pro's and con's with each earthing arrangement, but I'm convinced that mixing the means of earthing in small curtilage properties, and many other installations such as those dealing with explosive atmospheres, buildings with lightning protection systems, etc, is simply not a good idea.
And, of course, EV installations! Pity that message wasn’t relayed to City and Guilds for their 2919 course which has the conversion from TNCS to TT front and centre of the assessment.
There are still many charge points that require an earth rod and I am sure end up installed in built-up areas with PME services.
