I mentioned in another post that I would contact HSE regarding any issues reported to them arising from loss of neutral and EV charging points. They have responded and confirmed that there has been no incident reported to them. However, they were made aware of a small number of situations that were a result of poor or no load management. I should point out that this is HSE in Northern Ireland.
I only found one variation between the IET guidance and the DNO guidance.
The IET are saying that there should be 10 metres of separation between the consumers TT electrode and parts of the DNO TNCS-PME network, including buried service cables and extraneous metalwork, however Western Power and other DNOs say this can be reduced to 3.6 metres for single phase and 0.3 metres for balanced three phase, which makes it a lot easier to install charging points alongside a public highway.
