Actually, when we contacted the power grid about our high voltage, the guy that turned up did say the opposite (eg low voltage) was stopping people charging their electric cars so there must be some truth in what @jigger is saying.
(Heads up)UK National grid looking to start lowering voltage.

I touched on it in a post above that some EV chargers have a low voltage cut off of 210V - which could cause issues though it would probably be more of an on, off, on, off nature than just straight up not working at all, which isn't ideal for charging. Some places though may be seeing voltage drops due to fault conditions below 207V even i.e. brown out stopping them charging rather than it being a drop to the minimum regulated voltage.
No idea how it would be affected at 207V but even the cheap Cookworks microwave I have in my "mancave" so to speak works fine down to around ~216-217V we used to see sometimes when people first started buying EVs around here before they did upgrades to the incoming supply to the village. (EDIT: Though I suspect that was partly solved when more people started adding solar panels to their houses around here which are likely grid feed).

That's because the charging equipment is designed not to charge the car when the voltage is out of range because it (correctly) assumes the grid is in a fault condition.
Obviously if you change the grid voltage range, you can re-program the EV charging equipment to work with the new voltage range. It's also worth mentioning 207V is already the low voltage threshold across Europe and it is the UK which is the outlier.
Maybe some users/manufacturers could. At least the manufacturers that still offer support, but many are no longer in business.
