When we had low voltage issues UKPN came out the next day. Engineer downloaded data from our smart meter which apparently contains a log of voltage, and confirmed the issue (I also had data from our inverter).
He then went off on search if the problem and called back an hour later to say he'd found some kit burnt out in a local substation which was affe ting vintage control. All fixed.
I was impressed.

Actually my Tesla charged very slowly and stopped altogether a couple of times on Friday night due to low voltage. But then I saw on Facebook someone complaining that the power company was out with a chainsaw that night, so I guess they were doing some emergency work and put us all onto one phase or something. Will be charging tonight so fingers crossed all sorted.
