This substation fire is nearer to where I live than Heathrow.

Woke up around 1 am to discover we had a power cut. Helicopter overhead, no mobile signal, no way of finding out what was going on.

Eventually mobile signal returned and called 105. Recorded message informed me that there were 67,000 homes without power from Northolt to Heston, and power expected to be restored by 3 am.

For a few moments I thought Starmer had nuked Moscow.
