Crikey. Well as I was inside the house, I only saw it through the glass in my front door, so probably it wasn't strictly "ball lightning" as such. It certainly wasn't moving about!
And if it struck Alleyn's, it can't have been in two places at once.
But as I said, it "looked like" there was a huge ball of light outside in the road.
I was very glad I wasn't standing outside, put it like that 😂
My partner heard the bang in Surrey Quays!
