** update on the PAT testing ******
As we suspected, all electrical appliances that we want to plug in at Brooklands must be PAT tested prior to the event.
The good news is that the PAT testing can be done by any properly authorised tester , the appliance just needs to have a valid sticker on it at the event.
So if you have a certified tester locally , you can use them
But if it doesn't have the relevant sticker on the day, it can't be used - which seems fair enough (insurance requirement I expect).
