Cheers for response lads, tried manor way, swanscombe, not comfortable with there to be honest, so managed to get to the back of this Halfords on the estate in Gravesend, it’s a turning yard with access gates to a bitumen plant I think. Anyway ended up having a word with jobsworth security, he reckons tankers in and out from 3 and they ‘may’ wake you up especially if you’re in their way!!
OK its probably private grounds, I was well tight enough against the back and side walls, thought better of getting horned at 3am.
After all that managed to find a spot outside screwfix round corner, no double yellows, if anyone needs this info for future reference.
