Yeah unless you greatly like driving, then i'm not seeing that as a great option.
Personally i'd be spending £4-5000 to train as a plumber/sparky and then work for myself. Heck even half training as a sparky and doing PAT testing would pay more than that. You could do worse than have a chat with Couchie about electric vehicle installations for chargers etc which he's clued up about as that's a potentially good plan IMO and i'll bet my arse it pays more than £9.50.
