That's what I love about Britain and the British.
So negative!
Right Davezilla. You were a bit vague on your background. Have you got any actual work experience? If so what? Domestic? Industrial? Agriculture? Maintenance?
Maybe try and get some experience in all fields if possible, give yourself a broad knowledge base to work on/from.
I also ask about experience so you you can be realistic on what to expect, be expected to do.
As for electrical courses, look into doing your 17th Edition next then possibly your 2391 Inspection and Testing (how academically smart are you?), or else leave the 2391 for a while till you gain a bit more experience.
Other courses or quals that may come in handy (though not for domestics).
IPAF (scissor lift and cherry picker)
CSCS Card
Compex.
Hope this has helped some?
Good luck and keep us updated
