not so much an electrical company, but have a look into NETA, they take on around now, i went there to do the first year training of my apprenticship and loads of companies go through them, and i mean loads, we had people who worked for companies in wales and sheffield both coming up here and there company paying for housing up here for a year while they do there training.
when you joing NETA you do a test and they send the results to companies and companies say yeah we want this guy we want that guy bla bla bla so if you apply to NETA they will no doubt set you up with a few companies.
good luck
