think seriously whether this is what you want to do mate. if you want to be a sparks, then the only avenue open to you without spending 4 years in colleg, is the quick courses open to you at the resettlement centre in aldershot. They will only give you the very basic skills on domestic work.
this area is flooded with labour at the moment, because of the advent of the quick courses. Also in the next few years, the governing bodies of our industries are ensuring that anyubody with the responsibilty of signing their own work off, is qualified to NQF level 3 as a minimum. The quick course will not give you this.
With the quick course, it is almost certain that you will not get work as an electricain, unless you work for yourself, or are lucky and get in with a one man band who does only domestic.
im sorry to paint such a bleak picture, but the construction industry is really suffering at the moment, and domestic is suffering the most, as people havent got the money available to renovate their houses, and to them, the electrics are not a priority (how wrong they are).
Good luck mate,
John
