What qualifications do you hold if any?
You hint you are not from the UK, where are you from and do you hold relevent qualifications there?
Unfortunately having a little experience and interest are just the starters to getting into any part of the industry although you could apply for a basic skill level job like vending service and repair where you are normally trained in the job but this won't be of any benefit if your looking to get into industrial and machine service and repair, you would need to do a few core qualifications to go that route and this could see you taking courses for several years with an apprenticeship before you would be classed as competent then I would suggest a further 5 - 10yrs experience if you wish to go alone.
You will need to learn several BS regulations covering Electrical installation (BS7671) to Machinery control standards (BS60204) and others depending on which particular field you wish to work in, if you wish to alter or design any control system then you will need to learn how to do risk assessments, design safety critical systems, implementing them into new and existing controls. Looking from the outside in it does look a very ineresting and appealing career but its a very steep hill to climb to be competent, its not just about replacing blown fuses, burnt out contactors etc... you need to be able to read the circuits, understand them and know why equipment has failed and what if any measures to take to avoid a repeat of the failure.
If you are still set on going into this career and you have the dedication, patience and can find suitable courses tied into apprenticeships then go for it and I wish you well, if all you want to do is replace damaged plug tops and cables etc then there are simpler routes but you will never really earn a good salary nor have a recognised title in the industry backed by core qualifications.
The younger you are the better due to the time it may take to get any level of competence, also existing qualifications in related industries would be a added bonus and may head you in certain directions so you could benefit from what you are already trained in.
Without the Diploma's etc then you won't really be anything more than a Engineers/Electricians mate.
