Basically it's quite easy, 

First join the IET as a Technician Member (TMIET)

Then fill in the application form for EngTech, which is just listing your training and qualifications, and saying what you've done at work. The easiest way is on the IET's CareerManger part of the website, which you can get onto when you are a member. Send it in and that's it.

BUT there's the clever bit, which is the "saying what you've done at work", when you write this you have to show that you understand what you're doing, that you do it safely and thinking about what your employer wants (including making money!), and generally working professionally. When you get to writing this it's best to talk to an IET Professional Registration Advisor (it won't cost you anything) who can talk to you about what you do and can help you get your words right. 

To be honest, if your employer trusts you to do electrical design and plc programming for the railways you should have no problems.

Cheers,

Hi,

This is process is pretty simple as I've just done it recently and the post above explained it as it is. I'd also advise you claim tax back on the gov website for professional memberships on it as well.

Irrelevant to the question though, I'd like to ask how you progresses into electrical design and programming? I'm currently an electrical technician on shift after completing my apprenticeship and now I'm looking to progress further into more specialised roles such as design and plc programming etc
