I was in a similar position to yourself a few years back, even having an electronics HNC. Your lack of a degree is not a problem but your age might be. However, so much of it is all down to luck in being in the right place at the right time. It worked out for me, in spite of being older than you. It might do for you. Give it a go if you have the finances to be able to afford to take the risk. Be warned though, I had to take a pay cut for the first couple of years. Good luck!
