There's no age limit in England regarding the funding employers can access, I can't pretend it will be easy finding one though. If you want to get start the journey and acquire some relevant technical knowledge that would ultimately reduce the duration needed to complete an apprenticeship, then the TESP Routes on the Electrical Careers website show which qualifications count. An apprenticeship from scratch takes around four years.
it was quite good pay with the local borough council do council rewires before I moved to a private company to finish my apprenticeship. Then after 5 years , off to be self deployed / agency work. £10 ph
Short answer YES, according to your learning ability there are many other professions out there at the same intellect level that will take fewer years to reach a pay grade above that of an electrician, I am now going to my bunker and put on my tin hat.
It will be a pay cut, but I always wanted to build and learn a trade. I know pay will improve over time. For some reason learning a skill like this seems very valuable and worthwhile. I'm excited and nervous. Thank you.
