Has anyone successfully changed their career after 40 and is now working in a trade for example and is doing well? Or knows about services, resources, support in the UK?

Adults are allowed to participate in Apprenticeships. 

An Apprenticeship might be a route into a trade.

There are now 4 levels of Apprenticeship:

I'm aware that adults can apply for apprenticeships. It's just very unlikely to get an offer. Also, salaries are infeasible for me considering the cost of living. Only manageable if you're subsidised by family

But thanks for sharing anyhow!
