Just so you don't think I once changed a plug socket and then thought I was handy enough, here are my qualifications.

I worked for 22 years as an engineer in the RAF.
Engineering uses transferable skills like fault diagnostics, pneumatics, hydraulics, materials manufacturing,
fabrication, multi-tool use, working from blueprints, people management, project planning, stock ordering etc.
So not only can I compently plumb your toilet, I can refit the light, hang a mirror, change the skirting and build you a bench seat.

I don't do Part P electrical work - you'll need a qualified electrician for that, but I can change lights, sockets, oven elements etc.

I also have qualifications in Money Laundering, Change Management and Prince2 Project Management after leaving the RAF.
I found I preferred diagnostics and fixing to desk work, so to utilise all my skills, I became a handyman.
