Did you need licensing / training to take on electrical work? Do you market yourself as an electrician or more just a handyman that does minor electric jobs?
I got my license in my gap year before uni a long time ago; it's not valid here, but in my country I got trained with a lot higher standards than where I live now so I can do anything besides actually hooking stuff up to mains. I helped some people out and they told others. Like said; there is a massive shortage of handy people and as this is not my day job, I have to say no a lot.
