Looking for some advice if possible - NC for privacy!
I got a conviction for driving without insurance in October 2015.
It was a genuine mistake with regards to series of life changes when I moved houses - changed bank accounts to manage money better, let insurance company know but they didn't change it - all letters about the policy went to old address (even saying it I don't think I'd believe it because it sounds cliche, but it's true) 
I had no idea that I was driving uninsured until the police pulled me over, I had to go court, I cried in front of everybody and couldn't speak, the insurance company said they couldn't pull calls from when I called to change bank details even though they said all calls were recorded...
Anyway, long story short I ended up with 6 penalty points and a fine of about £300 which I paid off straight away, and accepted that it was my fault for not checking it had been changed successfully etc.
I am applying for new jobs at the moment and they ask about criminal convictions. I've tried having a look but can't find specific information about if I have to declare this now? Some advice says after 4 years it is "spent" some days 5 years..does anybody have any advice?
These are mid level jobs - admin / customer service etc not working with kids etc.
Thank you in advance to anybody who may be able to help!
