Adrian Flux for house and Aviva for car( Aviva didn't want to know about my conviction for my car insurance when I told them they said it wasn't relevant to the policy).
This works for me and is the most competitive way of doing it [for me].
Next year its been 5 years since my release so I can try LV for my house as I am told they don't count convictions more than 5 years old.
Don't know if they will be cheaper but another quote is always welcome.
Just as a tip, I always ring direct and ask first if they will cover me with my conviction before I even give my personal details such as full name and address. You would be surprised how often that works and saves embarrassment and giving info to a company that will turn you down.
I asked this of LV and that's how I found out about the 5 year thing without telling them who I was then when I come back to them It wont be a problem as they will ask if I have any criminal convictions in the last 5 years and I can say no
