Seriously, don't worry about it.....
Insurance companies are idiots. Remember this. Or to be more precise, believe that WE are idiots (and unfortunately there are a fair few in Britain! )
Firstly, anyone who renews based on their renewal quote needs their head reading. I have always got at least 33% off the renewal when going back to these company's websites and plugging my details in from scratch. Not ideal, but it saves the cash.
If you have an accident down on your record, that is no fault, no cost to the insurer, then clearly they have a dipstick as an underwriter.....
Have you tried the insurance traders on here for a quote? Elephant, Admiral and Diamond are all a pretty good start outside of them.....
