I find my insurance has since quoted about £100 more since the crash

All insurance costs have risen over the past 12 months.

Recently renewed our 2 car policy. Aviva wanted 23% more for this year (£116) than last and there were no changes whatsoever to our policy and there had been no claims. Did the usual round of interweb quotes and none were less than Aviva. So I phoned Aviva and asked why it had risen so much and made it clear I wanted to stay with them, they came back with a price 12% higher than last year.

I suspect a good proportion of your rise is due to the current cost of living crisis and not your no fault accident.

The last time we had a no fault accident the renewal cost was lower than the previous year with the same insurer yet people on here insist it will always affect your premium if you claim, nonsense.

For the record our home insurance (Aviva again) rose by a similar percentage and when I rang then they again halved it with no hesitation.

The last no-fault accident we had involved the wife who was hit up the rear whilst stationary in August 2017. The damage required a new tailgate, bumper and other works, seem to remember the total was about £2500. Reluctantly the 3rd party driver admitted liability (he initially blamed the wife for not indicating - she had to make an emergency stop - who indicates?) but according to this forum premiums still go up since you are a greater risk. She paid £197 in November 2016 and when the renewal came in November 2017 she paid £185 for exactly the same cover. Her NCB was protected and the excess was recovered by our uninsured loss policy.

Dad had an accident in about 2013 which was totally his fault and he was the only car involved. Repairs cost about the same as the Note but we expected his premium rising not because of any loss of NCB (it was protected) but because of his age, he was 85 and obviously a higher risk. As with ours his premium fell slightly the following year.

You need to find a different insurer.
