Just to add, it’s human nature to find the cheapest price for car insurance. It’s not always the best option to go for the cheapest though; quality of the claims service is an important factor IMO should the worst happen.
Many years ago, I was the innocent victim of being rear-ended while I was taking my car to the garage for it to be serviced. Exchanged insurance details with the other driver (they were insured with some obscure Lloyd’s of London syndicate). Contacted my insurer, and got the garage to provide them with an estimate, which the insurance company approved and repairs were authorised. My car was repaired and ready for me to collect a week later. IMO that was pretty good service - both by the insurer and the repairing garage.
I had to recover my excess from the other party so my NCD could be reinstated, and had some issues doing this so resorted to using AA legal services (I didn’t have the legal expenses optional cover under my motor policy, but was a member of the AA at the time). I received a cheque for the amount of my excess from the other party for the amount of my excess, and I subsequently discovered they were still waiting for authorisation to get their car repaired - from memory, this was 5-6 weeks after the accident!
Apologies for the long-winded story, but the old adage ‘you get what you pay for’ also applies to some extent to car insurance. I still shop around each year to see how my current insurer’s renewal invitation premium compares to other insurers’ prices, but I wouldn’t necessarily switch to the insurer quoting the cheapest premium.
