NFU suck when it comes to claims, i am with Peter Best (insurance is norwich union though) and i cant fault them.
I've made 3 claims through NFU, and they're very quick at paying out in my experience, but not as good as getting the money back from the other insurance company (took 18 months on the 1st claim, and still waiting on the second one nearly 2 years after the event!).
The Octavia's with Flux, but they want silly amounts for the renewal, and have refused to protect my no claims as I now have 3 claims (1 not at fault, 1 pending and 1 at fault) in the last 5 years. So, it's off to the dealers tomorrow to sell it...
Cheers
Ben
