In February 2016, I called National Windscreens to replace my windscreen. They checked my insurance details and confirmed that they could do the work. The work was carried out five days later and the engineer who attended asked for my insurance details again. He also asked for me to pay the excess, which I did. Two weeks later, I received an invoice for the full cost of the windscreen (£370 minus the excess). I called the company and spoke to their accounts department. I stated that I never would have authorised NW to carry out the work if I knew they were not an approved supplier to Zenith Insurance. I wrote to them stating I was happy to go to small claims court to argue my case. I heard nothing more from NW until last week, nearly two years later, confirming they were taking me to court to pursue the debt. NW have confirmed that their Terms and Conditions allow them to pursue the payment from me in the event that the insurer won't pay them. I argue that having checked my insurance details twice, they should not have taken the work on knowing they were not approved by my insurer.
