I put in a bid for a load on CX the other day, and was told that I would need to take out GIT of £400,000 for the day, and the cost would be passed on to the customer. I asked my insurance provider, who said they'd never heard anything like it, but passed on the request to Aviva, the underwriters. Aviva replied that that level of cover would cost thousands, far more than I'd earn, and there would have to be special security arrangements in place, such as the van being guarded 24 hours. So basically, they wouldn't do it for me.
The work was being subcontracted to vans across the country, so presumably other people managed to get this level of cover.
Does anyone know how it's done?
