Can you insure websites?

Hmmm I just noticed that my car (the Jaguar not the BMW) isn’t taxed at the moment as the tax expired at the end of September. The problem is that I need to show my car insurance to get my new tax disc. And my insurance doesn’t get renewed till next week. Bit silly really, but I think I’ll just wait till next week and tax it properly. I’m sure there’s an easier was to check if I have valid car insurance than having to dig up last year’s certificate (that’s assuming I still have it) I suppose
