Can I renew my insurance on-line?

One for the insurance department maybe......

Our van is insured with the Club, I can see basic details of the policy in my profile.

We will be away abroad when the renewal is due in July, so can I do that on-line via this website?

As we have "new for old", the price of a new van increases each year, and we  have to work out a new insured amount. 

The Club helpfully tells us the new van price, but what we really need to know as well is, how much was it before, so we could just add the extra.  But on our policy it shows van and equipment as just one amount, and we can never remember how we arrived at the figure.

If I cannot renew on-line, can I arrange an automatic renewal and get the increase added automatically?
