Question: Rtention of No-Claims Bonus?

Hi, My wife and I are in the same boat in that we are both due to retire later on this year. Like you, we have two cars and a VW camper which we purchased just over two years ago as a works van. I took a year to convert it and the insurance cover had to be very specific during that time. After the conversion and subsequent reclassification by DVLA to a Motor Caravan, we had to start shopping around for insurance as the premium went up instead of down as we had be assured by the first broker.
One year further on the premium only went up by a few pounds but we shopped around again and have managed to secure quite a good deal through the Caravan and Camping Club with a decent annual mileage allowance and generous Euro-cover at a saving of £60.00. The second broker that we dealt with said that we didn't have any no-claims bonus to transfer on as it was a camper policy but I reminded him that my first broker had given me one years NCB. He then changed his mind and admitted that I was in fact due two years NCB and then kindly provided me with a letter of proof for my new insurer.
I mentioned the topic of retirement to one of the brokers and he said that my camper van premium would probably go down because of that. I wonder if any other owners have experienced that this is in fact the case?
We are also thinking about ditching one of the cars when we retire and your tip about alternating the insurance cover every year is worth considering. Thanks for that..........

Regards,

Do you mind me asking, Alan, whether you insure both people on your insurance or just one? And, if two, does this make any difference to the cost of insurance? We are finding that it is cheaper to have only one named driver, but this makes sharing the driving in our 'van difficult, plus we both need the practice!
