doesnt matter, they will still insure him on the van witout wfp, and that is what the policy waas originaly, thats what they will claim, had they insured him with wfp then said no after taking some money, they cancel with out penalty, he can cancel it now and pay a penalty, but that depends on how longs left,
have you checked that they will insure you on a new van with wfp, as they might just be saying that to sod you off, as usually they are happy to take you money and then say get lost when you try and claim
