I think they can make their own T&Cs as the clause is nto an unfair clause and if the caravan is manufactuered with a MTPLM which is at a fixed value surely they do not have to prove whether the 95% was exceeded or not as they can use the value on the sticker?
It would probably be up to the consumer to prove that caravan did not exceed 95% of the car's kerbweight. Car insurance only pays for third party claims and not for th caravan that may have been damaged, but we all know that anyway? Best is to be careful.
Becasue this policy is for CARAVAN insurance not CAR insurance, I agree they can probably write their own T&C's. There are probably no regulations that specific set out how caravan insurance policies should be offered beyond regulations that cover general insurance.
But the policy would need to come under unfair contracts and as such policy T&C's do need to be fair and workable.
The way the cause is written is specifically says
" if Your Caravan weighs in excess of 95% of the towing vehicle’s kerb weight." There are two criteria it relies on - The weight of the towed caravan and the kerbweight of the tow vehicle.
You cannot know the weight of an object unless it is measured.
How many times have wee seen caravanners struggling to find their cars kerbweight. Some can't be found, and often when they have checked them on a weigh bridge how different the measured value is compared to the ex works value becasue of things like the addition of standard equipment and things like towbars etc,
Basically the clause is unworkable as neither of the criteria they specify can be determined easily or accurately.
If the insurance company tried to use the clause to reduce or stop a payout and they based their calculation on the MTPLM of a manufacturers kerbweight figure, the policy holder could legitimately argue that the criteria are not set out in the policy.
