Anyone got any examples of an insurance company not paying out because someone had a water tank?
Specific examples, no but I have had plenty of in depth conversations with a number of insurance companies over the past decade, specifically for the purpose of insuring a water tank. Skip to the last paragraph if you'd like to avoid the waffle.
The primary response from most of the companies, at least initially, was simply down to how they understood the term 'modifcation'.
Some companies viewed that as ANYTHING the vehicle didn't have when it left the factory - non standard audio, seats, trim, racking, tanks, wheels, tyre sizes etc.
One company wouldn't allow me a bolted down tank as it was a 'modifcation and may affect the integrity and safety of the vehicle'.
My response was that I'd just chuck it in the back, to which they designated it an 'unsecured load.' and wouldn't cover that either.
I asked if a wheelbarrow needed to be secured and they said no as that was 'cargo' and could be removed.
I then pointed out that a water tank could easily be removed and, like a wheelbarrow, was therefore 'cargo' too.
We went around in circles for a bit until I realised it was pointless and moved on.
The conclusion was: Each insurance company uses a different set of parameters for determining risk.
SOME will not insure AYTHING added to the vehicle without in depth breakdown / premium loading and much arguing.
OTHERS simply do not care what you do within the confines of what is legal - like my current insurers who are quite happy with my unsecured tank and my frequent off road activity.
If you have an insurance company that quibbles over anything and you had any modifications that you hadn't declared and were then involved in an expensive accident they will simply pay out for the 3rd party damage and then sue you personally for the loses they've incurred. If it runs into hundreds of thousands of £ then they'll simply take your assets to recoup.
This also occurs with modified cars and some policies with a drink drive exclusion where the driver was over the limit.
