My van that I asked for a quotation for was for a 2013 Fiat Scudo 2.0JTD with 80,000 miles. I explained it that I had heard there were issues with DiY systems and insurance.

They informed me that they were no longer insuring vans with non-crash tested professionally fitted systems above 500Litres. (He mentioned Ionics of course
but also Purefreedom, Grippatank and WCW - I didn't ask whether those firms tanks were all crash tested) They also wanted me to describe how the system would be installed. (I replied with a frame bolted through the floor with plates underneath and 5 tonne lorry loading straps to the frame with the leading edge of the tank against the factory fitted bulkhead)
The gent I was talking to referred to one of the directors who he reported wanted to know if the tank was baffled. I replied it would be a 500L tank Wyedale (

The chap said that was ok and gave me a quotation. He reiterated that 500L was the maximum tank size.
HOWDEN'S/A-Plan
No problems getting a quote up to 1000litres if it was 'properly secured'. I asked what that meant and was told that I should describe how it was secured which I did. They did say that more of their insurers preferred 500L or 650 as a maximum and that the bigger the tank the more limited the choice of insurer is.
I asked A Plan and AS if they had heard of claims from tanks being inadequately secured and they both said they had heard of one up in the north east but that their company had not brokered the insurance.
AS said they were trying to weed out people putting something like 1000L IBC's in the back of their vans.
A sidenote. Dan the Man was involved in a no fault claim last year which meant he had an Ionics van supplied while he was off the road. He wasn't impressed. He said the system leaked and he had to provide a battery - for which he was reimbursed - for some reason to 'make it work'.
I asked how it was secured and he said it was in a cage which was bolted through the floor but he didn't look underneath. Strangely to my way of thinking the tank wasn't against the bulkhead. (Maybe the strongest points of the floor meant the tank frame couldn't be put against the bulkhead - I don't know?)
