It's not about how the tank is fixed apparently. It's the carriage of the load. It baffles me. My tank at the mo is strapped with two 5 t straps to vans anchor points. But if your a builder you could place a pallet of bricks in the back and everything is OK. To me it just seems like they are jumping on the band wagon to get extra cash out of us.
When I first started no one ever asked about tanks, now they treat you like a criminal if you have one.
Always worth a try and will give direct line a call tomorrow.
Well don't mention it then. You're just handing them a reason to bump the price. You're carrying a load using the manufacturers anchor points & you are carrying weight below the manufacturers stated payload. Your load is not explosive, corrosive or a health hazard. THEY DON'T NEED TO KNOW! You're a tradesman carrying a load to carry out your work.
I bet when builders ring up they don't stand there telling them what they are carrying around in the back every day! Or joiners, or plumbers, or landscape gardeners etc etc.
Taking the above into consideration (you're doing nowt wrong or untoward) what would their defence be in the event they refuse to pay out after an accident- "we're not paying 'cos you were carrying something heavy"!!

You'd be fully insured now & for a lot less money if you weren't influenced by over cautious twerps on here!! 
im sorry but this is rubbish advise, if you had a seriuos accient like a 5 car pile up on the moterway and a investiagtion time were involved you would find your insurance void.
my mum works for a insurance company and has told me of two incidents were this has happened.
is it fair a window cleaner is treated different for carrying water than a bricie for carrying bricks.....NO but the trruth is they class it hs a mod if not declared you may end up fooked........but then again you m at never have aseriuos accident.......thats the risk you take
I've followed the manufacturers recommendations Ronnie, have you? Does the manufacturer of your van recommend drilling holes through the floor/chassis or clamping plates around the main chassis members?
Who, apart from Ionics can back up their system fittings with official engineering tests/reports?
You might just find that YOUR insurance be void in the event of a serious accident once an engineers report has been given & the manufacturer has their input also!
Personal safety is our own choice but don't think for one minute that you are absolved of any responsibility whatsoever just because you have a caged tank! Have you compromised the manufacturers designed structure by your actions?
Food for thought.
