I remember getting my local garage to bolt the tank frame to the floor which they did with spreader plates on my old Ford Connect. TCW fits for free if you have a system off them but as I'm looking for a flat lay tank this time around I'm going to have to look elsewhere because they only sell upright versions.
I was led to believe that if your tank wasn't professionally fitted then your insurance would be void. I've just renewed my insurance with Howden who I've been with for a while at a cost of only £360. Very cheap I thought.
I always declare my tank is DiY bolted through the floor. Never had a problem with insurance.
No issues paying out after my significant prang of 2023.
No problem getting insurance afterwards.
Some insurance companies ask who fitted the system , some want a written certificate stating it’s professionally fitted , others don’t ask for anything
No 💩

It’s the water sloshing that is a pain.
upright tank is the answer

« Last post by colin bird on January 07, 2026, 08:16:16 pm »I used to change my van every four years so would sell them with system fitted,I factored in the sale price of the van the price to ncude the system I always got a good price for van and system as the van was low mileage.I’ve had four pure freedom 40 inch ro van mounted systems over 17 years never had any problems ,but I think there more expensive now than they used to be due to the business take over a couple of years ago
Ive found its better for me to just get one system fitted into a new van and keep it well maintained for 10-15 years before getting a new van and system.
I only use my van for work though. If it was my only vehicle I'd be changing it more frequently most probably.
My current van is six years old in march with same system since new,this sadly will be my last van as I’m 67 in a couple of years will then go very part time if health allows until I’m 70 and will subsidise my income with my pension. And government pensionim not looking forward to retiring as I feel work is good for you in many ways

Should have read van is 15 years old I've owned for 11 years.Professional fit every time esp if you want a diesel hot system. Get it fitted into a brand new van if you plan on window cleaning for many years to come.I've had this van 16 years Daz but as I'm scaling down to doing less as I'm now only part time so for a start I don't need a 500 litre system a 350 will be fine I also want a nicer more up to date van etc which I'm hoping when I retire fully in around 3 years time I'll be able to sell for a decent price.
Nothing worse than messing about every few years switching systems from van to van.
16yrs,thats impressive, what van have you got?

Unless there is something seriously wrong with your van it should last 3 more years of part time work
