Down Rating

Postby ralph » Sat Mar 14, 2020 4:21 am

I have decided that I want to run single rear wheels on my S75 which means that it will need to be down rated from 7.5t to 6.6t has anyone been though this process before.
I assume that a new plate / certificate will be issued after down rating which would also solve my problem of not having a certificate for it at all.

Hiya Ralph, when I bought my van (4.5tonne Renault Master) it came with all the neccecary paperwork and new chassis plate to down rate which the previous owners had paid for but never sent of to the DVLA.
As of yet I haven't done anything with it. The down rating was carried out by SV Tech, link added below.
I think Brian and one or two others may have done this themselves?

I did downrate my truck, but eventually put it back up again..... I used SvTech to downrate it originally as you had to fit metal plates between the axle bump stops to reduce the movement!!!! but I uprated it again myself some years later, using form VTG3 iirc.... no need for the expense of SvTech.

Obviously this was for my Leyland DAF T244 which is a 10.8t truck, but assume it is the same for a van.....

Downrate procedures depend on the current reg status / body class.

The downrate may be possible by a 'simple' approach to DVLA with supporting docs and proof you've had a new plate made - or you might have to go via DVSA making an application on form VTG 10 to have a new Design Weight Certificate issued, which you can then use to support the downrate application to DVLA.

There's not much to be lost (apart from time and frustration) trying the first option.

The latter is what Brian had to do to uprate back to 10.5T or so.

SvTech are the easiest option. They have access to the data (usually) and documents that will be required if there are problems and have working protocols with DVLA / DVSA.

Thanks for the replies I under stand that no mechanical changes are necessary and I only have to down rate because of the change in the load bearing capacity of the single rear wheels as opposed to twin rear wheels.
I just need to find the supporting documents get a new plate made and then have it approved. Given my luck with DVLA I can foresee all kinds of problems :(

Chances are SVTech will have all you need on file. You'd have to check current pricing but if it's still £100 or so for this service it's probably worth it to avoid the potential grief. If you approach them, you could even ask if they could help nudge your motorcaravan application along. I have no idea if they could help but I do know they have direct lines into DVLA.

The few times that I've spoken with SVTech I've found them to be very helpful.

SVTech are indeed a decent company, I have dealt with them and had absolutely no issues with them.

I have also never heard of anyone having a problem with them. I also think their prices seemed, at the time, to be decent as well.

My son reminded me that we found the plating certificate when we stripped the original cab......its already been down rated to 6.00t
But thanks for all the helpful advice.
My concern now is that the tyres I have are not load rated high enough, even with the reduced GVW, for single wheels on the rear and I may have to find a couple more wheels and run twin wheels on the rear or find some different tyres with higher load rating or maybe get some super singles made.
