Quick question (hopefully!).

I am currently looking for a kit car. Is there anyway to do an online check to see if the car has passed SVA/IVA? I know I can ask the owner but it's a ball ache and was hoping something might be available online.

I've had a quick google without success but sods law I missed it.

I know this is possible for insurance, MOT, V5 etc.

Thanks.

The answer is no.

I built a kit car and had SVA tested. I registered it as a new car.

This is the current info from the DVLA website.


I do not now own the car BTW.

Year of manufacture should let you know, right? If it's manufactured after the introduction of sva or iva, it must have passed those tests in order to be registered.

In the cross over period around SVA introduction there is no easy way to know if a car took the test or not.

For anything since, it simply won't get the correct registration document without it. I cant imagine you'd get away with trying to pass a kit car off as a body conversion on an existing vehicle either.

The MAC (Ministers Approval Certificate) which is the 'proof' is handed over to get it registered (I kept a copy of mine :-) ). If it was built pre-SVA (and indeed for anything since) the main thing is that it's correctly registered. If it's on a Q reg then the odds are that it is correctly registered (someone correct me?) Certainly if the make/ model is something like GTM or whatever (IF that is what it resembles) rather than Austin, Jaguar etc, then again it would appear ok.
There have been some small numbers of kitcars 'ringed' by using the ID of another eg A more recently-assembled 'Robin Hood' kitcar has it's identity on the V5 as a 'Dutton', so although what was once a Ford was correctly registered as a Dutton, it now may have a different chassis and be incorrect.
As with buying any car (including a mass produced) tread carefully!

A "Q" reg simply means that it has been re-reg in some way at some time & DVLA weren't happy they could give an age related plate, no guarantee it has had any form of test or indeed is even the car it says it is - take your example above of the Robin Hood/Dutton

A different question relating to SVA/IVA.

I have an early MkII Midas sitting in my garage which in intend to make a major change to the engine/gearbox, hopefully retaining (upgrading) the front suspension and brakes. The change is to replace the 1275 engine and transmission with a Bosch eAxle. The eAxle is a combined electric motor, transmission and controller and looks to be about the same size as a mini gearbox. 150kw eAxle weighs about 90kg and searching on-line, the 1275 engine and gearbox weighs at least 150kg with power up to about 60kw (Metro turbo is about 70kw but is heavier still). Specifying the batteries and charging comes later.

Will I need to do a full retest when completed?

Thanks for all the input. As it happened the sale feel through anyway but I've learnt a bit. Thanks

I've no idea about the answer to this but this sounds like an interesting build. Build thread????

Electric conversion stuff
This project has been bubbling quietly over the years so I'm not going to commit to a build tread, unless you want an update annually. Too many other jobs to complete for SWMBO. (hint: don't buy a neglected Victorian farm house with half an acre)

Hmm - does a conversion to EV require an IVA test?

I can't begin to imagine why it would any more than going from petrol to diesel.

No vacuum for brake servo (unless vacuum pump fitted) Change of weight distribution affect handling/braking capability. Security/safety of cables carrying dangerously high voltage/power. Plenty more I haven't though of, I'm sure.

  • No servo in my Midas.
  • Power unit much lighter so batteries can be positioned to balance weight distribution.
  • There is a "tunnel between seats for gear linkage and handbrake which is ideally suited for big thick wires.
  • I can get rid of the tank holding volatile fluid at the back of the car.

I would be interested to see some pics. The Bosch axle does look good. Do you buy them new or is there a second hand market for them yet? What batteries are you planning to use? EV power in a small light kit sounds ideal. Start a thread! I don't care if it's updated once in a blue moon 😀

Yes, but how do we know (without it being tested) that the above has been done?
When my car went through SVA they weighed both axles, took measurements/notes of where additional passengers would be etc and fed it all into their program which worked out COG, brake apportionment etc. Power unit much lighter - so will it be overbraked on front end if you've 'balanced the weight'? You may well secure your cables properly, but someone else may not - that is the reason for the test. Changing from Petrol to electric is (I would suggest) a major change!

If you are converting from petrol to electric then whether it's a kitcar or an existing tintop makes no odds, the rule is very simple - are you going to cut & weld/modify the existing frame/monocoque of the vehicle? Yes = IVA, no = no IVA necessary

The fact that the driveline replacement might affect anything from CoG to brake balance or efficiency etc etc is irrelevant under the existing rules, it's no different to sticking a different engine/gearbox in,, as long as you don't cut the frame etc then no IVA required

Crikey - I have to say that is a surprise. Isn't there a caveat in the regs saying "major change" or similar, and if in any doubt you have to ask? I'm further surprised, as they seem to want 'mechanics report' or similar for an engine change, so I'd have thought a whole drivetrain change to electric would want some sort of verification, simply because it would reduce the VED to nil.

Well, I'm perfectly prepared to be corrected, but those are the current regs as I understand them - the only "major change" rule is chassis related, NOT engine/gearbox. Bear in mind that it may be quite difficult to actually fit a complete electric drivetrain & batteries WITHOUT cutting or welding the chassis (when it would become "radically altered" & require IVA). The other thing I find very strange is that, again TTBOMK, you can't build an EV from scratch like a kitcar unless it's below a certain voltage (I think it's around 48V, but can't remember for certain) which would make it almost impossible to build anything with decent performance or range. However, if converting an existing vehicle then there are no such limitations so far as I'm aware, so you can fry yourself & your passengers with 600V if it so takes your fancy!
