We receive many calls regarding  the old SVA, now IVA and registration, especially in relation to 'older' incomplete projects.  The rules are actually easy to follow but are not always followed by the relevant authorities which makes giving an exact answer very difficult.

As a general rule, a kit that was built on a Herald chassis SHOULD NOT require an IVA and therefore, in theory, can be built and then DVLA notified that the car has had a body change.  Occasionally DVLA don't agree with themselves on this one and try to insist that it will require an IVA.  If an older type kit is submitted for a test it will fail as there are quite a few significant changes that are required and several smaller not so significant changes that are required in order to pass.

By rights a kit built as above should just be inspected by DVLA to ensure that the engine and chassis numbers match the V5. The V5 is then amended to reflect the changes to the body style.


We are often asked about what type of chassis is what.  The simplest way of identifying it is to get under and have a look.  If the chassis curves in from the two main rails somewhere near the middle of the car then it is likely to be a Triumph.  They had a 'waist' around the back of the gearbox area and it is this 'waist' that gives it the curved shape.  The Gentry chassis is almost two straight rails.  Slightly narrower at the front than the rear and is likely to be made from 4" x 2" steel box section.

If the 'part built project' or '90% complete, only needs a few weekends to finish' kit has been built on a TP motors chassis which is used as a replacement for the donor cars chassis then the car will require an IVA and unless some changes are made it is unlikely to pass.

Now there are occasions when these types of kit have 'slipped' through the net and have just received an identification check, so yes I know that occasionally such a result is possible, but, no-one can guarantee it.  This means that if you listen to the wise knowledgeable kit builder and he encourages you to go for it, 'because everyone else is telling you a load of twaddle' then you may find yourself spending more money than you wanted to and investing a lot of time into a project that will never be used on the road.

The choice is yours.  We are only offering to provide some clear information on the possibilities!

If you are unsure about what your intended project is then give us a call or email us some details and we'll give you our opinion on what you could be letting yourself in for. Advice costs nothing, but may save you unnecessary expenditure of both time and effort.



The Registration process of your newly built Gentry kit is quite clear and easy.  The build manual contains copies of the relevant forms with details of how to complete them, if you get lost or confused we are here to help you.

DVLA will wish to inspect the vehicle to ensure that all the numbers match.  Once completed they will issue the car a new number.  This will be age related to the donor but is unlikely to be the donors number.  At this point your car will be registered as being built in the year in which it is examined and is considered to be a 'new' car.

The IVA pass certificate entitles you to 3 years before an MOT is required, but regardless of what donor you used, you will lose your 'historic' classification.  The 'age' related plate is simply a means to register the vehicle and to decide on emission requirements at later MOT tests.

We will provide assistance in this process to those who have purchased a kit.
