ACE have attempted to clarify certain areas that go to the very root of a car's identity, and how much you are allowed to modify the chassis or monococque, before you lose the 5 points it represents.


We have been liasing with both DVLA and VOSA to clarify this area.
Initially we received this reply from DVLA:
"When assessing a modified/rebuilt vehicle, DVLA's main interest is to establish whether the original identity has been compromised by the changes made. If a vehicle has been modified from the original manufacturer's specification or if not enough of the original components have been retained in the build, the vehicle identity will change and IVA will be required to register with an alternative registration number.
Due to the very nature of rebuilding or modifying vehicles from their original manufacturer's specification, DVLA assesses each vehicle on its own merits based on the documentary evidence provided and a physical inspection of the vehicle.

The INF 26 information leaflet, and the information given on the website, is issued as a guideline to the registration of rebuilt, radically altered or kit converted vehicles. They are not meant as technical guides. However, both clearly indicate that if modifications are made to the chassis or monocoque bodyshell, or if the build does not include enough original, major components (as listed) the identity of the vehicle will change.
The information on www.direct.gov.uk is regularly reviewed to reflect changes in legislation

VOSA have provided the following response to your questions;

Monococque.

Q) What is the definition of a monococque ?

A) A design in which body and chassis are all one unit.

Q) Why does cutting into a monococque affect the vehicle identity if it retains the same shape /profile as before.

A) Cutting is considered to be modifying the vehicle from its original specification. Any modification to the chassis/monocoque body is considered to render the vehicle no longer original specification or of original identity.
