Components inspected during a Single Vehicle Approval

Most of the items inspected in the Single Vehicle Approval (SVA) scheme are the same as those that are tested when manufacturers apply for type-approval of mass-produced vehicles. Find out below what components are examined during an SVA inspection.

Components inspected

The following table lists the items inspected for the two levels of SVA for light goods ‘Special Purpose’ vehicles. All of the items for Standard SVA are checked at the Vehicle and Operator Services Agency (VOSA) test station. However, items for Enhanced SVA (ESVA) cannot be checked at the test station. You will need to provide documentary evidence for such items to show compliance as explained below.
