This list provides details of authorised designated tehnical service providers for IVA testing. You’ll need to use this list if you’ve to pay for your own IVA tests to be carried out.
Another way to prove your vehicle is compliant is to use an IVA model report, which shows that your vehicle is the same specification as another.
If a model report has already been produced for a vehicle, you may be able to use it for a fee. Details of current reports can be found in the Driver and Vehicle Standards Agency list of ‘Model reports and their owners’.
