Have a procedure and keep good records to reassure the DVSA that you are doing Quality Control (QC) checks correctly. Use the second page of the VT29 document, this has all the details of the MOT tester and who the tester is printed at the top of the page. There is a large blank space for the Quality Controller to add their comments/observations of the test/tester. Both parties should sign this document that they agree on the written notes. Keep these documents for 12 months. Having detailed notes rather than “good test” or similar will go a long way to reassuring DVSA that you are diligently carrying out your mandatory QC checks.
