If you run an MOT site or you’re an MOT Tester yourself, Quality Control (QC) checks are something you’ll hear mentioned regularly. But in practice, QC is one of the areas we see misunderstood, overlooked, or incorrectly applied far too often.
At Pro-Tech MOT & Automotive Academy, we support MOT stations every day with compliance, site reviews and disciplinary cases. One thing is consistent: robust, well-documented QC checks protect testers, protect the Vehicle Testing Station (VTS), and significantly reduce DVSA risk.
So let’s clear up what QC checks really involve, how often they’re expected, and how to make sure yours stands up to scrutiny.
What Are QC Checks?
A Quality Control check is an independent review of an MOT test carried out by an authorised tester. It provides a second set of eyes to confirm that the inspection was completed correctly and in line with DVSA standards.
Done properly, QC checks:
- Identify errors or training needs before DVSA do
- Promote consistency and fairness in test outcomes
- Provide documented evidence of compliance
- Reduce the likelihood of disciplinary action or adverse site review outcomes
QC isn’t about catching people out, it’s about maintaining standards and protecting everyone involved.
How Often Should QC Checks Be Done?
This is where we hear the most myths and where DVSA expectations are often misunderstood.
“I’m testing on my own, so I don’t need QC checks.”
This is incorrect.
DVSA expects all testers to receive QC checks – including lone testers.
As a minimum expectation:
- One QC check every two months
- Based on an average of 2-3 tests per day
- Increased pro-rata if a tester is carrying out more tests than the national average
For lone testers, DVSA still expects some form of QC process, which may include:
- Regular, documented reviews of TQI data
- Independent oversight where possible
- Clear records showing checks are being carried out and reviewed
In all cases, QC activity must be documented.
“I’m the manager and I do the QC, so I don’t need a QC check.”
Again – incorrect.
The QC role has been removed from MTS, and DVSA now expects ALL testers to receive regular QC checks regardless of their role within the VTS.
Being the following does not remove the requirement for QC oversight.:
- The manager
- The AE
- The AEDM
Every tester must be subject to regular, independent quality monitoring.
What Should a Proper QC Check Include?
A meaningful QC check should involve more than ticking a box. At a minimum, it should include:
- Observation of a full MOT test or structured review of CCTV footage
- Confirmation that the Inspection Manual and Testing Guide were applied correctly
- A review of the outcome to ensure it aligns with DVSA standards
- Constructive feedback for the tester
- Clear, auditable documentation of findings and actions taken
QC checks should result in learning, improvement and protection – not paperwork for paperwork’s sake.
Common QC Mistakes We See
Through our work supporting MOT stations nationally, we regularly see issues such as:
- QC checks not being done at all
- Checks carried out informally with no documentation
- The same person “marking their own homework”
- Repeated errors not being addressed
- Assumptions that “no news is good news”
DVSA will review your QC process during site visits. If it’s weak, inconsistent or undocumented, it can quickly escalate into Improvement Needed outcomes, warnings or disciplinary action.
Best Practice Tips from Pro-Tech
Based on DVSA expectations and real-world experience:
- Schedule QC checks as a routine activity, not a reaction
- Use a standardised QC form for consistency
- Increase frequency for new, returning or higher-volume testers
- Use QC outcomes to guide CPD and refresher training
- Keep QC records for at least five years
- If independence isn’t possible in-house – bring in external support
