Yes, providing a customer viewing area is a DVSA requirement for all authorised MOT test sites. Customers have the right to watch their vehicle being tested if they choose to, and your site must include a designated area that allows them to do so safely. This can be a clearly marked physical area separated from the working zone of the test bay, or viewing via a screen, often in the comfort of the customer lounge or reception area. Either way, the facility must be free from obstructions and genuinely accessible.
Keeping this area in good order is just as important as having it in place. Workshop clutter can easily encroach on a physical viewing space over time, so it is worth checking regularly that floor markings are still visible and the area remains accessible. If you use a screen, make sure it is working correctly and positioned where customers can easily see it. A well-maintained viewing facility signals to both customers and inspectors that your station operates transparently and to the required standard.
