Plan a DVSA-compliant safety inspection (PMI) schedule in seconds — generate inspection dates with ISO week numbers from your inspection frequency, with red/amber/green status, mileage and defect logging.
Your safety inspection (PMI) frequency is set by the age, mileage and type of use of each vehicle or trailer — and the interval you commit to is stated on your Operator Licence. A planned, gap-free inspection schedule is a core part of your maintenance system and one of the first things a DVSA examiner checks. Drifting intervals are one of the most common findings at audit and at Public Inquiry.
SIPCAT takes your analysis start date and inspection frequency in days and builds the schedule for you — calculating each next-due date and showing the ISO week number beside it so it slots straight into a workshop plan. As you record actual inspection dates it shows the days between inspections with a clear red / amber / green status, plus mileage covered and defect logging.
Enter your details and inspection frequency, then add an inspection row each time one is carried out. Set the analysis start date and frequency first — the schedule, week numbers and RAG status update automatically.
| Inspection Due | Actual Inspection Date | Next Due | Days Between ⓘCalculated days/weeks between this and the previous 'Actual Inspection Date'. RAG status is based on the set frequency. |
VOR | Last Mileage | Current Mileage | Total Mileage | SI Fully Compliant | Dangerous Defects | Driver Defects | Related Defect Report | Brake Test ⓘRecord the type of brake performance test carried out during the safety inspection. |
