How to Prepare for an Inspection

Ensure lights are in good working order. Check indicators, brake lights, headlights (dipped and high beam), and park lights.
Check tyre pressure and tread. Correctly inflated tyres are more fuel-efficient and provide better road grip. Before inflating, make sure to check the recommended tyre pressures for your car.
Check your car oil level with the dipstick to make sure it reaches the indicator mark.
Ensure all seatbelts are accessible, functioning, and in good quality before the inspection.
Ensure that your window wipers are clean and working well. Also, check that your windscreen washers deliver clean water smoothly only the windscreen.
Make sure your car boot is empty before your vehicle’s inspection. This makes it easier for us to check your spare wheel and complete the inspection faster.

Note: If you do find any issues during your pre-inspection check (blown bulbs, insufficient oil level), we can help with that! For the small stuff, we can sort that out for you during your assessment. For other issues, feel free to contact us for a service and repair.

Vehicles first registered 2000 or later - Annually
Vehicles more than 2 years old but less than 3 years old - Annually
Vehicles less than 2 years old - WoF is issued until the vehicle’s third anniversary from when it was first registered.
