A Warrant of Fitness (WoF) is your vehicle’s legally required safety stamp - it checks the key systems that keep you, your passengers, and other road users safe. It’s not a full health check, though, so for engine and mechanical reliability, consider a pre‑purchase or full service inspection, especially if you're buying a used car. Here's what you need to know:

​

How often?

• Vehicles first registered on or after 1 January 2000: Initial WoF at first registration, then at three years, and thereafter annually

• Vehicles registered before 1 January 2000: Must be checked every six months 

 

What’s inspected?

Inspections focus on critical safety features only. They include:

• Tyres – tread depth and overall condition

• Brakes – performance and braking efficiency

• Steering & suspension – alignment, wear, and mechanical function

• Lights – all lights must be operational

• Glazing & wipers – windscreen condition and washer/wiper operation

• Seat belts & airbags – integrity and correct function

• Doors – must open and close safely

• Speedometer – must work accurately

• Exhaust & fuel system – no leaks and within noise/ emission limits

• Structural integrity – no unsafe rust etc. 

• Not inspected: engine performance, fluid levels, gearbox, clutch, differential, paint, or non-structural elements .
