Why Regular Car Servicing Matters

Your car is one of your most important (and expensive) assets. Routine servicing helps:

  • Catch problems before they become costly
  • Maintain fuel efficiency
  • Keep your warranty valid
  • Preserve resale value
  • Pass your MOT with fewer issues

Still, one of the most common questions drivers ask is: how often should I service my car?

Recommended Car Service Intervals (UK)

Most modern cars should follow one of these general rules:

  • Every 12 months or 12,000 miles — whichever comes first
  • Or follow your manufacturer’s recommendations in the handbook
  • Some newer cars have onboard diagnostics that alert you when servicing is due

If you drive more frequently or in harsh conditions (like short city trips, towing, or dusty environments), more frequent servicing may be needed.

Interim vs Full vs Major Service: What’s the Difference?

🧰 Interim Service

  • Every 6 months or 6,000 miles
  • Basic checks: oil change, fluid top-ups, brakes, tyres
  • Great for high-mileage drivers

🛠 Full Service

  • Every 12 months or 12,000 miles
  • Includes 70+ checks
  • Air filter, brakes, suspension, steering, and more

🔧 Major Service

  • Every 2 years or 24,000 miles
  • Includes everything in a full service + spark plugs, brake fluid, cabin filter

How Long Does a Car Service Take?

  • Interim service: 45 minutes to 1 hour
  • Full service: 1.5 to 2.5 hours
  • Major service: 2 to 4 hours

Some services may take longer if extra repairs or diagnostics are needed. Many garages offer same-day turnaround, and mobile mechanics may even come to your home or workplace.

What Happens If You Skip Servicing?

Delaying or skipping your service may:

  • Invalidate your warranty
  • Cause bigger repair bills down the line
  • Reduce fuel efficiency
  • Increase the risk of breakdowns
  • Lower your car’s resale value

🔧 Preventive maintenance is almost always cheaper than repairs caused by neglect.
