Car Servicing Guide: How Often and What's Included in the UK

Summary

• Service your car every 12 months or 12,000 miles: Whichever comes first. Some manufacturers specify different intervals.
• Interim, full, and major services cover different things: From basic oil changes to comprehensive inspections.

How Often Should You Service Your Car?

Most manufacturers recommend:

• Every 12 months or 12,000 miles (whichever comes first) for a full service
• Every 6 months or 6,000 miles for an interim service if you drive a lot
• Every 2 years for a major service

Check your owner's manual for the manufacturer's specific recommendations. Some modern cars have variable service intervals based on how you drive — the car tells you when it's due.

Main Dealer vs Independent Garage

You do NOT have to use a main dealer for servicing. Under the Block Exemption Regulation, any qualified garage can service your car without voiding the manufacturer warranty, provided they:

• Use parts that meet the manufacturer's specifications (not necessarily branded parts)
• Follow the manufacturer's service schedule
• Stamp the service book or provide proper documentation

Independent garages are typically 30-50% cheaper than main dealers for the same work.

Service vs MOT: What's the Difference?

• MOT: A legal safety inspection required annually for cars over 3 years old. It checks whether the car meets minimum safety and environmental standards
• Service: Preventive maintenance to keep the car running well. It's not legally required but is essential for reliability and value

An MOT is not a service, and a service is not an MOT. You need both.

Why Regular Servicing Matters

• Reliability: Regular oil changes and inspections prevent breakdowns
• Safety: Catches worn brakes, tyres, and steering issues early
• Value retention: A full service history adds hundreds to your car's resale value
• Warranty protection: Missed services can void your warranty
• Fuel efficiency: A well-maintained engine uses less fuel
