Understanding Vehicle Services: Interim, Full & Major Explained

What Is Vehicle Servicing?

Vehicle servicing is routine maintenance designed to keep your car running safely and efficiently. We schedule different types of services “Interim, Full, and Major ”  based on mileage or time intervals to detect and fix issues before they cause breakdowns

Why Is It Important?

Regular servicing preserves engine health, improves fuel economy, maintains safety, and protects your manufacturer warranty. The Society of Motor Manufacturers and Traders (SMMT) confirms that serviced vehicles have better reliability and higher resale values.

According to the UK Department for Transport (DfT), around 16% of road accidents in the UK are attributed to mechanical faults, many of which regular servicing could prevent. Neglecting essential maintenance significantly increases the risk of vehicle breakdowns or failures on the road.
