Do Electric Cars Cost Less to Service — The Real Numbers

Understanding Electric Vehicle Servicing Costs

As electric vehicles (EVs) gain traction in the UK market, potential buyers often wonder about the long-term costs associated with owning one. A common question is whether electric cars cost less to service than their petrol or diesel counterparts. To answer this, we need to dissect the various components of servicing and maintenance, including parts, labour, and the overall frequency of required services.

The Basics of EV Servicing

Electric vehicles are fundamentally different from traditional combustion engine vehicles. They consist of fewer moving parts, which can lead to lower servicing costs. For instance, an electric car typically has no oil to change, no fuel filters, and fewer components that can wear out over time. This simplicity often translates to a lower frequency of servicing.

However, it’s essential to note that while the servicing costs may be lower, they are not non-existent. Electric cars still require regular checks on their battery systems, brakes, and tyres, among other components. According to a recent study, the average annual servicing cost for an electric vehicle in the UK is around £200-£300, compared to £300-£400 for petrol and diesel vehicles. This difference can be attributed to the reduced number of parts that require regular maintenance.

Battery Health and Maintenance

One of the most critical aspects of owning an electric vehicle is maintaining the battery. The battery is not only the most expensive component of an EV but also the one that requires the most attention. Battery health can significantly affect the overall performance and longevity of the vehicle.

Most manufacturers recommend checking the battery health every 12 months, which can involve diagnostic checks to ensure the battery is functioning optimally. Depending on the make and model, this check can cost anywhere from £50 to £150. For instance, the used BMW i3 has a reputation for battery longevity, but regular checks can help maintain its efficiency.

In addition to battery health checks, owners should also be aware of the warranty coverage for the battery. Many manufacturers offer warranties that cover battery performance for eight years or 100,000 miles, which can provide peace of mind for potential buyers. However, if the battery does need replacement, costs can range from £3,000 to £7,000, depending on the model. This potential expense is crucial to consider when evaluating the overall cost of ownership.

Real-World Range vs Manufacturer Claims

Another factor that can influence servicing costs is the real-world range of electric vehicles. Many manufacturers advertise impressive range figures, but real-world conditions often yield different results. For example, the Nissan Leaf is marketed with a range of up to 239 miles, but in colder weather, this can drop significantly.

Understanding the actual range can help owners plan their charging and servicing schedules more effectively. If an EV frequently runs out of charge, it may lead to more frequent visits to charging stations, which can incur additional costs. Moreover, the need for rapid charging can put extra strain on the battery, potentially leading to earlier degradation and increased servicing needs.

Charging Costs and Infrastructure

Charging costs are another critical component of the overall cost of owning an electric vehicle. While electricity is generally cheaper than petrol or diesel, the costs can vary significantly based on where and how you charge your vehicle. Home charging is often the most economical option, with costs averaging around £0.14 per kWh. For example, if you have a vehicle with a 60 kWh battery, a full charge would cost approximately £8.40.

However, public charging stations can present a different scenario. Rapid charging points, often found at service stations, can charge significantly more per kWh, sometimes exceeding £0.30. This discrepancy can add up quickly, especially for those who rely on public charging due to lack of home charging facilities. Understanding these costs is essential for budgeting and can influence the overall servicing costs of an EV.

Common Problems Specific to EVs

While electric vehicles are generally reliable, they are not without their issues. Some common problems include:

• Battery Degradation: Over time, all batteries lose capacity. Monitoring battery health is crucial to ensure optimal performance.
• Software Updates: Many EVs require regular software updates, which can sometimes lead to issues if not performed correctly.
• Brake Wear: Although EVs use regenerative braking, which can extend brake life, they still require regular checks and maintenance.

These issues can lead to additional servicing costs. For instance, if an EV’s battery begins to degrade significantly, it may require more frequent checks and potential replacement, impacting the overall cost of ownership. Additionally, software issues can sometimes necessitate visits to the dealer, which can add to servicing costs.

Running Cost Savings vs Petrol/Diesel

When evaluating the overall cost of ownership, it’s essential to consider the running cost savings associated with electric vehicles. According to various studies, EVs can be significantly cheaper to run than traditional petrol or diesel vehicles. For example, the average cost of running an electric vehicle is estimated to be around £1.50 per 100 miles, compared to £6-£8 for petrol and diesel vehicles.

This difference in running costs can offset some of the initial purchase price of an electric vehicle. Additionally, electric vehicles are often exempt from road tax, which can further enhance savings. The GOV.UK road tax website provides detailed information on tax exemptions for electric vehicles, making it easier for potential buyers to understand the financial benefits.

Furthermore, many local councils offer incentives for electric vehicle owners, such as free parking or reduced congestion charges, which can further enhance the cost savings associated with EV ownership.

Dave's Verdict — Is It Worth Going Electric?

After analysing the various aspects of servicing costs for electric vehicles, it’s clear that they offer several advantages over traditional petrol and diesel vehicles. The lower servicing costs, combined with reduced running costs and potential tax savings, make electric vehicles an attractive option for many buyers.

However, potential buyers should remain aware of the potential pitfalls, such as battery replacement costs and the need for regular battery health checks. Understanding the real-world implications of owning an electric vehicle can help buyers make informed decisions. For those considering an electric vehicle, it’s advisable to check the specific model’s history and servicing records. Tools like the free vehicle intelligence report can provide valuable insights into the car’s past, helping buyers avoid potential pitfalls.

In conclusion, while electric vehicles may have a higher upfront cost, the long-term savings on servicing and running costs can make them a financially sound choice. As the market continues to evolve, the benefits of going electric are likely to become even more pronounced, making it an option worth considering for any car buyer in the UK.
