EV Servicing: Is It Cheaper Than Petrol Cars?

Making the switch to an electric vehicle (EV) is an exciting prospect for many UK drivers, promising lower running costs and a reduced environmental footprint. However, a common question that often arises is: 'Do electric cars even need servicing?' And if so, 'How much does it cost?' The simple answer is yes, they do need servicing, and the good news is that it's generally more affordable than maintaining a traditional petrol or diesel car. Let's delve into the specifics of electric vehicle maintenance, helping you understand what to expect and ensuring your EV remains in peak condition for years to come.

As the automotive landscape rapidly electrifies, understanding the nuances of EV care is crucial. While the absence of an internal combustion engine (ICE) eliminates the need for oil changes and spark plug replacements, electric vehicles still comprise complex systems that require regular attention. From ensuring the optimal health of your battery to checking the wear on your tyres and the efficacy of your braking system, a comprehensive service regime is vital for safety, efficiency, and longevity.

Do Electric Cars Need Servicing?

Yes, absolutely. While electric cars boast fewer moving parts compared to their internal combustion engine counterparts, they are not maintenance-free. The misconception that EVs require no servicing often stems from the absence of traditional engine-related tasks like oil changes, spark plug replacements, and fuel filter changes. However, an electric vehicle is still a complex machine with critical components that require regular inspection and upkeep.

Think of it this way: an EV still has brakes, tyres, suspension, steering, and a sophisticated battery management system, all of which are subject to wear and tear. Regular servicing ensures these essential components are functioning correctly, preventing minor issues from escalating into costly repairs. It also helps to maintain the vehicle's efficiency, safety, and ultimately, its resale value. Neglecting servicing could lead to compromised performance, reduced range, and potentially invalidate your manufacturer's warranty, especially concerning the crucial high-voltage battery.

How Often Do Electric Cars Need Servicing?

The frequency of electric car servicing largely depends on the manufacturer's recommendations, typically falling into a pattern of once a year or every 10,000 to 20,000 miles, whichever comes first. It's always best to consult your vehicle's owner's manual or the manufacturer's official service schedule for precise intervals.

While the general maintenance pattern might seem similar to a petrol car, the specific checks carried out differ significantly. For instance, you won't be scheduling an oil change, but a comprehensive battery health check will be a fundamental part of the service. Some manufacturers utilise advanced 'Condition Based Servicing' systems, where the vehicle itself monitors various components and alerts you when a service is due, rather than adhering to a strict mileage or time interval.

Here's a look at typical service intervals and key checks for some popular EV models:

Adhering to these schedules is paramount for ensuring the longevity and optimal performance of your electric vehicle, particularly for safeguarding the warranty on the high-voltage battery system.

How Much Does It Cost to Service an Electric Car?

One of the most appealing aspects of electric vehicle ownership, beyond the reduced 'fuel' costs, is the typically lower maintenance expenditure. Servicing an electric car is generally cheaper than maintaining an equivalent petrol or diesel vehicle. The exact costs can vary based on the make, model, your location in the UK, and the specific service provider (e.g., main dealer vs. independent garage).

On average, you can expect the following price ranges for different levels of service:

• Interim service: £90 – £120
• Full service: £120 – £300
• Major service: £250 – £500

These figures represent a significant saving compared to ICE vehicles, which often incur higher costs due to more complex engine components, frequent fluid changes, and exhaust system maintenance.

To give you a clearer picture, here's an overview of typical annual servicing costs for some popular EV models available in the UK:

It's important to remember that these figures are averages and can fluctuate based on individual vehicle usage, geographical location, and whether you opt for a manufacturer-approved dealership or an independent EV specialist. The lower costs are primarily attributed to the simplicity of electric motors, which have far fewer moving parts, and the reduced need for consumable fluids like engine oil and traditional coolants.

What's Included in an Electric Car Service?

An electric car service focuses on different areas than a petrol or diesel car, but it's equally thorough. A typical EV service will generally include a comprehensive check of the following critical components:

• Battery Health Check: This is arguably the most crucial part of an EV service. Technicians will assess the health, efficiency, and overall performance of the high-voltage battery, often using diagnostic tools to identify any potential issues or degradation.
• Brake System Inspection: While EVs benefit from regenerative braking, which significantly reduces wear on brake pads and discs, these components still need regular checks for wear, corrosion, and proper function. Brake fluid levels and condition will also be inspected.
• Tyre Check: Tyres are vital for safety and performance. The service will include checking tyre pressure, tread depth, and overall condition for any signs of uneven wear or damage. Due to the instant torque and heavier weight of EVs, tyre wear can sometimes be more pronounced.
• Cooling System Maintenance: Many EVs use a dedicated cooling system to regulate the temperature of the battery and electric motor. This system's fluid levels and overall integrity will be checked to ensure optimal thermal management, which is critical for battery longevity and performance.
• Suspension and Steering Checks: Ensuring smooth handling and ride comfort, the suspension components, shock absorbers, and steering system will be thoroughly inspected for wear, damage, or alignment issues.
• Software Updates: Modern EVs are highly reliant on software. Some manufacturers offer over-the-air (OTA) updates, but others may require a service visit to apply the latest software versions for improved performance, efficiency, or new features.
• Cabin Air Filter Replacement: For passenger comfort and air quality, the cabin air filter (or microfilter) will be inspected and replaced if necessary.
• Lighting and Wipers: All exterior and interior lights, as well as wiper blades and washer fluid levels, will be checked for functionality.
• Charging Port Inspection: The charging port and cables will be inspected for any signs of wear or damage, ensuring safe and efficient charging.

These checks are designed to ensure every aspect of your electric vehicle is performing as it should, providing you with a safe, reliable, and efficient driving experience.

How Long Is An Electric Car Service?

One of the pleasant surprises for EV owners is that servicing an electric car is typically much quicker than servicing a petrol or diesel vehicle. Thanks to fewer moving parts and the absence of complex fluid changes, you'll spend less time waiting at the garage.

• Standard Service: A routine or interim service for an electric car usually takes between 30 minutes to 1.5 hours. This quick turnaround means you can often wait for your vehicle or drop it off for a short period.
• More In-depth Maintenance: If additional work is identified as necessary during the service, such as tyre replacements, brake component changes, or more extensive cooling system checks, the service might take a little longer, potentially a few hours or even overnight if parts need to be ordered.

The efficiency of EV servicing is a significant advantage, minimising disruption to your daily routine. The reduced complexity of the powertrain means less labour time and, consequently, lower costs.

Is an Electric Car Cheaper to Service Than an ICE Car?

Yes, unequivocally. Servicing an EV is typically 30-50% cheaper than servicing an equivalent petrol or diesel car over its lifetime. This is a key advantage of electric vehicle ownership and contributes significantly to the overall lower running costs.

The primary reasons for these substantial cost savings include:

• Fewer Moving Parts: The electric motor is far simpler than an internal combustion engine. There's no need for engine oil changes, spark plug replacements, fuel filter changes, or complex exhaust system maintenance. This drastically reduces the number of components that can wear out or require replacement.
• Less Brake Wear: As mentioned, EVs utilise regenerative braking, where the electric motor slows the car down and converts kinetic energy back into electricity for the battery. This system means the traditional friction brakes are used less frequently and less aggressively, leading to significantly reduced wear on brake pads and discs. Many EV owners report brake pad longevity far exceeding that of ICE vehicles.
• Lower Fluid and Filter Costs: Aside from brake fluid and potentially a specific coolant for the battery and motor, EVs require far fewer fluid changes. There's no engine oil, no transmission fluid (in the traditional sense), and fewer filters to replace, all of which save money on parts and labour.
• No Complex Gearbox Repairs: Most EVs use a single-speed transmission, eliminating the need for complex multi-gear gearbox maintenance or repairs that can be very costly in ICE vehicles.

While the initial purchase price of an EV might sometimes be higher than a comparable ICE car, these significant savings on servicing and 'fuel' (electricity) costs often make EVs a more economical choice over the vehicle's lifespan. However, it's crucial to note that while routine servicing is cheaper, battery-related repairs outside of the warranty period can be costly. This underscores the importance of regular servicing to ensure the battery remains in optimal condition and to catch any issues early.

Can I Service an Electric Car Myself?

For the most part, no. While you can certainly handle basic maintenance tasks on an electric car, just as you would with any vehicle, full servicing requires specialist knowledge and equipment. Simple checks like maintaining correct tyre pressure, topping up washer fluid, and replacing wiper blades are perfectly safe and encouraged DIY tasks.

However, anything beyond these basics, especially tasks involving the vehicle's electrical systems, should be left to qualified EV technicians. Electric vehicles contain high-voltage systems that can be extremely dangerous if not handled correctly. Attempting DIY repairs or maintenance on these systems without the proper training, safety equipment, and diagnostic tools could lead to severe injury or even death. For critical components like battery health checks, brake system servicing, and software updates that require access to the vehicle's onboard diagnostics, it is always best to visit a professional with the necessary expertise and certifications.

Electric Vehicle Battery Warranty Explained

When you purchase an Electric Vehicle (EV) or a Plug-In Hybrid Vehicle (PHEV), manufacturers typically provide a separate, extended warranty specifically for the high-voltage battery and the electric motor components. This warranty is often more comprehensive than the general vehicle warranty, reflecting the critical and expensive nature of these parts.

Commonly, this dedicated battery warranty extends for up to 8 years or 100,000 miles, whichever comes first. For instance, Volkswagen offers such a warranty for their electric vehicles, providing peace of mind to owners regarding the most vital component of their EV. Beyond just covering manufacturing defects, these warranties often include a guarantee on battery capacity retention over the warranty period. For example, Volkswagen assures that their EV batteries will retain at least 70% of their original capacity during the warranty term. This ensures that the vehicle's range and performance don't degrade excessively within the warranty period.

Adhering to the manufacturer's specified service schedule is usually a condition of maintaining this battery warranty. Skipping services or having work done by unqualified individuals could jeopardise your claim should an issue arise with the battery system.

Servicing Outside the Manufacturer Network (EU Block Exemption Rule)

A common concern for new car owners is whether taking their vehicle to an independent garage for servicing will invalidate their warranty. Thankfully, thanks to the EU Block Exemption Rule, which has been retained in UK law post-Brexit, vehicle owners have the freedom to choose where their car is serviced without fear of voiding the manufacturer's warranty.

This rule stipulates that as long as the independent garage uses manufacturer-approved parts (or parts of equivalent quality) and follows the manufacturer's specified service schedule, your vehicle's warranty remains intact. This is particularly relevant for PHEVs, as it means you can have the petrol or diesel engine serviced, or components like brake pads and discs replaced, at an independent garage. Crucially, this also applies to the electric motor(s) and battery warranty, provided the work performed on these systems meets the manufacturer's standards and is carried out by a qualified technician.

This provides consumers with greater flexibility and often more affordable servicing options compared to main dealer networks, fostering competition and choice in the automotive repair market.

What Work Can I NOT Get Done on My EV/PHEV?

While the EU Block Exemption Rule offers flexibility, there are specific areas where caution is advised, especially concerning high-voltage systems. For anything that requires the high-voltage system to be powered down, accessed, or for routine checks and maintenance of that specific system, it is highly recommended to use a qualified EV technician who is specifically trained and certified to work with high-voltage vehicles. This includes:

• Battery pack diagnostics and repair.
• Electric motor diagnostics and repair.
• Inverter and power electronics diagnostics.
• Any work that requires disconnecting or re-connecting high-voltage cables.

Attempting to perform these tasks without the necessary specialist knowledge, safety equipment, and training is extremely dangerous and could lead to serious injury or death. Furthermore, unauthorised tampering with these systems could indeed void your specific electric battery warranty. Always check the detailed terms and conditions of your vehicle's electric battery warranty to understand the precise limitations and requirements.

Where Can I Get an Electric Car Serviced?

As the number of EVs on UK roads grows, so do the options for servicing and maintenance. You have several choices, each with its own advantages:

• Manufacturer-Approved Dealerships: These are often the first choice for new EV owners. They have direct access to manufacturer-specific diagnostic tools, genuine parts, and technicians who receive regular training directly from the car maker. Servicing here ensures full warranty compliance, particularly crucial for the battery. However, they can sometimes be more expensive.
• Independent EV Garages: A growing number of independent garages across the UK are specialising in electric vehicle maintenance. They often offer more affordable rates than dealerships while still providing high-quality servicing. Look for garages that employ technicians certified in EV repair (e.g., IMI Level 3 or 4 in Electric/Hybrid Vehicle Repair and Maintenance) and have the appropriate safety equipment.
• Mobile Mechanics: Some mobile technicians are now specialising in EV maintenance, offering the convenience of performing services at your home or workplace. This can be a great option for routine checks and minor repairs, saving you time and hassle. Ensure they are properly qualified and insured for EV work.

Many reputable garages, like those found through platforms such as ClickMechanic, can help with repairs and servicing for your EV or PHEV, often providing a warranty on parts and repairs, allowing you to get vetted mechanics to carry out work at your chosen time and date.

Frequently Asked Questions (FAQs) About EV Servicing

Q: Is battery degradation covered under an EV service?
A: A battery health check is a standard part of an EV service, but the service itself doesn't fix degradation. Significant degradation is typically covered under the separate battery warranty, which guarantees a certain capacity retention (e.g., 70%) over a specified period (e.g., 8 years/100,000 miles).

Q: Do electric cars need an MOT?
A: Yes, just like petrol and diesel cars, electric vehicles over three years old in the UK require an annual MOT test to ensure they meet road safety and environmental standards. While they don't have emissions tests, checks on brakes, lights, tyres, steering, and suspension are still crucial.

Q: What about software updates? Are they part of a service?
A: Some manufacturers provide over-the-air (OTA) software updates directly to your vehicle, similar to smartphone updates. However, for some critical updates or if your vehicle doesn't support OTA, these may be applied during a scheduled service visit at a dealership or specialist garage.

Q: Are EV tyres different and more expensive?
A: EVs can be heavier due to their battery packs and deliver instant torque, which can sometimes lead to faster tyre wear. Many manufacturers recommend specific 'EV-optimised' tyres designed to handle the weight and torque, and often to reduce rolling resistance for better range. These can sometimes be slightly more expensive than standard tyres, but not always significantly so.

Q: Can I get a service plan for my electric car?
A: Yes, many manufacturers and some independent garages now offer specific service plans for electric vehicles. These plans allow you to spread the cost of servicing over several years, often at a reduced overall price, providing budgeting predictability and peace of mind.

Q: Do PHEVs (Plug-in Hybrid Electric Vehicles) have the same servicing as EVs?
A: PHEVs have both an electric motor/battery system and an internal combustion engine. This means they require servicing for both systems. They will still need traditional oil changes, spark plug replacements, and fuel filter changes for the petrol/diesel engine, in addition to the EV-specific checks like battery health and motor inspections. Therefore, PHEV servicing costs are typically higher than pure EVs but potentially lower than pure ICE vehicles if the petrol engine is used less frequently.
