How often should a car be serviced?
For many UK motorists, that glowing dashboard service light can spark a moment of dread. But understanding precisely how often a car should be serviced isn't just about ticking a box in the owner's manual; it's about safeguarding your significant investment and ensuring your family's safety on our busy roads.
In 2026, with the cost of living still pinching household budgets, skipping a vehicle service might seem like a smart, quick win. However, the long-term data from Regit and industry experts tells a very different story for petrol car owners and EV drivers alike.
From our extensive experience at Regit, drivers who stick to a strict car service schedule in the UK save an average of £1,200 over the lifetime of a five-year-old vehicle compared to those who only address faults as they crop up. This isn't just a number; it's tangible relief in your pocket. In this comprehensive guide, we'll break down the 'when', 'why', and 'how much' of car servicing in the current UK market, ensuring your options just got better when it comes to maintaining your vehicle.
Car service intervals
Historically, the go-to advice was to service your car every 3,000 miles. But thanks to leaps in modern engineering and advanced lubricants, this interval has stretched considerably. Today, the core recommendation from trusted organisations like the RAC and major car manufacturers is clear: a car should be serviced at least once every 12 months or every 12,000 miles, whichever milestone you hit first. This acts as your essential car service intervals baseline.
However, this is only the starting point. Your specific vehicle's needs are influenced by four key factors that every UK driver should consider:
- Age of the vehicle: Older cars often require more frequent lubrication checks and seal inspections to prevent common wear and tear issues.
- Annual Mileage: If you're covering 20,000 miles a year, you simply cannot wait for the 12-month mark. Your car will need attention sooner.
- Driving Style: Heavy city driving, with its constant stop-start cycles and lower speeds, puts more stress on an engine than long, smooth motorway cruising. Your car works harder in urban environments.
- Fuel Type: Electric Vehicles (EVs) have different servicing requirements compared to traditional Internal Combustion Engine (ICE) vehicles, especially those fitted with Diesel Particulate Filters (DPF).
Your car service explained: Interim vs full service vs major car service
Understanding exactly what happens during a car service helps justify the cost and highlights its immense value. Most reputable UK garages, from your trusted local independent to larger franchises like Kwik Fit or Halfords, typically offer three distinct levels of car servicing. Knowing these levels helps you decide what's right for your vehicle.
Interim service: Your mid-year check-up (6 months / 6,000 miles)
This service is specifically designed for high-mileage drivers who regularly cover more than 2,000 miles a month. Think of this as a vital mid-point check to ensure your vehicle remains roadworthy and reliable between full annual services.
What's typically included:
- An essential oil and filter change to keep your engine running smoothly.
- A thorough exhaust system check.
- Suspension inspection for safety and handling.
- A crucial visual brake check to spot any early wear.
What this means for drivers: This service significantly reduces the risk of engine sludge build-up, which can be a major issue for high-use vehicles, potentially saving you from costly repairs down the line.
Full service: The annual standard (12 Months / 12,000 Miles)
The full service is the standard annual requirement for the average UK driver. It encompasses everything included in an interim service but adds a comprehensive suite of over 40 additional checks and adjustments.
What's typically included:
- Air filter change for better engine performance and fuel economy.
- Extensive brake inspection, which involves removing the wheels for a more detailed look.
- Coolant top-up to maintain optimal engine temperature.
- Detailed checks for any fluid leaks, preventing potential damage.
According to research conducted by Direct Line Group in 2025, a concerning one in 10 UK drivers do not have an up-to-date service record. This dramatically increases the likelihood of an MOT failure, which can be a real headache and an unexpected expense.
Major service: The comprehensive overhaul (24 Months / 24,000 Miles)
The major service is the most comprehensive check your vehicle will receive. It covers all items within a full service but also includes the critical replacement of wear-heavy components that degrade over time and mileage, regardless of how meticulously you drive.
What's typically included:
- Replacement of spark plugs (for petrol cars) for optimal ignition.
- New fuel filters to ensure clean fuel delivery.
- Brake fluid replacement, which is critical for braking performance and safety.
What drivers need to know: This service is absolutely vital for maintaining your manufacturer's warranty on newer cars. Skipping this could void your warranty, leaving you exposed to significant repair costs. It’s also crucial for understanding the major car service cost in 2026.
The real cost of skipping: Why over 1 million drivers face risks
Recent data confirms a worrying trend: over one million UK drivers intentionally skipped their last service. While this might save between £150–£300 in the immediate short term, the long-term impact on your vehicle and your finances is severe. Let's delve into the skipped vehicle service consequences.
1. Resale value slump: A missing service stamp can cost you thousands
In our analysis of used car valuations, a missing service stamp can reduce a car's value by up to 20%. Buyers in 2026 are savvier than ever, using online tools and apps to meticulously check MOT and service history before even viewing a vehicle.
You can check your car's MOT history for free using Regit's MOT checker.
A 'Full Service History' (FSH) is, without doubt, the single most important document you possess outside of your V5C logbook when it comes to selling your car. It's an immediate red flag for potential buyers if it's absent.
2. Efficiency and fuel economy: Paying more at the pump
Old, degraded engine oil and clogged filters force your engine to work harder than it needs to. Statistics consistently show that a well-maintained engine can be up to 10% more fuel-efficient than one that has skipped its service. With petrol and diesel prices remaining volatile across the UK, a regular service effectively pays for itself at the pump, offering tangible relief.
3. The MOT link: Don't confuse the two
Many drivers mistakenly confuse an MOT check with a car service. An MOT is a legal safety requirement, ensuring your car meets minimum roadworthiness standards. A service, however, is a proactive mechanical health check designed to prevent issues. Here's a crucial statistic: a regularly serviced car is 60% less likely to fail an MOT on 'major' items such as brakes, emissions, or suspension components. This is good news for petrol car owners and EV drivers.
What this means for EV owners: A different service schedule
If you've made the smart transition to an electric vehicle, your service schedule changes significantly but certainly doesn't disappear. While EVs don't require oil changes or spark plugs, they do have their own specific maintenance needs that are critical for long-term health and optimal performance.
Key EV service considerations:
- Battery Health Reports: These are absolutely crucial for maintaining the resale value of your EV. A healthy battery means a higher selling price.
- Braking Systems: Due to regenerative braking, traditional brake pads might be used less frequently. However, they still need regular inspection to ensure they are functioning correctly and not seizing up.
- Tyre Wear: EVs are generally heavier than comparable ICE vehicles due to their battery packs. This added weight, combined with instant torque, often means more frequent tyre checks and potential replacements than equivalent petrol or diesel cars.
How much does a car service cost in 2026? UK pricing revealed
Based on Checkatrade’s 2026 data and our ongoing industry monitoring, pricing remains a key concern for UK drivers. Here’s a breakdown of estimated costs, designed to give you a clear picture of what to expect for your manufacturer service schedule.
| Service Type | Estimated Cost (Small Car) | Estimated Cost (SUV/Premium) |
| Interim | £125 - £160 | £180 - £230 |
| Full | £190 - £260 | £280 - £380 |
| Major | £300 - £400 | £450 - £600 |
Note: These prices are estimates and can vary significantly by region. For instance, drivers in London and the South East typically see 15-20% higher labour rates compared to other parts of the UK. This gives you a clear insight into the major car service costs in 2026.
Expert analysis: Manufacturer vs. independent garage debate
The good news is, thanks to 'Block Exemption' rules, you can service your car at any VAT-registered garage without voiding your manufacturer's warranty. This is provided they use manufacturer-approved parts and meticulously follow the official servicing schedule. However, for cars under three years old, a main dealer service stamp still carries a bit more weight and prestige in the used car market. For vehicles older than five years, a reputable local independent garage often offers better value for money, providing quality service without the main dealer price tag. Your options just got better!
Final verdict: Crafting your smart car maintenance strategy
Your options just got better with the rise of convenient service plans. Many manufacturers and third-party providers now allow you to spread the cost of servicing over affordable monthly payments. Often, these plans lock in today's prices, shielding you from future inflation – a real win for UK drivers.
Regit's recommendation:
- Always check your car's owner manual first. It contains the most specific manufacturer service schedule tailored to your vehicle.
- Treat your dashboard's 'service due' indicator as a command, not merely a suggestion. It's there to protect your vehicle.
- Even if you drive less than 5,000 miles a year, you still need an annual service. Engine oil degrades over time regardless of mileage, losing its protective qualities.
By staying proactive with your car's maintenance, you ensure your vehicle remains safe, efficient, and retains more of its value when the time comes to trade it in. This is truly good news for petrol car owners and EV drivers alike: regular maintenance remains the cheapest, smartest way to run a car in the UK today. It's a clear path to avoiding the significant skipped vehicle service consequences.
