How Long Does a Car Service Take & 4 More Questions Answered

How long does a car service take? It’s a question many UK drivers ask, especially when juggling busy schedules. The answer depends on the type of service your car needs, from a quick interim check to a more detailed major service. But no matter the type, regular servicing is key to keeping your car safe, efficient, and reliable. 

In this guide, we’ll break down service times, what’s included, and how to avoid delays or surprises.

Let’s get started!

How Long Does a Car Service Take?

On average, a car service takes between 1 and 3 hours, depending on the type of service and your car’s condition. While electric vehicles have their own service needs, let’s focus on regular petrol and diesel cars that most UK drivers use. 

First, there is the interim service, the quickest option. It’s perfect if you drive a lot or want a quick check between full services. This is usually done every 6 months or 6,000 miles, though some drivers prefer doing it every 3 months for peace of mind.

Next is the full service, the most common one. It includes everything from the interim check and more. You’ll typically need this once a year or every 12,000 miles.

Lastly, the major service is the most in-depth. It’s recommended every 2 years or 24,000 miles and involves detailed checks and part replacements.

Keep in mind that car servicing is important, and you shouldn’t miss it. Otherwise, it will cost you a lot of money. 

How Long Does an Interim Car Service Take?

An interim car service usually takes between 45 and 90 minutes. It’s the quickest type of service, which is great if you’re short on time. Some garages let you drop off your car and pick it up later, while others have waiting areas if you’d rather stay until it’s done.

If everything’s running smoothly, you’ll likely be back on the road within the hour. But if the mechanic finds any problems that need fixing right away, it might take longer – so it’s smart to leave yourself some extra time, just in case.

What’s Included in an Interim Service?

This service focuses on basic checks and maintenance to keep your car in good shape between full services. It usually includes:

• Oil and oil filter change
• Brake, steering, and clutch checks
• Tyre pressure and tread inspection
• Lights, wipers, and fluid top-ups
• Visual inspection under the bonnet
• Safety checks like seatbelts and the horn

It’s ideal for high-mileage drivers or those doing lots of short trips. Otherwise, a yearly full service might be enough.

How Long Does a Full Car Service Take?

A full car service usually takes about two to three hours. It’s more in-depth than an interim service, so it naturally takes longer. Many garages let you drop your car off and collect it later, or you can wait in a customer area if you prefer.

If your car is in good condition, the service might be done in around two hours. But if the mechanic finds anything that needs fixing, it could take longer. So it’s smart to allow some extra time just in case.

What’s Included in a Full Service?

A full service gives your car a thorough check from top to bottom. It usually includes:

• Changing the air filter, fuel filter, and spark plugs
• Shock absorbers and wheel bearings inspection
• Coolant hose and radiator testing
• Air conditioning and electrical inspection
• Fluid top-ups (coolant, brake fluid, power steering, screen wash)
• Exhaust system and seatbelt safety check
• Battery health check and charging system inspection

This service is recommended annually for most drivers, especially those covering around 12,000 miles a year. It helps catch wear and tear early and keeps your car in peak condition.

How Long Does a Major Car Service Take?

A major car service usually takes around four hours, making it the longest and most detailed type of routine car service. It covers everything from a full service, plus additional checks and part replacements – even if those parts aren’t showing signs of wear. That’s why it naturally takes more time.

Most garages let you drop your car off and collect it later, but some have waiting rooms if you’d rather stay. If your car is in good condition, four hours is about right. But if the mechanic finds issues or needs to replace extra parts, it could take longer.

What’s Included in a Major Service?

A major service covers everything in a full service, plus extra replacements and checks designed to keep your car in peak condition over the long term. Typical inclusions are:

• Engine oil and filter change
• Replacing the air filter, fuel filter, and spark plugs
• Brake fluid change (recommended every two to three years)
• Cabin/pollen filter replacement
• In-depth checks on brakes, suspension, steering, and wheel bearings
• Testing the exhaust, battery, and cooling system
• Radiator and hose inspection
• Full diagnostic checks of the engine management and electronics
• Lubricating moving parts like the gearbox and engine.
• A test drive to make sure everything’s running well

Major servicing is recommended every 24 months or 24,000 miles, helping you avoid costly repairs and maintain your car’s long-term health.

What Factors Affect How Long a Car Service Takes?

The time it takes to service your car can vary depending on a few important things. Knowing these factors can help you plan ahead and avoid any surprises.

a. Type of Service Needed

The type of service is a big factor. An interim service is the quickest and usually takes about 45 to 90 minutes. A full service is more detailed and typically lasts two to three hours. A major service takes the longest, often around four hours, since it includes extra checks and part replacements.

b. Make and Model of the Car

Some cars are quicker to work on than others. Simple models are easier to service, but luxury or high-tech vehicles like BMWs may take longer because of their advanced systems.

c. Parts Availability

If your car needs new parts and they’re not in stock, the service might be delayed while the garage waits for delivery. This is more common with rare models or specialised components.

d. Mechanic’s Experience and Garage Workload

Experienced mechanics can complete the job more efficiently. Also, if the garage is really busy, like during peak times or holiday seasons, services may take longer simply because there are more cars waiting.

e. Extra Repairs or Checks

Sometimes, a service uncovers problems that weren’t expected. If repairs or extra diagnostics are needed, this will add more time to the visit.

f. When You Book Your Appointment

Booking your car service during busy times of the week, such as Fridays or just before holidays, can lead to delays. Try booking on quieter days for faster turnaround.

How to Avoid Surprises or Delays for Your Car Service?

Getting your car ready for a service can save you time, money, and stress. With just a bit of preparation, you can make the whole process quicker and more straightforward.

Here are some helpful tips to keep things running smoothly:

a. Book Your Appointment Early

Garages get busy, especially around weekends or holiday periods. Booking ahead of time ensures you get a convenient slot and helps the garage plan their schedule.

b. Bring Important Paperwork

Make sure you take your service book, MOT certificate, and any recent repair receipts. These give the mechanic a full picture of your car’s history and help avoid unnecessary work.

c. Bring the Locking Wheel Nut Key

If your car has alloy wheels with locking nuts, don’t forget to bring the special key. Without it, the mechanic can’t remove the wheels to check your brakes and tyres.

d. Top Up Your Fluids

Check the basics like engine oil, coolant, brake fluid, and screen wash before your visit. Topping them up yourself is quick and can save you extra charges at the garage.

e. Write Down Any Concerns

If you’ve noticed warning lights, strange sounds, or anything unusual with the way your car drives, make a note. Share this with your mechanic to help speed up the diagnosis.

f. Make Sure Your MOT Is Up to Date

If your MOT has expired, it could delay your service. Check your MOT expiry date in advance and renew it if needed.

g. Talk About Repairs Beforehand

If you won’t be waiting at the garage, let the staff know you want to be contacted before any extra repairs are done. This gives you time to approve the cost or get a second opinion.

Following these steps makes life easier for your mechanic and helps keep your car service on track with no unexpected delays.

Frequently Asked Questions

Is MOT and Car Servicing the Same?

It’s a common question, and the answer is no. An MOT and a car service are two very different things, even though both help keep your car safe and roadworthy.

An MOT (Ministry of Transport test) is a legal check that all cars over three years old must pass every year. It makes sure your car meets the minimum safety and emissions standards set by the DVSA. During the test, a certified mechanic checks things like your brakes, tyres, lights, seatbelts, steering, and exhaust system.

If your car passes, it means it is legally safe to drive. However, an MOT does not assess the overall health or performance of your car. It only confirms that it meets the basic legal standards.

A service is routine maintenance. It is not a legal requirement, but it is strongly recommended. It includes changing the oil and filters, topping up fluids, checking the brakes and tyres, inspecting the battery, and making sure everything is working properly.

How long does an MOT take? 

An MOT test usually takes between 45 minutes and an hour. The exact time can vary depending on your car’s make, model, condition, and how busy the garage is. If your car passes without any problems, you can often take it home the same day. But if it fails, repairs and a retest will take longer.

Can a car service detect all problems?

A car service covers a lot, like oil changes, fluid top-ups, brake checks, and tyre inspections. But it won’t catch every issue. Some problems, like electrical faults or engine glitches, may need more detailed diagnostics. Still, regular servicing helps prevent most major breakdowns and keeps your car in great shape.

Can I skip servicing my car?

It’s not a good idea to skip your car service. Even though it’s not a legal requirement like an MOT, regular servicing is important for your car’s health. Skipping services can lead to bigger problems, expensive repairs, or even void your warranty. Servicing helps catch small issues early and keeps your car safe, reliable, and running smoothly.

Final Thoughts: How Long Does a Car Service Take?

A car service keeps your vehicle running safely, efficiently, and reliably. From oil changes to brake checks, each step helps catch small issues before they turn into expensive repairs.

Sticking to your service schedule can extend your car’s life, improve performance, and even boost fuel economy. Whether it’s an interim, full, or major service, staying on top of maintenance is always worth it.

But if your car is becoming too costly to maintain, it might be time to think about selling.
