A full car service from us starts at £250, takes around three hours, and comes with a 12-month or 12,000-mile guarantee. Engine oil to your engine's approved specification, an oil filter, sump plug washer, air filter, cabin filter and a proper brake inspection with the wheels off. That is what a full service should be. Not a 30-point checklist with half the items left blank.
Most people searching for this have one of three questions in their head: What am I actually paying for? How long will my car be off the road? And can I trust that whoever does it knows what they're doing? This page answers all three without the padding you usually get elsewhere.
What Is a Full Car Service?
A full car service is a scheduled maintenance appointment where a mechanic inspects and replaces the core components that keep your engine running cleanly and your brakes working safely. It is not a repair job. The mechanic isn't fixing something that's already broken they're replacing parts that wear out gradually, before they cause a problem you can feel or hear.
Think of it like this: your car's engine is constantly pushing oil, air, and combustion gases through a set of filters and seals. Over time those filters clog, the oil breaks down, and small seals degrade. None of this causes an immediate breakdown. But it compounds and that's when it becomes expensive.
How Is It Different from an MOT?
An MOT tests whether your car meets the legal minimum standard to be on public roads. It tests. It doesn't fix. If your brake pads are at 3mm above the legal minimum but getting close the tester will note it and move on. They won't change them.
A full service is the opposite. The mechanic removes your wheels, measures your brake pad thickness, inspects the callipers, and tells you exactly where you stand in millimetres, not vague phrases like "they're getting low." One is a legal test. The other is actual care.
You need both. They are not interchangeable.
Full Service vs Interim Service vs Major Service
These three terms confuse almost everyone, partly because garages use them inconsistently. Here's how they actually differ:
Interim service: oil and filter change plus basic safety checks. Designed for drivers covering high mileage who need a refresh at the 6-month mark. Does not include air filter, cabin filter, or a wheel-off brake inspection.
Full service: everything in the interim, plus air filter, cabin filter, sump plug washer, and a brake inspection with wheels removed. Recommended every 12 months or 12,000 miles.
Major service: everything in the full, plus spark plugs (petrol), fuel filter, brake fluid change, and additional system checks. Usually every 2 years or 24,000 miles, depending on the manufacturer.
If you're unsure which one your car needs, the manufacturer's service schedule is in your owner's handbook or on a sticker inside the driver's door frame. That document is worth checking before you book anything.
What Does a Full Car Service Include?
This is where garages get vague. They'll advertise a "50-point check" without specifying which points are inspections and which are actual replacements. So let's be direct about what should happen and what we do.
Engine Oil: The Specification Matters More Than People Realise
The engine oil is drained and replaced with fresh oil to the specification your engine is approved for. Not "suitable for most vehicles." Your engine's specific approved grade.
A 5W-30 oil is fine for many cars but wrong for others even cars that look similar on paper. The grade affects how the oil behaves at cold start, how it holds up at operating temperature, and how it interacts with seals and gaskets. Using the wrong grade won't destroy your engine overnight. But it does affect fuel economy and accelerates long-term wear in ways that don't show up until much later.
We look up the OEM specification for your registration before ordering anything. That's not extra effort it's just the correct way to do it.
Oil Filter: Changing the Oil Without Changing the Filter Is Pointless
The oil filter removes metal particles, soot, and combustion by-products from the circulating oil. Over a service interval it becomes saturated. A saturated filter either bypasses letting unfiltered oil through or restricts flow entirely.
Changing the oil without changing the filter means the fresh oil picks up contamination within minutes of the engine starting. We fit an OEM-grade filter matched to your vehicle, not the nearest generic equivalent in a multi-brand catalogue.
Sump Plug Washer: The 50p Part That Prevents a £1,000 Bill
The sump plug seals the bottom of your oil pan. Every time it's removed to drain the oil, the soft metal washer underneath it usually copper or aluminium deforms slightly under the torque. Reuse it two or three times and it may still seal fine. Reuse it six or eight times and you start to get a slow drip.
I've seen cars come in with a slow oil leak traced back to a reused sump plug washer. One had lost enough oil over three months to run the engine low without triggering a warning the owner only noticed because of a patch on the driveway. By the time we saw it, there was measurable wear on the main bearings.
A new washer costs around 50p. It gets replaced every service here. Some places don't bother ask directly before you book anywhere.
Air Filter: Clogged Filters Cost You at the Pump
Your engine needs a precise ratio of fuel and air to combust efficiently. The air filter stops road dust, insects, and debris from entering the combustion chamber. A restricted air filter forces the engine management system to compensate typically by running a richer fuel mixture which means higher fuel consumption and reduced performance.
On modern cars with direct injection engines, air filter condition also affects how cleanly fuel atomises during combustion. A clogged filter on a turbocharged engine can cause the turbo to work harder than it should under load.
We fit the filter your car's engine actually calls for, not the closest-fitting item from a generic range.
Cabin Filter (Pollen Filter): The Most Commonly Skipped Item
The cabin filter sits behind the dashboard and filters air entering the car's interior. It catches pollen, dust, bacteria, and fine particulates before they reach the cabin. A blocked cabin filter reduces airflow through the heating and air conditioning system, makes the blower work harder (increasing wear on the motor), and often causes a musty smell inside the car on first use of the heater.
It is the most frequently omitted item in budget service packages because it's out of sight, most drivers don't know to ask, and it's easy for a garage to leave it off the job card without the customer noticing. We replace it as standard. If you're getting a quote elsewhere, ask specifically whether the cabin filter is included.
Brake Inspection With the Wheels Off
A proper brake inspection means the wheels come off. Not a visual check through the spokes. The wheels are removed, the brake pads are measured with calipers, the disc thickness and condition are assessed, and the brake callipers are inspected for sticking pistons or corrosion.
You cannot accurately assess brake pad thickness without removing the wheel. Anyone telling you otherwise is either mistaken or cutting a corner. We give you the pad thickness in millimetres and tell you the manufacturer's minimum so you can make an informed decision, not take our word for it.
Full Car Service Checklist And How to Use It
Use this as your reference when comparing quotes. Every item below should be explicitly confirmed not implied before you agree to a booking anywhere.
Item | What Should Happen | Why It Matters |
|---|---|---|
Engine oil | Drained and replaced to your engine's manufacturer-approved specification | Wrong grade accelerates wear and affects fuel economy |
Oil filter | Replaced with OEM-grade filter matched to your vehicle | Saturated filter re-contaminates clean oil within minutes |
Sump plug washer | Replaced not reused | Prevents slow oil leaks that can drop oil level undetected |
Air filter | Replaced to your engine's required specification | Maintains fuel efficiency and combustion quality |
Cabin / pollen filter | Replaced (not just inspected) | Air quality inside the car; HVAC performance |
Brake inspection | Wheels removed; pads and discs measured; callipers checked | The only accurate method — visual checks through the wheel miss early wear |

3 Questions to Ask Any Garage Before You Book
You can tell a lot about a garage's standards from how they answer three specific questions. These aren't trick questions any competent garage should answer them confidently and without hesitation.
"Do you replace the sump plug washer as part of the service?"
The correct answer is yes, every time, without charge. A pause, a "we check it first," or a charge for this as an add-on tells you something about the rest of their process."What oil specification do you use and how do you confirm the right grade for my car?"
The correct answer is that they look up the manufacturer-approved specification for your registration. "We use a high-quality 5W-30 that suits most vehicles" is not a good answer."Does the brake inspection involve removing the wheels?"
It should. If the answer is anything other than yes, the brake inspection isn't a brake inspection — it's a visual check that will miss early calliper sticking and inner pad wear.
These three questions take thirty seconds to ask. The answers will tell you whether the garage is cutting corners before you've handed over your keys.
Does a Full Car Service Apply to Diesel Cars Too?
Yes. The checklist is the same. The oil specification is different and that difference matters more on a diesel than most people realise.
Modern diesel engines specifically those fitted with a diesel particulate filter (DPF) require a low-ash engine oil, typically classified under ACEA C1, C2, or C3. Standard petrol-grade oils contain sulphated ash compounds that accumulate in the DPF over time. A DPF blocked by incorrect oil ash deposits is not a cheap repair. A replacement DPF on a family saloon can run to £1,000 or more.
We confirm the correct oil specification for your registration before anything is ordered diesel, petrol, or mild hybrid. The service process is otherwise identical across fuel types.
How Long Does a Full Car Service Take?
Around three hours in most cases. Most customers drop off in the morning and collect before midday.
That estimate covers the standard service items. If something unexpected is found during the brake inspection a seized calliper, a disc worn below the manufacturer's minimum we'll contact you before doing additional work. Nothing is added to the bill without your approval first. The three-hour estimate does not include unplanned repairs.
If you need your car back by a specific time, mention it when you book. We'll tell you honestly whether that's achievable.
How Much Does a Full Car Service Cost?
A full car service at Technical Vehicle Solutions starts at £250. That covers engine oil to manufacturer-approved specification, OEM-grade oil filter, sump plug washer, air filter, cabin filter, and a brake inspection with wheels removed all with a 12-month or 12,000-mile guarantee.
The actual full service cost for your car depends on several factors. Here's how that plays out in practice:
A Ford Fiesta 1.0 EcoBoost typically comes in at or close to the £250 base: it takes a modest oil quantity, filters are widely available, and the engine is straightforward to work on.
A Volkswagen Golf 2.0 TDI usually sits closer to £280–£300. The engine requires a specific low-ash oil, takes more volume than the Fiesta, and the filter specification is tighter. The DPF-compatible oil grade costs more per litre.
A BMW 3 Series: particularly the later six-cylinder variants can push above £300 depending on oil capacity and specification. Long-life oil grades approved for BMW engines carry a premium.
These are illustrative figures, not fixed prices. We confirm the cost for your specific car and registration before the job starts so you know the number before you decide, not when you come to collect.
What Affects the Price?
Engine size and oil capacity: a 2.0-litre four-cylinder takes less oil than a 3.0-litre V6
Oil specification: low-ash diesel grades and manufacturer-specific long-life oils cost more per litre
Filter availability: filters for common vehicles are inexpensive; less common imports can be significantly more
Vehicle condition: seized drain plugs or corroded filter housings add time to the job
If a quote elsewhere is noticeably lower than £250, ask which items are actually included. The cabin filter and sump plug washer are the first things to disappear from a cut-price service.
How Often Should You Book a Full Car Service?
The standard interval is every 12 months or every 12,000 miles whichever comes first. Most manufacturers use this as the baseline for vehicles in normal driving conditions.
The 12-month trigger matters more than many people expect. If your driving is mostly short trips school runs, local errands, brief commutes the engine never fully reaches operating temperature. Moisture and combustion by-products accumulate in the oil more quickly than they would on longer motorway runs. Your oil can be significantly degraded well before the mileage figure suggests it needs attention.
On the other end: if you cover 18,000 miles or more per year, you'll hit the 12,000-mile mark before the year is up. An interim service at the mid-point makes sense in this case. Your owner's manual will specify whether your engine uses a fixed-interval or variable service schedule some modern engines calculate service intervals dynamically based on driving style and load.
What Is a Half Service (Interim Service) on a Car?
An interim service sometimes called a half service is a shorter maintenance check covering engine oil, oil filter, and a basic visual inspection of fluid levels, lights, and tyre condition. It does not include the air filter, cabin filter, or a wheel-off brake inspection.
It's a mid-year refresh for high-mileage drivers. Not a shortcut. Not an equivalent to a full service. If you cover 8,000 miles per year, a full service once annually is almost certainly sufficient an interim in between adds cost without meaningful benefit.
If you're covering 15,000+ miles per year, an interim at the 6-month or 7,500-mile mark keeps the oil fresh and gives you a safety check at the halfway point. That's the scenario it's designed for.
What a Full Service Does NOT Cover
Being direct about this matters. Some customers arrive expecting a full service to cover things it doesn't and some garages don't clarify this until the collection conversation.
A full car service does not include:
MOT testing : a separate appointment (some garages offer them together, but they're separate processes)
Brake pad or disc replacement : the inspection identifies condition, but replacement is a separate job quoted separately
Tyre replacement or tracking alignment
Spark plug replacement: typically a major service item on petrol engines
Brake fluid change: usually a major service or biennial item
Air conditioning regas
Timing belt or chain inspection: unless specifically listed on your service quote
If anything flagged during the inspection needs attention, you'll hear about it with a clear explanation and a separate quote before we do anything additional.
Why Regular Servicing Actually Matters
The benefits of a full service aren't immediately visible. The car still starts. It still drives. Which is exactly why people skip it and why the cost of skipping it tends to arrive as a surprise.
Oil protects the engine only when it's clean. Degraded oil loses viscosity and becomes acidic. The film that separates moving metal surfaces thins. Wear accelerates in ways that don't show up until a bearing or a camshaft tells you about it at the worst possible time.
A blocked air filter costs you money at every fill. Even a 10% restriction in airflow affects combustion efficiency. On a car doing 12,000 miles per year, that adds up at the pump before you notice anything at the wheel.
A stuck brake calliper turns a £120 pad change into a £400 disc-and-pad job. Callipers stick gradually. The first sign is uneven pad wear something only visible when the wheels come off. Left another service interval, the pad wears to metal and scores the disc.
A complete service history is worth real money at resale. A documented full service history stamps or digital records consistently adds to a car's private sale value. A gap in that history, or a record of missed intervals, reduces buyer confidence and cuts the asking price accordingly.
None of this happens suddenly. All of it compounds. That's the point.
Why the Oil and Filters We Use Are Different
Most people assume all garages use equivalent materials. They don't and the difference isn't always obvious from the outside.
We use engine oil to the specification your engine is approved for. We look up the OEM grade for your registration and order accordingly not a "suitable for most vehicles" multi-grade. The air filter and cabin filter are OEM-grade items matched to your car's specification: correct dimensions, correct filtration media, correct flow rate. An undersized or low-density aftermarket filter may fit the housing but won't perform the same function.
The sump plug washer is replaced every time. That point has been made already but it's worth repeating because it costs almost nothing and prevents the kind of slow oil loss that does real damage.
Everything is covered by a 12-month or 12,000-mile guarantee. If anything related to the service fails within that window, we fix it.
Frequently Asked Questions About Full Car Service
Will servicing with you void my manufacturer's warranty?
No, provided the service is carried out to the manufacturer's specification, using the correct oil grade and OEM-grade parts, your warranty remains valid. EU and UK block exemption regulations mean you are not required to use a franchised dealer for routine servicing. The key is that the correct specification is used and the service is documented. We record all work on the job card and stamp your service book.
If your car is very new and under a specific dealer warranty scheme with additional conditions attached, check the warranty documentation directly but for the vast majority of cars, an independent garage using the right specification parts is perfectly fine.
What's the difference between a full service on a hybrid and a standard petrol car?
For most mild hybrids (48V systems), the service process is essentially the same as a petrol car — the oil, filters, and brake inspection apply as normal. The regenerative braking system on hybrids typically means brake pads wear more slowly than on conventional cars, since the motor assists with deceleration. This doesn't mean the brake inspection is less important calliper condition and disc surface still need to be checked.
Full hybrids and plug-in hybrids (PHEVs) may have additional considerations around the high-voltage battery system, but routine servicing of the combustion engine side follows the same checklist. We confirm the correct oil specification for your hybrid's engine before the job starts.
My service light is on but I only did 6,000 miles since the last service. Do I still need one?
Possibly yes. Many modern vehicles use a condition-based or time-based service trigger, not just a mileage counter. If your driving is mostly short local trips, the car's system may flag a service based on oil condition or elapsed time rather than distance. Short journeys prevent the engine from fully reaching operating temperature, which means moisture and combustion by-products build up in the oil faster than the mileage figure implies.
The service light should not be reset and ignored. If the car is calculating it's time, it's worth acting on it even if the mileage seems low.
Can I bring my own oil or filters to save money?
We'd rather source them ourselves. Not because of the margin but because we can verify the specification is correct for your car before we order. If you bring oil or a filter purchased elsewhere, we can't guarantee it's the right grade or a genuine OEM-quality part, which affects our ability to stand behind the work under guarantee. It's not something we offer as an option.
What happens if something is found wrong during the service?
We contact you before doing anything beyond the booked service. If the brake inspection shows pads at 3mm and discs with heat cracking, we'll call you, explain what we found, give you the measurements, and quote for the additional work separately. Nothing is added to the job without your agreement first. If you decide not to proceed with the additional work, we'll note it on the job card and let you make an informed decision about timing.
Is there a difference between a full service for a new car and an older car?
The checklist is the same. The practicalities can differ. Older vehicles — particularly those over 8 to 10 years — sometimes have corroded filter housings, seized sump plugs, or worn threads on the drain point that add time to the job. We factor this in during the service and let you know if anything unexpected is encountered. Newer cars under an active manufacturer service plan may have specific interval requirements or oil types — we check these before starting.
Final Thoughts
A full car service done properly costs you less in the long run than one done carelessly or one skipped altogether. The difference between a thorough service and a box-ticking exercise isn't always visible from the outside, which is why the three questions in this guide are worth asking before you commit to any garage.
To summarise what matters most:
The standard interval is 12 months or 12,000 miles whichever comes first, and the time trigger matters as much as the mileage for short-distance drivers
A full service at Technical Vehicle Solutions starts at £250, takes around three hours, and is guaranteed for 12 months or 12,000 miles
Oil to your engine's approved specification, OEM-grade filters, and a sump plug washer that's replaced every time not reused
The brake inspection involves removing the wheels not a visual check through the spokes
The cabin filter is included as standard it's the first thing to disappear from a budget service
