Vehicle Warranty Tracking: How to Keep Your UK Car or Van Cover Valid in 2026

Key Takeaways

• Most new UK cars come with a 3-year manufacturer warranty, typically capped at 60,000 miles (Ford), with Mercedes-Benz offering 3 years at unlimited mileage and Renault running unlimited for the first 24 months then capped at 60,000 miles to 3 years.
• Vans split the warranty into two phases: usually 12 months unlimited mileage, then to month 36 capped at 100,000 miles (Vauxhall Vivaro), or up to 100,000 miles total for the Renault Trafic.
• On top of any manufacturer warranty, the Consumer Rights Act 2015 gives you a 30-day right to reject, a one-repair rule between days 31 and 6 months, and refunds payable within 14 days of the trader agreeing.
• Under the retained Motor Vehicle Block Exemption Regulation (in force until 31 May 2029), a manufacturer cannot void your warranty just because you used an independent garage, as long as the garage followed the manufacturer's schedule, used matching-quality parts and fluids, and stamped the service book.
• Extended warranties from FCA-regulated providers typically cost £165 to £630 a year depending on car and policy tier; whether they pay off depends on how close the cover ends to your annual mileage and service pattern.

If you bought a new car or van in the last three years, the single most expensive document you own is probably the warranty booklet, and the easiest way to lose hundreds or thousands of pounds is to let it expire without noticing or to miss a service deadline that voids it. This is not a hypothetical: a major dealer-system component (gearbox, dual-mass flywheel, infotainment unit) failing 14 days after the warranty ends is a five-figure problem you would have paid nothing for two weeks earlier.

The warranty rules are not difficult, but they are scattered. The manufacturer sets the length and mileage cap. The Consumer Rights Act 2015 sits underneath them as your statutory floor. The retained Block Exemption Regulation governs where you can get the car serviced without losing cover. And the Financial Conduct Authority oversees the extended-warranty market as motor and breakdown insurance.

This guide pulls all four into one place, with current 2026 figures, so you (or whoever runs the vehicles in your business) can stop hoping the dates are noted somewhere and start tracking them properly. If you also need to think about service intervals in parallel, our van service intervals guide is a good companion read.

How long does a UK new car or van warranty actually last?

Most UK new car warranties run 3 years, capped by either mileage or time, whichever comes first. Vans usually shift to a two-phase structure: unlimited mileage for the first 12 months, then a hard mileage cap from month 13 to month 36. The cap is the part owners forget, because the time clock is in your diary and the mileage clock is in the dashboard.

Here is the current picture for the big sellers, all figures taken directly from manufacturer UK warranty pages:

Cars

• Ford: 3 years or 60,000 miles, whichever comes first.
• Vauxhall (cars): 3 years, unlimited mileage in year 1 (with Vauxhall Roadside Assistance included), then years 2 and 3 covered to a normal limit.
• Mercedes-Benz (cars): 3 years, unlimited mileage.
• Renault (cars registered from 1 January 2023): Unlimited mileage for the first 24 months, then capped at a total of 60,000 miles or 3 years, whichever comes first.

Vans

• Ford Transit / Transit Custom: 3 years or 100,000 miles depending on model line, with the same caveat that the first phase is time-limited and the second is mileage-capped. Check your specific build sheet.
• Vauxhall Vivaro (commercial): Unlimited mileage for the first 12 months; from month 13 to month 36 the warranty is capped at 100,000 miles total from first registration (60,000 miles for the Vivaro Life passenger variant).
• Renault Trafic and other LCVs registered from 1 January 2023: Unlimited mileage for the first 24 months, then to 3 years or 100,000 miles total, whichever comes first.
• Mercedes-Benz Sprinter and Vito: 3 years, broadly aligned with the cars but with model-line specifics; the Mercedes-Benz Vans UK warranty page is the definitive source for the exact variant you bought.

For high-mileage trades (multi-drop courier, plumbing, mobile mechanic, delivery), the mileage cap usually bites first. A van doing 35,000 miles a year on a 100,000-mile cap is out of warranty before the 36-month mark, and there is no notification: the cover stops applying the moment the next service shows an over-cap reading. That is why a small-fleet owner who tracks renewal dates but not odometer readings is still exposed.

Your legal rights under the Consumer Rights Act 2015 (these are separate)

The Consumer Rights Act 2015 gives every UK buyer a set of statutory protections that sit on top of the manufacturer warranty and the dealer warranty. They do not replace each other. So even after the manufacturer warranty has ended, you may still have a CRA claim against the dealer who sold you the vehicle. The three pillars to remember:

Within 30 days of purchase, you have a short-term right to reject the vehicle if it is not of satisfactory quality, fit for purpose, or as described. You hand it back, you get a refund. The trader must pay any agreed refund "without undue delay" and at the latest within 14 days of agreeing it.

Between 31 days and 6 months, the dealer gets one attempt to repair or replace. If that one attempt fails, you can reject the vehicle and claim a refund (which can be slightly reduced for any use you have had). The legal presumption in this window is that the fault was present at the time of sale: the burden is on the dealer, not on you, to prove otherwise.

After 6 months, the burden of proof flips to you. To claim, you usually need an independent mechanic's report or expert opinion showing the fault existed (or was developing) at the point of sale. Citizens Advice and the Motor Ombudsman both publish templates for this.

The practical upshot is that a warranty booklet that says "12 months" from the dealer does not cancel out your Consumer Rights Act floor. Citizens Advice puts it bluntly: a warranty or guarantee is "in addition to your legal rights", not a substitute. If a dealer ever tells you their warranty wording overrides the Act, that is wrong, and it is a flag to file the complaint properly.

What actually voids a manufacturer warranty?

Three things reliably end a manufacturer warranty before its stated term: skipping or significantly delaying a scheduled service, using non-matching-quality parts or fluids, and modifying the vehicle in ways that affect powertrain or safety systems. Day-to-day items (wiper blades, tyres, brake pads, accidental damage) are wear items or covered by other policies, and most warranties never covered them in the first place.

Missed and late services are the most common voider

The standard UK guideline is a service every 12 months or every 12,000 miles, whichever comes first, though the actual schedule is whatever the manufacturer's book says for your specific model. Miss one service and most dealers will allow a reasonable tolerance (typically within a few weeks or a few hundred miles). Miss the service significantly, and the warranty claim against a related component can be refused on the basis that the maintenance condition was not met.

The defensible position is simple: keep services within the manufacturer's specified interval, with documented evidence. A stamped service book, an itemised invoice, and a record of the mileage at service all need to be available if you ever lodge a claim. If you are running a fleet, that is the entire job: a paperless record system that ties each invoice to the right vehicle on the right date is what stands up to a manufacturer's audit. Our vehicle maintenance schedule guide lays out the cadence post-by-post.

Wrong parts and fluids

Manufacturers can refuse a warranty claim if the failed component is downstream of a part or fluid that did not meet the original specification. The Block Exemption Regulation tightened the language here in 2023, updating the wording to cover "fluids" (not just lubricants). For an engine claim, that means oil grade, coolant, and even transmission fluid have to match what the book says.

Independent garages do not void your warranty

Under the retained Motor Vehicle Block Exemption Regulation, in force in the UK until 31 May 2029, a manufacturer cannot insist that you use only a main dealer to keep the warranty valid. Any qualified garage can do the work, provided it follows the manufacturer's service schedule, uses matching-quality parts and fluids, and stamps the service record properly. The RAC, Trading Standards and Citizens Advice all confirm this, and the legal position is the same for cars and vans.

The catch is paperwork. If you take a van to an independent for a service, you must end up with an itemised invoice showing the parts used (with part numbers), the fluids used, the mileage at service, and a stamp or signature against the manufacturer's schedule item. A handwritten "serviced" receipt is not enough to defend a warranty claim three years later.

Extended warranties: are they worth it?

Extended warranties (sold as motor and breakdown insurance, regulated by the Financial Conduct Authority under the wider general insurance regime) are a separate product from the manufacturer warranty. They typically kick in when the manufacturer cover ends and pay out for specified component failures. UK premiums in 2026 sit in a wide band:

• Small petrol cars (Fiesta, Aygo class) at 3 years old and 30,000 miles: around £165 for basic cover, up to about £500 for premium tiers.
• Mid-range and executive (3 Series, A4 class): around £210 for basic, up to around £630 for premium.
• Older vehicles or higher mileage: prices rise sharply, and many providers cap eligibility at a maximum age (often 10 years) or a maximum mileage (often 100,000 to 120,000 miles).

Whether the cover pays off is a maths question, not a marketing one. The two variables that matter are component failure cost (a modern dual-mass flywheel can be £1,500 to £2,500; an automatic gearbox much more) and policy exclusions. Pay close attention to consequential damage, "wear and tear" wording, and labour rate caps, because those are where claims are most often refused.

The FCA-regulated piece is the safety net: an extended warranty from a regulated MBI provider is covered by the Financial Ombudsman Service if you have a dispute, and the Financial Services Compensation Scheme if the provider goes bust. A "warranty" sold informally by a small dealer outside the regulated regime gives you neither. Always check the FCA register before buying.

The five dates every car or van owner should be tracking

The work of warranty tracking is the work of holding five dates and one number in one place per vehicle. If any single one of those slips, the cover is either useless or already gone. The list is the same whether you have one car or twenty vans:

1. Warranty expiry date (e.g., manufacturer expiry on day 1,095 from first registration).
2. Warranty mileage cap (the number, not the date; check at every service).
3. Next scheduled service date (or mileage, whichever comes first).
4. MOT expiry date (a missed MOT does not directly void a warranty, but it is the same audit trail and the same fine pool).
5. Extended warranty start date and expiry date, if you bought one.

The number to track alongside those dates is the odometer at last service, because that is the figure a manufacturer will look up if you ever file a claim. For a small fleet running multiple vehicles past 60,000 or 100,000 miles, this is also the number that decides which van still has cover and which one has dropped off.

For one personal vehicle, a kitchen drawer or a phone reminder is usually enough. For a working van that is the lifeblood of a business, or for a fleet of 3 to 30, the dates have to live somewhere a holiday cover or a new admin can pick up. That is the entire job of Autodue's service management and insurance tracking features: every vehicle, every date, one screen, no kitchen-drawer paper trail.

Building a warranty record that survives a claim

A warranty claim is won or lost on documentation. The manufacturer or extended-warranty provider has to be able to verify, in their format, that the service schedule was followed, that the correct parts were fitted, and that the vehicle has not been used outside the terms of cover. Three habits keep that record airtight:

Keep every invoice as a PDF, not a photo or a paper receipt buried in a glove box. A photo of a crumpled receipt is hard to read and easy to lose. A PDF named with the date, vehicle reg, and mileage at service is a one-second lookup. Most accounting and fleet tools (including expense tracking in Autodue) accept a phone-camera capture and store it as a PDF tied to the vehicle.

Record the odometer at every service, every fuel stop into a fleet system, and every defect note from a walkaround. Mileage is the most-disputed figure in warranty claims, because manufacturers cross-check the figure on the claim with the figure at the most recent service. If the two do not line up, the claim takes longer. If the mileage at service was wildly wrong (a clerical error, a stuck odometer between cars), the claim can fail outright. Tying odometer to defect notes is also useful for the audit picture that satisfies a DVSA roadside stop, as covered in our vehicle maintenance system guide.

Check for outstanding manufacturer recalls every 6 months. UK manufacturer recalls are listed on the gov.uk recall checker, and an unactioned recall can become a contributing factor in a refused claim if the recalled component is what failed. Vehicles with multiple owners and incomplete service history are the most exposed here: the recall letter went to a previous keeper who never forwarded it.

What changes for fleet operators with more than one vehicle

For a fleet running 5 to 50 vehicles, warranty tracking stops being a personal admin job and becomes a compliance line item. A typical 10-van trade fleet is staggered across three or four model years, two or three manufacturers, and a wide spread of annual mileages, which means at any given moment some vehicles are in warranty, some are out, and some are on extended cover. A single shared spreadsheet that nobody owns is the failure mode. The losses show up at the worst possible time: a van off the road for a week with a fault that would have been free to fix 200 miles earlier.

The operational habit that solves this is to bind warranty data to the vehicle record itself, not to the buying paperwork. Each van in the fleet record gets three fields: original registration date, warranty cap mileage, and extended warranty (if any) start and end. Each service event updates the running odometer against the cap. A reminder fires when the vehicle is within 30 days or 5,000 miles of expiry, so the operator either books the still-covered repairs that have been quietly piling up, or makes an informed call about whether to buy extended cover before the gap opens.

That is exactly the pattern Autodue is built around: reminders that fire at 90, 60, 30 and 7 days for time-bound deadlines, and the underlying vehicle record holds the mileage and service history that a manufacturer audit would need. The walkaround layer (fixed 19-point van check, 27-point HGV check) generates the defect record that supports a claim, with timestamps and photos already attached.

The bottom line

Warranty tracking is not glamorous, and most owners do not think about it until the day the bill arrives. The work is small and repeatable: the five dates, the odometer number, the receipts as PDFs, and a service routine that follows the book. The savings are not small. A single voided claim on a modern powertrain is enough to fund a year of an entire fleet's reminder software.

If you have one vehicle, set the four reminders this week and keep the service book in the same place as the V5C. If you have a fleet, stop trusting the spreadsheet and put the warranty data inside the vehicle record so the next admin or the holiday cover can read it without ringing you.
