Van Service Intervals: How Often Should You Service Your Van?

Key Takeaways

• Almost every modern van service interval is set as "X miles or Y months, whichever comes first". Time matters as much as mileage. A van that does 6,000 miles a year still needs an annual service.
• Ford Transit and Transit Custom: every 18,000 miles or 12 months. Mercedes Sprinter: roughly every 20,000 miles, alternating between Service A (oil and filter) and Service B (oil, filter, brake fluid, pollen filter). VW Transporter and Crafter: 12,000 miles / 12 months on Fixed, or up to 18,000 miles / 24 months on Flexible. Stellantis vans (Vivaro, Expert, Dispatch): 25,000 to 30,000 miles or 2 years. Renault Master and Nissan Interstar: 25,000 miles or 2 years.
• Skipping or stretching a service voids most manufacturer warranties, hurts resale value, and is the most common preventable cause of expensive engine and gearbox repairs.
• Variable (long-life) intervals look cheaper on paper but only suit drivers doing long, steady motorway miles. Short-trip and stop-start use should stay on a fixed annual schedule.
• Service date and mileage are both moving targets. The fleets that never miss one record both, set reminders against both, and book the service the moment the earlier of the two is within 4 weeks.

If you drive a van for work, the service interval is one of the few maintenance numbers you can actually plan around. Skip it and the costs compound: a £250 service that should have happened becomes a £2,500 turbo, an injector, or a clutch. Hit it on time and your van running costs stay close to predictable.

The problem is that "how often should you service your van?" does not have one answer. Every manufacturer sets its own van service interval, every engine variant tweaks it, and most modern vans now offer two different schedules depending on how the van is driven. The Transit service schedule looks nothing like the Sprinter service interval, which looks nothing like the long-life option on a Crafter.

Here is the rule that runs across all of them, the actual interval for each major UK van, and what a service should include at each visit.

"Whichever comes first": the rule that matters

Almost every van service interval in the UK is published as two numbers: a mileage figure and a time figure. The service is due when you hit the first of the two.

A Ford Transit Custom's interval is 18,000 miles or 12 months, whichever comes first. A driver covering 30,000 miles a year will hit the mileage trigger in about seven months. A driver covering 6,000 miles a year will hit the time trigger long before the mileage one, but the service is just as necessary, because oil degrades on a calendar, not a counter.

The reason both numbers exist: engine oil breaks down whether the engine runs or not. Acids form, additives deplete, moisture builds up, and the oil's ability to protect the engine drops. Twelve months in a sump that does 6,000 miles is harder on the oil than 18,000 miles in six months, because of the temperature cycling and the moisture. The time interval exists to catch the low-mileage drivers who would otherwise let the oil sit for two or three years.

If a garage tells you "you've only done 8,000 miles, you don't need the service yet", and your van is over 12 months past the last one, find a different garage.

What's actually in a van service

Garages vary, but the work breaks down into two repeating tiers across most manufacturers.

Minor or interim service. Engine oil and oil filter change. Top-up of all under-bonnet fluids (coolant, brake fluid, washer fluid, power steering fluid where fitted). Visual check of brakes, tyres, lights, suspension, and exhaust. A road test. This is roughly £150 to £250 at an independent garage, more at a main dealer.

Major or full service. Everything in the minor service, plus air filter, fuel filter, and pollen/cabin filter replacement. Brake fluid renewal (every 2 years on most modern vans). A more thorough inspection of brakes, steering, and suspension components. Spark plugs on petrol vans. Typically £300 to £500 at an independent, more at a main dealer.

A few items run on their own clocks regardless of the regular service:

• Cambelt (timing belt). Manufacturer-specified, usually 60,000 to 120,000 miles or 5 to 10 years. Expensive (£400 to £800 fitted) and non-negotiable. A snapped cambelt on most modern engines means a destroyed engine.
• Coolant. Lifetime fill on many modern vans, but worth checking at the major service.
• AdBlue. Top up between services as needed; the dashboard will warn you.
• DPF (diesel particulate filter) regeneration. Not a service item per se, but worth understanding: short-trip use causes incomplete regens, which leads to expensive blockages. If your van is a fleet of one and you only do town miles, factor in an occasional motorway run.

Service intervals by manufacturer

Ford Transit and Transit Custom

The Ford Transit service schedule for both the full-size Transit and the smaller Transit Custom (now built on the same VW-Ford joint platform) is 18,000 miles or 12 months, whichever comes first. That is the standard for diesel and EcoBlue variants in the UK.

Some older Transit variants ran on a 20,000-mile / 1-year schedule, and US-market Transits run a much shorter 5,000-mile oil change cycle that has nothing to do with the UK schedule. Always check the service indicator and the handbook for the specific model year.

Cambelt change is typically at 144,000 miles or 10 years on the EcoBlue 2.0 diesel, but Ford has issued varying guidance over the years. Worth confirming against your specific engine code.

Mercedes Sprinter

The Sprinter service interval uses an alternating Service A / Service B pattern, managed by the ASSYST (Active Service System) computer that monitors driving conditions and tells you when each is due.

• Service A. First service at around 10,000 miles or 12 months. Subsequent Service A intervals are typically every 20,000 miles. Includes oil and oil filter change, fluid top-ups, multi-point inspection.
• Service B. First Service B around 20,000 miles, then alternating with Service A every 20,000 miles afterwards. Includes everything in Service A, plus brake fluid renewal and cabin/pollen filter.

In practice, a Sprinter on motorway miles will see a service alert roughly every 12 to 18 months. A van doing local delivery work will see them more frequently, because ASSYST factors in cold starts, idling, and short trips.

Service A is roughly £250 to £350 at a Mercedes specialist, Service B £400 to £600. Main dealers are higher.

Volkswagen Transporter and Crafter

VW vans (Transporter and Crafter) offer two service regimes, set in the dashboard menu when the van is new and changeable at any service:

• Fixed Service. Every 12,000 miles or 12 months, whichever comes first.
• Flexible (Longlife) Service. Up to 18,000 miles or 24 months, with the exact interval calculated by oil-condition sensors based on how the van is driven.

VW's own guidance: choose Flexible if you drive more than 25 miles per day on average, mostly long steady journeys, and avoid stop-start traffic. Choose Fixed if you do under 10,000 miles a year, lots of short trips, urban delivery work, or any towing.

The Flexible regime sounds cheaper (fewer services per year) but in stop-start use the sensors will pull the interval back so far that you can end up servicing the van more often than the Fixed schedule would have demanded. For most UK trade users, Fixed is the right call.

Vauxhall Vivaro, Peugeot Expert, Citroën Dispatch (Stellantis medium vans)

These three are the same van under different badges, built on the Stellantis EMP2 platform. The published intervals differ slightly between the Vauxhall and the PSA-badged versions:

• Vauxhall Vivaro (2019 onwards). 30,000 miles or 2 years.
• Peugeot Expert and Citroën Dispatch. 25,000 miles or 2 years.
• Toyota Proace and Fiat Scudo. Same platform, broadly the same intervals.

These are some of the longest published intervals on the UK van market. The catch: the 2-year time limit is firm, and most operators on these vans benefit from a mid-cycle oil and filter change anyway, especially in stop-start use. Many independent garages will recommend an interim oil change at the 12-month mark for vans that are working hard.

Renault Master, Nissan Interstar, Vauxhall Movano

The Renault Master and its rebadged stablemates (Nissan Interstar, formerly NV400, and Vauxhall Movano on the Renault platform) all run on a 25,000-mile or 2-year service interval, whichever comes first.

As with the Stellantis vans, that 2-year figure is generous on paper but wide enough that an annual oil change on heavily worked vans is a sensible insurance policy.

Iveco Daily

A common gap in most "best van" guides: Iveco Daily intervals run at 30,000 miles or 24 months for current diesel models, with the time figure usually being the trigger for UK trade users.

Light commercials (Caddy, Berlingo, Combo, Partner, Connect, Doblo)

Smaller car-derived vans typically follow their parent car's intervals: most are on a 12,000-mile / 12-month or 18,000-mile / 24-month cycle depending on whether the model offers a flexible regime. Always check the handbook for the specific year and engine.

Fixed vs variable: which to choose

If your van offers both regimes (most VWs and some Fords), the trade-off is straightforward.

Choose Fixed when: you do under 10,000 miles a year, most of those miles are urban or stop-start, you tow regularly, the van does idle a lot, or you want predictable annual service costs to budget against.

Choose Variable / Long-life when: you do over 15,000 miles a year, most of those are motorway or steady A-road miles, you rarely idle, and you can budget for a larger service bill less often.

The wrong choice in the wrong use case costs you more, not less. A long-life regime in stop-start delivery use will either be pulled back by the sensors (so you service as often as Fixed but pay more per service) or, if the warning is missed, will let the oil degrade past the point of protecting the engine.

What happens if you skip or stretch a service

Three things go wrong, in order of how soon you notice them:

Warranty void. Manufacturer warranties (typically 3 to 5 years on UK vans, with extended warranties from 100,000 to 150,000 miles) require a documented service history at the published intervals. Miss one and the warranty is at risk for any related claim. Some manufacturers void it entirely; others case-by-case.

Resale hit. A van with a full service history (FSH) sells for materially more than one without. The figure varies by age and model, but a missing service stamp on a 3-year-old Transit can knock £1,000 to £2,500 off the trade price. On a Sprinter or VW, often more.

Mechanical damage. This is the slow, expensive one. Old oil leads to turbo failure, timing chain stretch, and bearing wear. Old fuel filter leads to injector damage. Old brake fluid leads to brake fade and corrosion in the ABS unit. None of these show up immediately. All of them are far more expensive to fix than the service that would have prevented them.

If you do find yourself overdue, book the service now and ask the garage to flag any items that need closer monitoring. Do not chase the original schedule by stretching the next interval to compensate; reset your clock from the date of the catch-up service.

How to never miss a van service

The fleets that always service on time do three things:

Track both date and mileage. A spreadsheet with a "next service due" column showing the lower of (last service date + 12 months) and (last service mileage + interval miles). Whichever resets first becomes the next deadline.

Set reminders 4 weeks out. Long enough to book a slot at your preferred garage without paying a premium for a same-week appointment. Diary alerts work; van management apps work better because they pull current mileage automatically and recalculate the date as the van is used.

Build it into the weekly walkaround. A daily walkaround check already covers fluids, lights, and tyres. Add "is a service due in the next month?" to the same routine and you will never be surprised.

Service management tools automate the tracking by combining the published interval for your specific van with live mileage tracking, so the next-service-due date moves as the van moves. For multi-vehicle fleets, this is the only way to keep on top of service intervals that all run on different clocks.

The bottom line

Van service intervals are simple in principle and easy to lose track of in practice. Almost every modern van wants a service every 12 to 24 months or 12,000 to 30,000 miles, whichever comes first. The exact number depends on the van, the engine, and the regime you have selected.

Look up your van's interval in the handbook. Set a reminder against both the date and the mileage. Book the service when the earlier of the two is within 4 weeks. Do that consistently and you will keep the warranty intact, the resale value strong, and the surprise repair bills off your year-end accounts.
