    Planned or condition-based

    Where telematics or OBD data is available, we clean on condition – before a blockage turns into a breakdown. Otherwise we build a schedule from make and model, duty cycle and the most recent diagnostics.

    Plan your schedule

    Priority when it goes wrong

    Even the best plan can’t stop every failure. When a vehicle drops into limp mode, contract accounts get priority response, so one fault doesn’t become a lost week.

    The technician arrived and discussed my car and possible outcomes of the test and clean with me for several minutes before starting work. Once done, there was a thorough discussion about ongoing care (and further advice about my upcoming car purchase) followed by a lengthy report. Knowledgeable, straightforward, professional.

    Ethan not only cleaned the DPF but also went to great lengths to identify some other issues with my car - two holes in the exhaust and a faulty accelerator cable which are being fixed next week. He was very polite, friendly, efficient and went the extra mile to identify the problems and give me good advice. This is particularly important for me as a disabled driver who drives from my wheelchair. Thanks Ethan!

    Had mine sorted two days ago. The guys name was Egor. Was ready at my home waiting for me after work so bonus points for being on time All sorted he even stayed extra 30 mins to make sure everything was correct. Clearly takes pride in his work. Dpf light still off. Would definitely recommend based on my experience. Thankyou.

    Recommended intervals

    How often should fleet DPFs be cleaned?

    CarsAround every 20,000 miles or 24 months, depending on duty pattern
    Vans & LCVsMore often than cars – especially on short urban journeys, multi-drop rounds and idling
    HGVsA first clean at 100,000 miles, then every 50,000 miles or 2,000 engine hours
    Buses & coachesSet by engine hours and route profile – stop-start urban routes need more frequent cleans
    Plant & NRMMSet by engine hours, ideally aligned with seasonal downtime or planned service windows
    Condition-basedWhere telematics are available, clean on soot load and regeneration frequency rather than the calendar

    Mileage alone isn’t enough
    Engine hours, load, idling time, regeneration frequency and operating environment all affect how fast soot and ash build up. We use data from more than 36,000 real-world DPF cases to help set the right schedule for each vehicle.

    Plan your schedule
    Preventive cleaning for predictable cost

    Regular cleaning gives the biggest saving

    Unplanned DPF failures take vehicles off the road at the worst moment, with delays for investigation, cleaning or replacement parts. Planned cleaning usually pays for itself very quickly.

    Unplanned DPF failures mean:

    • Vehicles off the road at short notice
    • Missed rounds and rearranged schedules
    • Limp mode and recovery costs
    • Workshop delays waiting for parts
    • Expensive replacement DPFs
    • Knock-on damage to related engine parts

    Planned cleaning gives you:

    • Fewer DPF failures in service
    • Work planned around your schedules
    • DPFs cleaned before blockages become severe
    • Fewer excessive regenerations
    • Better fuel economy from a clean DPF system
    • Fewer replacements needed
    Do not wait for limp mode. Clean first where suitable. Replace only where necessary. Speak to our team
    What 36,135 DPF jobs tell us

    Vans block younger than you think

    We analysed 36,135 DPF cases from November 2024 to July 2026. For commercial vehicles the message is clear: low age and low mileage are no protection.

    8.4 yrsTypical age of a van with a blocked DPF – around 3 years younger than cars (11.3 years)
    46%of the commercial vehicles we treated were under 8 years old
    1 in 7commercial vehicles showed no warning light at all before the problem
    27,694median miles at which low-use vans (under 5,000 miles a year) blocked
    Short trips, stop-start rounds and idling are the risk – exactly the work most fleets do. Planned cleaning costs far less than a vehicle off the road. Plan your cleaning schedule

    Every vehicle, every duty cycle

    The right clean. The right advice. The right next step.

    Full diagnostics and warrantied cleaning as standard

    Every visit starts with a visual inspection and full diagnostics to confirm cleaning is the right solution. If damage makes cleaning impossible, we tell you straight away and can source a replacement. After the industrial clean and regeneration, we run diagnostics again to confirm the DPF is working within limits – and email both reports with our engineer’s recommendations.

    Root cause checked: sensors, EGR, injectors, turbo, thermostat

    Off-road and Stage V equipment

    Harsh conditions make regeneration unpredictable on plant, agricultural and construction machinery – so planned inspection and cleaning matter even more. We advise aligning DPF maintenance with seasonal downtime or planned service windows, to avoid disruption at peak times. We clean on site with our mobile units, or units can be removed and sent to us for rapid factory cleaning.

    Compliance and duty cycles

    Regular cleaning supports Euro VI emissions compliance for HGVs and Stage V compliance for non-road mobile machinery. Because engine hours, load, idling and environment all change how quickly a DPF fills, we recommend regular diagnostic checks rather than relying on mileage alone.

    FAQs

    Fleet maintenance FAQs

    How often should our vehicles be cleaned?
    As a guide: cars around every 20,000 miles or 24 months; vans and LCVs more often, especially on urban work; HGVs at 100,000 miles, then every 50,000 miles or 2,000 engine hours; plant and NRMM by engine hours. We’ll recommend a schedule for each vehicle based on its duty cycle and diagnostics.
    What is condition-based cleaning?
    Where telematics or OBD data is available, we clean when soot load and regeneration frequency show it’s needed, rather than on a fixed date. It catches problems early and avoids unnecessary cleans.
    Can you work around our shifts?
    Yes. Visits are booked around your operation, and one engineer – or a full team for larger sites – can work through several vehicles in a single visit.
    How long does a clean take?
    Most DPF cleans take around 2 hours, wherever the vehicle is, including diagnostics before and after.
    What records do we get?
    Before-and-after diagnostic reports for every vehicle, plus any recommendations from our engineer, emailed to you after each visit. Every clean has a 30-day warranty.
    What if a DPF can’t be cleaned?
    We tell you straight away. Where on-vehicle cleaning isn’t suitable, our off-car factory clean is the next step. If a unit is beyond cleaning, we can supply a replacement. Clean first where suitable. Replace only where necessary.
    Do you clean catalytic converters too?
    Yes – we clean CATs as well as DPFs, on cars, vans, HGVs and plant.
    Will you remove a DPF?
    No. Driving a vehicle with its DPF removed is illegal, it will fail its MOT, and it can lead to heavy fines. We keep DPFs working properly instead.
