Warning light on a vehicle?

Do not wait for limp mode. A DPF warning light means a blockage the engine can’t clear on its own. Left alone, it leads to limp mode or a vehicle off the road – a harder, costlier fix and lost working days. Call us as soon as it appears.

 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is Google. 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!

 Trustindex verifies that the original source of the review is Google. 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.

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 maintenance cleaning

Mobile on-site DPF & CAT cleaning

We come to your depot, yard or customer site. Our industrial clean restores the DPF without removing it, with diagnostics before and after so you know the vehicle is fit to go back to work. For larger sites we bring a full team to clear the whole depot in one visit.

One-off from £250 (exc VAT) including collection and delivery; Trade Account prices from £210 (exc VAT).

Planned maintenance cleaning

We recommend a professional deep-clean for cars around every 20,000 miles or 24 months. LCVs usually need cleaning more often, especially on urban work. For HGVs we recommend a clean at 100,000 miles, then every 50,000 miles or 2,000 hours. Where you have telematics, we can clean on condition rather than the calendar.

FAQs

Fleet and trade FAQs

Do you cover the whole UK?

Yes. We run a nationwide mobile service and can usually be with you next day, sometimes even same-day. Call the business hotline for anything needed within the next three days.

Can you do several vehicles in one visit?

Yes. One engineer, or a full team for larger sites, can work through several vehicles in a single visit – one mobilisation and one purchase order, with every vehicle back on cycle at once.

Which vehicles do you cover?

Cars, LCVs, HGVs, buses and coaches, plant and NRMM, agricultural and marine equipment – diesel DPFs and petrol particulate filters (GPF/OPF), plus catalytic converters.

Are your engineers accredited?

Every engineer is our own – never subcontracted – and we are accredited to SafeContractor, SSIP, ISO 9001 and ISO 14001, so DPF work fits inside your existing compliance and site-access requirements.

How does invoicing work?

Account customers get 30-day terms and consolidated invoicing, with tiered pricing that reflects your fleet size, depot footprint and how often you need us.

What if a DPF can’t be cleaned?

We tell you straight. Where on-vehicle cleaning isn’t suitable – for example a non-running vehicle – our off-car factory clean is the next step. If a unit is beyond cleaning, we can supply a replacement through our online shop. Clean first where suitable. Replace only where necessary.

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 restore DPFs to full working order instead.

How often should fleet vehicles be cleaned?

We recommend around every 20,000 miles or 24 months for cars, more often for LCVs on urban or stop-start work, and for HGVs a first clean at 100,000 miles, then every 50,000 miles or 2,000 hours. Condition-based cleaning is ideal where you have telematics.
