Key price driver
Costs rise sharply if the DPF is severely blocked or needs off-car cleaning
A diesel particulate filter (DPF) is designed to trap soot and reduce harmful exhaust emissions from diesel vehicles. Over time, soot can build up and the filter may need cleaning to prevent blockages, warning lights, and loss of power.
The cost of DPF cleaning varies depending on whether the filter is maintained regularly or has become heavily blocked.
Here, you'll discover how much DPF cleaning costs in 2026, what affects the price, how long it takes, and when replacement may be unavoidable.
Diesel particulate filters (DPFs) became mandatory on diesel vehicles in 2009 as part of legislation to lower carbon emissions.

DPF cleaning (also known as flushing) is a relatively straightforward job if it’s part of regular maintenance.
If there isn’t already a fault, serious issue, or blockage, you can expect to pay around £85 (+VAT) for DPF cleaning.
Ignoring early DPF warning signs can turn an £85 clean into a four-figure replacement. Acting early is usually the cheapest option.

What affects DPF cleaning costs?
Several factors explain why DPF cleaning quotes can vary:
Level of blockage – light soot build-up is cheaper to clean than severe clogs
Cleaning method required – off-car or chemical cleaning costs more
Vehicle make and model – premium or complex systems may take longer
Mobile vs garage service – mobile services may include a callout fee of around £65
Location – labour rates are generally higher in London and the South East
Understanding these factors can help avoid unexpected costs.
