What does it cost to clean a DPF in the UK?
DPF cleaning prices in 2026 range from £15 (DIY additive) to £450 (workshop off-car deep clean for a large van DPF). Here is the full breakdown.
By method
- Fuel-tank additive (DIY): £15-£30. Mild cases only.
- Forced active regeneration at a garage: £90-£140 + diagnostic.
- Mobile on-car chemical clean: £180-£280 per vehicle.
- Workshop off-car ultrasonic + thermal clean: £150-£300 for cars, £300-£450 for vans and 4x4s.
By vehicle type
- Small/medium car (1.5-2.0L diesel): £150-£250 off-car, £180-£220 mobile.
- Large car / SUV / 4×4 (2.0-3.0L): £200-£300 off-car, £220-£280 mobile.
- Light commercial van (Transit, Sprinter, Vivaro): £250-£400 off-car.
- Heavy commercial / motorhome: £350-£450 off-car.
Why prices vary
- Filter physical size: van and 4×4 DPFs hold 2-3x the soot/ash of a car DPF.
- Mounting: some DPFs are integrated with the turbo or downpipe, increasing removal labour.
- Contamination type: oil-soaked filters need extra cleaning cycles.
- Mobile vs workshop: mobile saves no-removal labour but uses chemical solvent.
How that compares to DPF replacement
A replacement OEM DPF costs £800-£2,500 for the part alone, plus £200-£400 labour. Aftermarket replacements are cheaper (£300-£800) but quality varies and warranty is often limited. Cleaning is the right first step for any filter where the ceramic substrate is intact.
