Most blocked filters are clogged, not broken — a proper deep clean restores them and saves you £1,000+ vs a new DPF. We come to you, fixed price agreed first.
30 seconds — we'll call you straight back.
What you'd actually pay each way — and when replacement is genuinely the right call
A genuine replacement filter for most cars and vans runs £700–£2,500 for the part alone, before fitting and VAT. On many diesels you're looking at £1,000 to £3,000+ all in, and you're often replacing a filter that was never broken — just blocked. It's the priciest fix on the table and, nine times out of ten, the unnecessary one.
Our Premier DPF Clean removes up to 98% of soot and ash with a full pre and post diagnostic, engine carbon clean included, and a 3-month warranty against re-blocking. Same or next-day, at your home or work, no garage booking and no courtesy-car juggling. The maths is simple: a clean typically costs a fifth of a replacement and lasts the life of the filter.
We won't pretend a clean fixes everything. If the ceramic substrate inside is cracked or has melted from a runaway regeneration, cleaning can't rebuild it — that filter needs replacing, and we'll show you exactly why on the diagnostic. This is the rare exception, not the rule. Honest testing is the only way to know which camp you're in, and that's exactly what we do first.
These symptoms point to a blocked filter, not a broken one. A clean usually fixes them.
A blocked filter is the textbook case for cleaning, not replacement. Soot and ash build up over short journeys and town driving; clear them and the filter flows like new. Being told it's blocked is a reason to clean it, not bin it.
Reduced power and a glowing DPF light are the car protecting itself from a clogged filter — not proof the filter has failed. Once a deep clean restores flow and we confirm it with live data, these symptoms clear without a single new part.
If your DPF can no longer complete its own regeneration cycle, it's simply too loaded to burn off. That's a cleaning job. Replacing the filter to fix a regen problem is paying thousands to solve something a clean handles for a few hundred.
Every job starts with backpressure and live-data testing, and ends with the same tests repeated. You see the before and after for yourself — so you know the clean worked and you didn't need the replacement you were quoted for.

Get my free quoteWhen a dashboard light comes on, plenty of garages reach straight for the parts catalogue — a new DPF is a high-value job and the easy answer. But a filter that's clogged with soot and ash isn't a failed filter; it's a dirty one. Unless the internal substrate is physically cracked or melted (genuinely rare), the same filter that's blocked today can be cleaned back to near-new flow and bolted straight back on.
Our whole approach here is honesty over upselling. We run a proper diagnostic with live backpressure testing first, so the recommendation is based on numbers, not a hunch. If a clean will fix it — and it almost always will — we'll save you four figures. If your filter is truly beyond saving, we'll tell you that too, plainly, so you don't waste money cleaning something that can't be recovered.
Whatever you drive, we've almost certainly cleaned one — cars and vans welcome.
DPF and engine carbon cleaning is the whole job — not a sideline.

"Very pleased with the work that was carried out, engineer was very professional and explained the process throughout. I would highly recommend EngiClean."
"Would definitely recommend this company. They spent time on my Mercedes and the Manager came out on his day off to help. Couldn't have been more helpful to a stressful situation."
A deeper clean for engines that have earned it — a £50 +VAT upgrade to the Premier DPF Clean.
On engines past 120,000 miles, soot and ash sit deeper in the filter. Our 2-stage on-vehicle clean is built for exactly that — a deeper DPF clean carried out at your driveway or work, with the engine carbon clean and full diagnostics included.
We'll tell you from your reg whether your vehicle needs it. Like every price we quote: agreed up front, before anything is booked.
Almost always, and not by a small margin. A new DPF fitted typically costs £1,000 to £3,000+, while our Premier DPF Clean starts from £280 +VAT and is done at your door. As long as the filter isn't physically damaged inside, a clean restores the same part for roughly a fifth of replacement cost — which is why we test first rather than assume.
The filter alone is usually £700–£2,500 depending on make and model, with premium and larger vehicles at the top end. Add fitting and VAT and most replacements land between £1,000 and £3,000+. That's exactly why it's worth getting an honest clean-or-replace verdict before committing to that spend.
Only when the internal ceramic substrate is physically cracked or has melted — usually from a regeneration that ran out of control or the filter being driven on while severely overloaded. This is rare. If we find it, we'll show you the evidence on the diagnostic and won't charge you to clean something that can't be recovered.
Yes — that's precisely what this service is for. Send us the quote or just book the Diagnostic Health Check (from £120 +VAT). We test backpressure and live data to confirm whether the filter is blocked (cleanable) or damaged (replace). Most of the time we clean the same filter the garage wanted to bin.
A properly cleaned filter that wasn't damaged behaves like a fresh one — full flow restored, soot and ash removed. How long it stays clear depends mostly on how you drive afterwards. We include a 3-month warranty against re-blocking and give you simple driving advice to keep it clear for the long haul.
Our Premier DPF Clean is a chemical deep clean that lifts up to 98% of soot and ash from inside the filter, paired with a full pre and post diagnostic so we can prove the result. Stubborn or heavily-loaded filters can be removed and deep-cleaned off-car on our mobile rig, then refitted — all done at your location.
When it's the honest answer, yes. If the substrate is cracked or melted, a clean is a waste of your money and we'll say so. We'd rather lose a cleaning job than send you away with a filter that won't recover — that honesty is why people send us their replacement quotes in the first place.
Found it cheaper? We'll beat any genuine like-for-like quote. We also agree the fixed price before we start, so there are no surprises once we're at your door — just the saving against replacing a filter that probably didn't need replacing.
A replacement quote is a starting point, not a verdict. Before you spend four figures on a new DPF, let us test the one you've got — at your home, work or the roadside, anywhere across Scotland and the North East, same or next day. If a clean will fix it, you keep over £1,000 in your pocket. If it genuinely needs replacing, you'll get the honest truth and the proof to back it. Call 0333 455 9058 or send us your quote and we'll tell you straight.
