Lost power or MPG? We come to you — live before/after scan, at a fixed price agreed first. Mobile hydrogen carbon clean for the carbon baked on by short, cold journeys — Scotland & the North East.
30 seconds — we'll call you straight back.
A fixed-price, three-step clean built around the difference you can feel — carried out on your driveway, no workshop and no day off work.
Before we touch anything we plug in and read live data, then drive or rev the engine through its range so we can see the flat spots, the fuelling and how it idles. That baseline is your before reading — it's how we prove the gain at the end rather than just claiming it. If your symptoms point to something a decarbonise won't fix, we tell you straight before any money changes hands.
With the engine running, a controlled hydrogen-oxygen mix flows through the intake. Over roughly 45–90 minutes it breaks down and burns off the carbon coating the valves, injectors and combustion chambers — the exact deposits that are choking your throttle response and economy. Nothing comes apart, no parts are removed, and you stay with your car the whole time.
We run the scan again and show you the numbers next to the baseline, then hand it back for a drive. Most owners notice it on the road home: a willingness to pull that had quietly disappeared, a smoother idle at the lights and a lighter feel through the gears. We flag anything else worth keeping an eye on before we pack up.

Carbon rarely throws one dramatic fault — it shows up as a car that's slowly lost its edge. Recognise a few of these and a clean is usually worth it.
Clearing carbon off the inlet and injector tips lets the engine breathe and fuel cleanly again. The dead patch off the line and the heavy feeling at motorway speeds typically ease, so the car answers the pedal the way it did when it was younger.
Cleaner combustion means the engine does the same job with less effort, so many drivers see MPG climb back up — most noticeable on cars doing lots of short, cold, stop-start journeys around town, which are the worst offenders for building carbon in the first place.
When deposits build unevenly across the cylinders the engine shakes and hunts at a standstill. Burning that carbon off evens out how each cylinder fires, so the lumpy idle at the lights settles and the whole car feels less strained when it's just ticking over.
Because we scan before and after, the recovery isn't down to imagination — you see the readings move. It's the difference between hoping a service helped and watching the numbers confirm it before you've even pulled off the drive.
Car gone flat, thirsty or rough? A mobile hydrogen carbon clean on your driveway can have it pulling cleanly again — with a live before/after scan and the price agreed first.
Fixed prices confirmed before we start. Mobile service included.

Request a quoteMost of what dulls an engine is everyday driving: the school run, the city-centre crawl, the short commute that never lets it fully warm through. On those cool, low-load journeys the soot a modern engine recirculates bakes onto the inlet valves and injector tips instead of burning off. It creeps up so slowly you stop noticing — until the car feels heavy off the line, drinks more fuel than it used to, and shudders a little at idle. That flat, thirsty, slightly rough feeling is carbon, not age.
A hydrogen carbon clean tackles exactly that. A measured hydrogen-oxygen mix is fed through the air intake while the engine runs, lifting and burning off the softer deposits so the cylinders fill and fire cleanly again. Nothing is dismantled and no parts are removed — it is carried out entirely on your driveway in around 45–90 minutes, and we re-scan at the end so the change is something you can see on the screen, not just feel.

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.

"Great service today from Adam. Been having issues and Adam had this fixed and sorted within no time. Highly recommend, great service and fair prices!"
"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.
It comes down to how carboned the engine was to begin with. A car that's spent years on short, cold trips and has never been decarbonised usually shows the biggest jump — noticeably sharper throttle, a smoother idle and a useful lift in fuel economy. A newer, well-driven engine will see a more modest tidy-up. Because we scan before and after, you're not guessing: you see the readings move and you feel it on the drive home.
We read the engine's live data and run it through its range before we start, so we have a baseline of how it's fuelling and idling. After the hydrogen clean we run the same scan and show you the two side by side. It's there so the improvement is measured rather than just promised — you can see exactly what changed before you've left the driveway.
Very often, yes. Carbon build-up rarely triggers a dashboard light; it just slowly robs the engine of crispness, economy and smoothness. That gradual, light-free decline is the classic case for a decarbonise. We confirm it with the baseline scan first, and if your symptoms point to a worn part or a sensor fault instead, we'll tell you honestly rather than sell you a clean that won't help.
The gain holds for a good while — typically tens of thousands of miles — and how long depends mostly on how you drive afterwards. If your routine is still mostly short, cold town trips, carbon will rebuild faster than on a car that gets regular longer runs. Treating it as periodic maintenance, every 30,000–40,000 miles or so, keeps the engine on top of it rather than letting deposits creep back to where you feel them again.
Yes. Modern direct-injection petrols carbon up on the inlet valves just as diesels do, and they respond well to a decarbonise — owners often report a crisper throttle and steadier idle. We clean all makes and models, petrol and diesel, cars and vans. Tell us the make, model and rough mileage and we'll give you an honest view of how much you're likely to gain.
Absolutely — that's how a lot of customers book it. We work from a fully equipped mobile unit and only need normal access to the car with room to open the bonnet, whether that's your driveway, a work car park or the kerbside. You carry on with your day and we hand the car back done, usually inside 45–90 minutes.
Not on its own — this service restores engine performance, it doesn't clear a blocked diesel particulate filter or a DPF light. If your DPF warning is on or you're in limp mode that's a separate DPF clean, which we also offer and can do on the same visit. We diagnose first so you only pay for what your car actually needs.
Our Engine Carbon Clean starts from £150 +VAT and we agree the figure with you before any work begins — what we quote is what you pay, with nothing added once we're on your drive. Found it cheaper locally? We'll beat any genuine like-for-like quote. If you'd like a DPF clean on the same visit we'll set out a clear combined price up front too.
