Price guide · 2026
Most London mileage correction jobs fall between about £80 and £350 in 2026, depending on the vehicle and how many modules hold a mileage value. Straightforward cluster synchronisation sits at the lower end; premium vehicles needing multi-module programming reach £200 to £500 or more.

These are the ranges we publish, and they line up with what the London market charges for the same work. They are ranges rather than fixed prices for a reason: the job is not the same job on every car.
| Type of work | Typical range | What is involved |
|---|---|---|
| Basic mileage synchronisation | £80 – £150 | Diagnostics, mileage verification, module synchronisation, testing |
| Instrument cluster programming | £120 – £250 | Coding and programming a replacement cluster to the vehicle |
| ECU and multi-module synchronisation | £150 – £350 | ECU diagnostics, data verification, programming across modules |
| Premium and performance vehicles | £200 – £500+ | BMW, Mercedes-Benz, Audi, Porsche, Jaguar, Land Rover architectures |
| Mobile recalibration at your address | £120 – £300 | On-site diagnostics plus travel, depending on location and vehicle |
Because on a modern vehicle the mileage is not stored in one place. Manufacturers deliberately mirror the value across several modules so that a single tampered unit shows up as an inconsistency. A proper correction has to read and rewrite every one of those stores.
On a fifteen-year-old hatchback that might mean the cluster and nothing else. On a recent BMW it can mean the cluster, the CAS or FEM module, the engine ECU and the key transponders. Same customer request, four times the work, and equipment and manufacturer data that cost considerably more to license.
The second driver is access. Most jobs are done through the diagnostic port. Some need the cluster removing and working on directly, which turns a plug-in visit into a bench job. That is a genuine step change in labour, and any honest quote will flag it as a possibility before starting rather than after.
Significantly. Analogue clusters with a simple stored counter are the cheapest work there is. Fully digital dashboards store more, verify more and often check what other modules believe before displaying anything. Hybrid and electric vehicles add another layer, because the drivetrain controllers keep their own distance records for battery and service management.
None of that is an upsell. It is the reason two quotes for the same-sounding job can differ by two hundred pounds, and the reason we ask for the exact model and year on the phone rather than quoting from the make alone.
Less than most people expect inside the North Circular, more once you are heading out to the county boundaries. Travel is a real cost and we quote it inside the job figure rather than adding it at the end.
From our Walthamstow base, local E17 work and the surrounding East London postcodes carry very little travel weight. North London is similar. Essex and Kent runs carry more, which is why our Essex cost guide quotes slightly different figures for the same work.
If you have more than one vehicle at the same address, say so when you call. Spreading one journey across three cars changes the per-vehicle figure more than any other single factor.
Ask what the quote covers before you agree to it. A complete job includes all six of these, and a quote that omits any of them is not cheaper, it is smaller.
The written record is the one people skip past. It is also the only part of the job that still has value in two years time, when a buyer asks why the MOT history has a step in it.
Ask both of them the same three questions and the cheaper one often stops being the cheaper one.
A quote that is a third cheaper than everyone else is usually cheaper because it is doing a third of the job.
When nobody asks you why. A technician who takes a figure from you over the phone and quotes forty pounds without asking what was replaced, what the MOT history shows or what the other modules hold is not doing the diagnostic work that makes the correction defensible. They are typing a number into a cluster.
That matters beyond the technical result. Under the Consumer Protection from Unfair Trading Regulations 2008 it is the use of a false reading that creates liability, and the paperwork proving why a correction was made is what keeps a legitimate job on the right side of that line. A cheap job with no record leaves you holding the awkward end of that conversation.
If you want the background, our guide to whether mileage correction is legal in the UK sets out where the line actually sits.
We can give you a firm quote once we know the make, model, year and what was replaced or what fault occurred. Quoting from the make alone would be guessing, and the guess would have to be padded.
No separate fee bolted on afterwards. Travel is part of the figure we quote before we set off, so the number you agree is the number you pay.
Because the mileage is mirrored across more modules, the manufacturer data and equipment cost more to license, and the job takes longer. It is genuinely more work rather than a brand surcharge.
We try hard to establish that on the phone rather than after travelling. If the honest answer is that the evidence does not support a correction, we will tell you before anyone spends money.
Slightly, because there is no travel in the quote. For most London customers the difference is small enough that the time saved by a mobile visit is worth more.
Call 07837 078155 with the make, model, year and what changed on the dashboard. The quote is free and it is the figure for the job, travel included.
