The short answer
Alloy wheel refurbishment in the UK typically costs from a low-to-mid three-figure sum per wheel for a standard painted or powder-coated finish, with a full set usually working out cheaper per wheel than singles. Diamond-cut finishes cost more because they need a specialist lathe to re-cut the face, and not every refurbisher offers them. A standard refurb strips the old finish, repairs kerb damage and corrosion, then recoats and lacquers the wheel. Price depends on wheel size, the finish (painted, powder-coated or diamond-cut), the severity of kerb or corrosion damage, and whether the wheel is buckled or cracked. Mobile kerb-scuff repairs are cheaper than a full off-car refurbishment but are a cosmetic touch-up, not a full restoration.
Alloy refurbishment is priced per wheel, but the finish type and damage make a big difference. The sections below break down the cost by finish and condition.

What a refurbishment involves and what it costs
A full refurbishment is more than a respray. The wheel is stripped back to bare alloy — by chemical dipping or media blasting — so any kerb damage and corrosion can be repaired on a clean surface. It is then primed, coated (painted or powder-coated) in the chosen colour and finish, and sealed with lacquer. Powder-coating, where a dry powder is applied and baked on, gives a tough, even finish and is popular for its durability.
The cost is usually quoted per wheel, and a full set of four is generally cheaper per wheel than doing one or two, because the setup and curing time is shared. Larger-diameter wheels and more complex multi-spoke designs cost more, as do wheels with heavy corrosion (the 'white worm' of alloy oxidation), buckles or cracks that need extra repair before refinishing. A simple recolour of sound wheels is at the lower end; a full restoration of corroded, kerbed wheels is higher.
| Finish / job | Typical UK range | Notes |
|---|---|---|
| Painted / powder-coated (per wheel) | Low to mid three figures | Standard refurbishment |
| Full set of four | Lower per-wheel rate | Shared setup and curing |
| Diamond-cut (per wheel) | Higher than painted | Needs a CNC lathe |
| Mobile kerb-scuff repair | Lowest | Cosmetic touch-up only |

Diamond-cut versus painted finishes
Two main finishes dominate, and they cost differently. A painted or powder-coated wheel is coated all over in colour and lacquer — durable, repeatable, and offered by almost every refurbisher. A diamond-cut wheel has its face machined on a CNC lathe to expose bright bare metal, which is then sealed with lacquer to give the distinctive shiny, machined look found on many modern factory wheels.
Diamond-cut costs more for two reasons: it needs the specialist lathe and the skill to re-cut the face accurately, and each re-cut removes a thin layer of metal, so a wheel can only be diamond-cut a limited number of times before too much material is lost. Diamond-cut finishes are also more prone to lacquer peel and corrosion if the seal is breached, because bare metal sits just under the lacquer. Many owners choose to convert a tired diamond-cut wheel to a painted or powder-coated finish instead, which is cheaper, more durable and can be repeated indefinitely.
On-car versus off-car refurbishment
There are two ways a refurbisher works, and they suit different jobs. Off-car (off-vehicle) refurbishment is the thorough route: the tyres are removed, the wheels are stripped right back, repaired, recoated and re-fitted with the tyres rebalanced. This allows the whole wheel, including the inner rim and barrel, to be refinished and is the standard for a full restoration of corroded or heavily kerbed wheels. It takes longer and costs more because of the tyre removal and refitting.
On-car or mobile refurbishment refinishes the face of the wheel with the tyre still on, masking the tyre and the brakes. It is quicker and cheaper and ideal for cosmetic kerb scuffs and tidying the wheel face, but it cannot properly address corrosion on the inner rim or behind the tyre bead, and the finish around the rim edge is not as complete as an off-car strip. For a wheel that is simply scuffed on the face, on-car is good value; for one that is corroding or needs a finish change such as diamond-cut, off-car is the proper choice. Tyre condition matters too — if a tyre is worn, doing an off-car refurb at the same time as a tyre change saves paying for the removal twice.
Scuff repairs, buckles and when not to refurbish
Not every wheel needs a full refurb. A single kerb scuff on the rim edge can be smart-repaired by a mobile technician — sanded, filled, recoloured and lacquered on the affected area only — which is much cheaper than stripping the whole wheel. This is a cosmetic fix that blends the damage rather than restoring the wheel completely, and it is ideal for minor edge scrapes.
Some damage goes beyond refinishing. A buckled wheel can sometimes be straightened, and minor cracks in certain wheels may be repairable by a specialist, but safety-critical damage — significant cracks, or buckles that cannot be trued — means the wheel should be replaced rather than refurbished, because a wheel that fails at speed is dangerous. A reputable refurbisher will refuse to cosmetically hide a crack. For most owners, though, the wheels are simply kerbed, corroded or faded, and a standard painted or powder-coated refurbishment restores them well for a sensible per-wheel price.
Frequently asked questions
Why does a diamond-cut finish cost more than a painted one?
Diamond-cut needs a specialist CNC lathe to machine the wheel face and the skill to re-cut it accurately, which painted and powder-coated finishes do not require. Each re-cut also removes a little metal, so the finish can only be redone a limited number of times, and it is more prone to lacquer peel if the seal is breached.
Is it cheaper to refurbish a full set or single wheels?
A full set of four is usually cheaper per wheel than doing one or two, because the stripping, coating and curing setup is shared across all the wheels. A single kerb-scuff smart repair on one wheel, however, is cheaper than a full refurbishment if only the rim edge is damaged.
Can a cracked or buckled alloy be refurbished?
A minor buckle can sometimes be straightened, but safety-critical damage like significant cracks means the wheel should be replaced, not refurbished. A reputable refurbisher will refuse to cosmetically cover a crack, because a wheel that fails at speed is dangerous. Refurbishment is for cosmetic kerb, corrosion and fading damage.
