Refurbishing an alloy wheel in the UK usually costs roughly £50–£120 per wheel, so a full set of four commonly lands somewhere around £200–£480 before extras. A diamond-cut finish typically costs more than a painted or powder-coat refurbishment, because it needs specialist lathe work and curing. Timing depends on the method: a mobile smart repair can be done in a few hours on cosmetic damage, while a full off-car powder-coat or diamond-cut refurbishment in a workshop more often takes one to three working days to allow proper curing. Cosmetic kerb scuffs are usually repairable, but a buckled or cracked wheel is a safety matter and should be assessed by a specialist, who may advise replacement rather than repair. The honest answer is always a range, because it depends on your wheel size, finish and the damage.
Most alloy wheel guidance is published by firms doing the work, so the numbers tend to be optimistic and the safety limits glossed over. The pages below give honest cost ranges, compare the finishes fairly, explain how long the work takes and when a damaged wheel can or cannot safely be repaired — before you take a single quote.
