The short answer
Fixing a car scratch in the UK ranges from a small two-figure sum for a light scratch polished out of the clear coat, to a few hundred pounds or more when the scratch goes through the paint to the primer or metal and the panel needs respraying. The deciding factor is depth. A surface scratch sitting only in the lacquer (clear coat) can often be machine-polished out with no paint at all. A scratch that has cut through the colour base coat to the primer or bare metal needs filling, priming, colour-matching and a localised respray, which is far more involved. Length, location and whether several panels are affected all push the cost up.
How much a scratch costs to repair depends almost entirely on how deep it is. The sections below explain the layers of car paint and which repair each scratch needs.

Why depth decides the price
Modern car paint is built in layers: primer on the metal, then the colour base coat, then a clear lacquer (clear coat) on top. How deep a scratch goes through these layers determines the repair. The quick test is to run a fingernail across the scratch — if your nail does not catch, it is usually only in the lacquer and can often be polished out. If it catches, the scratch has cut into the colour or deeper and needs paint.
A light clear-coat scratch is the least expensive to fix because a detailer or bodyshop can machine-polish it out, removing a fine layer of lacquer to level the surface. A scratch into the colour coat needs that colour replaced and re-lacquered locally. A scratch through to the primer or bare metal — a deep key scratch, for example — needs filling, priming, colour-matched base coat, lacquer and blending, which is essentially a small respray and the dearest option. Bare metal also needs sealing promptly to stop rust starting.
| Scratch depth | Repair needed | Typical UK range |
|---|---|---|
| Clear coat only | Machine polish / buff | Low two figures |
| Into colour base coat | Localised respray of area | Low to mid three figures |
| Through to primer | Fill, prime, paint, blend | Mid three figures |
| Through to bare metal | Full localised respray | Several hundred pounds+ |

Touch-up pens and DIY versus a bodyshop
For a tiny stone chip or hairline scratch, a colour-matched touch-up pen or stick in the correct paint code is a low-cost way to seal bare metal and make the mark less visible. It rarely gives an invisible repair, though — the patch of paint sits slightly proud and the colour seldom matches perfectly, especially on metallic finishes. DIY touch-up is better thought of as protection against rust and a cosmetic improvement, not a true repair.
For anything you want to look right, a bodyshop's localised respray is the proper fix. The technician sands the scratch back, fills if needed, primes, sprays the colour matched to the paint code from the VIN plate or door-shut sticker, lacquers, and blends the new paint into the surrounding panel so there is no hard edge or colour step. Blending is the skill that makes a repair invisible, and it is why a professional scratch repair costs more than a pen but looks far better and lasts.
Scuffs, scrapes and the grey area in between
Not every mark is a clean single scratch. Many real-world cases are scuffs and scrapes — a brush against a gatepost, a trolley drag, or another car's paint transferred onto yours. A paint transfer, where a streak of the other object's colour is left on your panel but your own paint is intact underneath, is often the easiest and least costly to deal with: it can frequently be polished or compounded off without any repainting at all, because the damage is sitting on top of your lacquer rather than cut into it.
Where it gets less clear is a scuff that has marked the lacquer but not gone through it. Run a fingernail across it: if it does not catch, machine polishing will usually lift it; if it catches, some colour has been removed and a localised respray is the honest fix. This middle ground is exactly where a smart-repair specialist earns their keep, judging whether a mark will polish out or needs a small paint repair. A quick assessment saves money here, because paying for a respray on a scuff that would have polished out is wasted, and trying to polish away a scuff that has cut into the colour just thins the surrounding lacquer without fixing the mark.
What else changes the cost
Beyond depth, the length of the scratch and how many panels it crosses matter. A short scratch on one door is cheaper than a long key scratch running across a door, wing and bumper, because each panel that needs paint adds prep, masking and blending time. Colour plays a part too — solid colours are easiest to match, while metallics, pearls and tri-coats are harder and may need the colour spraying out on a test card to get the match right.
The position of the scratch on the panel also affects how the repair is done. A scratch in the middle of a large, flat panel can be tricky because the painter has to blend the new paint out into a wide area so the repair fades invisibly into the old colour; a scratch near a natural break — a body line, an edge or a swage line — lets the painter end the blend at that line, which is cleaner. This is why two scratches of the same depth can be quoted differently depending on where they sit.
As with dents, paying cash for a single scratch is usually cheaper than an insurance claim, because the repair often costs less than a typical policy excess and a claim can affect your no-claims discount. Smart-repair specialists, who do localised cosmetic repairs rather than full panel work, can be a cost-effective middle ground for scratches and scuffs that are too deep for polishing but do not need a whole panel resprayed. Getting the scratch looked at lets a repairer tell you which category it falls into before you commit.
Frequently asked questions
Can a deep scratch be polished out?
No. Polishing only works on scratches that sit within the clear lacquer — if your fingernail catches in the scratch, it has cut into the colour or deeper and needs filling and repainting, not just buffing. Trying to polish out a deep scratch only thins the surrounding lacquer without removing the mark.
Are touch-up pens worth using?
For tiny chips and hairline scratches they are worth it to seal bare metal against rust and reduce how visible the mark is. They rarely give an invisible result, though, because the paint sits slightly proud and the colour seldom matches exactly, especially on metallics. For a proper finish a localised respray is needed.
Why does a long scratch across several panels cost more?
Each panel that needs paint adds its own preparation, masking, spraying and blending time, so a scratch crossing a door, wing and bumper costs far more than the same scratch on a single door. Matching and blending the colour across multiple panels also takes longer to keep the repair invisible.
