The short answer
Repairing a car bumper in the UK typically costs from a low three-figure sum for a scuff or minor scrape smart-repaired and resprayed, up to several hundred pounds for a cracked bumper that needs plastic welding, filling and a full respray. Because most modern bumpers are flexible plastic, they are repaired differently from metal panels — they flex and crack rather than dent, and minor damage can often be filled, reshaped and resprayed rather than replaced. The cost depends on the type of damage (scuff, crack or split), how much of the bumper is affected, the paint colour, and whether parking sensors or trim need refitting. A badly split bumper, or one with broken mounting tabs, sometimes costs about the same to replace as to repair.
Bumpers are usually plastic, which changes how they are repaired and priced. The sections below cover the common types of damage and when repair makes more sense than replacement.

Scuffs, cracks and dents priced differently
The cost depends first on the type of damage. A scuff or light scrape that has only marked the paint and surface is the least costly — it can usually be sanded, filled if needed, and resprayed, often as a smart repair. A crack or split is more work: the plastic has to be cleaned, V-grooved and plastic-welded or bonded from behind to restore strength, then filled, sanded and resprayed on the face. A dent or distortion in plastic is often reshaped with heat before refinishing.
Because bumpers are plastic, they are repaired with flexible fillers and a flexible additive in the paint so the finish moves with the bumper rather than cracking. A whole-bumper respray is needed when the damage spans a large area or when blending into a colour (especially metallic) would be visible if only part of the bumper were painted. Off the car, the bumper can be sprayed evenly and refitted, which gives the most even finish.
| Damage type | Repair | Typical UK range |
|---|---|---|
| Light scuff / scrape | Sand, fill, smart respray | Low three figures |
| Deeper scrape / kerb damage | Fill and panel respray | Low to mid three figures |
| Cracked or split bumper | Plastic weld, fill, full respray | Mid three figures |
| Broken mounts / heavy damage | Often replacement instead | Several hundred pounds+ |

Repair versus replacement
For most cosmetic damage, repairing the existing bumper is cheaper than fitting a new one, because a replacement bumper has to be bought, painted to match and fitted — and a bare replacement still needs spraying in the right colour. Repair keeps the original part and only addresses the damaged area. So scuffs, light cracks and small splits are nearly always worth repairing.
Replacement starts to make sense when the bumper is badly split, shattered, or has broken mounting tabs and brackets that hold it to the car, because a bumper that will not clip back on securely is not safe to keep. Once the cost of welding and reinforcing a heavily damaged bumper approaches the cost of a painted replacement, replacing is the sensible call. Modern bumpers also carry parking sensors, cameras and washer jets, and on some cars radar units behind them — these add to both repair and replacement cost because they must be removed, refitted and, in some cases, recalibrated.
Front bumpers, rear bumpers and where damage happens
Where the damage sits changes the job. Front bumpers take the brunt of car-park nudges, kerb strikes when parking nose-in, and stone chipping at speed, and they often house the number plate, lower grille, fog lights and, increasingly, radar and camera sensors for cruise control and emergency braking. That makes a front-bumper repair more likely to involve removing and refitting electronics. Rear bumpers are most often scuffed by reversing into posts, walls and other cars, and they typically carry the reversing sensors and sometimes a reversing camera.
The corners and lower edges of any bumper are the most commonly damaged areas, because they stick out furthest and sit low to the ground. A scuff confined to one corner is often a quick localised repair, while damage that wraps around a corner onto the wing or spans the full width of the bumper pushes toward a complete respray for an even finish. Knowing exactly where the damage is, and what hardware sits behind it, is what lets a repairer judge whether it is a small smart repair or a bigger remove-and-respray job.
Colour matching and the cash-versus-claim question
Getting a bumper to match the rest of the car is its own challenge. Bumpers are moulded plastic, not metal, and even from the factory they can sit a fraction different in shade from the steel panels around them. A good bodyshop matches the paint code and, on metallics, sprays a test card and tints the colour to get it right, then blends into the adjacent wing or panel if needed so there is no visible step. A cheap respray that skips this can leave the bumper looking slightly off against the body.
As with other small repairs, paying cash for bumper damage is often cheaper than an insurance claim, because a scuff or scrape repair can cost less than a typical policy excess and a claim may affect your no-claims discount. Mobile smart-repair specialists can be good value for self-contained scuffs and small scrapes done at home or work, while a full bodyshop is better for cracks, splits or whole-bumper resprays. Repairing promptly is sensible because exposed cracks can spread and any bare areas can let water behind the paint.
Frequently asked questions
Can a cracked plastic bumper be repaired rather than replaced?
Usually yes. A cracked bumper can be cleaned, V-grooved and plastic-welded or bonded from behind to restore strength, then filled and resprayed on the face. Replacement only becomes the better option when the bumper is badly shattered or its mounting tabs are broken so it will not clip back on securely.
Why does a bumper need a flexible paint and filler?
Because the bumper is flexible plastic that moves and flexes in use, the repair uses a flexible filler and a flex additive in the paint so the finish bends with the bumper instead of cracking. A rigid filler or paint meant for metal would crack off a plastic bumper over time.
Do parking sensors make a bumper repair more expensive?
They can. Sensors, cameras, washer jets and any radar units must be removed before the bumper is repaired or replaced and refitted afterwards, and some systems need recalibrating. That adds labour and, occasionally, parts cost compared with a plain bumper.
