Cycling Accident Compensation Calculator
Knocked off your bike? Estimate your injury band, bike damage and lost earnings claim
Last updated: July 2026
How cycling accident compensation is calculated
If you were knocked off your bike by a careless driver, your claim has two parts. General damages compensate the injury itself – the pain, suffering and loss of amenity – and are assessed against the bracket system in the Judicial College Guidelines, the reference courts and insurers use in England and Wales. Special damages repay every financial loss the crash caused: your bike, helmet and kit, lost earnings, physiotherapy, prescriptions, travel to appointments and care from family members. This calculator combines an estimated injury bracket with your actual losses, then applies any percentage deduction for shared fault, to give a realistic planning range before you speak to a solicitor. It is designed for cyclists hit by cars, vans, taxis and lorries, but the same principles apply to crashes caused by potholes (claims against the highway authority under the Highways Act 1980) and defective cycle parts (claims against the manufacturer or retailer).
Every figure it produces is an estimate. Real awards turn on medical evidence, your prognosis, your age and occupation, and negotiation between the parties – two cyclists with the same fracture can receive different sums. Treat the output as a sense-check, not a valuation.
Injury severity bands for cyclists (estimates)
Cyclists are unprotected, so the spread of injuries is wide – from road rash to life-changing head trauma. The bands below are rounded, indicative ranges based on Judicial College Guidelines (17th edition, 2024) brackets for injuries commonly suffered in cycling collisions. They cover the injury element only, before financial losses are added.
| Injury severity | Typical examples | Estimated range |
|---|---|---|
| Minor – full recovery within ~3 months | Cuts, bruising, road rash, minor sprains | £700 – £3,000 |
| Soft tissue – recovery up to ~2 years | Neck, back and shoulder strains, deep bruising | £3,000 – £9,600 |
| Simple fractures – good recovery | Clavicle (collarbone), wrist, forearm – the classic over-the-bars injuries | £6,000 – £23,000 |
| Serious limb injuries – incomplete recovery | Complex leg or arm fractures, ongoing restriction | £25,000 – £65,000 |
| Severe – permanent disability | Multiple fractures, amputation, moderate brain injury | £65,000 – £250,000 |
| Very severe brain or spinal injury | Paralysis, very severe brain damage | £250,000 – £500,000+ |
In catastrophic cases the injury bracket is only the start: future loss of earnings, lifelong care, adapted housing and case management routinely take total settlements into seven figures, well beyond the top of the table.
Claiming for your bike, helmet and kit
Bike damage is claimed at the repair cost, or the pre-accident market value if the frame is written off – not the price of a new equivalent, unless yours was new. Carbon frames that have taken a significant impact are usually treated as write-offs because hidden delamination cannot be ruled out; a bike shop inspection report is persuasive evidence. Claim every damaged item: helmet (always replace a helmet involved in an impact, and claim it), cycling clothing and shoes, lights, GPS computer, phone, glasses and panniers. Photograph everything before repair, keep receipts or bank statements showing what you paid, and get a written repair quote. If you commute by bike, reasonable hire or replacement transport costs while yours is unrideable are also recoverable.
Hit-and-run and uninsured drivers: the MIB
Around one in five cyclist collisions reported to claims handlers involves a driver who fails to stop. You are not left without a remedy. The Motor Insurers' Bureau, funded by a levy on every UK motor policy, compensates victims of untraced drivers under the Untraced Drivers' Agreement 2017 and of uninsured drivers under the Uninsured Drivers' Agreement 2015. Injury compensation follows the same Judicial College principles as an ordinary claim. Two practical points matter: report the collision to the police promptly – unreasonable delay is the most common reason untraced-driver claims fail – and note that property damage (your bike) is only paid in untraced cases where the vehicle is later identified or the crash also caused significant injury. Dashcam and helmet-camera footage, partial number plates and witness details all dramatically improve the chance of tracing the driver and converting the claim into an ordinary insurer claim.
The helmet myth: contributory negligence explained
Insurers sometimes argue that a cyclist who was not wearing a helmet should have their damages cut. The legal reality is narrower than the myth. There is no law requiring adult cyclists to wear helmets in the UK – the Highway Code merely advises it. In Smith v Finch (2009) the High Court accepted that not wearing a helmet could in principle amount to contributory negligence, but only where the insurer proves the helmet would actually have prevented or reduced the specific injury – and on the facts it made no deduction, because the impact speed exceeded what a helmet is designed for. Helmets are certified for impacts around 12 mph; most car-versus-cyclist head strikes are faster. By analogy with the seatbelt case Froom v Butcher (1976), even a successful argument would typically cap the deduction at around 15–25%, and it can never affect compensation for injuries a helmet could not have prevented – a broken collarbone, a crushed leg, a damaged bike. In practice, helmet deductions are rare. Genuine contributory negligence arguments – riding through a red light, no lights at night, undertaking a turning lorry – are fact-specific and negotiable; camera footage usually decides them.
Why cyclists are treated differently from drivers
Two rules that squeeze motorists' small injury claims do not apply to you as a cyclist. First, the fixed whiplash tariff introduced by the Civil Liability Act 2018 covers only occupants of motor vehicles, so a cyclist's soft-tissue neck injury is still valued under the Judicial College Guidelines – usually at several times the tariff figure. Second, when the small claims limit for motorists' injury claims rose to £5,000 in 2021, cyclists, pedestrians, motorcyclists and horse riders were deliberately excluded as vulnerable road users: the cyclist limit remains £1,000, which means most cyclist injury claims can be run with recoverable legal costs, and no-win-no-fee representation is widely available. The 2022 Highway Code changes also help on liability: the hierarchy of road users (rules H1–H3) places greater responsibility on drivers, requires them to give way to cyclists going straight ahead at junctions, and codifies the 1.5-metre minimum passing distance.
Worked example
Sam is knocked off at a junction by a driver who turned across him – a classic rule H3 breach, so the insurer concedes full liability. He suffers a fractured collarbone that heals well over four months: estimated band £6,000–£23,000, and with a clean recovery his solicitor values it in the lower half. His carbon frame is written off at a market value of £1,200, his helmet, jacket and computer cost £250 to replace, he loses £900 of earnings during recovery, and physiotherapy plus travel comes to £150. Special damages total £2,500. The calculator shows an estimated total between £8,500 and £25,500; with his good prognosis a settlement in the region of the lower third would be realistic. Had Sam been found 25% at fault for filtering past slow traffic, every element – injury and bike alike – would be reduced by a quarter.
Frequently asked questions
Do I have to wear a helmet to claim compensation?
No. There is no UK law requiring adult cyclists to wear helmets, and not wearing one does not stop you claiming. An insurer can only argue a deduction for contributory negligence if it proves a helmet would actually have prevented or reduced your specific injury – in Smith v Finch (2009) the court accepted the principle but made no deduction. Cuts, fractures and other non-head injuries are unaffected.
Can I claim if the driver drove off or was uninsured?
Yes. The Motor Insurers' Bureau (MIB) compensates victims of untraced drivers under the Untraced Drivers' Agreement 2017 and of uninsured drivers under the Uninsured Drivers' Agreement 2015. Report a hit-and-run to the police as soon as possible – ideally within 14 days for property damage and without delay for injury – as prompt reporting supports an MIB claim.
How long do I have to make a cycling injury claim?
Normally three years from the date of the accident under the Limitation Act 1980. A child injured while cycling has until their 21st birthday, because the three-year clock only starts at 18. Court proceedings must be issued within the limit, so seek advice well before it expires.
Does the whiplash tariff apply to cyclists?
No. The fixed whiplash tariff under the Civil Liability Act 2018 only applies to occupants of motor vehicles. Cyclists are exempt, and the small claims limit for cyclists' injury claims remains £1,000 rather than the £5,000 that applies to motorists – so cyclists can usually recover legal costs even for modest claims.
Can I claim for my bike, helmet and kit?
Yes. Damage to your bicycle (repair cost or pre-accident market value if written off), helmet, clothing, lights, GPS computer and other kit is claimed as special damages. A helmet involved in any impact should be replaced and its cost claimed. Keep receipts, photographs and repair quotes as evidence.
What if the accident was partly my fault?
Compensation is reduced by your percentage share of blame – called contributory negligence. If damages are assessed at £20,000 and you are found 25% at fault, you receive £15,000. Liability splits are negotiated on the evidence: witness accounts, camera footage and the Highway Code's hierarchy of road users all matter.
