Whiplash Payout Scale UK 2026: Compensation by Grade (1–5)

Grade 1 covers mild neck pain and stiffness with no physical signs on clinical examination — no muscle spasm, no reduced reflexes, full range of movement. Most people recover fully within a few weeks with over-the-counter pain relief and gentle movement.

The final figure hinges almost entirely on the prognosis period in your medical report. A 4-week recovery lands at the bottom of the band; a 12-week prognosis sits near the top.

Example: Sarah, a 34-year-old office worker, was rear-ended at a set of lights in Leeds. She had two weeks of neck stiffness, took ibuprofen, saw her GP once and returned to normal within six weeks. Her medical report gave a 6-week prognosis. She settled through the OIC portal for £310 plus a small special-damages figure for prescription and travel costs.

Grade 2 involves neck pain with reduced range of movement, point tenderness on palpation and often associated headaches or shoulder pain. Musculoskeletal signs are present but there's no neurological involvement.

Most Grade 2 claimants need a course of physiotherapy — typically 4 to 8 sessions — and the treatment notes strongly influence the prognosis. The gap between the bottom and top of the Grade 2 range is largely driven by how long symptoms actually persist.

Example: Daniel, a 42-year-old delivery driver, was hit from behind on the M6. He had persistent neck pain, headaches and difficulty turning to check blind spots for around five months, took two weeks off work and completed six physio sessions. His prognosis was 5 months with associated minor travel anxiety. He settled for £1,595 plus special damages.

Grade 3 whiplash is the most serious injury the fixed tariff still covers. Alongside neck pain and reduced movement, there are neurological signs — decreased deep tendon reflexes, muscle weakness, or sensory changes in the arm or hand.

Recovery can take up to two years and often involves prolonged physiotherapy, pain management referrals and occasionally imaging (MRI). Because these claims sit near the ceiling of the fixed tariff, it's worth checking whether any element of your injury (for example a fracture missed on initial x-ray) takes you outside the tariff altogether.

Example: Priya, a 51-year-old teacher, was in a T-bone collision in Birmingham. She developed persistent neck pain radiating into her right arm with reduced grip strength, needed 18 months of intermittent physiotherapy and pain management, and had an MRI confirming soft-tissue injury. Her prognosis was 20 months with associated low mood. She settled for £4,215.

Grade 4 injuries involve fracture or dislocation of the cervical spine alongside neck complaints. The moment a fracture is confirmed, the fixed tariff no longer applies — compensation is valued individually under the Judicial College Guidelines, which produce significantly higher figures.

Because these claims exit the tariff, they also exit the OIC portal's small-claims track. A specialist personal injury solicitor is almost always instructed, and settlements usually include general damages plus a substantial special-damages award for lost earnings and future treatment.

Example: Marcus, a 38-year-old scaffolder, sustained a stable C6 vertebral fracture in a rear-end collision. He was in a cervical collar for eight weeks, off work for four months and lost overtime income. His settlement — negotiated by a solicitor — came to £18,500 including special damages for lost earnings and future physiotherapy.

The clinical Quebec Task Force grading runs from Grade 0 to Grade IV — there's no official Grade 5. But the phrase has stuck in search behaviour to describe the worst outcomes: chronic whiplash-associated disorder, permanent range-of-movement loss, or serious ongoing pain preventing return to previous work.

These cases are valued individually under the Judicial College Guidelines. The most serious permanent soft-tissue neck injuries can attract awards in the tens of thousands, and where there's associated catastrophic injury (spinal cord damage, permanent disability), settlements reach well into six figures.

Example: Elaine, a 47-year-old nurse, developed chronic whiplash-associated disorder after a high-speed motorway collision. Three years on she still had daily neck pain, disturbed sleep and a diagnosis of PTSD. She could no longer perform ward duties and moved to a lower-paid administrative role. Her settlement was £62,000, including a Smith v Manchester award for reduced labour-market position.
