A trampoline park injury compensation calculator estimates what a bounce park claim could be worth. Value depends on the severity of injury — commonly a fracture, spinal compression, or head injury — and on whether the operator failed to supervise, pad, or maintain the equipment. Below we explain how trampoline park claims are valued in both the US and UK, and how signed waivers affect the outcome.
How Trampoline Park Injury Compensation Is Calculated
Every claim is built from two components: general damages for pain, loss of amenity, and the effect on your life, and special damages for the financial losses you can prove.
General damages (non-economic damages in the US) reflect the severity and duration of the injury. In the UK, solicitors read across to the Judicial College Guidelines, which give recommended ranges for each injury type by outcome — recovery period, surgical intervention, and any residual disability. In the US, value is settled through negotiation using either the multiplier method, which applies a severity factor to economic losses, or the per-diem method, which sets a daily figure on suffering across the symptomatic period.
Special damages cover every provable cost: A and E or ER attendance, imaging, orthopaedic surgery, physiotherapy, braces or splints, lost wages, travel, care at home, and, in serious cases, future treatment and lost earning capacity. Trampoline park injuries frequently involve high-energy fractures, spinal compression, and, in a small share of cases, head and neck injuries, so projected future costs can form a substantial part of the claim.
Common Trampoline Park Injuries and Their Effect on Value
The mechanism — landing awkwardly, being double-bounced by another jumper, missing a foam pit, or striking exposed framework — shapes the injury pattern and the compensation band.
- Ankle and lower-leg fractures — Frequent from awkward landings and double-bouncing. Value tracks whether surgery, pins, or plates were needed and any residual stiffness.
- Knee ligament injuries — ACL and meniscus damage from twisting landings. Reconstruction and long rehabilitation lift the claim.
- Wrist and arm fractures — Common when jumpers put out a hand to break a fall from a height or into a foam pit.
- Spinal injuries — Compression fractures, disc damage, and, in the most serious cases, cervical injury with neurological loss from head-first landings. The highest bands apply where paralysis follows.
- Head and facial injuries — Concussion, skull fracture, and dental injury from collisions with other jumpers or the frame. Persistent post-concussion symptoms raise the value.
- Child injuries — Younger jumpers on the same trampoline as much heavier adults are at particular risk of leg fractures. Claims for children are held on trust and cannot expire before adulthood.
Medical records, imaging, and the operative report classify the injury, and insurers rely on them when they assess general damages.
Liability, Waivers, and Assumption of Risk
Compensation is only available where the operator was legally at fault. Trampoline parks sit in a distinct area of law because most require a signed waiver before entry.
Operator duties. A park owes a duty to design, maintain, supervise, and enforce house rules to a reasonable standard. Typical breaches include allowing too many jumpers per trampoline, failing to separate adults from children, worn or missing padding on the frame and springs, torn beds, inadequate foam-pit depth, absent or untrained court monitors, and rules that are printed but not enforced. Any of these can support a negligence claim in either country.
US — waivers and assumption of risk. Waivers are widely used and their enforceability varies by state. Courts commonly hold that a waiver can bar a claim for the inherent risks of jumping, but not for gross negligence, reckless conduct, or an operator's failure to meet its own safety obligations. Some states refuse to enforce waivers signed by a parent on behalf of a child, which keeps a minor's claim alive. The related doctrine of assumption of risk reduces or bars recovery where the risk was open and obvious.
UK — Consumer Rights Act 2015 and Occupiers' Liability. A trampoline park cannot exclude liability for personal injury caused by negligence, whether through a signed waiver or a notice at the entrance. The park owes a duty under the Occupiers' Liability Act 1957 to keep visitors reasonably safe, with a heightened duty toward children under section 2(3)(a). A poorly enforced rule against double-bouncing, or missing padding on a frame, will generally found a claim.
Factors That Increase or Reduce Your Payout
Several factors move a trampoline park claim up or down; understanding them keeps expectations grounded.
- Severity and permanence — A clean fracture that heals is worth far less than a spinal or head injury with lasting deficit.
- Age of the injured person — Children carry the injury and any growth-plate consequences for decades, and courts recognise the longer impact.
- Operator record — Prior incidents on the same equipment, missing risk assessments, or ignored maintenance logs strengthen the claim.
- House-rule enforcement — CCTV showing multiple jumpers per trampoline or no court monitor present at the time of the accident is powerful evidence.
- Occupation — Manual workers and the self-employed face larger income losses, which lifts the claim.
- Contributory conduct — Attempting a somersault against posted rules, or jumping while under the influence, can support a contributory negligence argument that cuts the award.
- Insurance and caps — The operator's policy limits and, in some US states, statutory caps on non-economic damages set a practical ceiling.
UK Compensation Bands for Trampoline Park Injuries
The Judicial College Guidelines set recommended ranges by injury type and outcome rather than by activity, so a trampoline case is placed in the band that matches the medical picture.
- Minor — Sprains, soft-tissue strains, and simple fractures that recover within months without lasting effect. The lowest bands, scaled to duration.
- Moderate — Fractures needing fixation, ACL tears requiring reconstruction, or back injuries producing continuing discomfort but a full or near-full recovery.
- Serious — Complex fractures with residual stiffness, moderate brain injury with cognitive effects, or back injuries producing chronic pain and functional limitation.
- Severe — Cervical spinal cord injury with paralysis, severe traumatic brain injury with lasting deficit, or amputation. The highest bands apply, usually combined with substantial future-loss awards.
Special damages are calculated separately and added. A serious ankle fracture in a self-employed builder who cannot work for six months produces a larger total than the same injury in an office worker back on light duties within weeks.
US Trampoline Park Claims: Multiplier and Per-Diem
The US has no national tariff for trampoline injuries. Value is settled through negotiation between the attorney and the operator's insurer, or by a jury if the case is tried.
Under the multiplier method, the attorney totals the economic damages — hospital bills, surgery, physiotherapy, braces, and lost wages — then multiplies by a factor reflecting severity. A wrist fracture that heals fully sits near the lower end of the range; a cervical spinal injury with permanent paralysis supports a much higher factor.
The per-diem method assigns a daily value to pain and inconvenience, then multiplies by the number of symptomatic days. As a worked illustration only, a daily rate of $175 across 200 days of recovery would place the pain component at $35,000; the actual rate and duration turn on the medical evidence. Per-diem is harder to apply once the injury becomes permanent, because the count would extend for life.
The outcome also depends on the operator's policy limits, whether a signed waiver survives challenge, the strength of the CCTV and incident-report evidence, and whether the state caps non-economic damages.
Special Damages Checklist for Trampoline Park Claims
Logging every loss is essential; undocumented items are money left on the table.
- Emergency care — A and E or ER attendance, X-rays, CT or MRI imaging, and any inpatient stay.
- Surgery and follow-up — Fracture fixation, ligament reconstruction, anaesthesia, and post-operative appointments.
- Rehabilitation — Physiotherapy, occupational therapy, and psychological support where post-traumatic symptoms are diagnosed.
- Supportive items — Casts, boots, braces, crutches, wheelchairs, and home aids where mobility is affected.
- Lost wages and school — Payslips or tax returns showing lost income; for a child claimant, records of missed school and any tutoring costs.
- Travel — Mileage, parking, and fares to medical appointments; a log kept from day one is far stronger than reconstructed estimates.
- Care and assistance — Help with personal care, cooking, driving, and childcare, costed at published care rates even if a relative gave it unpaid.
- Future losses — Projected further surgery, long-term therapy, home adaptations, and reduced earning capacity where the medical expert identifies the need.
The Claim Process and Common Mistakes
A trampoline park claim runs through a predictable sequence in both countries. Report the accident at reception and ensure it is entered in the incident log; request a copy. Ask about CCTV — footage is often overwritten within days and preservation letters must be sent quickly. Photograph the trampoline, any missing padding, the foam pit depth, and the surrounding area, and take contact details from witnesses. Seek prompt medical attention so the injuries and their cause are on record.
A personal injury solicitor in the UK or attorney in the US then investigates fault, sends a Letter of Claim or demand letter, arranges an independent medical examination, and negotiates with the insurer. Most claims settle before court. Both countries impose strict time limits to begin a claim, and those limits vary by jurisdiction — a child's claim generally survives until adulthood, but preserving evidence early remains critical.
Common mistakes cost claimants money. Assuming the signed waiver ends the case, without legal review, closes off valid claims. Missing physiotherapy or discharging yourself against advice supports a failure-to-mitigate argument. Accepting the insurer's first offer before the specialist confirms the prognosis undervalues spinal, head, and growth-plate cases. Posting videos of an early return to activity while claiming severe limitation invites a surveillance cut. Losing receipts, and failing to disclose earlier injuries to the same body part, both shrink the award.
Trampoline Park Injury compensation — frequently asked questions
Does a signed waiver block a trampoline park injury claim?
Not automatically. In the UK, the Consumer Rights Act 2015 and Unfair Contract Terms Act 1977 prevent an operator from excluding liability for personal injury caused by negligence, so waivers do not bar a claim. In the US, enforceability varies by state, and waivers generally do not shield gross negligence, reckless conduct, or claims by children where a parent signed on their behalf.
Who is liable when a child is injured at a trampoline park?
Usually the operator, if the accident flowed from missing padding, poor supervision, allowing children on with much heavier adults, or a rule that was printed but not enforced. Children owe a lower standard of care than adults, and their claims are held on trust and generally do not expire before adulthood.
Can I claim if I was double-bounced by another jumper?
Yes, where the park failed to enforce the one-jumper-per-trampoline rule that most operators post. CCTV showing several jumpers on the same trampoline, or the absence of a court monitor at the time, is strong evidence of a breach of the operator's duty.
What are the most serious trampoline park injuries?
Cervical spinal injuries from head-first landings, severe traumatic brain injury from collisions, and complex lower-limb fractures that need surgery. These cases attract the highest general damages in both countries and often include large future-care and lost-earnings components.
How long do I have to bring a trampoline park injury claim?
Both countries impose strict deadlines. In the UK the general limit for personal injury is three years from the date of the accident or knowledge, with different rules for children whose time runs from their eighteenth birthday. In the US the statute of limitations varies by state and defendant type, so early legal advice is essential.
What evidence should I gather after a trampoline park accident?
Report the accident at reception and get a copy of the incident log, request preservation of CCTV in writing before it is overwritten, photograph the equipment and any missing padding, take witness contact details, keep every medical record and receipt, and log all appointments and travel. Early evidence carries far more weight than reconstructed notes.
