Medical Malpractice Statistics in UK 2026 | Claims, Payouts & Key Legal Facts

Medical Malpractice in the United Kingdom 2026

Medical malpractice, formally referred to as clinical negligence within the UK legal system, occurs when a healthcare professional’s substandard care causes avoidable harm to a patient. Within England, the vast majority of such claims are managed centrally through NHS Resolution, the arm’s-length body of the Department of Health and Social Care (DHSC) responsible for handling negligence claims against NHS trusts, general practices, and other indemnified healthcare providers. According to NHS Resolution’s official Annual Report and Accounts for 2024/25, the organisation received 14,428 new clinical negligence claims and reported incidents during the year, a 4.7% increase on the previous year and the continuation of a longer-term upward trend in claims volume that has persisted since the mid-2000s, with the exception of a brief pandemic-era dip.

What makes the 2026 medical malpractice landscape especially significant is the scale of the financial liability now facing the NHS, which the National Audit Office (NAO) has flagged as a matter of urgent parliamentary concern. NHS Resolution’s own data confirms its provision for future clinical negligence liabilities reached £60.3 billion as of 31 March 2025, making it the second-largest liability on the entire UK government balance sheet, trailing only nuclear decommissioning costs. At the same time, a Public Accounts Committee (PAC) report has highlighted that low-value claims now cost more in legal fees than the compensation victims actually receive, with a striking 3.7:1 cost-to-damages ratio for claims valued at £25,000 or under. This article draws exclusively on verified data from NHS Resolution’s official Annual Statistics and Annual Report, alongside findings from the National Audit Office and Public Accounts Committee, to present an accurate, comprehensive statistical picture of medical malpractice claims in the UK in 2026.

Medical Malpractice Key Facts in the UK 2026

Before exploring detailed statistical breakdowns, the following key facts establish the scope, financial scale, and structural patterns that define medical malpractice claims across the UK today.

The £3.09 billion paid out in 2024/25 represents a substantial increase from the £2.8 billion paid in 2023/24, continuing a long-term trajectory that the National Audit Office describes as having more than trebled in real terms over the past two decades, climbing from roughly £1 billion to £3.6 billion when comparable cost-of-harm measures are used. Despite this rising financial burden, NHS Resolution’s strategic emphasis on early, non-adversarial dispute resolution has achieved measurable success, with a record 83% of clinical claims resolved without the need for formal legal proceedings in 2024/25 — up from just 66% in 2016/17 — meaning more than 11,110 claims were settled through mediation, negotiation, and other collaborative processes that kept patients, families, and healthcare staff out of court.

Yet this progress in resolution method has not translated into reduced financial exposure. The £60.3 billion provision for future liabilities now stands as the second-largest single liability on the UK government’s entire balance sheet, a figure that has quadrupled over the past two decades according to NAO analysis. Compounding this concern, the Public Accounts Committee’s scrutiny of low-value claims revealed a deeply troubling cost structure: for claims involving damages of £25,000 or less — which constitute roughly three-quarters of all claims by volume — legal fees now cost 3.7 times more than the compensation victims actually receive, a finding that has placed renewed pressure on the Department of Health and Social Care to introduce fixed recoverable costs (FRCs) for lower-value clinical negligence cases, a reform that has been repeatedly delayed since its originally planned implementation date.

Medical Malpractice Claims by Clinical Specialty in the UK 2025

Clinical specialty plays a decisive role in determining both the volume and the financial value of medical malpractice claims, with a small number of high-risk specialties accounting for a disproportionate share of the NHS’s total compensation expenditure.

CLINICAL NEGLIGENCE CLAIMS BY SPECIALTY — UK 2024/25
========================================================
(Share of new claims received, by clinical specialty)

Emergency Medicine        ████████████████░░░░  13.1%
Orthopaedic Surgery         ██████████████░░░░░░  11.5%
Obstetrics                    █████████████░░░░░░░  11.2%
Other specialties (combined)    ████████████████████  38.1%
                                  (anaesthetics, ENT, dermatology, etc.)

COMPENSATION VALUE CONCENTRATION:
  Obstetrics: % of claims        ███░░░░░░░░░░░░░░░░░  ~10-11%
  Obstetrics: % of total value     ███████████████████░  53% (2024/25)

The concentration of claims within emergency medicine, orthopaedic surgery, and obstetrics — which together account for over a quarter of all new clinical negligence claims — reflects the operational pressures inherent to high-throughput, time-critical areas of medicine where workforce shortages and the pace of care delivery most directly affect patient safety outcomes. Emergency medicine’s position as the single largest claims category at 13.1% is consistent with previous years’ data, though the underlying numbers reveal subtle shifts: orthopaedic surgery’s share rose from 10.8% to 11.5% year-on-year, while both emergency medicine and obstetrics saw modest declines in their respective claim-volume shares, suggesting incremental movement in the relative risk profile across specialties even as the overall claims total continues to climb.

The most striking pattern in the specialty-level data, however, is the dramatic disconnect between obstetric claim volume and obstetric claim value. While obstetrics accounts for only around 10-11% of new claims by number, it represents a staggering 53% of the total compensation value paid out across the entire NHS clinical negligence system in 2024/25, with maternity-specific payments alone reaching £1.3 billion. This imbalance stems directly from the nature of harm involved in birth injury cases: claims frequently relate to severe, lifelong brain damage or disability — including conditions such as cerebral palsy — caused by oxygen deprivation during delivery, and because compensation in these cases must fund an entire lifetime of specialist care, housing adaptations, and ongoing medical support, individual obstetric settlements routinely dwarf the average payout in virtually every other clinical specialty, often structured through periodical payment orders (PPOs) that guarantee annual payments for the claimant’s lifetime.

Medical Malpractice Legal Costs in the UK 2025

The legal costs associated with pursuing and defending clinical negligence claims have become one of the most contentious aspects of the entire NHS compensation system, with both claimant and defence costs rising sharply even as overall claim resolution rates improve.

CLINICAL NEGLIGENCE LEGAL COSTS — UK TRENDS
==================================================
(NHS Resolution Annual Report data, 2023/24 to 2024/25)

Claimant legal costs:
  2023/24    █████████████████░░░  £545 million
  2024/25    ████████████████████  £621 million  (+14%)

NHS defence legal costs:
  2023/24    █████████████████░░░  £169 million
  2024/25    ████████████████████  £181 million  (+7%)

LOW-VALUE CLAIMS COST TREND (≤£25,000):
  2014/15 average claimant legal cost   ███████████░░░░░░░░░  £19,776
  2023/24 average claimant legal cost   ████████████████░░░░  £26,095  (+32% since 2014/15)

The 14% surge in claimant legal costs to £621 million in 2024/25 substantially outpaced the 7% rise in NHS defence costs to £181 million, widening an already significant gap between what claimant solicitors recover and what the NHS spends defending itself. This asymmetry becomes particularly stark when examined through the National Audit Office’s long-term lens: claimant legal costs have grown 3.6 times in real terms since 2006/07, compared to a 2x increase in NHS defence costs over the identical period, meaning claimant-side legal costs have consistently outgrown defence costs by a substantial margin year after year, a trend the Association of Personal Injury Lawyers (APIL) attributes significantly to growing delays in claims processing, noting that the average time between claim notification and settlement has increased by 51% over the decade to 2024.

The data also reveals a stark concentration of costs at the highest end of the claims spectrum, with claims valued at £1 million or more accounting for 68% of all legal costs while representing just 2% of total claim volume — illustrating how a small number of catastrophic, lifelong-care cases drive the overwhelming majority of the system’s financial burden. At the opposite end of the scale, the persistent rise in legal costs for low-value claims has become a flashpoint for reform advocates: average claimant legal costs for claims under £25,000 climbed from £19,776 in 2014/15 to £26,095 by 2023/24, a 32% increase, prompting the Public Accounts Committee to recommend that the Department of Health and Social Care urgently pursue alternative dispute resolution mechanisms, noting that keeping a case out of formal litigation saves an average of £96,000 in claimant legal costs alone — savings that proponents argue could be reinvested directly into frontline NHS patient care.

Medical Malpractice Resolution and Outcome Trends in the UK 2025

How clinical negligence claims are ultimately resolved — and how quickly — has shifted substantially over the past decade, with NHS Resolution’s deliberate strategic pivot toward collaborative dispute resolution producing measurable, if incomplete, improvements in claimant and system outcomes.

CLINICAL NEGLIGENCE RESOLUTION TRENDS — UK 2016/17 vs 2024/25
====================================================================

CLAIMS RESOLVED WITHOUT FORMAL LEGAL PROCEEDINGS:
  2016/17   █████████████░░░░░░░  66%
  2024/25    ████████████████████  83%  (record high)

NEW CLAIMS RECEIVED vs CLAIMS RESOLVED (2024/25):
  New claims received      ████████████████████  14,428
  Total claims closed        ███████████████████░  14,431
  Resolved without litigation  ██████████████████░░  11,110

MEDIATION SCHEME RESULTS (SINCE LATE 2016):
  Total claims mediated         ████████████████████  2,031
  Successfully resolved           ██████████████████░░  79%

The improvement from 66% to 83% of claims resolved without formal legal proceedings over an eight-year period represents one of NHS Resolution’s most significant operational achievements, directly reflecting the organisation’s stated strategic priority of “delivering fair resolution” while minimising the emotional toll and expense of court proceedings for patients, families, and healthcare staff alike. Chief Executive Helen Vernon has specifically highlighted that this approach meant more than 11,000 people saw their claims resolved through mediation, negotiation, and other non-adversarial processes in 2024/25 alone, a substantial expansion of NHS Resolution’s formal mediation scheme, which has now handled 2,031 claims since its launch in late 2016 with a consistently strong 79% success rate.

Despite these resolution-process improvements, a structural imbalance persists between the volume of new claims arriving (14,428) and the volume being closed (14,431) — figures that, while nearly matched in the latest reporting year, mask a longer-term trend in which new claims have outpaced closures for several consecutive years, gradually expanding the total pool of open, unresolved claims sitting within the system. This dynamic helps explain why, even as resolution methods become more collaborative and efficient on a per-case basis, the overall financial liability continues to grow: every claim that remains open longer accrues additional legal costs, and as the National Audit Office has noted, NHS Resolution’s own data confirms that the longer cases run, the higher the eventual costs become — a feedback loop that underscores why both faster resolution and genuine reductions in the underlying rate of clinical harm remain essential to controlling the NHS’s mounting medical malpractice liabilities.
