Average cost of workplace accidents: What GB employers actually pay

The cost of a workplace accident is spread across multiple categories: sick pay, lost output, cover for absent staff, insurance excesses, investigation time, regulatory fees, legal costs, and, in the most serious cases, fines that can reach several million pounds. Some of these costs are recoverable through insurance, and many are not.

The Health and Safety Executive (HSE) estimates the total annual cost of workplace injuries and new cases of work-related ill health in Great Britain at £22.9 billion for 2023/24, based on its three-year rolling cost model published in January 2026 [1]. That figure covers around 680,000 workers who sustained an injury at work during 2024/25, alongside 1.9 million experiencing work-related ill health [2].

For individual employers, the more relevant figures are the average cost per case and the additional costs that arise once regulatory action or civil claims are involved.

In this article, we’ll discuss the current data on the cost of workplace accidents in the GB: the HSE's unit cost estimates, the share borne by employers, the enforcement landscape as of 2025 and 2026, and the categories of expense that often fall outside standard insurance cover.

Summary

• The HSE estimates workplace injuries and new cases of work-related ill health cost Great Britain £22.9 billion in 2023/24, split £6.5 billion for injury and £16.4 billion for ill health [1].
• The average unit cost is approximately £10,000 per injury and £24,200 per case of work-related ill health [1].
• Individuals bear the largest share (£13.4 billion), followed by government (£5.2 billion) and employers (£4.3 billion) - though employer costs are magnified by uninsured losses [1].
• HSE estimates uninsured losses of £8 to £36 for every £1 recovered from insurers, equivalent to around £315 per employee per year in smaller firms [3].
• The Fee for Intervention rate stood at £183 per hour in April 2025 and rose to £188 per hour from April 2026, applied when a material breach is identified [4][5].
• Average HSE prosecution fines reached £170,000 in the 12 months from August 2024, with total annual fines averaging £44.1 million between 2021 and 2025 [6][7].
• The largest single fine of 2025 was £6 million (Cambridgeshire County Council), followed by £3.2 million (British Airways) and £2.5 million (Industrial Chemicals Ltd) [8].
• Slips, trips and falls on the same level account for 30% of non-fatal workplace injuries, followed by manual handling at 17% and being struck by a moving object at 10% [9].
• Compensation for serious workplace injuries can range from a few thousand pounds for minor cases to over £250,000 for severe permanent harm, based on Judicial College Guidelines [10].
• The cost model excludes long-latency illness such as occupational cancer, meaning the true economic cost of workplace exposure is higher than the headline figure suggests [1].

The HSE cost model: What £22.9 billion covers

The £22.9 billion headline figure comes from the HSE's Costs to Britain of workplace fatalities and self-reported injuries and ill health, updated in January 2026 with data covering 2023/24 [1]. It represents new cases arising from current working conditions and uses a three-year rolling average, so the 2023/24 reference year captures data from 2021/22 through 2023/24.

The two categories that make up the total include:

• injury: £6.5 billion, equivalent to a unit cost of around £10,000 per case
• ill health: £16.4 billion, equivalent to a unit cost of around £24,200 per case [1].

Ill health accounts for approximately 72% of total costs despite injury cases being more visible in day-to-day operations - ill health cases typically involve longer absence and greater long-term impact.

The model includes both financial costs (loss of output, healthcare, benefits payments) and human costs - the monetary valuation applied to pain, grief, suffering and loss of life. It excludes long-latency conditions such as occupational cancer and asbestos-related disease, meaning the actual economic burden of workplace exposure is materially higher than £22.9 billion.

Who pays

The HSE's distributional analysis for 2023/24 shows the £22.9 billion is not borne evenly [1]:

• individuals and their families: £13.4 billion (approximately 59%)
• government and taxpayers: £5.2 billion (approximately 23%)
• employers: £4.3 billion (approximately 19%).

Individuals bear the largest share, driven primarily by human costs and financial losses that fall outside employer sick pay or insurance cover. Government costs include NHS treatment, benefits payments, and lost tax revenue. Employer costs cover sick pay, cover for absent staff, insurance premiums, uninsured losses, and administrative time. The 19% aggregate share reflects average cost distribution across the economy rather than what any individual employer pays when an incident occurs at their premises.

Uninsured losses

Employers' Liability insurance is a legal requirement and covers compensation, medical costs, and defence legal fees. It does not cover the majority of costs that arise from a workplace accident. The HSE estimates that for every £1 an employer recovers from insurers, uninsured losses run at £8 to £36 [3].

Uninsured costs typically include statutory sick pay and any enhanced contractual sick pay, cover for absent employees, lost production and disrupted schedules, damaged product or materials, overtime for existing staff, recruitment and training costs where an injured worker cannot return, management time spent on investigation, increased insurance premiums at renewal, and reputational impact with customers or contractors.

Applying the HSE and RoSPA costing model, uninsured accident costs are estimated at around £315 per employee per year in smaller firms, before any fine, insured claim, or one-off compensation payment is factored in [3].

The most common causes and where costs concentrate

Five causes account for the majority of non-fatal workplace injuries in Great Britain, according to 2024/25 HSE data drawn from RIDDOR employer reports [9]:

• slips, trips and falls on the same level: 30%
• handling, lifting or carrying: 17%
• struck by moving object: 10%
• acts of violence: 10%
• falls from height: 8%.

Slips, trips and falls remain the single largest cause of non-fatal workplace injury and have been for many years [11]. Applied to the 680,000 non-fatal workplace injuries in 2024/25, approximately 204,000 were slips, trips or falls on the same level. Falls from height account for a smaller share of non-fatal injuries but a much larger share of fatalities - 35 of 124 worker deaths in 2024/25 [12].

Cost concentration follows sector risk profiles. Accommodation and food services now has the highest rate of workplace non-fatal injuries, with construction, transportation and storage, and retail also showing above-average rates [12]. Construction accounted for 35 fatalities in 2024/25, making it the sector with the highest number of worker deaths [13].

Regulatory costs: Fee for Intervention and prosecution fines

Where an HSE inspector identifies a material breach of health and safety law, the Fee for Intervention (FFI) scheme allows the regulator to recover the cost of its investigation directly from the business. The hourly rate has increased steadily since the scheme was introduced in 2012 at £124 per hour. It reached £183 per hour on 1 April 2025 [4] and rose to £188 per hour on 1 April 2026 [5].

FFI charges apply from the point a material breach is identified through to closure of the case, covering inspector time on site, follow-up work, statement-taking, notice-issuing, and specialist support. The average FFI invoice is around £700 to £875 [14][15], and more complex cases involving multiple visits or extended investigation can result in higher figures. Businesses receive an invoice every two months and are expected to pay within 30 days of receipt.

Prosecution fine levels

The HSE achieved a 96% conviction rate in 2024/25, securing 246 prosecutions and reporting £33 million in fines during that period [16]. Analysis covering the 12 months from August 2024 puts the average prosecution fine at £170,000 [6][17].

Freedom of Information data covering 2021 to 2025 shows British businesses were fined an average of £44.1 million per year for health and safety breaches, with 2025 recording £40.9 million [7]. The number of serious breaches resulting in prosecution charges rose year on year: 428 in 2023, 446 in 2024, and 496 in 2025 [7].

The largest fines of 2025 included [8]:

• Cambridgeshire County Council: £6 million plus £300,000 costs, following three deaths on the Guided Busway over a ten-year period
• British Airways: £3.2 million, following serious injuries to baggage handlers
• Industrial Chemicals Ltd: £2.5 million, following a major acid leak

Under the Sentencing Council guidelines for health and safety offences, fine levels are scaled to organisational turnover and to the level of culpability and harm involved. Large organisations (turnover above £50 million) can face fines in the millions for equivalent offences that would attract lower penalties for an SME.

Civil claims and compensation

Beyond regulatory action, employers face civil liability for injuries their employees suffer as a result of workplace failings. Compensation awards are calculated in two parts: general damages (for pain, suffering, and loss of amenity) and special damages (for actual financial losses including lost earnings, medical costs, and rehabilitation).

General damages are assessed against the Judicial College Guidelines (JCG), currently in their 18th edition published in April 2026 [18]. Illustrative brackets from the JCG show the scale of exposure:

• Minor injury (e.g. mild concussion): £3,000-£12,000 general damages, with total awards often reaching £4,000-£13,000 once special damages are added
• Moderate injury: £15,000-£36,000 general damages, with total awards reaching £26,000-£48,000
• Serious permanent injury: £50,000-£120,000 general damages, with total awards potentially exceeding £150,000
• Severe back injuries: up to £196,450 in the most serious cases [10][19]
• Brain injury and loss of limb cases: over £250,000 [20]

Individual settlements can reach much higher figures where lifelong care, home adaptations, or permanent loss of earnings are involved.

Working days lost

In 2024/25, an estimated 40.1 million working days were lost across Great Britain due to workplace injury and ill health [21]. Of these, approximately 35.7 million were lost to work-related ill health and 4.4 million to workplace injuries. That total is equivalent to 200,000 full-time workers missing an entire year of work [22]. For individual employers, the average injury results in several days off, with more serious cases leading to weeks or months of absence, often followed by phased returns.

CIPD data for 2025 puts average sickness absence at 9.4 days per employee, the highest in more than 15 years, up from 7.8 days in 2023 [3]. Public sector absence averaged 13.3 days against 9.1 in the private sector.

Under-reporting of workplace injuries

There is a persistent gap between self-reported and formally reported workplace injuries. The Labour Force Survey records around 680,000 self-reported non-fatal injuries in 2024/25, but employers formally reported only 59,219 under RIDDOR during the same period [12]. Many less serious injuries fall below the RIDDOR reporting threshold, which generally requires injuries resulting in more than seven days of incapacity, or specified injuries such as fractures and amputations. Some incidents that should be reported are not. The operational impact on any given business is often larger than RIDDOR figures alone would indicate.

Small business exposure

For smaller employers, a serious injury can absorb a disproportionate share of resources through cover requirements, management time, and operational disruption. Where multiple staff are involved in a single incident, the effect compounds.

Applying the HSE cost model, a 20-person business carries an implicit uninsured accident cost of roughly £6,300 annually before any specific incident occurs [3]. A single prosecution fine at the average level (£170,000) would exceed a full year of typical operating profit for many SMEs. Employers' Liability insurance premiums also vary considerably by sector and claims history: office-based businesses typically pay from £60-£150 per year for basic cover, while construction, manufacturing, and care businesses can pay several thousand pounds annually for equivalent policies.

Costs not included in the HSE model

The HSE cost model does not capture every category of expense an employer may incur. Areas not included or understated in the £22.9 billion figure are long-latency illness (occupational cancer, asbestos-related disease, hearing loss from exposure decades earlier), reputational cost (lost customers, contractor de-listing, difficulty recruiting), management time spent on investigation and liaison, staff turnover following a serious incident, and legal or consultancy fees incurred defending regulatory action.

These costs are difficult to quantify at aggregate level but often represent a substantial portion of the total bill from a specific incident.

Preventive spend as a comparison point

Basic risk assessments, staff training, equipment inspections, and workplace adjustments typically cost a fraction of what a single serious incident will cost to manage. Manual handling training sessions run from around £30-£175 per person, and a workplace needs assessment through the Access to Work scheme is available at no cost to eligible employees [23]. Noise-cancelling equipment, adjustable workstations, and improved lighting all fall well below the £315-per-employee uninsured cost estimate for accidents.

The HSE reports that most workplace incidents are preventable. The cost ratio between prevention and response varies by sector and incident type.
