Public Liability Act Premium Fell 6.2% While the Rest of the Liability Book Grew 11%. That Gap Is the Cover Gap

The General Insurance Council's segment-wise report up to July 2026, released on 13 August 2026, gives the liability book a good quarter. Gross direct premium in India for liability across April to July of FY2026-27 was Rs 2,754.37 crore, up 10.9% on the same four months a year earlier. The growth sits almost entirely in one line: "other liability covers", the bucket that carries directors and officers, cyber liability, professional indemnity and commercial general liability, rose 13.2% to Rs 2,179.34 crore. Workmen's Compensation and Employers' Liability added 7.4% to reach Rs 400.61 crore.

Two lines went backwards. Product Liability fell 6.7% to Rs 101.90 crore. Public Liability (Act), the compulsory cover under the Public Liability Insurance Act, 1991, fell 6.2% to Rs 72.52 crore.

Read the second number against what it is supposed to cover. Every owner in India who handles a hazardous substance above the notified quantity is required to carry that policy. That includes chemical and agrochemical plants, bulk drug units, refineries, fertiliser plants, LPG bottling and storage, firecracker manufacturers, large cold stores running ammonia, and a long tail of process units in every industrial estate in the country. The premium those owners pay between them, across four months, is Rs 72.52 crore. Spread that across every registered hazardous-process establishment in the country and the average premium per site is very small indeed.

A pool that small is not buying risk transfer. It is buying a certificate. And a pool shrinking while the rest of the liability book grows 11% tells you the statutory cover is bought as a filing obligation and nothing else, at a time when the underlying exposure is not shrinking at all.

August 2026 supplied the counter-evidence in a single week. The Hindu reported on 22 August 2026 that two workers were killed and nine injured in a reactor blast at a pharma unit in Yadadri-Bhongir, Telangana. NDTV reported the same day that three engineers were killed in a turbine explosion at a Jharkhand factory. The New Indian Express, also on 22 August, reported five workers injured in a mishap at NTPC's Kaniha plant in Odisha. Nine days earlier, on 13 August 2026, Deccan Herald reported a firecracker factory explosion in Sivakasi, Tamil Nadu that killed one and injured another. On 23 August 2026, scanx.trade reported that a fire at Amber Enterprises' IL JIN factory killed two firefighters.

That is five events in eleven days, spanning pharmaceuticals, power generation, consumer electronics components and pyrotechnics. Between them they produced eight fatalities and fifteen reported injuries, plus plant damage and, in several cases, production stoppage at a site that supplies someone else's assembly line. The mismatch is the point: an event profile of this frequency running against a compulsory liability pool that is contracting. The Telangana reactor blast and the liability stack behind it shows how thin the programme usually is at a unit of that size, and the pattern repeats across the other four.

The Public Liability Insurance Act works on strict, no-fault liability under Section 3 and compulsory insurance under Section 4. The mandatory sum insured must be at least equal to the owner's paid-up capital, capped at Rs 50 crore. Alongside the premium the owner pays a further contribution, not exceeding the premium itself, into the Environment Relief Fund created by the 1992 amendment under Section 7A. Relief is administered by the District Collector rather than fought out with the insurer, which is the point of a no-fault scheme.

The design does what it set out to do: money in a victim's hand quickly, without a negligence contest. What it does not do is indemnify the operator, because the relief scale in the Schedule to the Act was set in 1991 and is measured in tens of thousands of rupees per person. Relief for death sits at Rs 25,000 per person, and the medical reimbursement and private-property heads in the same Schedule are smaller still. The full detail of the mechanism is in our note on no-fault claims under the Act and the Environment Relief Fund.

Now price a real event. Take a reactor failure that kills two operators and injures nine, with blast damage to an adjoining unit and firewater run-off into a drain:

• Statutory relief under the Act for the two deaths: of the order of Rs 50,000 in total.
• Employees' Compensation for the same two deaths, computed on wages: typically Rs 8 lakh to Rs 15 lakh each before interest and penalty.
• Medical and disability cost of nine injured, two with major burns, running to months of treatment and at least one likely permanent partial disablement award.
• Third-party property damage to the neighbouring unit's shed, plant and stock.
• Pollution clean-up, soil and drain remediation, and the cost of complying with a State Pollution Control Board direction.
• Defence costs across a Factories Act prosecution, a police case and any civil claims.

The Act policy responds to the first line. Nothing else on that list is inside it. That is the cover gap the premium data is describing.

Every one of the August events killed or injured workers, and workers are not third parties. Public liability wordings exclude the insured's own employees, which pushes the whole human cost of a process event into the employers' liability layer.

That layer is the Employee's Compensation Act, 1923 where ESI does not apply, and the Employees' State Insurance Act, 1948 where it does. Under the EC Act, death compensation is 50% of monthly wages multiplied by the age-based relevant factor, subject to a statutory minimum of Rs 1,20,000; permanent total disablement is 60% of monthly wages multiplied by the same factor, minimum Rs 1,40,000. Wages for the computation are taken subject to the notified monthly ceiling of Rs 15,000. Section 4A adds interest and, where the delay is unjustified, a penalty of up to 50% of the compensation on the employer.

The failures we see on claims files are almost always in the schedule, not in the wording:

1. Wage rolls declared at the ESIC threshold rather than at actual pay. A plant with skilled operators on Rs 45,000 a month declares them at Rs 21,000 because someone has confused the ESI coverage threshold with the wage roll the policy is rated on. The premium is then computed on a wage bill that does not exist, and at claim the insurer has a proportionate-settlement argument on every head the statutory formula does not cap, including common-law claims and defence costs.
2. Contractor helpers left off the roll. The men on the floor at a shift change are frequently not on the principal's payroll.
3. Stale declarations. The schedule was filed at inception and never adjusted after two wage revisions and a headcount increase.

Our guide to workers' compensation and the Employees' Compensation Act sets out the computation in full. The underwriting point is simpler: rate and size the EC policy on the actual wage roll, refreshed at renewal, and never on an ESI threshold that decides an entirely different question.

In a hazardous-process plant the maintenance crew, the loading crew and often the night shift come through a labour contractor. The Contract Labour (Regulation and Abolition) Act, 1970 makes the principal employer liable for wages and welfare where the contractor defaults, and the EC Act's definition of employer reaches the principal in the standard chain. In practice, when a contractor's worker dies at a client site, the claim lands on whichever party has assets and a policy.

The usual defence is a clause in the work order requiring the contractor to hold Employees' Compensation cover and to indemnify the principal. That clause is worth exactly as much as the verification behind it. Three things have to be true at the moment of the accident, not at the moment the contract was signed:

• The contractor's EC policy is in force on that date, with premium paid.
• Its wage schedule includes the men who were actually on site, at their actual wages.
• The principal is named as an additional insured or the policy carries a cross-liability arrangement, so the principal's own defence costs are picked up.

Collect a certificate of insurance at every contractor mobilisation and re-verify at renewal. A certificate that expired three months ago is the most common finding in a post-loss file review, and by then the principal is the only solvent defendant.

Four layers, each doing a job the others cannot.

Layer 1: the Act policy. Sized to paid-up capital up to the Rs 50 crore ceiling, with the Environment Relief Fund contribution paid alongside the premium. This discharges the Section 4 obligation and funds no-fault relief. Treat it as compliance, and never as the risk-transfer programme.

Layer 2: commercial general liability. This is where the real third-party money sits: bodily injury and property damage to neighbours and visitors, defence costs, and product exposure where the plant sells into someone else's process. Buy it with a sudden and accidental pollution extension, because the standard pollution exclusion would otherwise strip out the clean-up and remediation cost that a reactor blast or a firewater event generates. Watch the structure of the limits, per accident and in the annual aggregate, and read the policy wording on whether defence costs sit inside or outside the limit. Our commercial general liability guide covers the wording variations across the Indian market.

Layer 3: Employees' Compensation, sized on the wage roll. Actual wages, actual headcount, refreshed at renewal, with contractor labour either on the principal's schedule or provably on the contractor's.

Layer 4: contractor indemnities, verified. Certificates on file, dated, checked at the gate, with the principal named where the exposure justifies it.

The premium arithmetic is not the obstacle people assume. The Act cover is among the cheapest lines a process unit buys, which is what a national four-month pool of Rs 72.52 crore implies. A liability insurance programme with a Rs 10 crore to Rs 25 crore CGL limit and a pollution buy-back is a materially larger line, but it is still small against a single fatality award plus one neighbour's property claim. The reason the Act pool is shrinking while the rest of the liability book grows is not price. It is that nobody at the plant has been shown the arithmetic above.

No Indian insurer writes a meaningful CGL limit with a pollution extension on a hazardous-process site off a one-page proposal form. The submission that gets terms looks like this:

1. Hazardous-substance inventory. Each substance, maximum quantity stored and in process, storage form, and the applicable threshold under the Manufacture, Storage and Import of Hazardous Chemical Rules, 1989. This is also what determines whether the Act applies at all.
2. Process description and hazard study output. Reaction chemistry, exothermic steps, the HAZOP or What-If study report with the action list and its closure status. An open action list from a study done four years ago is a rating factor.
3. Statutory approvals. Factory licence, Consent to Operate from the State Pollution Control Board, PESO licences where applicable, and the on-site emergency plan.
4. Five-year loss record, including near-misses and reportable incidents to the Factory Inspectorate, not only insured claims. Underwriters read the near-miss log more carefully than the claims list, because it is the only forward-looking data in the file.
5. Neighbour and boundary map. Distance to the nearest occupied building, adjoining units, public road and water body. Third-party severity is a geometry question before it is a chemistry question.
6. Wage roll and headcount, split between direct employees and contract labour, with the contractor list and their EC policy details.
7. Effluent and drainage layout, with the containment arrangement for firewater. This single drawing decides whether a pollution extension is offered or declined.
8. Contractor control documents, work permit system, hot work permit records, and the certificate-verification process at the gate.

Assembling this takes about two weeks the first time and two days at every renewal after. It also hands the risk manager an internal record of exactly which exposures are uncovered, which is the argument that gets the CGL budget approved.

The Council data is a market-level signal, but it resolves into a specific question at every hazardous-process site: is the Act policy the only liability cover in the file?

• Pull the current schedule and confirm the Act policy sum insured against paid-up capital, and confirm the Environment Relief Fund contribution is being paid alongside the premium.
• Check whether a CGL policy exists and whether it carries a sudden and accidental pollution extension. If the pollution exclusion is unmodified, treat the clean-up exposure as uninsured.
• Rebuild the Employees' Compensation schedule from the payroll register rather than last year's declaration.
• Re-verify every contractor certificate on site today, and move verification to the gate.
• Price the worst realistic event on the boundary map and compare it against the aggregate limit rather than the per-accident limit.

The gap between a compulsory pool of Rs 72.52 crore and the loss cost of a single week in August is not a market curiosity. It is an uninsured balance-sheet item sitting at a few thousand process plants.

Reading the Act policy, the CGL wording and the pollution extension side by side is what tells a broker exactly where each layer stops. Sarvada gives commercial insurance brokers structured, searchable access to insurer policy wordings and the intelligence around them, so the boundary between statutory compliance and actual cover is clear before an incident tests it.
