Pollution and environmental claims: what expert support costs

Why environmental claims are expensive to run

Environmental losses rarely follow the pattern of a fire or flood. The extent of contamination may only emerge after sampling, remediation can take years and regulators such as the Environment Agency in England or the EPA and state agencies in the US may dictate what has to be done. Cover can sit in an environmental impairment liability policy, a pollution legal liability policy, a limited extension under a general liability policy or a property policy with a clean-up sub-limit.

The policyholder's expert must therefore combine coverage knowledge with an understanding of environmental consulting, remediation contracting and regulatory processes. That breadth, and the duration of many files, drives cost.

• Analysis of the pollution trigger: sudden, gradual or discovery-based
• Coordination with environmental consultants and regulators
• Review of remediation options and cost estimates
• Third-party and regulatory exposure quantification
• Negotiation and settlement over a long period

Indicative fee bands for environmental claims

No official scale exists for policyholder experts on pollution claims in the UK, US, Canada, Australia or Ireland. The table on this page is an indicative order of magnitude observed on the market, not an official or legal tariff. Many environmental claims are handled on a time basis, so the table includes percentages where they are used and notes the common alternatives.

Where a US public adjuster handles a first-party clean-up claim, state licensing and fee rules apply. Liability elements are usually managed by defence counsel appointed under the policy, whose fees are often covered as defence costs.

Indicative amounts, to be checked with each expert.

Time-based versus outcome-based pricing

Because the final amount may not be known for years, many advisers bill hourly or daily rates, possibly with phase budgets: investigation, remediation design, implementation and closure. Percentage arrangements tend to be used for first-party clean-up claims with a defined scope, or for disputes over a specific declined amount.

Hybrid models combine a reduced hourly rate with a success element tied to the uplift over the insurer's position, aligning interests without making the adviser wait years to be paid.

Consultants, laboratories and remediation contractors

Environmental consultants, laboratory analysis, hydrogeological modelling and remediation contractors represent the bulk of the cost of an environmental incident. When retained with insurer consent, these costs may be covered as clean-up or investigation costs. If the policyholder commissions its own consultant to challenge the insurer's preferred approach, that cost is usually not covered. Taxes such as VAT or GST apply to most fees.

Variables that drive environmental advisory costs

The number of regulators and third parties involved has a strong influence: a spill affecting a river, neighbouring land and a public water supply generates far more work than contamination confined to the insured's own site. The age of the pollution matters too, because historic contamination raises difficult questions about policy periods, prior knowledge and the allocation of cost between successive insurers.

Site complexity, groundwater involvement and the choice between excavation, in-situ treatment or monitored natural attenuation also affect both remediation cost and the expert's workload. A clear technical baseline, established early with a reputable consultant, tends to shorten the negotiation and reduce advisory fees overall.

What the policy may reimburse

Environmental policies typically cover clean-up costs, third-party claims and defence costs, subject to limits, retentions and consent conditions. Some also cover emergency response and investigation costs. They rarely cover the fees of a representative advocating for the insured against the insurer.

Coverage disputes commonly concern whether the pollution was sudden and accidental, when it began, whether it was known before inception and whether remediation goes beyond what regulators require. These questions, and their impact on how much remains uncovered, should shape the decision to appoint an adviser.

Cost by scale of incident

For a small heating oil leak with a clean-up cost around £20,000, independent support is often unnecessary if the insurer accepts the claim; a short review by a consultant may be all that is required. For a £400,000 clean-up of a fuel spill at a depot, where the insurer argues gradual leakage, a time-based adviser with an expert consultant might cost in the order of 8% to 12% of the amount in dispute.

For large contaminated land claims with multi-million remediation and third-party claims, advisory costs are typically managed through phase budgets, caps and regular reviews rather than a single percentage.

Illustration of a phased budget

An insured faces a $1.5 million remediation estimate, and the insurer proposes a cheaper approach at $900,000. The adviser agrees phase budgets of $25,000 for coverage and technical review, $40,000 for negotiation and $15,000 for close-out support, plus a success fee of 10% on any increase. If the agreed figure is $1.3 million, total advisory cost is $80,000 plus $40,000, or $120,000. This is purely illustrative.

Comparing advisers for an environmental claim

Look for direct experience with environmental policies and remediation projects, relationships with reputable consultants and an understanding of the regulators involved. Ask for a phased budget and an explanation of how the adviser will work with defence counsel and the insurer's consultants.

Be cautious of guarantees. Environmental outcomes depend on site conditions, regulatory decisions and policy wording. The engagement letter should set out rates, budgets, caps, success fee base, specialist costs, termination terms and reporting.

Ask, too, how the adviser has handled allocation questions on gradual pollution, where several policy years or insurers may be involved. That expertise can change the recoverable amount considerably and is worth paying for when contamination is historic or its start date is uncertain.

• Interaction with defence counsel
• Specialist and laboratory costs
• Reporting frequency and exit terms

For environmental claims, phased budgets and clear success fee bases keep advisory costs in proportion to the stakes. Further guidance on pollution claims is available on expertdassure.com.
