The short answer
Environmental insurance is a class of liability cover that responds to pollution events — paying for clean-up, defence, third-party harm, and business interruption. It exists because general liability policies exclude most pollution exposure.
What a typical UK policy covers
- Historic (pre-existing) pollution conditions, even if undiscovered at inception
- New pollution conditions arising during the policy period
- Statutory clean-up under Part 2A and the Environmental Damage Regulations 2015
- Third-party bodily injury, property damage and natural resource damage
- Legal defence and regulatory investigation costs
- Business interruption following a covered pollution event
Why it isn't covered by public liability
Standard public liability wordings limit pollution cover to sudden and accidental events and exclude gradual or historic pollution. Most environmental losses are gradual or historic — so the gap matters.
Who typically buys it
Brownfield developers, real estate funds, waste and energy operators, lenders financing contaminated assets, private equity acquirers, and any business handling fuels, chemicals or waste at scale.
Frequently asked
- What is environmental insurance in simple terms?
- Environmental insurance is cover that pays out when an organisation is held responsible for pollution — including cleaning it up, defending claims, and compensating third parties for harm.
- Is environmental insurance the same as EIL?
- Environmental Impairment Liability (EIL) is the most common product label for environmental insurance in the Lloyd's market. The terms are used interchangeably by most UK brokers.
- Does public liability insurance cover pollution?
- Only narrowly. Public liability policies typically cover sudden and accidental pollution incidents and exclude gradual pollution and historic conditions — which is where most environmental loss actually sits.
