You have received enforcement action

If the Environment Agency, SEPA, NRW, or NIEA has contacted you about a breach of environmental law, this journey explains what to do next. The type of action you have received determines your options and how urgently you must respond.

  1. Identify what type of enforcement action you have received

    Environmental regulators use a graduated enforcement approach. The action you have received tells you how seriously the regulator views the breach.

    • Advisory letter or written warning - The regulator has identified a problem and is asking you to put it right. No formal legal deadline, but failure to act may lead to escalation.
    • Compliance notice - A formal notice requiring you to take specific actions to return to compliance. This is legally binding and carries a deadline.
    • Enforcement notice - A more serious notice requiring you to stop or remedy a breach. Non-compliance is a criminal offence.
    • Suspension or stop notice - Requires you to stop the activity immediately. You must not resume until the regulator confirms it is safe to do so.
    • Prosecution summons - Criminal charges have been brought. Seek legal advice immediately before responding to any further contact from the regulator.
  2. Understand what was breached and why

    Your enforcement notice will reference specific permit conditions or regulations. Before you can respond effectively, you need to understand exactly what the regulator says you have done wrong. Review your environmental permit conditions and identify which ones were breached.

    Review your environmental permit compliance

    Understand your permit conditions, monitoring requirements, and what constitutes a breach. Covers inspections, compliance assessment reports, and the enforcement escalation pathway.

  3. If a pollution incident triggered the enforcement - report it now

    If the enforcement action relates to a pollution incident that you have not yet reported, do so immediately. Self-reporting demonstrates good faith and is a significant mitigating factor when regulators decide on penalties. Call the incident hotline on 0800 80 70 60 (free, 24 hours, all UK nations).

    When and how to report pollution incidents to your regulator. Covers what information to provide, permit breach notifications, and what happens after you report.

  4. Know your rights

    You have the right to challenge enforcement action. How you do this depends on the type of action:

    • Written warnings and advisory letters - No formal appeal route, but you can respond in writing if you disagree with the findings.
    • Enforcement and suspension notices (and permit decisions) - You can appeal to the Secretary of State under the Environmental Permitting Regulations; appeals are administered by the Planning Inspectorate. Your notice will state the deadline for appealing. An appeal may suspend the notice depending on the type.
    • Civil sanctions, including compliance notices - Appeals against civil sanctions under the Regulatory Enforcement and Sanctions Act 2008 go to the First-tier Tribunal (General Regulatory Chamber) within 28 days.
    • Fixed monetary penalties - You can make representations to the regulator within 28 days, or appeal to the tribunal after a final notice.
    • Variable monetary penalties - You can offer an enforcement undertaking as an alternative, proposing your own remediation plan.
    • Prosecution - You have the right to legal representation. Get a solicitor with environmental law experience before speaking further to the regulator.

    Getting legal advice

    For anything beyond a written warning, consider getting legal advice from a solicitor experienced in environmental law. This is essential if you are facing prosecution. The Law Society's Find a Solicitor service can help you locate a specialist.

  5. Demonstrate improvement and prevent recurrence

    Whatever enforcement action you have received, showing that you have taken the problem seriously and put measures in place to prevent it happening again is the single most important thing you can do. Regulators consistently treat genuine corrective action as a strong mitigating factor.

    Prevent pollution from your business

    Practical measures to prevent future incidents: containment, drainage awareness, spill kits, and creating a pollution incident response plan.

    Rebuilding your compliance record

    Your Compliance Assessment Report (CAR) score affects future inspection frequency and subsistence charges. After enforcement action:

    • Complete all required remedial actions within the deadline
    • Submit evidence of compliance to the regulator in writing
    • Review and update your environmental management procedures
    • Train staff on the specific issues that led to the breach
    • Keep detailed records - these demonstrate due diligence at future inspections

    A poor compliance year does not define your business permanently. Consistent improvement over subsequent assessments will restore your compliance band.
