Environmental Group Claims

If you or a loved one has been injured or fallen ill after being exposed to dangerous substances, and a wider group has also been affected, you may be able to make a compensation claim. Joining a group claim with other victims is a great way to give your claim the best chance of success.

Making an environmental group claim

Dangerous gases, chemicals and bacteria can all cause serious harm to health. We can be exposed to them through the air we breathe, any surfaces that we touch or the water that we wash and bathe in.
Companies and other organisations have a responsibility to keep us protected from these risks. If they have failed in that duty and you have been injured or fallen ill as a consequence, you may have a right to compensation.

Our expert solicitors can help you claim compensation if you have been affected by:

  • Chemical spills
  • Contaminated water
  • Contaminated land
  • Legionnaires’ Disease, for example in a hotel or on holiday
  • Exposure to noxious gases, including carbon monoxide.

These types of exposure often affect multiple people at the same time. This means that it is often possible to join a group action when making your compensation claim. Joining a group claim can speed up the process, share costs and give you the best possible chance of getting the compensation you deserve.

We have decades of experience with environmental group claims and have been involved with some of the most high-profile cases in recent years, including:

  • Camelford water pollution
  • Coke oven workers' compensation
  • Gower Chemicals cases
  • Broomfield Tip landfill cases.

As one of the biggest personal injury law firms in the country, we have the expertise and the resources to handle group claims of all sizes and covering a wide range of issues.
