The Mining Remediation Authority (MRA) is a public body sponsored by the Department for Energy Security and Net Zero (DESNZ). Our role is to manage the impacts of historic coal mining across Great Britain. Protecting the environment is at the heart of what we do.
We operate more than 75 mine water treatment schemes across Britain, managing water levels in abandoned mines and treating over 231 billion litres of mine water every year. This work helps protect drinking water supplies, rivers and local ecosystems. We are responsible for dealing with ground movement and subsidence where no licensed coal mine operator is responsible, tackling mine water pollution, and addressing a wide range of other mining legacy issues.
Our work plays an important role in supporting the UK Government’s Industrial Strategy and the environmental, social and economic priorities of the UK, Scottish and Welsh governments. As we continue to grow and diversify, our ambition is to become more self‑sufficient and to strengthen our reputation as a world leader in resolving the impacts of mining – supporting communities, protecting the environment and enabling sustainable development for the future.
