Fracking is regulated by multiple bodies, including the Department of Energy and Climate Change (DECC), which issues Petroleum Exploration and Development Licences (PEDLs), and the Mineral Planning Authority (MPA), which assesses oil and gas planning applications. The Environment Agency (EA) is responsible for protecting water resources and evaluating the use of chemicals in the fracking process. At the same time, the Health and Safety Executive (HSE) monitors well integrity and site safety.
