Change description : 2026-03-02 11:40:00: Added links to related guidance about checking if you need a licence to abstract or impound water. [Guidance and regulation]
You may need an environmental permit or licence if you do an activity that could:
pollute the air, water or land
increase flood risk
adversely affect land drainage
take water from a surface or underground source
change the water level or flow of an inland water
You are breaking the law if you operate without a permit or licence when you should have one.
What you need a permit or licence for
You need an environmental permit if you operate any of the following:
an ‘installation’ – an industrial facility, manufacturer or other business that produces potentially harmful substances, for example a landfill site, a large chicken farm, a food factory, a furniture factory, a dry cleaners, a petrol station
a waste operation – a site where waste is recycled, stored, treated or disposed of
a mining waste operation – a site which manages waste produced from mines or quarries
a medium combustion plant or specified generator
a small waste incineration plant – where certain types and quantities of waste are burned
mobile plant – plant that’s designed to move or be moved, for example a machine that’s moved ontoon to a site to clean contaminated soil
a solvent emission activity – releasing organic solvents directly or indirectly into the air
Unless your activity is an ‘exclusion’ or an ‘exemption’, you need an environmental permit if you carry out:
a stand-alone water discharge activity that involves releasing polluting liquids to surface water such as rivers or streams
a stand-alone groundwater activity that involves releasing polluting liquids directly or indirectly to water underground
You need an environmental permit for an activity which involves radioactive substances.
You may need an environmental permit for flood risk activities if you do work:
in, under, over or near a main river (including where the river is in a culvert)
on or near a flood defence on a main river
in the flood plain of a main river
on or near a sea defence
You may need a water resources licence if you need to:
abstract (take) water from a surface or underground source
impound water through a dam, weir or other structure
Check if you need a permit or licence and who to apply to
Depending on your activity and the pollution risk, you need to apply to the Environment Agency or your local council. If it’s the Environment Agency, there’s guidance for each activity. This explains whether there are:
exclusions - when you do not need a permit
exemptions - when you do not need a permit but you may need to register
Added a link to the Environment Agency's pre-application advice service for permits.

Updated page to clarify that people with a stand-alone water discharge or groundwater activity should check if they need a permit. Updated the 'Who to apply to' section so the guidance for each type of activity is presented under headings rather than as a table (for accessibility reasons).

Added the requirement for medium combustion plant and specified generators.
