If you operate an industrial process that falls under Schedule 1 of the Environmental Permitting Regulations 2010 you'll need to apply for an environmental permit. Fees vary depending on the type of permit being applied for.
There are three types of permits:
Part A1 permits
These permits cover the most polluting industries like large-scale power stations, chemical works and pharmaceutical production. A1 premises are regulated for emissions to air, land, water and other environmental considerations such as noise, vibrations, waste and energy usage. You'll need to apply to the Environment Agency for one of these permits.
