If you operate your business in Northern Ireland or Scotland, your business may need a pollution prevention and control (PPC) permit from your environmental regulator before it can operate. The PPC regulations contain lists of all the types of operations that require a permit. For example, you will need a permit if your business has a production capacity above a certain level or you use certain hazardous substances.
There are separate PPC regulations in Northern Ireland and Scotland.
If you operate your business in England or Wales, see the NetRegs guidance on environmental permitting.
