A Guide to Identifying the Correct Permit Type for Medium Combustion Plants

The Medium Combustion Plant Directive (MCPD) is an EU directive which regulates pollutant emissions from the combustion of fuel in plants with a rated thermal input equal to or greater than 1MWth and less than 50MWth. This will apply to many projects with on-site generation across a wind range of sectors.

To operate such a plant in the UK, requires an environmental permit issued by the Environment Agency. However, there is no one single permit covering all Medium Combustion Plants and Specified Generators and identifying the correct permitting route is key to a timely and successful application.

Such permits can take up to 6 months to secure from the regulator and early application is required to ensure that permits are in place for the combustion plant(s) to be commissioned as planned.

WRM have put together a guide to identifying the correct permit for developments including boilers and CHP appliances which can be read here.
