Larger boilers may require a permit under the Environmental Permitting Regulations and, depending on the fuel used, may fall within the requirements of the Waste Incineration Directive.
An increasing number of businesses are looking at biomass as an energy source for providing heat, as well as power. In general, you will need an environmental permit from the council if the boiler is using biomass fuel from natural sources, e.g. wood pellets, and has a rated thermal input >20 MW, or if the boiler is burning waste or waste-derived biomass, and has an aggregate capacity of 50kg or more per hour. Other types of appliance may require a permit from the Environment Agency instead.
For further guidance on how energy from waste plants are regulated, including anaerobic digestors, please visit the GOV.UK website.
