Air quality and planning
Commercial furnaces require approval from us as the Local Authority. This is required if they burn:
- pulverised fuel
- solid matter at a rate of 45.5kg or more an hour
- liquid or gaseous matter at a rate equivalent to 366.4 kw
Please contact us to request the relevant information required
Further information will be required for new (non-domestic) chimney stacks. Contact us for more information regarding chimney height approval and if a full D1 Chimney Height Calculation is required.
You will need an environmental permit from the Council if the boiler is using fuel from natural sources (for example, wood pellets) and has a rated thermal input of 20 to 50 mw. Or if the boiler is burning waste or waste-derived biomass, and has an aggregate capacity of 50kg or more per hour.
In general, the environmental permit you need depends on the type and amount of fuel you're burning and therefore will determine who the regulator is. More information on preventing air pollution is here.
If you operate a regulated facility you may require an environmental permit.
