Any business operating in any sectors not included above will now have to ditch red diesel, and use fuel taxed at the standard white diesel rate. The current rate has been running since 2010 and has been frozen for 10 years, and it will of course impact businesses costs. However, the measures were taken after public consultations, which also included ways to help businesses choose greener elements in their operations that would help meet air quality targets.
Businesses who rely on red diesel to heat their premises should be aware of possible increased costs but should look into switching to more efficient heating systems or a less polluting fuel type. It is also recommended to replace or flush out tanks before the diesel tax changes to avoid red diesel traces after switching to white diesel. If you are driving a low emissions car there are government schemes that you may benefit from.
