The March 2021 budget means that, from 1st April 2022, red diesel will only be supplied for a shorter list of applications.
The implications of these changes on your business will depend on what industry you are in, and what you are using the fuel for. Some sectors that have lost out on the tax relief include construction and manufacturing, as well as some uses for transport and logistics.
For businesses in these sectors, there will be a significant cost increase. Switching to regular white diesel can potentially increase their fuel spend by up to 500%.
