    The tools are available to download in a variety of file formats although mainly in PDF and Excel formats. Some basic information about how to download files is available from the Defra help pages.

    Some of the tools contain macros and some users of MS Excel may need to alter their "macro security settings" to get these tools to run.

    The links on the side navigation show further in depth sections available, in addition to the tools shown on this page.
