WATT Tool Download Area

The latest  version of the software can be downloaded from here.

Note: Before the Microsoft Excel software will run, you will be asked  to  authorise macros and Data links – this will be automatically prompted by Excel on opening the file. How this is achieved varies between versions of Excel, but will be a simple one or two step process to accept and is only required on the initial use of the spreadsheet. The tool will not operate correctly  without this authorisation.
