    It's hard to see without sample data, but you could try the following:

     

    Water Consumption Difference Totals =
SUMX (
    ADDCOLUMNS (
        SUMMARIZE (
            uvw_tcUtilityReading,
            uvw_tcUtilityReading[AccountName],
            uvw_tcUtilityReading[UtilityEndDate],
            uvw_tcUtilityReading[UoM]
        ),
        "DiffTotal",
            IF (
                ISBLANK (
                    CALCULATE (
                        [Total Consumption],
                        PARALLELPERIOD ( uvw_tcUtilityReading[UtilityEndDate], -1, MONTH )
                    )
                ),
                BLANK (),
                CALCULATE (
                    [Total Consumption],
                    PARALLELPERIOD ( uvw_tcUtilityReading[UtilityEndDate], -1, MONTH )
                ) - [Total Consumption]
            )
    ),
    [DiffTotal]
)

Glad it worked. Just a quick Recommendation: for Time Intelligence functions (PARALLELPERIOD etc) you should be using a Date Table as a dimension table, or you might find unexpected results.

So just create a date table, connect them, and then update the formula above to be as shown below?

    Exactly! Just make sure the field in the matrix is the Date [Date] field instead of the field from the main table

    (The date table should contain continuous dates covering the range of dates in the model)

    Edit: once you've created the date table, mark it as such using the option in the ribbon
