As I don't know your data, there is a possibility I wrote you a code that would return some double rows. But that is a problem you can easily handle.

Try it, nevertheless:

SELECT t1.Account,
       t1.Balance,
       t1.BilledAmount,
       t1.fPreviousReading,
       t1.fCurrentReading,
       t1.fConsumption,
       t2.cDescription
  FROM (SELECT Ten.Account,
               ten.DCBalance AS Balance,
               SUM (T.fInclusiveAmount) AS BilledAmount,
               SUM (MRD.fPreviousReading) AS fPreviousReading,
               SUM (MRD.fCurrentReading) AS fCurrentReading,
               SUM (MRD.fConsumption) AS fConsumption
          FROM      _mtblTransactions T
            left join _mtblProperties P ON P.idProperty = T.iPropertyID
            left join Client Ten ON T.iCustomerID = Ten.DCLink
            left join Client Own ON P.iPropertyOwnerID = Own.DCLink AND oWN.Account='11074'
            left join _etblPeriod PER ON T.iPeriodID = PER.idPeriod
            left join _mtblMeterReadingDetails MRD ON T.iMeterID = MRD.iMeterReadingsMeterID and T.iPeriodID = MRD.iBillingPeriodID
            and MRD.iReadingType=0
            and idPeriod='79'
                GROUP BY Ten.Account,ten.DCBalance) t1
  JOIN (SELECT T.cDescription,
               Ten.Account,
               ten.DCBalance
          FROM      _mtblTransactions T
            left join Client Ten ON T.iCustomerID = Ten.DCLink) t2 ON t2.Account = t1.Account AND t2.DCBalance = t1.DCBalance
