                           MATCHING SHARE AWARD PLAN                           

The ordinary shares in United Utilities Group PLC shown in column 1 below were
allotted in the UK on 15 June 2012 using the market price at the close of
trading on the London Stock Exchange on 14 June 2012, to the undernoted
directors and persons discharging managerial responsibility in exchange for
full market value. These shares will constitute `investment shares' as defined
in the rules of the United Utilities Group PLC 2008 Matching Share Award Plan
(the `Plan') which was approved by the shareholders at the general meeting on 1
July 2008.

On 15 June 2012, the trustees of the Plan also granted awards in the UK, over
`matching shares' as defined in the rules of the Plan as shown in column 2
below, calculated using the market price at the close of trading on the London
Stock Exchange on 14 June 2012 of £6.805 per ordinary share. The award gives
each director/PDMR an option to acquire up to a maximum number of ordinary
shares (as shown in column 2) in United Utilities Group PLC at nil cost to them
subject to the rules of the Plan. The actual number of ordinary shares which
will vest will depend upon the extent to which the established performance
conditions are satisfied over the performance period. Under the rules, the
awards are subject to uplift for notional dividends made or paid during the
performance period.
