                        UNITED UTILITIES TRADING UPDATE                        

United Utilities Group PLC today issues an update on trading for the six months
ending 30 September 2009. The company will announce its half year results on 25
November 2009.

Commenting on the group's trading position, Philip Green, Chief Executive,
said:

"The group is on track to deliver results in line with our expectations of a
sound underlying financial performance for the six months ending 30 September
2009.

"Earlier this month we submitted our written response to Ofwat's draft
determination of prices for the 2010-15 period and we will be discussing this
with the regulator ahead of the final determination in November."

Regulated activities

Underlying operating profit in the regulated business, for the six months
ending 30 September 2009, is expected to broadly be in line with the first half
of last year, reflecting ongoing revenue and cost pressures.

United Utilities Water (UUW) is allowed a 6.0% regulatory price increase
(including inflation) for 2009/10, to help fund the high levels of essential
investment in its assets to meet strict environmental standards and deliver an
improved service for customers. However, as indicated previously, reduced water
demand means that regulated revenue growth for the year is expected to be lower
than the allowed price rise. As expected, the company also faces cost pressures
in areas such as power and bad debts, alongside an increase in depreciation.

The business continues to focus on improving operational performance and is on
course to meet its 2009/10 regulatory leakage target of 465 megalitres per day,
having met its target for each of the last three years. Customer satisfaction,
in response to enquiries, has also improved further since the start of this
financial year. In addition, overall service performance, as measured by
Ofwat's OPA score, is on track to improve in the year.

In July, the economic regulator, Ofwat, published its draft determination of
price limits for the 2010-15 period, which for UUW included:

  * a £3.4 billion capital investment programme (2007/08 prices);
   
  * an average annual underlying operating efficiency of 1.8% for the water
    service and 2.4% for the wastewater service;
   
  * a return on capital of 4.5% (post-tax, real); and
   
  * an average annual real price decrease of 0.6% across the five-year period,
    with a real price decrease of 6.3% in the first year.
   
Earlier this month UUW submitted its formal written response to Ofwat ahead of
the final price determination, scheduled for November 2009.

Non-regulated activities

The group expects a marginal increase in underlying operating profit in its
non-regulated business in the first half of the year, compared with the
corresponding period last year.

In June 2009, United Utilities, via the 4D consortium, won a new capital
delivery contract with Southern Water to manage the design and build of a new
wastewater treatment works in the Brighton and Hove area. The contract has now
commenced and the construction phase is expected to take approximately three
years, followed by the potential for a two-year contract to operate and
maintain the new plant.

The contract with Scottish Water, via Scottish Water Solutions Limited in which
United Utilities is a major partner, is expected to come to a natural end in
March 2010.

Other activities

United Utilities Property Solutions (UUPS) is expected broadly to break even in
the first half of this financial year, reflecting difficult conditions in the
UK property market. As a result, other activities, which include central costs,
are expected to make a moderate underlying operating loss for the six months
ending 30 September 2009.

Other financial

United Utilities has headroom to cover its projected financing needs through to
the second half of 2011. Since the start of the 2009/10 financial year, the
group enhanced its liquidity position through the issuance of an additional £
100 million, 5.75% bond maturing in March 2022, an additional £50 million,
6.125% bond maturing in December 2015 and a new £70 million, 2.40%+RPI
index-linked bond maturing in July 2039. United Utilities Water now has in
place around £2 billion of index-linked funding, with an average real interest
rate of approximately 1.8%. The average term to maturity of the group's term
debt portfolio is over 25 years.

The group expects a net cash tax inflow for the half year of approximately £50
million, following agreement with UK tax authorities of prior years' tax
returns.

Borrowings, net of cash and short term deposits, at the half year are expected
to be similar to the position at 31 March 2009, subject to no material further
fair value movements. This principally reflects expenditure on the regulatory
capital investment programmes, payment of the 2008/09 final dividend and
payments of interest, offset by operational cash flows and the aforementioned
net cash tax repayment.

One-off costs in the order of £10 million are expected in the first half of
2009/10, which principally relate to restructuring within the business.
