                        UNITED UTILITIES TRADING UPDATE                        

United Utilities Group PLC today issues an update on trading for the six months
ending 30 September 2010. The company will announce its half year results on 24
November 2010.

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,
reflecting the impact of the recent regulatory price review.

"In line with our strategy of focusing on our core activities, we have now
agreed the sales of the vast majority of our non-regulated businesses for a
total enterprise value of approximately £600 million.

"We believe that, with the group's consistent focus on its core activities and
the low cost of its debt portfolio, we are well positioned to deliver
outperformance over the 2010-15 regulatory period."

Regulated activities

The 2010-15 regulatory price review sees customers of United Utilities Water
(UUW) benefit from lower prices and higher levels of capital investment that
help deliver improved service and meet strict environmental standards. The new
price limits took effect from 1 April 2010 and included a 4.3% real price
decrease for 2010/11.

In line with these new price limits and as expected, underlying operating
profit in the regulated business is anticipated to be lower compared with the
prior year. This also reflects continuing cost pressures, including an expected
increase in property rates and depreciation, partly offset by a reduction in
power costs. It is anticipated that infrastructure renewals expenditure and
depreciation will be higher in the second half of 2010/11 compared with the
first half of the year. As outlined previously, capital expenditure is expected
to remain at high levels this year.

UUW has a strong focus on operational performance and is on course to meet its
regulatory leakage target for the fifth consecutive year. In addition, UUW
expects to have improved its position in Ofwat's 2009/10 wastewater
non-infrastructure serviceability assessment, returning all four asset classes
to a "stable" rating. The business remains focused on delivering further
operational and service level improvements for customers.

Non-regulated activities

In line with its strategy of focusing on core activities, over the last half
year, the group has entered agreements to sell the vast majority of its
remaining non-regulated businesses*. Completions of the various non-regulated
disposal transactions are subject to a number of consents and regulatory
approvals and are expected to take place in the second half of the year.

Taken together with the sales of its holdings in Northern Gas Networks and
Manila Water Company, completed during the second half of 2009/10, the group
has now agreed non-regulated disposals for a total enterprise value of
approximately £600 million. United Utilities intends to retain the proceeds
from these disposals within the group.

Since United Utilities has now sold or agreed to sell the vast majority of its
non-regulated businesses, it is expected that the non-regulated activities
segment will be treated as discontinued in the 2010/11 financial statements.

All other segments

United Utilities Property Services is expected to deliver a small underlying
operating profit in the first half of this financial year, reflecting
continuing difficult conditions in the UK property market. As a result, other
activities, which include central costs, are expected to make a small
underlying operating loss for the six months ending 30 September 2010.

Other financial

United Utilities' financial position remains robust and the group has headroom
to cover its projected financing needs through to the summer of 2012.

The impact of the staged reduction in the rate of corporation tax together with
the changes to capital allowances, announced in the UK Government's budget on
22 June 2010, is anticipated to be broadly neutral in cash terms for United
Utilities over the five years to 31 March 2015. However, the changes are
expected to result in an accounting deferred tax credit in excess of £200
million over the five-year period, with the deferred tax credit in the 2010/11
income statement expected to be approximately £50 million.

Group borrowings, net of cash and short term deposits and derivatives, at the
half year are expected to be moderately higher than the position at 31 March
2010, subject to no material further fair value movements and assuming that no
further cash proceeds are received from the agreed non-regulated sales on or
before 30 September. This principally reflects expenditure on the regulatory
capital investment programmes, payment of the 2009/10 final dividend and
payments of interest and tax, partly offset by operational cash flows.

One-off costs in the order of £15 million, relating to continuing operations,
are expected in the first half of 2010/11. These costs principally reflect
business restructuring.

Dividend

As announced in January, the board intends to pay a total dividend per ordinary
share of 30 pence for the 2010/11 financial year. Thereafter, the intention is
to continue to target a dividend per share growth rate of RPI+2% per annum
through to 2015.
