Serco Group plc

Pre-close Trading Update

2 December 2005

Ahead of its financial year-end on 31 December 2005 and its pre-close meetings
with analysts, Serco Group plc ('Serco') today releases the following update on
current trading:

During the second half of the year, Serco has continued to generate strong
organic growth and benefited from the contributions and synergies of recent
acquisitions. As a consequence, Serco is on track to deliver its expectations
for 2005.

Since 1 July, Serco has won or been appointed preferred bidder for contracts
valued at approximately £1.2bn. These include large and complex contracts such
as the Atomic Weapons Establishment extension, Scottish electronic monitoring
and the Docklands Light Railway rebid. Serco has also won strategically
significant contracts which open up new markets for growth, such as the
Cyclamen programme in homeland defence. Serco continues to win many other
contracts, examples of which are included in a separate news update released
today, available from www.serco.com.

Serco Solutions and Serco Inc have delivered pleasing performances in the
second half and are trading in line with our expectations. Serco Solutions'
revenues have shown good growth compared with the first half of 2005 and the
new skills brought to Serco are bringing benefits, including winning the Small
Business Service contract and securing membership of a consortium bidding for
the e-Borders programme. Serco Inc continues to receive a strong flow of task
orders, as well as expanding or extending existing contracts. In addition, our
increased scale and capability in North America are allowing us to bid new
opportunities which previously could not have been pursued.

Overall, market conditions remain strongly in our favour. We have a significant
bid pipeline and a wide range of further opportunities to grow revenues and to
increase margins. We are confident of delivering double-digit growth for the
foreseeable future.
