SCOTTISH AND SOUTHERN ENERGY PLC

SALES PERFORMANCE OF SOUTHERN ELECTRIC CONTRACTING


Southern Electric Contracting (SEC), the mechanical and electrical contracting
subsidiary of Scottish and Southern Energy plc ('SSE'), will end the financial
year with an order book in excess of £90m for the first time.


The order book has been supported by significant contract wins with a number of
leading organisations such as Marks and Spencer, Texaco and IBM.


The announcement was made as SEC hosted a customer seminar in London on the
development of low carbon buildings.


SSE's financial year will end on 31 March 2007 and it expects to report another
increase in operating profit in its Contracting, Connections and Metering
activities in its preliminary results on 31 May. They delivered £47.0m operating
profit* in 2005/06.


SEC is involved in industrial, commercial and domestic mechanical and electrical
contracting, electrical and instrumentation engineering and public and highway
lighting.


One of the largest mechanical and electrical contracting businesses in the UK,
it operates from 55 regional offices throughout Great Britain and trades as
SWALEC Contracting in Wales, Scottish Hydro Electric Contracting in Scotland,
and Eastern Contracting in the east of England.


It employs 3500 people and recruited 94 apprentice electricians during 2006 and
expects to recruit a further 200 apprentices during 2007.


Speaking at the seminar, Ian Marchant, Chief Executive of SSE, said:


'Our mechanical and electrical contracting business employs more people than any
other part of SSE, and is a genuinely national business with activities
throughout the country. Over the years it has built up a strong track record
which has enabled it to retain existing customers and attract repeat business
and win new customers and attract new business.'


Adrian Pike, Group Managing Director of SEC, said:


'I am confident that SEC is well-placed to deliver further growth in the years
ahead, and the development of low carbon buildings is an example of where new
business opportunities will arise, with SEC now the preferred installer for
Solarcentury. Our past success has been founded on delivering first class
customer service, and that's where our future success lies as well.'


* This excludes £3.4m of operating profit from Thermal Transfer, which was sold
on 31 March 2006.
