BT Global Services has reported a five percent reduction in revenues for the first quarter to 30 June, despite increases in order intake.

The telecommunication company's professional services business reported revenues of £1.9 billion in the period, down from £2 billion the same time last year. However, BT Global Services managed to continue to reduce its operating loss, by 31 percent, from £54 million in Q1 2010 to £37 million this year.

BT's total order intake in the quarter was £1.6 billion, up two percent on last year. On a 12-month rolling basis, the order intake was up eight percent.

Chief executive Ian Livingstone attributed the client portfolio growth to a major contract win with the Brazilian Post Office and Telegraph Company, Correios, for managed network services.

"BT Global Services is making further progress in high growth economies and secured its largest-ever contract in Latin America," he said.

Other contract signings in the period included a significant 10-year outsourcing contract with Lancashire County Council for a range of services for local schools and councils, and a contract with National Australia Group for outsourced ICT services.

Overall, the BT group reported pre-tax profit of £533 million, up 20 percent year-on-year, on total revenues of £4.8 billion. BT Global Services contributed the highest amount of revenues of all the group's divisions, closely followed by BT Retail (£1.8 billion).
