And chief executive David Brown said the group is now well placed to meet its target of achieving a £100m bus operating profit by 2015/2016.
David Brown, group chief executive, said: “I am pleased to report a resilient performance across our operations, with all of our companies seeing growth in commercial revenue in the year to date.
“Whilst we remain suitably cautious about the medium term wider economic outlook, we are encouraged by our robust performance.”
He was updating investors on trading ahead of the end of Go-Ahead’s first half on December 29.
“We are committed to operating in the rail market and are helping to shape the future of the industry through our involvement in the Government’s review of rail franchising,” said Mr Brown.
“For the benefit of passengers, employees and tax payers, it is important that the franchising timetable resumes as soon as possible.”
In the bus market outside of London, Go-Ahead’s fare-paying passenger numbers grew by 5% growth, which was partly offset by a weaker concessionary performance. The company has around 4,600 buses running in the North East, Oxford, East Anglia, the South East and Southern areas.
The firm has a 24% share of the London bus market, where there was “strong underlying growth”, although the effects of the Olympics has now been diluted.
Mr Brown said: “We continue to lead the transport industry in the development of smart ticketing. There are now over 300,000 passengers using our smartcard “the key” and the roll out of mobile ticketing across our bus operations is progressing well.
“We strongly believe that making travel more convenient for our passengers, combined with innovative and targeted marketing, will attract more people onto our services.”
