LONDON, July 25 (Reuters) - Britain's BT said it was on track to deliver its financial outlook for the year and its cash flow targets up until 2030 in its first trading update since announcing a path to more than double free cash flow over the next five years.

Britain's biggest mobile and broadband provider had set out its plan to increase free cash flow in annual results in May.

BT said that tight cost control had helped increase earnings in the first quarter, despite a fall in revenue that was in-line with expectations. (Reporting by Alistair Smout, Editing by Paul Sandle)
