The revised data confirmed that all four major sectors of the economy - services, industry, agriculture and construction - had expanded during the three months to June.
Exports rose 3.6% from the previous three months, helped by the weak pound and a bottoming-out of the eurozone economy, while imports increased 2.5%, meaning that the country's deficit would have narrowed.
"The expenditure breakdown was positive news," said Philip Rush, economist at investment bank Nomura. "Consumption obviously fairly important to the recovery there but... the recovery in the second quarter wasn't as reliant on consumption as we'd feared."
Most economists agree that for the recovery to be sustained, the UK economy needs to rebalance away from the consumer spending that helped drive the boom in the last decade, with greater reliance on industry, investment and exports.
Chris Williamson, chief economist at data provider Markit, said: "Importantly, the upturn was not simply fueled by surging spending by households. Instead, exports and business investment were key drivers of the expansion, pointing to a rebalancing of the economy away from domestic consumption."
The Treasury, which is hoping a full-blown recovery is under way, after almost two years of weakness, seized on the widespread nature of recovery.
A spokeswoman said: "This data confirms that the British economy is moving from rescue to recovery, supported by balanced growth across the economy. It's particularly encouraging that growth in exports and investment contributed well over half of the second quarter growth rate. There is still a long way to go, but the economy is on the right track."
David Kern, of the British Chambers of Commerce, said: "Business investment is still too weak in spite of the modest rise, but the figures support our view that Britain's trading position is improving. Although the rebalancing towards net exports is taking some time, we have seen a significant narrowing of the trade deficit in the first half of this year."
