The upward revision of 0.1 per cent will nevertheless provide a small boost to the new Coalition government, which faces the daunting task of toning up the UK's finances.
Howard Archer, chief UK economist at IHS Global Insight said of the figures: "This in itself is not overly worrying as overall growth in the first quarter was clearly dragged down appreciably by the very bad weather in January, and most indicators suggest that the recovery has firmed to a limited extent since then."
This figure could yet rise further if services growth, which was left unchanged at 0.2 per cent following bad winter weather, moves higher – as has been the case in previous quarters.
However, Archer pointed out that net trade was “very disappointingly negative” for a third successive quarter and sliced 0.4 percentage point off first quarter GDP growth as imports rose by 1.4 per cent quarter-on-quarter but exports were flat despite the weakened pound.
Economists warn that growth is now likely to remain subdued with high unemployment and looming fiscal tightening likely to weigh on consumer spending while the the Eurozone crisis threatens to dampen UK growth by limiting exports and knocking confidence.
Jonathan Loynes, chief European economist, says: “Overall, a pretty weak picture. With household spending flat, growth was therefore driven by government spending, inventories and investment. The first two won’t last much longer.
“We continue to expect growth of just one per cent or so in 2010 overall, picking up only slightly to 1.5 per cent in 2011.”
Mark Bolsom, head of the UK Trading Desk at Travelex Global Business Payments, added: “With a daunting level of national debt, rising inflation and low interest rates, I don’t think the economy will grow much past one per cent this year.
"The real crux of whether we're going to carry on growing depends on the extent to which the forthcoming austerity measures contract the economy. UK economic growth will be determined by events on the 22 June."
