Britain's economy grew at 0.2% for the second quarter, according to the first revision of the data by the Office for National Statistics (ONS).
This is despite the ONS downgrading its figures for second quarter industrial production growth, from -1.4% to -1.6%.
The ONS attributed the figure to growth in the service and construction sectors.
Ahead of the first official revision, markets had predicted the data would remain unchanged.
The FTSE has remained down following the announcement, declining 0.54% or 28 points to 5,103. The pound is up 0.15% against the dollar to $1.63.
The Bank of England is confident GDP growth will pick up during the second half of the year to reach the government's target of 1.7%.
It said stronger growth will be underpinned by a steady recovery in business investment and a gradual rebalancing of the economy towards external demand.
"Although the fiscal consolidation is likely to dampen activity throughout the forecast period, consumer spending growth should slowly increase as the drag on real income growth from high inflation dissipates," the Bank said.
