Britain's economy grew an estimated 0.8 per cent in the three months to the end of November but has not yet reached pre-recession levels, the National Institute of Economic and Social Research (NIESR) said on Tuesday.
The figure represents a slight increase from the 0.7 per cent reached in the three months to October.
The economic think tank said that continued growth in a wide range of sectors was supporting the recovery, and the pace of expansion was consistent with a "gradual narrowing of the UK's negative output gap".
Separate data from the Office of National Statistics earlier showed that British industrial output rose by 0.4 per cent in October, slightly above a Reuters poll consensus of 0.3 per cent.
The ONS also said that the overall trade deficit narrowed in the same month to £2.62 billion ($5.21 billion), including a surplus in trade in services.
