British families now have more cash to spend after tax than before the Coalition came to power , official figures revealed this morning . The boost , just 37 days before the election , came as separate figures showed that Britain 's economy grew faster than any other major rich country in the world last year . People 's confidence in their own finances also jumped to complete a 'hat trick of good news ' for David Cameron and George Osborne this morning . Scroll down for video . In the final three months of the year , families had £4,187 to spend or save – finally overtaking the £4,187 families had left over at the time of the last election . Britain 's economy grew faster than any other major rich country in the world last year , official figures revealed this morning . The Office for National Statistics said the UK economy grew 0.6 per cent in the last three months of the year – 0.1 per cent more than previously thought . But over the whole of 2014 , the economy boomed by 2.8 per cent – faster than America , Germany , France and every other country in the G7 group of rich countries . Mr Osborne said the revised figures show the UK is 'clearly fastest growing major advanced economy ' in the world . Separate figures released this morning revealed that in the final three months of the year , the average voter had £4,187 left over after tax , up 1.8 per cent on the previous quarter . Mr Osborne said this meant that living standards were now officially higher than at the last election , when real disposable income was £4,187 . The Chancellor said : 'Today we 've got a hat-trick of good news about the British economy and with 37 days to go the election it 's another sign that changing course would put recovery at risk . ' The Chancellor George Osborne , pictured at a Pizza Express restaurant in Hove this morning , claimed the economic figures were a triple dose of good news . David Cameron was out campaigning at a building site at Sainsbury 's head office in Holborn , central London , this morning . The Office for National Statistics said the economy grew 0.6 per cent in the last three months of the year – 0.1 per cent more than previously thought . He added : 'We 've had a significant upgrade to GDP , the highest consumer confidence for over 12 years and confirmation that living standards are higher than they were at the last election . 'This is good news for families and businesses across the country . 'So voters now face a stark choice : do we stick with a plan which is working , delivering growth and jobs , or do we put all that at risk with Ed Miliband whose policies of more spending , more borrowing and higher taxes will lead to economic chaos . ' GDP per head – the wealth of each Briton rather than the economy as a whole – was also estimated to have increased in the last three months of the year – jumping by a healthy 0.5 per cent . Lib Dem Treasury Secretary Danny Alexander added : 'As we approach the General Election , this upward revision in GDP is further evidence that our recovery plan is working . ' But the shadow chancellor Ed Balls said Tory claims that the economy was fixed would 'ring hollow with working people ' . He said : ' A small upward revision today in the GDP figures does n't change that overall record . This has been a disappointing recovery and it did n't have to be this way . 'If the Conservatives want to go round and say 'Our plan is working , look at the GDP figures ; our plan is working , look at the figures on disposable income ' then we say bring it on because the reality is that this is the toughest squeeze on people 's living standards in a parliament since the early 1920s . ' He added : ' I do n't think that just crossing your fingers and hoping for the best is good enough . '
