Letter from Karen Dunnell, dated 26 April 21007:
As National Statistician, I have been asked to reply to your recent parliamentary question asking the percentage that employers' national insurance contributions form of the UK labour cost. (133588)
Estimates of the various components of labour costs are provided by the ONS in its labour costs survey (LCS). LCS estimates are compiled every four years based on information from the annual survey of hours and earnings, labour force survey, annual business inquiry and other data sources. The most recent results were compiled for 2004 and cover sectors C-O of the UK standard industrial classification of economic activities 2003 and businesses with 10 or more employees. The 2004 LCS shows that the proportion of UK labour costs attributable to employers' national insurance contributions is 6.2 per cent.
