Like-for-like growth at Britain's largest pub group Enterprise Inns accelerated to 2.1% in the third quarter but it said the first five weeks of the fourth quarter were flat against tough comparatives.The FTSE-250 constituent said a 1.3% rise in like-for-like net income for the 44 weeks to August was in line with its own expectations, driven by the Fifa World Cup in the third quarter.The start to the fourth quarter took a slight dip with like-for-like net income dropping to 1.5%. Enterprise said this was due to a more "challenging and comparative period".Chief executive officer Simon Townsend said: "The final quarter of the year will be measured against tougher comparatives but we are encouraged by the start we have made and remain comfortable with our full year expectations."He said management continued to direct an increased proportion of capital investment toward initiatives to grow income.The group said cash flow and balance sheet metrics were in line with expectations and that it expected to meet full year guidance of net proceeds from asset disposals of £70m which will be used to fund its capital investment programme. Enterprise also added it anticipates total net debt will be reduced to £2.4bn by the end of 2014.
