The number of start-up firms registering at the Companies Office rose 11 per cent in July compared to the same month last year. There were some 1,518 start-ups during the month, according to figures from credit and business risk analysis company Vision-net.ie. The company said this was the highest number for the month of July since pre-recession 2007.

The professional services sector was the most popular industry, accounting for 22 per cent of new companies, followed by wholesale and retail, which accounted for 10 per cent. Construction businesses are now third most popular, with 9 per cent.

"July's company start-up figures are the highest seen in that month in seven years and are indicative of greater business confidence," said Christine Cullen, managing director of Vision-net.ie.
