Cities in the West Midlands are among areas where businesses have reported strong sales growth in recent years, a new study has shown.

Firms in Wolverhampton and Birmingham reported sales growth of at least 10% in the past two years compared with before the recession, said services company Experian.

An analysis of accounts from 150,000 businesses between 2008 and 2011 showed that nine out of 10 areas with the biggest increases in businesses reporting strong sales growth were in the Midlands or North.

Max Firth of Experian said: “Many of the towns and cities highlighted as showing the biggest improvements in sales growth were widely believed to be struggling during the period analysed.

“Places like Stoke-on-Trent, Hull, Wolverhampton and Birmingham are incubating some strong businesses that have demonstrated the ability to grow significantly, even in the tough economic climate that existed between 2010 and 2011.

“If businesses such as these can be nurtured to sustain their growth, it should lead to improved prosperity for those areas.”
