Over 5,000 construction companies, and over 3,500 manufacturing companies, have been declared insolvent since September 2010, reveals PriceWaterhouseCoopers.

There have been 9,113 insolvencies in construction and manufacturing since September of 2010, figures from PwC reveal, despite the two sectors enjoying one of the best quarters in nearly two years.

From April to June 2012 there were 15.5% fewer insolvencies in construction than the previous quarter, and nearly 8.36% fewer in manufacturing. But where most regions enjoyed a relatively good quarter, London lost 66 manufacturing firms – the biggest rise in any UK region at 50%.

London suffered 120 construction insolvencies in Q2, and has lost 962 firms overall since September 2010. Most regions again enjoyed a slightly better quarter, with Yorkshire, the West and East regions faring better.

In the West Midlands there were 54 manufacturing insolvencies for Q2 this year, compared to 83 in Q1 of this year – about 35% fewer.

Of the 5,527 construction companies declared insolvent, approximately 30% (1,635) were general construction and civil engineering firms, with the remainder made up of architectural, building, water projects, painting, roofing and plastering firms.

Across all sectors there were 11% fewer insolvencies this quarter than the previous one, but under the ongoing cloud of economic and unemployment uncertainty, PwC experts say the slight reprieve in figures may not signal a long term improvement, with the same pressures continuing through to 2013.
