拢254m-turnover David McLean is pushed under by 拢100m debts, joining 拢131m-turnover Taggart

The collapse of two 拢100m-plus turnover housebuilders this month shows that medium-sized companies are no longer safe, industry sources have warned.

The claim follows the demise this week of housebuilder and contractor David McLean which had a reported turnover of 拢254m and Northern Ireland group Taggart Holdings last week, which turned over 鈧164m (拢131m) in 2006.

According to figures from the Home Builders Federation, David McLean was the UK鈥檚 30th largest housebuilder by turnover in 2007 and Taggart was number 33. Both were ahead of listed companies Telford Homes (35) and Oakdene (72).

David McLean, which is based in Flintshire and employs 320 staff, became the biggest construction casualty of the credit crunch after it collapsed with up to 拢100m of debt.

According to one source, it was pushed under by a mixture of the weak housing market and 鈥渙ne or two problem contracts鈥 in its contracting arm. Its contracting business, David McLean Contractors, will close; administrator Deloitte is seeking a buyer for the 拢124m-turnover housebuilding division.

Meanwhile, a source familiar with Taggart said it had paid the price for growing too quickly and building on unviable sites. Administrator Pricewaterhouse Coopers refused to confirm reports that the company has debts of about 拢150m.

Robin Hardy, an analyst at KBC Peel Hunt, said: 鈥淭his is a wake-up call for the small and medium-sized guys that the banks will play hardball if they think they can get their money back. This is different to the last recession because there is not the resource of mortgage availability to fall back on.鈥

Another financial source predicted several more companies of a similar size would go bust in coming months. But he said the credibility of a company鈥檚 management team should not be underestimated as a factor in the banks鈥 thinking.

鈥淎 big part of the decision on whether to pull the plug is based on whether they believe in the management team. They are tending to support companies where everything is transparent and above-board.鈥
