Peter Jones, one of the UK’s most high-profile SME investors, has warned that bad businesses would be saved from collapse if the economy was suddenly flooded with credit.

His concerns raise the possibility that the economic downturn could be extended as struggling companies with bad business models stave off collapse, through extended credit, only to fail further down the line.

The Dragons’ Den star said it was vital to the prosperity of the UK’s 4.7m SME companies that access to finance was carefully controlled.

“Of course we want the approval of credit to speed up a bit,” said Jones, currently championing Small Business Week 2009, which is backed by BT Business.

“We want credit to start flowing a little bit faster than it is but if you open up the doors and credit opens up too fast, all that’s going to happen is the businesses that are going to be saved, on occasion, will be businesses that probably do not deserve to be around.”

Jones’ comments echo those of restructuring experts who have warned the government to avoid giving emergency funders in CVAs super priority status, because bad management could waste creditors’ cash on unrealistic rescue plans before collapsing.

“We’ve just got carried away on the self-fulfilling cycle of increased debt and let’s be perfectly honest, we’ve gone from hero to zero in the last six months,” Jones added.

“Business doesn’t survive without credit. But we can’t ‘freefall’ ourselves back into the position of opening the doors and letting the credit flow again.”

Jones took the tough line as companies condemn the continuing lack of credit despite government handouts to ailing banks after their subprime woes.

“Are banks lending enough money? No they’re not,” said Jones. “But they’re doing exactly what we would expect any normal business person to do: be cautious.”

Kevin Dickens, chair of accountants’ body the UK200Group, said Jones’ comments were “incredibly controversial”. He added: “There are good companies finding it hard to get credit at the moment, so the bad businesses will find it even more difficult.”

Federation of Small Businesses spokesman Stephen Alambritis said: “We agree with Peter Jones. We’ve always said we shouldn’t be throwing good money after businesses that are badly run.”
