The Forum of Private Business (FPB) has called on banks to provide restaurant insurance holders with access to finance.
According to the organisation, some financial institutions could be refusing restaurant insurance customers loans because of fears over their business viability.
The group claimed that some lenders are denying loans to restaurant insurance holders point blank, rather than assessing each case on an individual basis.
Noel Guilford, national chairman of the FPB, commented: "We have evidence that banks are taking a negative blanket approach to this sector which is directly against what the government is saying they should do."
Mr Guilford also called for the government to intervene on the matter to prevent restaurant insurance holders from having to make further job cuts, saying that the behaviour of some banks is "disgraceful".
Earlier this month, Bob Cotton, chief executive of the Restaurant Association, claimed that hospitality firms have to adapt to changing customer demands created by the recession.
