Local Government Minister John Healey has laid regulations before Parliament that enable authorities to postpone any possible budgetary impact of this until 2010-11.
Without this help, they would have to make immediate provision for possible losses in their revenue budgets - with potentially serious impacts on council tax or services.
New statistics published today show that as at the end of last year, 125 local authorities in England had outstanding investments of around £923.2million in Icelandic banks.
John Healey said:
"Following the failure of Icelandic banks last year the Government - with the Local Government Association - acted immediately to ensure no local authority faced serious short term difficulty as a result. We continue to work closely with the banks and Icelandic authorities to help local authorities and other creditors recover their money.
"This money isn't lost but it is at risk so under normal financial rules this risk would need to be taken into account in their budgets. I was concerned about the possible, and potentially unnecessary, effect this could have on services and council tax. That's why I am taking this exceptional step that gives authorities some breathing space that should allow them to be clearer what sums, if any, are still at risk. Meanwhile the Government will continue its efforts to ensure that investors recover as much as possible from the banks."
The regulations come into force on 31 March 2009 and apply immediately.
