Item 8.01 Other Events.

In addition to the Risk Factors contained in Item 1A of the Form 10-K for the fiscal year ended December 31, 2008, as amended by
Form 10-K/A Amendment No. 1, of UIL Holdings Corporation (the Registrant), the Registrant is hereby providing the following additional risk factor:

The current economic downturn has reduced the demand for electricity and has impaired the financial soundness of customers, which has adversely affected our results of operation and could continue to do so. The economic downturn could also impair the financial soundness of UI’s vendors and service providers.

The slowing of the Connecticut and national economies has resulted in reduced demand for electricity and could result in a continued reduction in such demand. In Connecticut, the economic slow-down has included a sustained decline in the housing market and rising unemployment. Connecticut’s unemployment rate rose from an average of 4.6% for 2007 to an average of 5.7% for 2008, close to the national average unemployment rate of 5.8%. However, Connecticut’s seasonally-adjusted unemployment rate increased to 7.5% in March 2009. Furthermore, as a result of the current economic downturn affecting the economies of the state of Connecticut, the United States and other parts of the world, UI’s vendors and service providers could experience serious cash flow problems. As a result, UI’s vendors and service providers may be unable to perform under existing contracts or may significantly increase their prices or reduce their output or performance on future contracts.
