EXHIBIT 31.2

                                  CERTIFICATION


I, Louis J. Paglia, certify that:

1.  I have reviewed this quarterly report on Form 10-Q of UIL
    Holdings Corporation;

2.  Based on my knowledge, this report does not contain any untrue
    statement of a material fact or omit to state a material fact
    necessary to make the statements made, in light of the
    circumstances under which such statements were made, not
    misleading with respect to the period covered by this report;

3.  Based on my knowledge, the financial statements, and other
    financial information included in this report, fairly present
    in all material respects the financial condition, results of
    operations and cash flows of the registrant as of, and for,
    the periods presented in this report;

4.  The registrant's other certifying officer and I are
    responsible for establishing and maintaining disclosure
    controls and procedures (as defined in Exchange Act Rules
    13a-15(e) and 15d-15(e)) for the registrant and have:

     a)  Designed such disclosure controls and procedures, or caused
         such disclosure controls and procedures to be designed under
         our supervision, to ensure that material information relating
         to the registrant, including its consolidated subsidiaries, is
         made known to us by others within those entities, particularly
         during the period in which this report is being prepared;

     b)  Evaluated the effectiveness of the registrant's disclosure
         controls and procedures and presented in this report our
         conclusions about the effectiveness of the disclosure controls
         and procedures, as of the end of the period covered by this
         report based on such evaluation; and

     c)  Disclosed in this report any change in the registrant's
         internal control over financial reporting that occurred during
         the registrant's most recent fiscal quarter (the registrant's
         fourth fiscal quarter in the case of an annual report) that
         has materially affected, or is reasonably likely to materially
         affect, the registrant's internal control over financial
         reporting; and

5.  The registrant's other certifying officer and I have
    disclosed, based on our most recent evaluation of internal
    control over financial reporting, to the registrant's auditors
    and the audit committee of the registrant's board of directors
    (or persons performing the equivalent functions):

     a)  All significant deficiencies and material weaknesses in the
         design or operation of internal control over financial
         reporting which are reasonably likely to adversely affect the
         registrant's ability to record, process, summarize and report
         financial information; and

     b)  Any fraud, whether or not material, that involves management
         or other employees who have a significant role in the
         registrant's internal control over financial reporting.
