ITEM 4. CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANT. On June 6, 2002, Integrated Electrical Services, Inc. ("IES" or the "Company") dismissed Arthur Andersen LLP ("Andersen") as its principal accountant and engaged Ernst & Young LLP ("E&Y") as its principal accountant. The decision to change principal accountants was recommended by the Audit Committee and was approved by the Board of Directors of the Company. The change will be effective immediately. Andersen's reports on the consolidated financial statements of the Company for the past two fiscal years did not contain an adverse opinion or a disclaimer of opinion, nor were such reports qualified or modified as to uncertainty, audit scope, or accounting principles. During the past two fiscal years and through the date of this Current Report, there have been no disagreements with Andersen on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to the satisfaction of Andersen, would have caused it to make reference to the subject matter in connection with its reports on the Company's consolidated financial statements for such years, nor have there been any reportable events as listed in Item 304 (a) (1) (v) of Regulation S-K. Andersen was provided with a copy of the statements made in the foregoing paragraph and has furnished a letter addressed to the Commission stating that it agrees with such statements. A copy of Andersen's letter dated June 6, 2002 is attached hereto as Exhibit 16.1. A copy of the press release issued by the Company regarding its change in accountants is attached hereto as Exhibit 99.1 ITEM 7. FINANCIAL STATEMENTS AND EXHIBITS.

(NYSE: IES) today announced that its Board of Directors has appointed Ernst & Young LLP as the Company's independent auditors for fiscal year 2002.

"I would like to thank the firm of Arthur Andersen for its service," said Roddy Allen, president and chief executive officer. "Arthur Andersen has served our company admirably and the individuals who've worked on our account have always displayed the highest level of professionalism. However, the events and uncertainty surrounding Arthur Andersen and its future have necessitated this action, which we believe is in the best interests of the company and its shareholders."
