Item 4.        Changes In Registrant's Certifying Accountant

On October 15, 1998,  Ernst & Young ("Ernst & Young")  informed  Saville Systems
PLC (the  "Registrant")  that it was resigning as the  Registrant's  independent
auditors and  principal  accountants.  The reason given by Ernst & Young for its
resignation was the existence of certain mutual business  opportunities on which
both Ernst & Young and the Registrant desire to collaborate which affect Ernst &
Young's  independence with respect to the Registrant.  Ernst & Young's report on
Saville's  financial  statements during the two most recent fiscal years and all
subsequent  interim  periods  preceding  the date  hereof  contained  no adverse
opinion or a disclaimer of opinions,  and was not  qualified as to  uncertainty,
audit scope or  accounting  principles.  The  decision to accept Ernst & Young's
resignation was made by the Board of Directors of the Registrant.

During the Registrant's two most recent fiscal years and the subsequent  interim
period  immediately  preceding the date of the resignation of Ernst & Young, the
Registrant had no  disagreements  with Ernst & Young on any matter of accounting
principles or practices,  financial  statement  disclosure or auditing  scope or
procedure, which disagreement(s), if not resolved to the satisfaction of Ernst &
Young, would have caused Ernst & Young to make a reference to the subject matter
of the  disagreement  in connection  with its reports.  None of the  "reportable
events"  listed in Item 304 (a) (1) (ii) of Regulation  S-K under the Securities
Exchange Act of 1934 occurred with respect to the Registrant within the last two
fiscal years and the subsequent interim period to the date hereof.

The  Registrant  has  requested  that  Ernst & Young  furnish  it with a  letter
addressed to the  Commission  stating  whether it agrees with the statements set
forth above. A copy of this letter is filed as Exhibit 16 to this Current Report
on Form 8-K.

Effective  October  22,  1998,  the  Registrant  engaged  PricewaterhouseCoopers
("PwC") as its principal accountants and independent auditors to replace Ernst &
Young.  The  decision  to engage PwC was made by the Board of  Directors  of the
Registrant.  During the last two fiscal years and the subsequent  interim period
to the date hereof,  neither the Registrant  nor anyone on its behalf  consulted
PwC regarding the application of accounting  principles to a specific  completed
or contemplated transaction, or the type of audit opinion that might be rendered
on  the  Registrant's  Financial  statements,  and no  written  or  oral  advice
concerning the same was provided to the Registrant that was an important  factor
considered  by the  Registrant  in  reaching  a decision  as to any  accounting,
auditing or financial reporting issue.
