Halma PLC

                                Halma p.l.c.

                              TRADING UPDATE

Halma, the leading safety and environmental technology group, issued a trading
update today, 28 October 2004.  Halma issues trading updates each October and
April, ahead of its interim and full year announcements.  Halma's interim
results for the six months to 2 October 2004 will be announced on 7 December
2004.

Halma remains ungeared even though the Group has fully funded in cash two
significant acquisitions and has made a record dividend payment during the
period.

The first half results are expected to be within the range of the Board's
expectations.  As advised in Halma's full year announcement in June and again at
the Group's Annual General Meeting in August, the weakness of the US dollar has
affected the first half results but the ongoing weakness in the dollar is
expected to have a reduced impact in the second half of the current financial
year.

In the first six months, the Group's Water and Resistor sectors continued to
experience difficult conditions and the Elevator and Door Safety sector is not
expected to match the prior period's record result.  However, as anticipated,
the two recently announced acquisitions have been immediately earnings enhancing
and their contribution to profits is expected to be greater in the second half.
