                                TRADING UPDATE                                

Halma, the leading safety and environmental technology Group, issued a trading
statement today, 26 April 2001.  Halma issues trading updates each April and
October, two months ahead of its full year and interim announcements.

The Group continues to make good progress and it is anticipated that results
for the year to 31 March 2001 will be in line with market expectations. 
Halma's preliminary results will be announced on 19 June 2001.

The benefits arising from the reorganisation of the Group's businesses into
six product-related groupings have continued to underpin operating
performance.  Organic growth, supplemented by successful acquisitions made
over the last two years, has led to particularly good performances being
reported by the Resistor and the Fire and Gas businesses.

The acquisitions of Wessex Electronics and Fire Fighting Enterprises have
further strengthened Halma's electronics technology capabilities in the growth
areas of water leak reduction and fire detection.  The integration of both
businesses is progressing well.

Halma is confident of maintaining its track record of strong cash flow and
high return on capital, supporting the Group's strategy of maximising
self-funded growth.
