                       BOARD RETIREMENT AND APPOINTMENT


Halma p.l.c., the leading safety, health and sensor technology group, today
announces the forthcoming retirement of Keith Roy as an Executive Director and
the appointment of Adam Meyers to the Board.

Keith Roy, 57, has given notice that he will retire and resign as a Director
with effect from 31 July 2008.  In accordance with Halma's internal succession
planning processes and to ensure a smooth handover, Adam Meyers will be
appointed as an Executive Director with immediate effect.

Adam Meyers, 46, has been a member of Halma's Executive Board since April 2003
as the Divisional Chief Executive responsible for the Fluid Technology Division
within Halma's Health and Analysis sector.  Prior to that, he was an Assistant
Divisional Chief Executive and President of Bio-Chem Valve, having joined the
Group in 1996.  He is a graduate of the University of Pennsylvania and has an
MBA from Harvard Business School.

Geoff Unwin, Halma's Chairman, commented:

'I would like to record my thanks to Keith Roy who has made a tremendous
contribution to the success of Halma since he sold his business to the group in
1993.  Amongst his many achievements, Keith has been unceasing in his efforts to
develop talent throughout the organisation.  The value of this is clearly seen
by the increase in internal promotions in recent years, particularly at Halma
Executive Board level.

'We welcome Adam Meyers to the Halma Board.  In his 11 years with the group,
Adam has built a strong track record of achievement contributing both consistent
organic growth and acquisitions to our success.  His knowledge of many of our
Health and Analysis markets, particularly in the US, will bring an added
dimension to the Board.'
