Trading Statement

Halma PLC
26 October 2006


                                  Halma p.l.c.

                            HALF YEAR TRADING UPDATE

Halma's trading performance for the first six months of the year is expected to
be at the top end of the Board's expectations and we are continuing to achieve
healthy organic growth.  The Board remains positive about the Group's prospects
for the full year.

All three sectors will report increased revenues and profit for the first half
year.

Infrastructure Sensors is now delivering organic profit growth from the revenue
growth momentum which started to emerge in the second half of last year.  In
particular, our Automatic Door Sensor business, BEA, is performing well.

Health and Analysis is making solid progress with our Photonics business
continuing to grow strongly.

Industrial Safety is growing organically across all business areas, each of
which has benefited from the buoyant energy markets.

Acquisition activity continues.  In September 2006, Halma acquired assets
associated with sample handling and conditioning equipment for industrial
emissions monitoring and process control applications from Baldwin Environmental
Inc. for an initial consideration of $1.1m.  This acquisition brings additional
fluid sample drying technology and products to one of our existing Fluid
Technology businesses, Perma Pure, based in New Jersey, USA.  Up to a further
$700,000 is payable dependent upon net revenue growth for the period to March
2009.

The Group's Interim Results will be released on 5 December 2006.
