Hi all,
I can remember a few years ago a crime prevention officer
mentioning so called deterrent bushes that you can place around your
garden or points of possible entry - not doors :-)

As well as the plants mentioned by the others it's probably worth
getting in touch with your local police, most forces have leaflets
with lists of suitable plants for your area, and some list sources as
well.
Thanks to everyone for their help.
Cheers,
Keith
