AFAIK they haven't been used for quite some time, though I don't know
the exact year they were phased out (I'll ask on Pistonheads, there are
quite a few Trafic Police that regularly post there).

They were replaced by Laser based guns as they were more robust and more
immune to false readings.  They also aquire a "lock" much more quickly,
typicaly in well under a second.  The radar devices could take several
seconds, and a radar detector could give you enough warning to slow down
if you were over the limit, but laser detectors are a complete waste of
money.  If it alerts you then you can be expecting an NIP in the post
shortly.
