Can anyone give me some clues about thatcham approved security
clobber? Am I
correct in thinking that it needs to be installed by a
thatcham approved bod
as well as the kit itself being thatcham approved?

That is right. Plus it also has to be checked annually by a VSIB
approved fitter to retain it's Thatcham approved status.

Has anyone any experience
of how much impact they make on insurance premiums, and the
likelihood of
the car being nicked?

It could make a considerable difference. Having a Thatcham
approved alarm fitted, reduced a friends Cosworth premium by
over £500.

Obviously it wouldn't stop someone who really wanted the car,
but it would almost certainly prevent any yobo from just taking
your car for a drive.
Wouldn't necessarily stop them from smashing the window or door
lock though.
