Are we being fleeced in GB.

Look at price and availability via a Google search and figure it out. If
you just ask some "marine fire protection" outfit to change out your
extinguishers then you probably are getting thoroughly fleeced.

What kind of arrangement do you have on a 34 footer that needs FM200?
Will a fixed CO2 system or more handhelds work just as well for you in
your boat?

If they are charging you a small fortune to "dispose" of the old Halon,
try and find a recycler who may pay you for it instead. It is still OK
to use in certain applications in the UK and most of the rest of the
world. If nothing else just stash it somewhere until it is more
valuable, the rest of the world has another 6 or 7 years to use it and
its value will increase for a while.
