you dont have a clue how expensive it is, or not, because you've not got a quote for any other companies.
You're absolutely right, I don't have a clue. Most of our business is with Openfield.
I merely stated that the implied risk of failure was greater than I had supposed it to be before Openfield themselves drew the whole matter to public attention.
To be fair, however, most of the 50p/tonne will be in various layers of brokers' fees and commissions, and reinsurance, and the actuarial risk of failure probably well under 5p.
