Logically it's your land so do what you want, if you don't sign the paper and collect the money they have no legal powers to make you do anything as you have no contract with them, that's the one big plus about going it alone.This is a very good point.
@Janet Hughes Defra without BPS how will you ensure minimum environmental standards (cross compliance) are upheld for all those who don't sign up to the new schemes e.g hedge/water course buffers?
Seems a major issue to me and it's hard to see how it can practically be enforced. Will there be new legislation and will non compliances go through the courts?
On the other hand we can expect legislation to be put in place to prevent all that in spite of that "bonfire of red tape"
