These are excellent schemes, aimed (unusually rather successfully, I think) at improving standards in UK agriculture.
We used a grant of this type to help us refurbish our cubicle shed last year. Without the grant we would have taken longer and, whilst we would have ended up with comfortable cattle, we would not have had such good facilities and would certainly not have bought mattresses (I kid you not.) Having got them with the grant's help, I would certainly make a case to any farmer for the additional spend.
I've been told that it was lucky we went for the refurbishment when we did, as the new scheme would not cover what we did.
