From 1 February 2010, British farmers will be eligible for unsecured, interest-free loans for between £3,000 and £20,000 to help them upgrade to more energy-efficient equipment. The loans are designed to pay for themselves through direct energy savings provided over one to four years – and after the loan is repaid, farmers will make direct savings on their energy costs, as well as cutting the carbon footprint of what they produce.
