Take the eastern exit off the A36 at Codford, opposite the Stockton turn. Turn immediately right when you have left the A36, signposted Malmpit Hill, with a no through road sign. Follow this road up the hill past four houses. Bear left at the brow, onto the private access road. Follow this road up the steep hill then along the top of the farm for 2 miles. Codford Biogas is next to the road on the right.
