Not sure how much it would cost in the UK, but here in middle America you can buy large quantities of gardening soil quite cheaply. I ordered 3 cubic yards from a nursery for US$180 delivered (literally a dump truck / tipper lorry put it in my driveway). The same amount of soil from the local big box garden center would have cost almost US$1000 and I would be responsible for getting it home. Get your neighbors together and get one delivery for maximum savings!
