We have had a lot of enquiries regarding whether we sell and deliver compost and unfortunately we do not. However there is a composting centre near us, Stanmer Composting Centre, who do sell compost. If you want to order compost please email them on firstname.lastname@example.org and give them your name, number, address and how much compost you need. They deliver both organic and non-organic compost. They will deliver to you, delivery time is currently 3-5 day wait. You will need to order a minimum of 10 x 35litre bags.
Good luck with growing!
