WWOOF UK holds a list of organic farms, gardens and smallholdings, all offering food and accommodation in exchange for practical help on their land. These hosts range from a low impact woodland settlement to a 600 hectare mixed holding with on-site farm shop, cafe and education centre. Hosts do not expect you to know a lot about farming when you arrive, but they do expect you to be willing to learn and able to fit in with their lifestyle.
Volunteers do not pay to stay with hosts and hosts do not pay volunteers for their help (generally 25-30 hours a week). WWOOFers are volunteers and therefore are more free to come and go than an employee. For this reason, hosts should not depend on them as an alternative to paid, skilled labour.
