A: If your parish or local council’s allotment authority wants to sell an allotment site, it must have the consent of the Secretary of State. The allotment authority must also fulfill certain conditions including consultation with plotholders.

If the application is successful, the allotment authority has to provide an alternative site. If an allotment authority ends a tenancy, the plot holder is entitled to compensation.

If your allotment is temporary or on privately owned land, then the Secretary of State's consent is not required but the allotment authority will usually need to give you 12 months' notice to quit.
