The Crown Estate owns the territorial seabed out to 12 nautical miles and around half of the foreshore around England, Wales and Northern Ireland.
Hand harvesting of seaweed for any form of monetary or other reward from Crown foreshore or seabed will require a licence from The Crown Estate. The granting of the licence will be dependent upon relevant natural heritage authority (Natural England in most cases) confirmation of the sustainability of the harvesting proposal. Please visit our Seaweed Harvesting page for more information on the process for licensing.
Collection for personal use does not require a licence and we are content for such collection to proceed for small quantities. We recommend anyone doing so takes account of environmental sensitivity of collecting anything from the wild.
