Is the quality of our sustainable products derived from agriculture recognized and valued by British consumers? Will it be possible to continue exporting Spanish organic products after Brexit without obstacles? With this research, we seek to improve scientific knowledge on how British consumers perceive and value sustainable products from the Spanish agricultural sector, as well as possible barriers that may be encountered, providing useful and valuable information for Spanish agricultural companies. In line with this, the results obtained can be used to improve or adapt the design of marketing and communication strategies in this market, which is in continuous growth and dynamism.
