Another commenter mentioned it's more energy efficient to grow tomatoes in Spain - where less heat is needed - and fly them to the UK. That may be true, but an even better way is to just grow crops that are suitable for that season.
In the UK you can grow crops all year round outdoors [0], and the growing seasons could easily be extended with a passive greenhouse (polycarbonate is more insulating than glass). You can also use tried and tested preservation techniques like canning and fermenting to keep food for other seasons.
