The species present in the waters tend to be those that aren't dangerous to humans, such as basking sharks.
But, marine biologist Ryan Johnston believes that this could all change because global warming continues to disrupt eco-systems.
Johnston, one of the experts appearing on National Geographic's SharkFest season – which jumpstarted on Sunday (17 July) – encourages British shark fans to "keep their eyes peeled" because "sooner or later" Great Whites could be on the horizon.
"The theory that a lot of people are working with is that, as climate change comes, warmer waters are going to reach up into the UK.
"Because there is a great white population in the Mediterranean and around Spain, that population will be able to extend up to English waters," he said.
According to Ladbible, a fin that people believed to be from a Great White was seen off the coast of Goring-by-Sea, West Sussex, having been photographed 30 miles away from another sighting off Hayling Island, Hampshire, all back in 2017.
Great Whites can reach up to 20ft in length and weigh 5,000lbs. They can also live for 70 years.
