With foreign travel just opening up and only a handful of countries making the green list, staycations are on the cards for a lot of Brits this summer. But not all holidays live up to expectations, and some coastal trips can be let down by smelly water, littered sand and run-down towns. With this in mind, SaveOnEnergy.com/uk set out to find Britain’s beaches with the cleanest, or filthiest, water.

To do this, they investigated levels of faecal indicators (E. Coli (EC) and Intestinal Enterococci (IE)) in the ocean, as tested yearly by the government, to find which beaches are best for a paddle and which are best left alone. They analysed data from 546 beaches around England, Scotland and Wales, giving them a ranking from 0 (dirtiest) to 100 (cleanest).
