River Thames set to get its first official bathing site as water quality improves

The government has proposed 13 new designated bathing sites, including a stretch of the River Thames at Ham and Kingston that could become London's first river bathing site; designation brings regular water quality testing and public information on safety.

London's River Thames has been included in a government proposal to add 13 new designated bathing sites across England, which would make a stretch at Ham and Kingston the capital's first official river bathing location. The move is presented as part of a longer-term improvement in water quality; the Thames was described as biologically dead in the 1950s and has since seen gradual recovery. Designation means sites will be monitored and information on water quality will be published. The government also says it has reformed monitoring rules and widened the legal definition of "bather" to include water-sport participants. Key facts: - The proposal covers 13 new sites across England, from Northumberland to Cornwall and Yorkshire, and includes the River Thames at Ham and Kingston. - If designated, England's total number of official bathing sites would rise to 464 beaches, coastal stretches, rivers and lakes. - Designated status requires regular water quality testing and public reporting on safety for swimming, paddling and water sports. - The government has adjusted monitoring dates to better match when people use sites and expanded the legal definition of "bather" to include paddle boarders and surfers. - In 2025, 87% of designated bathing sites were rated excellent or good, 93% met at least the minimum standard, and 7% (32 sites) failed to meet minimum standards. Summary: Officials describe the Thames inclusion as a significant milestone in long-term water-quality improvements, with designation intended to provide clearer information about safety for recreational users. The 13 proposed sites have been published for consultation, and local communities and campaigners say the move could increase pressure for further river and coastal clean-up.
