Campaigners Demand Bathing Water Rule Reform After Henley Thames Bid Fails
Campaigners in Henley are urging the government to overhaul England's bathing water regulations, following the rejection of a stretch of the River Thames for official bathing water status. They argue that a narrow definition of "bathers" has excluded many river users, hindering efforts to improve water quality and protect public health.
Narrow Definition Excludes River Users
In a letter to Environment Secretary Emma Reynolds, local businesses, river users, community groups, and civic leaders highlighted that poor water quality has damaged the town and posed health risks. The application for bathing water status for the Thames stretch used in the annual rowing regatta was turned down because Defra's criteria only consider "bathers," excluding those who engage in organised swimming events, rowing, kayaking, paddleboarding, or sailing.
Jo Robb, a member of the Henley Mermaids swimming group, described a catch-22 situation: "We cannot improve water quality without bathing water designation, but we cannot achieve designation because water quality is too poor to attract bathers." She called the current system "fundamentally flawed and not fit for purpose."
Impact on Local Events and Economy
Swimming events in Henley were cancelled last year due to declining entries linked to water quality concerns, affecting local businesses. Jonathan Hobbs of Hobbs of Henley boat hire service stated, "My business, like many in Henley, depends on a clean river for its survival. It's absurd that England's premier river town cannot qualify for bathing water status under the current rules, leaving us with no way of cleaning up our stretch of river."
The groups are advocating for several changes, including expanding the definition of "bathers" to encompass all recreational water users.
Water Quality and Public Health Concerns
Water quality in the River Thames at Henley consistently fails to meet safe limits for swimming. Citizen-led testing by Health on the Thames Water (HoT Water) has recorded elevated levels of E coli. In 2025, tests found E coli levels up to 10 times the safe limit, averaging 2,922 CFU per 100ml during the bathing season from 15 May to 30 September. The Environment Agency's limit for "sufficient" quality is 900 CFU per 100ml, with "excellent" quality requiring less than 250 CFU per 100ml.
Dave Wallace, lead at HoT Water, warned, "These levels pose a threat to anyone entering the water, but especially to children and those with existing health conditions. Our data is clear: the River Thames in Henley is a threat to public health."
Political Context and Government Response
Water company sewage pollution is expected to be a key issue in the upcoming local elections in May. While Labour has resisted calls to renationalise the industry and not moved to place Thames Water under temporary public ownership, the Green party manifesto supports returning water companies to public ownership, calling privatisation a "failed experiment."
A government spokesperson responded, "The government is taking decisive action to clean up the nation's rivers, lakes, and seas so communities across the country can enjoy the places they care about most. We are reforming regulations to better reflect how people actually use their local rivers, lakes and beaches, and are exploring expanding the definition of bathers to include participants in other water sports." They noted that an evidence review is underway to assess the environmental and public health implications of such changes.
Bathing water designation would mandate regular testing for fecal contamination and could enforce additional treatments to enhance water quality, offering a potential solution to Henley's ongoing challenges.
