Water quality at the UK’s bathing spots is falling significantly behind some neighbouring countries in Europe, analysis by NationalWorld can reveal.

As water companies continue to pump raw sewage into some of the country’s most popular swimming spots, figures suggest that the issue may be largely isolated to the UK.

Across much of Europe bathing waters recorded much higher standards than those found in the UK, data published by the European Environment Agency (EEA) and UK equivalents reveal.

Environment watchdogs monitor bathing spots such as coastal waters, lakes and rivers and classify the standard under excellent, good, sufficient or poor.

NationalWorld analysed ratings data for more than 21,000 European Union (EU) and 600 UK bathing sites, finding the proportion rated less than excellent in the UK was more than double that of Europe – 31.9%, versus just 12.5% on the continent.

We excluded around 700 European sites which had not been given a rating.

So how do swimming spots in England, Scotland, Northern Ireland and Wales compare with those at popular holiday destinations in Spain, France and Italy? These four charts will show you how the quality of bathing sites varies across the continent.

What do bathing water ratings mean?

The Environment Agency, which monitors bathing sites in England, tests for bacteria (E.coli and intestinal enterococci) throughout the summer season. The readings taken over the last four bathing seasons then determine the annual classification for the site.

The Agency said ratings can vary depending on the weather, pollution from agricultural and urban sources and storm water overflows.

An excellent rating is the highest/cleanest classification, good means generally good water quality, sufficient means the minimum standard has been met and poor means the water has not met the quality standard.

When there is poor water quality swimmers are advised against bathing. The government publishes daily information on water quality at bathing sites in England.

Similarly, the EU Bathing Waters Directive requires country’s to monitor microbiological pollution (and other substances) at bathing spots throughout the summer season.

Scotland had the greatest proportion of bathing sites classified as less than excellent in 2021, with almost two-thirds (62.4%) or 52 bathing spots falling into the category. Only one site in Scotland was found to be in a poor condition however  –  Dhoon Bay in Dumfries and Galloway.
