Updated 6 December 2023

Applies to England

These results summarise the compliance of coastal and inland bathing waters for England in 2021. Datasets on compliance for coastal and inland bathing waters in England are available to download

1. Headline results

  • In 2021, out of the 417 bathing waters measured in England, 413 (99.0 per cent) met at least the minimum standard of the Bathing Water Regulations.

  • In 2021, 295 bathing waters in England (70.7 per cent) met the Excellent standard of the Bathing Water Regulations.

  • In 2021, 4 bathing waters in England (1.0 per cent) did not meet the minimum standard, and were classified as Poor.

2. Context

For every designated bathing water in England, the Environment Agency monitors Escherichia coli and intestinal enterococci in the water, throughout the bathing season (15 May to 30 September). Values can vary; depending on the weather, pollution from agricultural and urban sources, storm water overflows, amongst other factors. The readings taken over the last four bathing seasons then determine the annual classification for that water. Due to Coronavirus restrictions during the 2020 bathing water season, there was no classification in 2020. The 2021 classification results cover the period from 2017 to 2021; over a five year period, while still maintaining only the last four bathing seasons (namely 2017, 2018, 2019 and 2021).

Three bathing waters were de-designated prior to the 2021 season, with one new water being designated. A further two bathing waters are unassessed due to access issues.

The classifications are:

  • Excellent – the highest, cleanest class
  • Good – generally good water quality
  • Sufficient – the water quality meets the minimum standard
  • Poor – the water quality has not met the minimum standard.
