The analysis comes after the six named storms which hit the UK last winter, including Bert and Connall, which led to severe flooding in parts of England in November 2024.
The Met Office has also stated that winters were getting wetter, with six of the 10 wettest recorded half-winters between October and March happening since 2000.
Floods Minister Emma Hardy said the government had redirected £108m into repairs and the maintenance of defences nationally, and would spend £10.5bn in the next decade, including building new ones.
The EA’s repair programme for defences it directly manages remains ongoing after it redirected £72m to maintaining flood assets.
An EA spokesperson said protecting communities was more important as climate change brought more extreme weather.
“If the performance of an asset is reduced, then immediate action is taken to ensure that flood risk continues to be effectively managed until the asset is fully repaired or replaced,” they added.
