Every parliamentary constituency in Great Britain is expected to face heightened flood risk in the coming decades, according to a new study by the insurance company Aviva, media reports said on Wednesday.

The company analyzed all constituencies in the UK, Wales, and Scotland to assess vulnerability to river and coastal flooding, according to the Guardian.

The results showed that in the UK alone, 69% of constituencies are projected to see more than a 25% rise in the number of properties at risk by mid-century.

In Wales and Scotland, all areas are expected to experience similar increases, with some potentially facing even steeper surges.

The risk is especially acute in densely populated and low-lying areas.

In Bermondsey and Old Southwark in the British capital London, as well as Boston and Skegness in Lincolnshire, about 90% of properties could face flood risk by 2050.

The Guardian quoted Aviva’s UK and Ireland general insurance chief executive Jason Storah as saying: “We’re not in this because we’re climate campaigners or trying to burnish our credentials or because we have a political agenda. This is a hard-headed calculation; we’re looking at the numbers.”

Former Environment Agency chair Emma Boyd told the newspaper that some flood-prone areas may eventually become too expensive to protect, warning that “one more flood could bankrupt” towns like Tenbury Wells in Worcestershire, where insurers have already withdrawn coverage.

Matthew Taylor, one of the reporters behind the Guardian investigation, said the concern from insurers is widespread: “It is absolutely a sign that the climate crisis is here and escalating in the UK.”

The UK’s joint government-industry program Flood Re, which currently protects individual properties, is scheduled to end in 2039.

Business and public properties are not covered under this scheme.

Taylor added: “The reality is that some areas at some point will just become too prohibitively expensive to protect and then get flooded too much for them to get insurance, and that is pretty stark.”

Long-term strategies, new investment plan

In response to mounting concerns, UK Floods Minister Emma Hardy recently announced a £10.5 billion ($12.9 billion) investment plan to protect 900,000 properties across the UK.

The initiative includes new measures aimed at accelerating flood defense construction.

The government said it is also developing long-term strategies to improve London's flood infrastructure over the next century, as well as looking into broader solutions such as natural flood management.

However, critics fear that the government's parallel commitment to build 1.5 million new homes by the end of the current parliament will jeopardize climate resilience.

“Within that drive for planning reform, there needs to be an absolute recognition that we need to protect new properties and communities,” Taylor said.

Experts and campaigners emphasize the importance of individual preparation in addition to government action.

The Guardian's report emphasized community-level strategies like sealing entry points, removing pavement to improve drainage, and advocating for better flood protection.

Taylor acknowledged that climate reporting can feel overwhelming but said he finds hope in grassroots movements.

“When people see an injustice, they come together and make a difference,” he said.

He also stressed that solutions already exist: “We already have all the answers and the technologies we need to address the crisis—we just need the political will.”
