The UK government has pledged £4.2 billion ($8.72 billion) over three years to “build and maintain flood defences” – but the insurance industry wants more.

The funding, aimed at “protecting communities from the dangers of flooding”, was announced in yesterday’s spending review.

The Association of British Insurers has welcomed the move but calls for clarity over the long-term plan.

“We know the devastating impact flooding has on communities across the country,” director general Hannah Gurga said.

“The funding marked for flood defences … is a welcome step towards climate adaptation, but to build real, lasting resilience it must sit within a clear, long-term framework.  

“We want to see this outlined in the forthcoming 10-year infrastructure strategy.”

The UK’s flood reinsurance pool, Flood Re, which is scheduled to end in 2039, has also praised the government’s commitment to tackling the issue.

“With one in four homes at risk of flooding, the UK faces one of its greatest climate change challenges,” chair Bridget Rosewell said.

“The important thing now is ensuring the funding is employed effectively to support the UK’s insurability going forward. The consultation on how the funding is spent is a welcome opportunity to focus efforts on resilience, maintenance and innovation.”

But she says infrastructure alone will not solve the problem.

“Most flooding occurs at depths of less than 15cm and households can take cost-effective steps such as installing non-return valves and self-closing airbricks. Outdoor spaces also offer opportunities for flood prevention, helping capture water before it enters the home and repurposing it for garden irrigation.

“In partnership with insurers, we continue to expand initiatives like Build Back Better, which help households recover more resiliently. But this needs to be matched by greater public engagement and a step change in how we adapt to future risk.”
