UK launches £1 billion FloodAction Coalition to turn natural flood management into investable asset class

Friday, 14 November 2025 5:04AM UTC

The UK government's new FloodAction Coalition aims to mobilise over £1 billion by 2028, harnessing private-sector innovation and nature-based solutions to transform flood and drought resilience into a sustainable, investable asset class, signalling a shift in climate adaptation strategies.

The UK government is embarking on a significant drive to bolster the nation's resilience to flooding through a combination of public investment and private-sector innovation. Central to this effort is the recently unveiled FloodAction Coalition, a market-led partnership launched in London by Emma Reynolds, the UK secretary of state for environment, food and rural affairs, alongside leaders from insurers, landowners, water utilities, and environmental groups. The coalition aims to transform climate resilience, particularly natural flood and drought management, into a viable and investable asset class with ambitions to mobilise over £1 billion by 2028.

Flooding and drought represent some of the fastest-growing and most costly climate risks in the UK. According to insurance giant Aviva, whose chief sustainability officer Claudine Blamey spoke on the coalition’s launch, these climate events now pose systemic risks to property, transport infrastructure, and farmland. Industry data illustrates the scale of exposure: 5.7 million UK properties and a third of critical infrastructure are already at risk, with projections suggesting one in four homes in England could be at flood risk by 2050.

The FloodAction Coalition positions itself as a multi-sector alliance that includes The Conduit, Aviva, major landowners such as The Crown Estate and the National Trust, NGOs, water utilities like Anglian Water, and government agencies. It seeks to develop the UK's first investment market dedicated to nature-based flood and drought resilience. By unlocking both private and public capital, the coalition aims to build large-scale portfolios of projects that use natural flood management (NFM) techniques, such as wetland restoration, woodland planting, and soil health improvements, to reduce flood peaks and store water during dry spells.

This approach is reportedly cost-effective and scalable. Pilot studies in the UK have shown that these nature-based interventions can reduce peak flood flows by between 10 and 30 percent, often at roughly half the cost of traditional engineered defences. Moreover, they provide co-benefits including carbon storage, improved biodiversity, and better water quality. One example cited comes from Norfolk, where a nature-based project achieved a 17-to-1 return on investment in terms of risk reduction.

Kevin Arnold, executive vice chairman at UBS, emphasised the potential of natural flood management to emerge alongside renewable energy and sustainable infrastructure as a mainstream financial product. He outlined a vision of “stackable cashflows” from resilience projects, insurance savings, carbon credits, and biodiversity gains that would make such investments both financially attractive and environmentally impactful.

The government is backing this vision through a series of policy reforms and funding commitments. The Department for Environment, Food and Rural Affairs (DEFRA) announced record investments in flood resilience, including a commitment to invest over £300 million in natural flood management over the next decade, the highest level to date. These reforms also introduce measures designed to increase investor confidence by treating refurbishment of existing flood defences on par with new constructions, thereby encouraging maintenance and extending the life of critical infrastructure.

Further government initiatives include a £2.65 billion two-year programme to build or maintain up to 1,000 flood defences, targeting enhanced protection for more than 66,000 properties across England. Additionally, £25 million is being allocated specifically to nature-based flood management projects, supporting around 40 initiatives focused on wetlands, tree planting, and other natural interventions. Complementary funding is directed towards internal drainage boards to support farmers and rural communities, acknowledging the vital role these groups play in managing water levels and flood risks.

Industry leaders from Anglian Water and National Highways have expressed strong support for the coalition, viewing it as an opportunity to shift away from reliance on traditional “grey” infrastructure towards nature-based solutions that can be delivered faster and at greater scale. This marks a significant shift in flood risk strategy, aligning with broader environmental goals.

Despite the clear benefits and strong backing, questions remain about whether natural flood management can be fully transformed into a credible, sustainable asset class. The FloodAction Coalition’s task is not only to develop projects but to create the financial structures that will attract long-term investment, blending public and private capital to de-risk early-stage projects and deepen market participation.

If successful, this initiative could establish a replicable model for climate resilience infrastructure that delivers measurable financial, social, and environmental returns. It would represent a watershed moment in how the UK, and potentially other countries, tackle the escalating threats of flooding and drought in an era of climate change.
