The UK government's Environment Agency has outlined the next tranche of what it describes as the largest flood defence programme in English history, allocating £1.4 billion for 2026/27 across more than 600 projects ranging from engineered barriers to nature-based water management schemes. The funding forms part of a broader commitment of at least £10.5 billion between 2024 and 2036 to reduce flood and coastal erosion risk to homes, businesses and critical infrastructure across England. Alongside new construction, £260 million has been set aside specifically for the repair and maintenance of existing Environment Agency assets — including defences damaged during recent storm events — in what officials say marks a reversal of more than a decade of declining asset condition.
The economic case
Central to the programme's justification is a cost-benefit ratio that will resonate with water sector professionals worldwide: every £1 spent on flood defences is estimated to prevent approximately £8 in economic damage. On that basis, the 2026/27 allocation alone is projected to shield the English economy from upwards of £10 billion in losses.
We're combining engineering and nature-based solutions to reduce flood risk and build long-term resilience for communities across the country
Over the next decade, a projected £7.9 billion in construction investment is expected to benefit around 840,000 properties.
Engineering meets ecology
What distinguishes this programme from conventional hard-infrastructure approaches is its explicit integration of nature-based solutions alongside traditional flood engineering. The Environment Agency has outlined plans to expand natural flood management (NFM) techniques — including river re-naturalisation, tree planting and saltmarsh restoration — to intercept and slow water movement before it reaches populated areas.
One example cited is the work of Ribble Rivers Trust in Lancashire, where landowners are being supported to install leaky barriers, timber structures designed to reduce flow velocity, alongside floodplain wetland restoration, reducing flood exposure to the town of Clitheroe while generating ecological co-benefits.
Caroline Douglass, Environment Agency Executive Director for Flood and Coastal Risk Management, described the approach: "From major flood barriers and strengthened embankments to natural flood management and coastal defence projects, we're combining engineering and nature-based solutions to reduce flood risk and build long-term resilience for communities across the country."
Selected schemes
Among the larger capital projects receiving 2026/27 allocations:
- Bridgwater Tidal Barrier, Somerset — £59.3 million, protecting against river flooding in a low-lying coastal zone
- Derby Flood Risk Management Scheme — £37.1 million for phase two of a programme on the River Derwent, safeguarding around 1,500 homes and 700 businesses, as well as critical industrial infrastructure
- Kendal, Cumbria — £24.3 million addressing river flood risk in a town with a well-documented history of severe inundation
- Pevensey Bay to Eastbourne coastal scheme — Over £8 million this year as part of a £100 million long-term coastal defence programme protecting more than 3,100 properties
