Trend watch: Flood, drought & wildfire resilience in 2026 — signals, winners, and red flags

The first two months of 2026 have already delivered a record-breaking sequence of compound weather events across the United Kingdom: Storm Eowyn caused an estimated GBP 1.2 billion in damages across England and Wales in January, while Scotland recorded its driest February since 1993. Simultaneously, wildfire risk alerts were issued for Welsh moorlands and the Scottish Highlands weeks earlier than historical norms. These events are not anomalies. They represent the accelerating convergence of flood, drought, and wildfire hazards that the UK Climate Change Committee's 2025 Independent Assessment warned would define the decade ahead.

Why It Matters

The UK faces a compounding resilience challenge that the traditional siloed approach to hazard management is no longer equipped to address. The Environment Agency estimates that 5.2 million properties in England alone are at risk from flooding, a figure that will increase by 30-50% under medium emissions scenarios by 2050. The Met Office's UK Climate Projections (UKCP18) confirmed that summer rainfall will decline by 20-40% in southern England by the 2060s, intensifying agricultural drought stress during growing seasons. Wildfire incidents recorded by UK fire services increased 58% between 2019 and 2025, driven by hotter, drier summers and expanded wildland-urban interface zones.

The financial stakes are escalating rapidly. Insured losses from UK weather events exceeded GBP 4.8 billion in 2025, according to the Association of British Insurers (ABI). Flood Re, the joint government-industry reinsurance scheme established in 2016, processed claims from 18,000 properties in 2025 alone, a 34% increase from 2024. The scheme is scheduled for review in 2029, and growing evidence suggests that its current premium structure underprices risk for properties in the highest flood zones.

The regulatory environment is shifting in response. The Flood and Water Management Act amendments expected in 2026 will expand mandatory sustainable drainage systems (SuDS) requirements to all new developments. The Environment Act 2021 biodiversity net gain provisions, now fully operational, intersect with flood resilience through requirements for nature-based solutions. The Financial Conduct Authority's climate disclosure rules, aligned with ISSB standards, require listed companies and regulated financial services firms to report physical climate risk exposures, including flood, drought, and wildfire scenarios.

Key Signals to Watch

Signal 1: Compound Event Modelling Reaches Operational Maturity

The most consequential technical development in UK resilience planning is the shift from single-hazard to compound-event modelling. The Met Office's joint probability framework, developed in collaboration with the Centre for Ecology and Hydrology, now enables local authorities to assess the likelihood of sequential or simultaneous flood-drought events. For example, the summer 2025 sequence in East Anglia, where severe drought followed by intense rainfall on hardened soils caused flash flooding 40% more severe than rainfall volume alone would predict, is now reproducible in planning models.

JBA Risk Management launched its UK Multi-Peril platform in late 2025, integrating flood, subsidence, and wildfire risk layers for every postcode in England, Scotland, and Wales. Early adopters among insurers report that compound risk scores exceed the sum of individual hazard scores by 15-30% for properties in transitional climate zones, particularly the East Midlands and eastern Scotland.

Signal 2: Nature-Based Solutions Move from Pilot to Portfolio Scale

The UK government's GBP 5.2 billion flood defence programme (2021-2027) has progressively allocated funding toward nature-based solutions, reaching 22% of programme spend in 2025-2026. The Yorkshire Integrated Catchment Solutions Programme (iCASP) demonstrated that upstream natural flood management, including floodplain reconnection, leaky dams, and strategic tree planting, reduced peak flows by 15-20% in tributary catchments at a cost 40-60% below traditional hard engineering.

The Somerset Levels resilience programme, integrating wetland restoration with controlled winter flooding and summer water retention, now serves as the national template for dual flood-drought management. The programme stored an estimated 12 million cubic metres of water during winter 2025, which buffered agricultural water supply during the drier spring months. This dual-purpose approach addresses the fundamental tension between flood drainage and drought preparedness that has constrained UK water management for decades.

Signal 3: Wildfire Risk Enters UK Planning Policy

Wildfire has historically been treated as a marginal risk in UK planning. That assumption is changing. The Saddleworth Moor fire of 2018, the Wareham Forest fire of 2020, and the London grass fires during July 2022's record heat event collectively demonstrated that wildfire poses genuine threat to UK communities and infrastructure. The Wildfire Framework for England, published in 2025, establishes the first national risk assessment methodology, identifies 340 communities in the wildland-urban interface requiring enhanced planning controls, and mandates vegetation management zones around new developments in identified risk areas.

Scottish Natural Heritage data shows that the area burned annually in Scotland has increased threefold since 2010, correlating strongly with reduced summer precipitation and extended fire weather indices. The Scottish Government's draft Wildfire Strategy, expected for consultation in mid-2026, will propose statutory responsibilities for landowners regarding fire risk management on estates exceeding 100 hectares.

Emerging Winners

Parametric Insurance Products

Traditional indemnity insurance is struggling with the frequency and severity of compound weather events. Parametric products, which pay predetermined amounts when specified triggers are met (rainfall exceeding a threshold, river levels breaching a gauge, or fire weather indices crossing defined values), are filling the gap. FloodFlash, a UK-based parametric flood insurance provider, grew its commercial client base by 280% in 2025 and now covers over GBP 2 billion in property value. The company's sensor-based trigger system pays claims within 48 hours, compared to weeks or months for traditional loss adjusting.

Descartes Underwriting, operating across UK agricultural and commercial sectors, offers parametric drought cover tied to soil moisture satellite data from the Copernicus Land Monitoring Service. Payouts trigger automatically when soil moisture drops below contract thresholds, eliminating the subjective assessment that delays traditional agricultural insurance claims.

Remote Sensing and Early Warning Platforms

Satellite and IoT-based monitoring is transforming hazard detection from reactive to predictive. Previsico, a Loughborough University spinout, provides real-time surface water flood forecasting at 10-metre resolution, enabling 6-24 hour advance warnings for specific properties. The platform processed alerts for 22,000 UK properties during Storm Eowyn, with 87% accuracy for flood depth predictions within 10 centimetres.

SatSense uses satellite InSAR data to detect ground movement precursors to subsidence, a drought-related peril that cost UK insurers GBP 320 million in 2025. Their monitoring covers 4.2 million properties across southern and eastern England, alerting homeowners and insurers to subsidence risk before cracks appear.

Resilience-as-a-Service Consultancies

A new generation of consultancies is aggregating climate analytics, engineering design, and financing into integrated resilience offerings. Arup's Climate Risk and Resilience practice grew its UK team by 45% in 2025. Mott MacDonald's Adapt platform combines physical risk modelling with economic analysis to produce investment-grade resilience business cases for local authorities. WSP's Climate Risk Adaptation practice now serves over 60 UK local authorities with place-based resilience strategies.

Red Flags

Maintenance Deficit in Existing Flood Infrastructure

The Environment Agency's State of the Nation infrastructure report (2025) revealed that 16% of flood defence assets in England are in "poor" or "very poor" condition, up from 11% in 2020. The maintenance backlog now exceeds GBP 860 million. Several high-profile defence failures during winter 2025-2026 were attributed to deferred maintenance rather than design inadequacy. Practitioners should scrutinise local maintenance budgets and condition assessments rather than relying solely on the existence of flood defences as evidence of protection.

Insurance Retreat from High-Risk Zones

While Flood Re provides residential coverage, commercial properties, new developments, and properties built after 2009 fall outside its scope. Evidence from the ABI indicates that 14% of commercial properties in Flood Zone 3 (high risk) were unable to obtain affordable flood insurance in 2025, up from 8% in 2022. The trend toward insurance retreat, where premiums become unaffordable or coverage becomes unavailable, risks creating "uninsurable" zones that undermine property values and economic viability.

Greenwashing Nature-Based Solutions Claims

As funding flows toward nature-based solutions, evidence of inflated performance claims is growing. A 2025 review by the Rivers Trust found that 30% of natural flood management schemes assessed had insufficient monitoring data to verify claimed benefits. Several schemes promoted as providing "significant" flood risk reduction had monitoring periods of less than two years, insufficient to capture meaningful storm events. The lack of standardised monitoring protocols creates space for overstatement, particularly from developers seeking biodiversity net gain credits alongside flood resilience claims.

Drought Preparedness Remains Fragmented

Despite the Water Resources Planning Guideline updates in 2025, regional water companies continue to operate largely independent drought management strategies. The proposed Strategic Resource Options, including inter-regional transfers, new reservoirs, and desalination capacity, remain 8-15 years from operational delivery. The 2025 dry spring exposed supply vulnerabilities in Thames Water and Southern Water regions that existing plans had not adequately stress-tested. Practitioners dependent on reliable water supply should assess their regional water company's drought resilience independently of published supply forecasts.

Action Checklist

• Assess property and portfolio exposure using compound multi-hazard risk models rather than single-peril flood maps
• Review insurance coverage for gaps related to drought subsidence, wildfire, and commercial flood exclusions
• Evaluate nature-based solutions claims against independently monitored performance data with multi-year records
• Engage with local authority resilience strategies and participate in catchment-level partnership programmes
• Incorporate wildfire risk into site assessments for rural, peri-urban, and moorland-adjacent properties
• Stress-test water supply assumptions against realistic drought scenarios, particularly for operations in southern and eastern England
• Monitor Flood Re review developments and assess potential premium implications for residential portfolios
• Establish parametric insurance triggers for time-critical operations where rapid payout is more valuable than indemnity assessment
