As climate impacts intensify, businesses across the UK are waking up to a new reality: resilience is no longer a sideline concern. It is fast becoming a defining feature of economic success. But for many, the scale and nature of the threat remains poorly understood. Climate change is not a distant environmental challenge; it is a present, systemic force reshaping markets, undermining productivity, and exposing the fragility of assets, operations, and supply chains.
Are businesses underestimating climate risk?
The UK’s climate is already changing. Annual temperatures are rising, heavy rainfall is becoming more intense, and drought conditions (expected this summer) are emerging with greater frequency. Yet business and investor responses remain partial and slow. Risk assessments still often rely on historical data, ignoring the acceleration and non-linearity of future threats. Heatwaves are no longer rare. In 2022, the UK recorded its first 40°C day. Yet most workplace health and safety guidance still assumes such temperatures are extreme outliers.
Meanwhile, many companies are failing to factor physical climate risks into long-term decisions. Property portfolios may face rapid devaluation as flood risk increases. Agricultural yields are being hit by erratic rainfall and soil degradation. Water-intensive sectors, from food & drink to manufacturing, are operating in catchments where water stress is now a material constraint. Across the board, climate-related disruptions are rising, but disclosure and preparation are not keeping pace.
The rising tide: heat, flood and drought risks
Of the many climate-related risks, three are especially acute for the UK business environment: heat, flood, and drought.
Heat affects both infrastructure and people. Overheating buildings compromise indoor air quality and reduce productivity. In manual and outdoor labour, heat stress poses direct health risks, especially for workers in construction, logistics, agriculture and public services. Yet most businesses have no heat resilience strategy, no dynamic working policies, and little awareness of how heat might affect absenteeism, insurance, or operating hours.
Flooding is becoming more frequent and less predictable. Surface water and fluvial flooding already cost the UK billions annually, and damage to commercial premises, transport, and energy infrastructure has cascading economic impacts. As storm systems intensify, critical national infrastructure - particularly in coastal and riverine areas - is under threat.
Drought and water scarcity are often overlooked in a country known for rain, but the evidence is mounting. By 2050, the UK could face water supply shortfalls of over 4 billion litres per day. For industries reliant on clean water, such as breweries, food processors, tech manufacturers, this is an existential risk. Moreover, as rivers shrink and temperatures rise, water quality deteriorates, threatening not just human health but ecosystems, fisheries, and tourism.
Nature-based solutions: a scalable defence and opportunity
One of the most powerful, yet underused, tools for managing these risks is nature itself. Nature-based solutions (NbS) offer a way to reduce climate vulnerability while delivering co-benefits for biodiversity, carbon sequestration, and wellbeing.
To manage flood risk, restoring wetlands, reconnecting rivers to floodplains, and reforesting uplands slows runoff and stores water naturally. These systems not only protect downstream infrastructure but recharge aquifers and improve water quality.
For drought resilience, restoring peatlands and woodlands helps retain moisture in the landscape, cool the air, and improve soil structure. In urban areas, green infrastructure like parks, swales, and green roofs helps moderate temperature and store stormwater.
When it comes to heat resilience, trees and vegetation reduce the urban heat island effect, cool public spaces, and improve worker comfort. Studies show that shaded environments can lower ambient temperatures by several degrees, crucial as extreme heat events grow more frequent.
On water quality, NbS like buffer strips, constructed wetlands, and catchment-scale restoration trap sediments, filter pollutants, and reduce agricultural runoff, making them a cost-effective alternative to grey infrastructure.
These are not speculative ideas. They are proven, cost-effective, and increasingly investable. Yet they are often underfunded, undervalued, and disconnected from mainstream infrastructure planning.
Adaptation as opportunity: new markets, new business models
If climate resilience is a challenge, it is also a growth frontier. Around the world, demand is rising for adaptation services, resilient infrastructure, nature-based solutions, and climate intelligence tools. Businesses that can pivot toward these emerging markets will be well-positioned in the decades ahead.
Just looking at the UK alone, opportunities include:
Resilient design and retrofitting: Heat-resilient buildings, green roofs, sustainable drainage systems, and passive cooling are in growing demand across public and private sectors.
Water innovation: From leak detection and smart irrigation to water reuse and ecosystem-based purification, the technology and service ecosystem around water resilience is expanding fast.
Climate analytics: High-resolution data and modelling tools, especially those integrating ecological vulnerability, are in demand from insurers, developers, local authorities and corporates.
Nature-based infrastructure: There is growing interest from investors in green assets that deliver measurable flood protection, carbon storage, and biodiversity uplift. Markets for biodiversity net gain, carbon credits, and ecosystem services are nascent but growing. We can also secure our food system.
The UK’s moment to lead
The UK has the potential to become a global leader in climate adaptation - if it acts decisively. It already possesses world-class research institutions (like the Met Office, Oxford’s ECI, CISL, Exeter’s GSI, CEH and numerous others), a globally influential insurance sector, and emerging policy frameworks on biodiversity net gain and nature markets. What’s missing is scale, coordination, and consistent political support.
Leadership will require:
Embedding NbS in national infrastructure strategies alongside grey engineering approaches, and recognising their long-term value through public procurement and planning reform.
Stronger mandates and incentives for businesses to disclose and address physical climate risks, aligned with the Taskforce on Climate-related Financial Disclosures (TCFD) and the ISSB.
Public investment and blended finance to unlock early-stage NbS projects and build a pipeline of investable natural assets.
A workforce resilience strategy, integrating climate risk into occupational health, green skills training, and employment law.
Regional climate and nature hubs, offering practical support to SMEs and local authorities to embed NbS and resilience planning into place-based economic development.
Protecting workers to protect productivity
Perhaps the most under-addressed aspect of business resilience is the workforce. Climate change is not an abstract backdrop - rather it directly affects the people whose labour sustains the economy. Heat stress, disrupted commutes, mental health strain from climate disasters, and increased absenteeism all degrade performance. But few firms have mapped these risks, let alone implemented strategies to mitigate them.
Leading organisations are beginning to act: adjusting shift patterns during hot weather, upgrading uniforms and PPE, investing in green infrastructure around workspaces, and training employees to understand and respond to climate hazards. But these examples are still rare. Protecting workers must become core to any serious adaptation strategy, not just out of duty, but because resilience and productivity go hand in hand. A caring employer also happens to be a successful employer!
Conclusion: from risk to resilience to regeneration
The climate crisis is not a future risk - it is a present force reshaping how we live, work, and do business. For UK firms, the choice is stark: wait for disruption or plan for resilience. The most forward-looking businesses will not only protect themselves, but unlock new growth by investing in the infrastructure, skills, and ecosystems that adaptation demands. Nature-based solutions should be central to this shift, not just for their climate value, but for the regenerative economy they make possible. The UK, with its capacity for innovation, regulation, and finance, has a unique opportunity to lead. But leadership will require a shift in mindset: from minimising harm to maximising resilience; from reacting to shaping; and from risk to regeneration. It’s all within our gift.
