According to the British Gas business energy market update, UK business energy costs have risen by 25% since February 2026, the largest increase in almost four years. Geopolitical uncertainty, strong summer cooling demand and lower-than-usual European gas storage could keep wholesale gas and electricity prices elevated into early 2027. Businesses approaching contract renewal may therefore face higher quotes and greater pressure on cash flow. Leaders should review contract end dates, compare fixed and flexible purchasing options, model the effect of further price rises and accelerate practical measures such as energy efficiency, demand management and on-site generation.

Government figures show that nearly 172,000 solar installations were completed across the UK in the first eight months of 2026, with the North West among the five leading regions. The figures point to sustained demand across homes, commercial property and larger-scale projects. This strengthens the case for reviewing on-site generation as part of longer-term energy-cost and resilience planning.
Companies anticipate almost $400 billion in future impacts from water-related disruption, yet many organisations still lack the processes needed to manage exposure across their supply chains. At site level, reliability-led engineering can cut methane leakage, water use and equipment failure without compromising production, while investment in flood defences and other adaptation measures could reduce UK climate losses by 30%. The message for leaders is clear: climate adaptation, water stewardship and asset reliability should be integrated into enterprise risk, capital planning and supplier assurance.

Climate action is increasingly being linked with energy security, national resilience and economic renewal. The UK has described climate and nature loss as a national security imperative, while calls for electricity market reform have intensified following analysis of gas-generation profits during the energy crisis. Prime Minister Andy Burnham has also presented net zero, community-owned energy and reindustrialisation as connected economic opportunities. For businesses, the direction of travel matters: regulatory, procurement and investment signals are increasingly likely to favour credible decarbonisation and resilience plans.
Great British Grid, a new publicly owned body within Great British Energy, will invest in electricity network infrastructure and work alongside existing operators to accelerate delivery. The government also plans to expand self-build connections, enabling eligible developers and businesses to construct their own links to the grid rather than wait for network companies. Faster connections could unlock clean-energy projects, industrial electrification and wider economic growth, although delivery timescales will be critical.
The government has announced £90 million for new and upgraded heat networks, including a major London scheme expected to unlock around £5 billion of investment and support up to 2,000 jobs. Heat networks can capture excess heat from factories and data centres and distribute it to homes and businesses, creating opportunities across engineering, construction, heat recovery, operations and maintenance. For commercial property owners and heat-intensive organisations, they may also provide a route to lower-carbon, more resilient heating.
A government consultation on modernising the UK corporate reporting framework proposes replacing many prescriptive strategic-report requirements with a smaller set of baseline disclosures. Explicit requirements covering environmental and other non-financial matters could be removed, although companies would still be expected to report issues that are financially material to their performance or operations. Alongside this, new EU anti-greenwashing rules applying from 27 September 2026 have significant implications for tourism businesses marketing to EU consumers. Hotels, tour operators and destinations must avoid vague or unsubstantiated claims such as “eco-friendly”, and must not use “carbon neutral” product claims based on emissions offsetting. Sustainability labels must be based on a recognised certification scheme or established by a public authority. Finance, legal, marketing and sustainability teams should review reporting processes, websites, brochures, advertising and social media together to reduce regulatory and reputational risk.

Great British Energy has launched £30 million for the first wave of its People’s Power programme, part of an anticipated investment of up to £1 billion supporting more than 1,000 local and community-led clean-energy projects. By working with local authorities and community groups to develop assets such as rooftop solar, wind and hydro schemes, businesses can help generate more power in the places where they operate. This creates opportunities for local installers, advisers, financiers and technology providers, while enabling businesses to build stronger local partnerships, retain more economic value within their area and improve their own long-term energy security.
From 2 November 2026, developers applying for consent for nationally significant infrastructure projects in England must deliver at least a 10% biodiversity net gain. The requirement will affect project design, land strategy, consenting, ecology, procurement and long-term habitat management. Developers should build biodiversity requirements into feasibility work and budgets early, while landowners and environmental-service providers may see greater demand for habitat creation, monitoring and off-site biodiversity units.
The latest developments reinforce a consistent message: sustainability, operational risk and growth should be considered together. Leaders should review exposure to climate and water disruption, plan early for grid connections and biodiversity requirements, assess emerging heat-network and community-energy opportunities, prepare for possible reporting changes, and ensure energy-storage and wider investment decisions remain commercially robust as policy evolves.
The organisations best placed to succeed will treat sustainability as part of strategy, risk and investment - not a parallel reporting exercise. The evidence from the past month suggests that markets are moving, technologies are scaling, legal expectations are widening and physical climate impacts are intensifying. Waiting for perfect certainty may now be the riskiest option. Consider your organisation's resilience by asking:
Green Economy helps businesses turn sustainability from a reporting requirement into a practical plan for growth, resilience and competitiveness.

If your organisation wants to build resilience, reduce emissions or understand where to start, speak to Green Economy about practical sustainability support tailored to your business.
Sustainability is increasingly important for business resilience because climate risks, energy costs, supply-chain expectations and customer requirements can all affect operations, profitability and growth. Businesses that understand these risks are better placed to plan investment, reduce disruption and respond to changing market conditions.
Climate change can affect workplace productivity through extreme heat, water stress, flooding, wildfire smoke and travel disruption. These conditions can make it harder for people to work safely and efficiently, particularly in operational sectors such as manufacturing, construction, logistics, food production and facilities management.
Scope 3 emissions are the indirect emissions linked to a company's value chain, including suppliers, transport, purchased goods, product use and disposal. They matter because customers, investors and procurement teams are increasingly asking businesses to understand and reduce emissions beyond their own direct operations. Green Economy's Scope 3 carbon reduction plan guide offers practical steps for getting started.
Businesses can start by identifying their biggest risks and opportunities, such as energy use, fleet emissions, supplier expectations, climate exposure and customer requirements. From there, they can prioritise actions that reduce costs, improve resilience, cut emissions and support long-term growth.
