Following the release of the National Energy System Operator’s Whole Energy Market Strategy (WEMS) UK industries and markets have been digesting what this means for their finances and future.
The questions on everyone’s mind: Who will fund these net zero initiatives? What will it do to energy bills and operating costs? And can the transition also spark economic opportunity?
Graham Paul, Service Delivery Director at TEAM energy unpacks the funding challenges surrounding net zero, examines the potential impact on business energy costs, and explores how a strategically managed transition could unlock new opportunities for UK industries and the wider economy.
Market concerns about funding net zero
Industries are deeply concerned about how the investment in net zero will be financed and who ultimately pays. Achieving UK climate targets is capital intensive from upgrading infrastructure and building renewables, to electrifying transport and retrofitting buildings. There is broad agreement that a mix of public and private funding is needed, but the distribution of costs is a contentious issue.
Government funding and policy support
- The UK government is ramping up its commitment to net zero. The 2025 Spending Review allocated tens of billions to clean energy and low-carbon infrastructure including £14.2 billion for a new nuclear plant, £9.4 billion for carbon capture, and £13.2 billion to continue the Warm Homes efficiency programme. These investments are designed to spark private sector momentum, with the Treasury emphasising that public funds should “mobilise private investment” in domestic clean energy.
- Policy shifts are also helping reduce costs for emerging technologies. For example, removing levies on green hydrogen production is making it more commercially viable. Funding tools include direct grants, low-interest green loans, government guarantees, contracts-for-difference, and regulatory incentives all aimed at sharing upfront costs across taxpayers, energy users, and investors.
Cost concerns for businesses and consumers
- A key concern is the extent to which net zero costs will be passed on to energy bills. Businesses and consumers worry about hidden charges from green levies or mandated investments. While public debate has stirred fears, some claims are overstated social and environmental levies make up around 11–16% of a typical household bill, not the 25% some suggest. Even the April 2025 price cap rise was only 10% driven by green policy costs.
- These levies fund renewables and schemes like the Warm Homes Discount investments, not just added costs. Still, industrial users remain uneasy: if funding gaps emerge, could levies rise or new carbon taxes be introduced?
Capital availability and private investment
- Private investment is essential for net zero, but many UK firms face funding hurdles. A Mitie study found 78% of sustainability leaders struggle to secure capital for decarbonisation projects like heat pumps and onsite renewables. This bottleneck underscores the need for strong government backing.
- Despite over 80% of businesses expressing confidence in meeting net zero goals, lack of capital remains a top barrier alongside energy costs and supply issues. Many are calling for innovative financing solutions, including green bonds and public-private partnerships, to close the investment gap.
Balancing supply vs. demand funding
- The WEMS report revealed a major funding imbalance: £39 billion is committed to clean energy supply, but just £3 billion to demand-side measures that help consumers and businesses adopt low-carbon tech. This mismatch raises concerns energy producers worry about low uptake, while end-users lack support to afford new solutions.
- Bridging this gap is key. More funding for demand like grants for electric heating, vehicles, and retrofits could boost business confidence and ensure a market for clean energy. Policymakers are now asking: what’s the right balance to drive a successful net zero transition?
Energy costs: rising bills vs. long term savings
Net zero investments raise a key question for businesses: how will they affect energy bills? In the short term, costs and volatility are a concern but in the long run, clean energy and efficiency offer savings and stability.
Current pressures
UK firms face high and unpredictable energy prices, worsened by global gas market turmoil. A January 2025 survey found 57% of sustainability leaders fear rising costs, and 64% worry about ongoing volatility. With inflation squeezing budgets, 86% cite cost as the biggest barrier to climate action. Many have slowed or revised net zero plans to stay afloat.
Near term impacts
Some decarbonisation measures add short-term costs like compliance with energy standards or carbon pricing under the UK ETS. Upfront spending on renewables or EVs can be steep, but government incentives (grants, tax breaks) are helping. Businesses that plan ahead through audits, phased upgrades, and smart procurement can manage costs gradually.
Long term benefits
Most net zero investments lead to lower operating costs over time. Oxford’s Smith School found 80% of low-carbon upgrades (solar, EVs, heat pumps) reduce lifetime costs. Efficient electric tech cuts fuel and maintenance expenses, while renewables offer free energy once installed. Long term contracts or self-generation also shield businesses from future price spikes.
The cost of delay
Inaction carries its own price. Delaying net zero leaves firms exposed to fossil fuel shocks, carbon taxes, and climate disruptions. Studies suggest doing nothing could cost the UK 3.3% of GDP by 2050 triple the annual investment needed now. For businesses, investing in sustainability is not just ethical it’s financial risk management.
Opportunities for the UK economy and businesses
Despite concerns over cost, net zero is a major growth engine for the UK creating jobs, boosting productivity, and opening new markets.
A booming green economy
In 2024, the UK’s net zero economy grew 10%, reaching £83 billion in GVA outpacing sectors like agriculture and advertising. It now contributes 1.1% of total output and supports millions of high-skilled, high-paid jobs. Workers in green industries are 38% more productive than the UK average. Growth is spread across regions, helping level up local economies and strengthen energy security by reducing reliance on fossil fuel imports.
Business innovation and competitive edge
Sustainability is now a strategic advantage. Early adopters gain efficiencies, reduce costs, and meet rising customer demand for low-carbon products 40% of firms cite this as a driver. On-site renewables and supply chain decarbonisation offer both savings and brand value. ESG-focused investors increasingly reward climate leadership. UK firms are well-positioned to lead in global markets for clean tech from offshore wind to hydrogen and EVs.
Policy driven growth
The UK government sees net zero as “the industrial opportunity of the 21st century.” Investment is flowing into EVs, battery gigafactories, clean aviation fuel, and more. Entities like Great British Energy and the National Wealth Fund are co-investing in green infrastructure to secure domestic capabilities and export potential. By embedding net zero into its growth strategy, the UK aims to build the industries that will define future success.
Opportunities for individual businesses
For businesses of all sizes, there are tangible opportunities in this transition period:
Cost savings and efficiency
- Many sustainability measures lead to long-term savings. Organisations investing in energy efficiency (better HVAC systems, insulation, optimised machinery) often see immediate reductions in overhead costs and improved margins. Even small changes, like optimising logistics to cut fuel use, directly benefit the bottom line.
Access to finance and incentives
- Green financing is increasingly available – banks and funds offering favourable terms for sustainability projects. Additionally, numerous grants and government incentives exist (for example, grants for electric vans or innovation competitions for clean tech). Proactive businesses can tap into these funding sources, essentially leveraging public money to modernise their operations. This reduces the risk and cost of trying new technologies.
Market demand and new products
- The net zero push is driving demand for new products and services from energy software to eco-friendly materials. Firms offering low-carbon solutions, like retrofits or clean tech, are entering fast-growing markets. UK startups are already scaling in areas like electric heating, carbon accounting, and sustainable food, showing the momentum behind this shift.
Resilience and future-proofing
- Early sustainability investments help future-proof businesses against stricter regulations and climate risks. Proactive firms avoid costly compliance and reduce disruption through measures like flood defences or energy diversification. Net zero efforts drive resilience and adaptability key advantages in a rapidly changing world.
Balancing the transition: Risks and the way forward
While the opportunities of the net zero transition are clear, it must be carefully managed to address legitimate concerns. Key risks include short-term impacts on industry competitiveness, disproportionate burdens on SMEs compared to larger firms, and potential investment shortfalls if policy support falters. To navigate these challenges, a collaborative and strategic approach is needed:
Policy certainty and fairness
- Government policy needs to provide a stable, long-term framework that businesses can plan around. Frequent changes or ambiguity (for example, around carbon pricing or subsidy schemes) can deter investment. The recent improvement in policy clarity has been welcomed uncertainty among businesses about the government’s direction on clean energy dropped in the past year but consistency is key. Policies should also aim for fairness: measures like the UK’s energy price cap and targeted rebates for vulnerable sectors can ensure that smaller businesses and low-income groups aren’t disproportionately hit by transition costs. Conversely, large emitters may face stricter requirements, but also often have more resources to adapt. Maintaining public and political support for net zero will hinge on showing that the transition is “just” and inclusive, with retraining programs in regions that rely on high-carbon industries and support for SMEs to upgrade.
Bridging the investment gap
- The UK needs over £50 billion annually in public and private funding through 2030 to meet net zero goals. Yet a PwC analysis highlights a £130 billion yearly investment gap compared to peer nations a shortfall that must be addressed to enable green industrial transformation. Innovative financing will be key. Expanding green bonds, creating net zero focused public-private funds, and tapping pension or sovereign wealth can unlock capital. The City of London’s financial strength should be directed toward domestic net zero projects, not just global ones. Funding demand-side measures will also boost business confidence by ensuring support for greener operations and customer uptake.
Technology and efficiency to reduce costs
- Innovation is key to cutting the cost of net zero. As technologies like battery storage, hydrogen electrolysers, and carbon capture scale up, their costs are expected to fall just as solar and wind did over the past decade. Targeted R&D investment from government and business should focus on these areas, as each gain in cost-effectiveness eases the financial burden of the transition. Initiatives like the Oxford-Cambridge innovation arc aim to accelerate breakthroughs. Meanwhile, sharing best practices such as AI-driven energy management or fuel-saving logistics can help scale low-cost emission cuts across industry, reducing investment needs and limiting productivity impacts.
Collaboration and support
- No single entity can shoulder the net zero journey alone, collaboration is essential. Organisations, especially smaller ones, benefit from shared resources and knowledge such as industry coalitions that bulk-buy clean energy or create standard green product frameworks. The 2025 BSI Net Zero Barometer found over 80% of businesses want practical support like guides and case studies. Clear standards and certifications can reduce confusion and build trust. Government and regulators must keep working with industry groups to shape effective policies. Encouragingly, climate action is aligning diverse interests, giving all parties a strong incentive to collaborate.
Monitoring and adjusting course
- Finally, as these initiatives roll out, ongoing measurement is essential to ensure the net zero transition stays on track. Keeping an eye on metrics like energy prices, investment levels, and emission reductions helps identify pressure points and guide policy adjustments. If costs spike or funding programs are underused, responses like relief measures or simplified access may be needed. Flexibility will be key in a dynamic transition.
Building a sustainable and prosperous future
The journey to net zero is a complex balancing act, and UK industries have valid concerns around funding, cost distribution, and competitiveness. Addressing these through clear policy, smart financing, and collaboration is essential to ensure a fair transition.
Yet the evidence shows net zero is more than a cost it’s a strategic investment. With the right approach, it can lower long-term energy bills, drive innovation, and create jobs across the UK. One analysis suggests the transition could be achieved at minimal cost just a few pounds per person per week while delivering cleaner air, better homes, and economic renewal. The cost of inaction, by contrast, would be far greater.
Achieving net zero is not just an environmental necessity, it’s an opportunity to secure our economic future. If we invest wisely and collaboratively today, we’ll reap the benefits of a cleaner, stronger economy tomorrow. This sentiment echoes the renewed momentum following NESO’s Whole Energy Market Strategy, which focuses on making the transition affordable, secure, and inclusive.
By unlocking finance, scaling technology, and strengthening public-private partnerships, the UK can turn net zero into a win-win: meeting climate goals while boosting economic growth. Challenges lie ahead, but so do transformative opportunities. Businesses that act early by improving efficiency, entering green markets, and engaging with policymakers will be best placed to lead. As TEAM Energy’s experience shows, supporting organisations through this shift not only advances sustainability, but often delivers real operational and financial gains.
