The United Kingdom stands at a pivotal juncture in its quest to decarbonise its building stock, a critical element of its broader ambition to transition to a net-zero economy. As energy costs escalate and environmental imperatives intensify, enhancing the energy efficiency of the UK’s buildings has become paramount. However, a significant skills gap within the workforce threatens to undermine these efforts, posing a substantial risk to the nation’s climate objectives. Recent research by Business in the Community (BITC) reveals a concerning disconnect: only one in four UK workers anticipates needing new skills due to climate change. This mismatch underscores a critical bottleneck in the UK’s decarbonisation pathway, particularly in the construction and building sectors, which account for a considerable portion of the country’s greenhouse gas emissions.

The urgency of addressing this skills gap is further highlighted by a LinkedIn report projecting that by 2050, the demand for green skills will outstrip supply, with twice as many jobs requiring such skills as there will be qualified professionals to fill them. The BITC’s Green Skills Lab Blueprint provides a framework for tackling this issue, advocating for the development of workforce action plans to cultivate the requisite green skills. Despite these efforts, the research indicates a lack of proactive measures among UK business leaders, with six in ten yet to assess the operational risks and opportunities posed by climate change. Notably, only a third of SME leaders have begun to address this challenge.
To bridge this gap, businesses must anticipate how future roles will evolve and identify those most likely to be affected. It is essential to support employees through these transitions and engage stakeholders to shape policies that facilitate large-scale business action. Gudrun Cartwright, Climate Action Director at BITC, emphasises the necessity of ingraining green skills within organisational culture and strategy. Leading companies such as WJ Group, British Land, and the Construction Industry Training Board (CITB) exemplify this approach. WJ Group, committed to achieving net-zero emissions by 2040, has developed a suite of green competencies to meet this goal. Similarly, British Land is leveraging social mobility and educational partnerships to open up green job opportunities for communities.
The CITB has been proactive in equipping its workforce with the necessary skills to support environmental objectives, implementing a Green Workforce Plan that categorises skills into basic, essential, and technical levels. This stratified approach enables targeted upskilling initiatives. Simultaneously, companies like SUEZ are transforming their business models to focus on energy and materials recovery, necessitating a renewed skill set and mindset among their workforce. Comprehensive skills assessments and agile internal systems are part of SUEZ’s strategy to meet the evolving demands of a green economy.
The challenge of green skills is not solely a business concern but a national issue requiring decisive government action. The UK government must champion training programmes and formulate a robust low-carbon skills strategy to avoid jeopardising its net-zero aspirations and ensure workforce employability in a rapidly evolving job market. Addressing this skills gap calls for a concerted effort from businesses, government bodies, and educational institutions. By prioritising workforce development and fostering a culture of continuous learning, the UK can navigate the transition to a net-zero economy while safeguarding a sustainable future for its workforce.
In parallel, policy support is integral to the decarbonisation of the UK’s building stock. Current reliance on gas for domestic heating, coupled with inadequate insulation, has left many households vulnerable to energy poverty. The existing policy framework is deemed insufficient, with initiatives often criticised for being underdeveloped and lacking adequate financial backing. Dr. Salvador Acha from Imperial College London advocates for policies that comprehensively address efficiency standards, heat decarbonisation, energy renovations, and skills training. Successful international policies, such as Germany’s KfW Efficiency House standard, offer valuable insights. This programme, which provides grants and loans for property upgrades, has achieved significant CO2 emissions reductions and could serve as a model for the UK.
The UK’s Energy Performance Certificate (EPC) scheme requires enhancement, with a more holistic standard needed to drive progress. Collaboration with organisations like CIBSE and academia could lead to the development of bespoke EPC standards suited to diverse property types. Retrofit policies, crucial for improving building stock, have suffered from reduced government incentives over the past decade. Italy’s Superbonus scheme, offering tax credits for energy renovations, stands as an exemplary model. The recent introduction of the £1 billion ECO+ scheme marks positive progress but falls short of meeting the demands of a nationwide retrofit endeavour.
A comprehensive national retrofit strategy, underpinned by substantial investment, could stimulate growth in the construction sector, enhance property value, and reduce energy costs. Prioritising insulation would decrease energy demand and bolster energy security. Simultaneously, heat decarbonisation through technologies like heat pumps and district heating networks must be pursued. The Bristol City Leap project, involving Vattenfall Heat UK, exemplifies how cities can adopt integrated approaches to decarbonisation by expanding heat networks and enhancing energy efficiency. The forthcoming Energy Bill is anticipated to further empower local authorities to designate areas for heat networks, thereby streamlining decarbonisation efforts.
The UK’s decarbonisation ambitions remain within reach, provided there is a strategic blend of policy support, investment, and skills development. By learning from successful international precedents and fostering cross-sector collaboration, the UK can overcome existing challenges and chart a sustainable, energy-efficient future for its buildings and communities.
