The UK’s Net Zero 2050 target is reshaping sectors, reframing the labour market, and driving demand for new skills. Decarbonising homes, businesses, and transport demands a workforce capable of delivering large-scale retrofit projects, installing renewable technologies, and overseeing sustainable construction programs.
According to the Climate Change Committee (CCC), between 135,000 and 725,000 net new jobs could be created by 2030 in low-carbon sectors, such as retrofitting, renewable energy generation, manufacturing of electric vehicles and environmental performance analytics.One urgent example is the UK Government’s target to install 600,000 heat pumps annually by 2028, requiring thousands of new installers and maintenance professionals. However, employers are already reporting significant recruitment challenges.
The UK’s green jobs landscape
Green skills refer to knowledge and practices that reduce environmental impact, support sustainability, and advance the low-carbon transition. In construction and the built environment, they cover everything from heat pump installation to waste management and energy modelling.
However, the supply of workers with these skills is not matching growing demand, especially in the UK. A 2024 LinkedIn study found that the UK has one of the widest gaps between the demand for green talent and its availability, second only to Portugal. Although the demand for green professionals is increasing, the pace at which the workforce is developing these skills hasn’t kept up.
Which is why, at Quantum Training, we’re working closely with colleges, training providers, government institutions to help bridge this gap. Through our ongoing work with FE colleges, employers, and industry partners, we’ve been able to get insight into how the UK’s green skills landscape is evolving. We’ve observed which green skills are becoming essential, why they matter to employers, and how colleges and training providers can play a role in helping close these gaps.
Top green skills in the built environment
1. Retrofit and energy efficiency
Retrofitting the UK’s ageing housing stock is one of the key priorities of the government, and an essential step towards UK’s Net Zero ambition. With 80% of the homes that will exist in 2050 already built, upgrading them to meet energy efficiency standards is essential, and also a huge challenge.
Retrofit skills include PAS 2035 compliance, insulation techniques, airtightness, ventilation, and moisture management. However, there is a severe shortage of retrofit coordinators and technicians, and employers are struggling to meet project demand.
Government-backed schemes, such as the Local Skills Improvement Plans (LSIP), are helping colleges invest in green skills training, but a lot more needs to be done to retrofit almost 29 million homes by 2050.
2. Low-carbon heating systems
Replacing gas boilers with renewable alternatives is also a key component of the UK’s Net Zero ambition. Skills in installing Air Source Heat Pumps (ASHPs) and Ground Source Heat Pumps (GSHPs) are in particularly high demand, and we see this demand in our work with colleges needing ASHP & GSHP training bays as well.
To meet the government’s 600,000 installations per year target by 2028, thousands of additional workers will be needed across every region. Currently, only 2 in 5 installers in the UK consider themselves skilled in heat pump technology, clearly illustrating the need to upskill the current workforce.
3. Solar PV and renewable energy systems
The UK has plans to triple it’s solar capacity by 2030. This has created a huge demand for workers skilled in solar panel installation, battery storage, and hybrid energy systems, with employers requiring technicians who can design, install, and maintain these integrated systems.
The solar sector could support around 35,000 jobs by 2030, making it one of the fastest-growing areas in the green economy. To meet this demand, colleges and training providers must expand courses that blend technical expertise with practical experience.
Building this talent pipeline will be key to ensuring the UK can deliver on its renewable energy ambitions.
4. Circular economy and sustainable construction
The construction sector generates over 60% of UK waste, making circular economy practices essential if the UK is to achieve it’s Net Zero ambition.
And that requires a workforce which understands sustainable material selection, recycling processes, and waste reduction strategies. Skills in low-carbon materials, such as recycled steel and limecrete, are also becoming key for public and private sector projects.
These practices align with guidance from the UK Green Building Council and are expected to become standard industry requirements over the next decade.
5. Data and environmental performance analytics
As construction becomes more digitised, the ability to monitor and optimise building performance is growing in importance. Skills in tools such as SAP, SBEM, and IES are critical for assessing energy efficiency and carbon emissions.
Employers need workers who can analyse this data to improve building design, support compliance, and identify areas for sustainability improvements.
The role of “Essential (Soft) Skills”
In retrofit and low-carbon work, technical expertise is vital, but equally so are essential (soft) skills. In the UK, the case for essential skills is compelling. About 57% employers say they value essential skills more than technical skills when recruiting, and 98% of teachers in England recognise essential skills as important for learners’ employment opportunities.
Some of these skills include problem-solving, communication, leadership and adaptability, all of these vital for collaborative, multi-disciplinary projects that require cross-sector expertise.
Colleges need to focus on embedding these skills into every project, giving learners the right tools to succeed in their careers and eventually lead to the UK’s transition to a green economy.
How colleges and training providers can help
FE colleges can play an extremely important role in addressing the green skills shortage. They have local roots and access to local businesses, and can provide hands-on, practical training that is tailored to the local need.
However, to succeed, colleges require:
- Modern green skills training facilities including low-carbon training bays for heat pumps, solar PV, and retrofit work.
- Partnerships with awarding bodies for accredited courses aligned with employer demand.
- Government support in terms of access to schemes like LSIP to secure funding for infrastructure and training delivery.
Organisations such as GSAP (Green Skills Apprenticeship Partnership) are also helping significantly in providing support and clear routes into green careers.
Quantum Training, in this context, works between the colleges and the industrial partners in providing the facilities and co-developed courses with the NOCN Group that underpin such a transformation.
“The UK urgently needs more skilled professionals to deliver the technologies that will power a low-carbon future, and practical, hands-on training is the only way to build that capability at scale,” said Maria Gonella, Managing Partner at Quantum Training, while speaking at a launch ceremony of the training facilities installed by Quantum Training at London South Bank Technical College. “By combining industry expertise with education, we’re helping to close the green skills gap and ensure the workforce is ready to meet the demand for renewable heating and energy solutions,” she further added.
Conclusion
The UK’s Net Zero journey will depend on a workforce ready to deliver retrofit, renewable energy, and sustainable construction at scale. Employers are already facing shortages in these core skill areas, with recruitment challenges growing year on year.
By investing in facilities, courses, and partnerships, FE colleges and training providers can help close this gap and prepare learners for the jobs of tomorrow. With the right collaboration between government, employers, and education, the UK can build a workforce ready to power its green future.
