Study Reveals Staggering £615 Billion Green Infrastructure Investment Gap Confronting the UK





In a recent in-depth analysis, the Association of British Insurers has unveiled a colossal £615 billion chasm in the UK's green infrastructure investment requirements. This monumental funding challenge looms over the nation as it strives to fulfil its commitments for energy, transportation, and housing infrastructure until 2030. The UK, in its pursuit of onshore and offshore wind projects, carbon capture and storage initiatives, electric vehicle charging networks, rail electrification, new housing developments, and insulation upgrades, finds itself in a pressing situation.


The findings of a study commissioned for the Investment Delivery Forum, established by the Association of British Insurers (ABI), underscore a stark reality: the UK has secured just over half of the £1.3 trillion needed to meet its infrastructure demands for this decade, leaving a staggering investment deficit of approximately £615 billion. Notably, the private sector is anticipated to play a pivotal role in bridging the lion's share of this shortfall, amounting to around £350 billion.


The green infrastructure investment gap translates to an annual shortfall of £75 billion until 2030, with private funding facing an annualized gap exceeding £40 billion. Even more concerning is the projection that, at the current investment rate, this gap is poised to swell from £615 billion in 2030 to a staggering £1.5 trillion by 2050.

Clare Bousfield, sub-chair of the Investment Delivery Forum and deputy president of the Association of British Insurers, said the UK was facing a "mammoth infrastructure investment challenge" as she urged the government to push through reforms that would allow the insurance industry to boost investment in low carbon infrastructure.


"The ongoing Solvency UK reforms are crucial in helping us to channel around £100bn into green and good infrastructure and narrow this investment gap," she said. "We have established the Investment Delivery Forum to ensure that once unlocked, these funds can be deployed swiftly.

"We are working hard to lay this groundwork, but we want to hear from project owners as part of this process, as well as telling the infrastructure community what makes projects investable for the insurance and long-term savings industry."


These reforms encompass streamlining reporting requirements to reduce administrative burdens on insurers, adopting a more "principles-based approach" to assessing firms' internal models and introducing a "mobilization" regime that grants newly authorized insurers greater flexibility in their investment choices.

Notably, insurers such as Just Group and Aviva have already taken significant steps as critical investors in the UK's green infrastructure sector. Just Group, for instance, has invested £42.5 million in refinancing Vantage Solar UK, the owner of 24 projects generating 365MW of power across the UK. Aviva, on the other hand, has directed £3.2 billion toward various transport projects, including a substantial contribution of £110 million to Connected Kerb, aiming to deploy 190,000 on-street EV chargers by 2030.


Earlier this year, the ABI established the Investment Delivery Forum, a collaborative platform involving leading insurers, industry experts, and partners, to accelerate efforts in closing the green investment gap. This revelation of the UK's infrastructure funding challenge aligns with the National Infrastructure Commission's assertion that substantial private sector investments, ranging from £20 billion to £35 billion annually between 2025 and 2050, are imperative to facilitate the transition to increased renewable electricity capacity, enhanced grid flexibility, and the development of hydrogen and carbon capture and storage facilities. The report emphasizes that achieving economic growth and climate targets is attainable, provided the government takes the necessary policy measures to unlock tens of billions of pounds in additional investment to modernize the UK's ageing infrastructure.
