If the spring had been about prices, June was about investment. The Spending Review set out the government's medium-term priorities, with energy security and the clean power transition featuring prominently. Central to the picture was Great British Energy, the publicly owned company established to invest in clean generation — a structural development whose effects would unfold over years rather than months.
Great British Energy Takes Shape
Headquartered in Aberdeen, Great British Energy was created to invest in and accelerate clean energy projects, from established renewables to emerging technologies. Its establishment marked a notable shift in the state's role in the energy system — from regulator and bill-payer of last resort towards active investor and project developer. For the market, it signalled long-term political commitment to the clean power build-out.
A long-term signal
Public investment vehicles work on a horizon of years. Their immediate effect on bills is limited, but they shape the pipeline of generation and the confidence of private investors — and therefore the shape of the market advisors will operate in over the coming decade.
What It Meant for the Supply Chain
For brokers, agents and consultants, the direct impact of the Spending Review was modest in the short term. Its significance lay in direction. A market underpinned by sustained public and private investment in clean generation is one in which flexibility, data and new tariff structures grow steadily more central — reinforcing the case for advisors to broaden their capabilities beyond straightforward procurement.
Reading the Direction of Travel
June's announcements were a reminder that the most important developments in energy are not always the ones that move bills this quarter. The investment decisions taken in 2025 will shape the generation mix, the grid and the products available to customers for years. Advisors who track this direction — and align their offering with where the market is heading — build businesses with staying power.
