Budget 2026 commits the government to approving only new electricity generation projects that demonstrably reduce consumer bills, signalling a tilt towards low‑marginal‑cost technologies such as offshore wind, solar PV and nuclear with Contracts for Difference–style revenue models. Ministers also pledged to accelerate grid reforms, likely prioritising transmission reinforcements, new 400kV corridors and faster connection processes to clear the current multi‑year queue. For civil and geotechnical contractors, the shift points to more balance‑of‑plant, substation and cable‑route work, but tougher value‑for‑money scrutiny on capex and programme risk.

Financing for the 3.2GW Sizewell C nuclear plant on the Suffolk coast has been condemned as “a terrible deal for the UK taxpayer” by the House of Commons Public Accounts Committee, which scrutinises value for money in major public projects. MPs are challenging the current funding model, which relies heavily on long-term consumer and taxpayer commitments to underwrite construction and financing risk. The criticism raises fresh uncertainty for large, capital-intensive low‑carbon infrastructure schemes that depend on complex, multi-decade funding structures.

Government payouts under the Renewables Obligation to Exchequer Scheme have exceeded £1bn in six months since its launch in April, subsidising household-scale renewable electricity generation across the UK. The scheme redirects Renewables Obligation buy-out and late payment receipts from suppliers into direct bill support, effectively lowering unit costs for homes using technologies such as rooftop solar PV and small wind. For infrastructure planners and grid engineers, this signals continued policy backing for distributed generation, with implications for low-voltage network capacity, export constraints and smart metering roll-out.
