The UK Budget conditions government purchases and construction of new clean-power projects on lower bills and grid access, while also requiring system benefits, as transmission constraints continue to cost consumers billions.
In his Oct. 28 Budget speech, Chancellor John Healey said: “This government will only buy and build new projects when they lower bills and when they can connect to the grid.” The Budget document also says new generation should benefit the energy system. The speech applies its two conditions to clean-power projects generally and does not identify offshore wind separately.
The National Audit Office (NAO) put electricity grid-constraint costs at £1.9 billion in 2025-26 and said they could reach £7.8 billion by 2030 without concerted action. Consumers ultimately bear the charges. When network limits prevent electricity from reaching areas of demand, the system operator has paid wind farms to curb output and gas plants to produce more. The NAO links the cost outlook to delays in necessary grid upgrades. NAO head Gareth Davies said: “Failure to implement these necessary grid upgrades will hamper economic growth as well as increase consumer bills.”
The Guardian reported that Healey would veto new offshore wind projects if they would not lower bills. That framing does not appear in the published Budget speech, which names no offshore wind proposal to be rejected. The government’s Clean Energy Industries Sector Plan sets a separate target of 43 to 50 gigawatts of offshore wind capacity by 2030.
The Budget schedules a comprehensive Cost Control Framework for the 2027 spending review and includes a consultation on wholesale Contracts for Difference, which set prices paid to some renewable projects. The government says the changes are intended to reduce exposure to volatile international gas prices. It also says Allocation Round 8 will lower bills and benefit energy security and climate goals, with further reforms planned before Allocation Round 9.
