# MPs Criticize Sizewell C Nuclear Project as Costly Taxpayer Burden Public accounts committee warns of extraordinary financial risks and potential billpayer impacts for nuclear plant. - **Source:** [Business | The Guardian](https://www.theguardian.com/uk/business) - **Published:** 2026-10-28 - **Topic:** [Business](https://brifing.si/c/business) - **Original article:** - **On Brifing:** https://brifing.si/s/76058099-70f1-48b0-86b4-fe0cd304a9ec ## Extraordinary Financial Risk Exposure The Public Accounts Committee has labeled the Sizewell C funding model a terrible deal for taxpayers. Estimates suggest total costs could reach £47.7bn by 2043. Billpayers face significant exposure, potentially covering £9.8bn for construction and an additional £12bn over the plant's 60-year operational lifespan, creating long-term financial pressure on households. ## Government Stake and Ownership The UK government currently holds a 44.9% stake in the project, a position solidified after buying out China's CGN due to national security concerns. French developer EDF retains 12.5%, while private investors like Centrica and La Caisse hold 15% and 20% respectively. This structure forces the state to absorb major cost overruns. ## Private Investor Return Disparity Critics highlight a stark imbalance in risk distribution between public and private entities. While taxpayers are liable for multibillion-pound overruns, private investors are only required to contribute an additional £30m if costs escalate. Sir Geoffrey Clifton-Brown noted that private investors stand to gain significant returns while consumers face higher energy bills. ## Government Defense of Strategy Government spokespeople argue the committee ignores incentives designed to ensure efficient construction. They claim the project will eventually save £2bn annually across the energy system. Currently, over 2,000 workers are active on the site, and officials maintain that the plant is essential for long-term national energy security and cost reduction. ## Grid Balancing and Reliability The Nuclear Industry Association argues that Sizewell C provides reliable, clean power that offsets grid management costs. Tom Greatrex noted that consumers already paid £2.8bn this year to manage grid dysfunction, including payments to stop wind generation and procure gas backup. Nuclear power is presented as a solution to these systemic costs. ## Calls for Financial Transparency The committee has formally requested that the government provide the specific scenario analysis used to underpin its cost estimates within three months. Furthermore, ministers are now required to submit progress updates every six months. This oversight aims to monitor the project's development and ensure greater accountability regarding the use of public funds. ## Alternative Perspectives on Abandonment Critics, including academics and campaign groups, suggest that abandoning the project now would be cheaper than the long-term financial burden on households. They argue that the current funding model offers a free ride for investors at the expense of taxpayers. They have urged the government to abandon this specific financing structure for future projects. ## Future Policy Implications The controversy surrounding Sizewell C highlights the tension between infrastructure investment and consumer protection. The committee's report serves as a warning for future nuclear developments, demanding a shift in how risks are shared. The government must now balance the need for energy transition with the political necessity of protecting taxpayers from spiraling costs. ## Sources covering this story - https://www.theguardian.com/business/2026/oct/28/plan-for-multibillion-pound-sizewell-nuclear-plant-a-terrible-deal-for-uk-taxpayers-mps-say — --- _Summary written by Brifing from the original reporting.
