Britain's Nuclear Renaissance Faces Mounting Cost Pressures
Authored by Felicity Bradstock via OilPrice.com,
Sizewell C and Hinkley Point C are expected to play a major role in expanding Britain’s nuclear generation capacity and reducing dependence on fossil fuels.
Both projects have faced concerns over delays and rising costs, with Hinkley Point C’s estimated price nearly doubling from its original forecast.
The U.K. aims to increase nuclear capacity to 24 GW by 2050, supported by large-scale reactors and emerging small modular reactor technologies.
The United Kingdom is focused on diversifying its energy mix away from fossil fuels to boost energy security and support decarbonisation aims.
This includes expanding its nuclear power capacity with the development of two large-scale nuclear plants - Sizewell C and Hinkley Point C, as well as developing small modular reactors (SMR).
However, its nuclear ambitions have not quite gone to plan, following years of delays and rising construction costs.
Sizewell C in Suffolk, eastern England, received its planning approval in 2022, was greenlit in 2025, and is expected to be operational by around the late 2030s. Investment for the development comes from the government, EDF Energy, Centrica, La Caisse, and Amber Infrastructure Limited. The project is expected to create 17,000 jobs during peak construction, including 7,900 in Suffolk. Once operational, the nuclear plant will produce up to 3.2 GW of clean electricity to power up to 6 million homes.
The government expects the plant to cost around £38 billion to develop and says it could provide around £2 billion a year in savings from the electricity system, compared to using other low-carbon technologies. However, Sir Geoffrey Clifton-Brown, the chair of the public accounts committee, which oversees the work of the National Audit Office (NAO), warned that “Sizewell C is a project of exceptional scale, complexity and significance for taxpayers… Experience from comparable nuclear projects in the UK and overseas highlights their vulnerability to delays and cost overruns.”
To date, the French nuclear firm EDF has invested £1.1 billion for a 12.5 percent stake in the project, while the U.K. government has invested £14.2 billion as the majority stakeholder. The NAO fears that if not properly managed, construction could run significantly over budget, as seen with other nuclear developments in recent years. This would make the break-even time much longer for consumers footing the construction costs through their taxes.
The NAO has, therefore, urged the government to mitigate the risk by using “close monitoring, greater transparency to parliament, and by securing value for money from the significant public and private investment”.
Lessons for building Sizewell C come from the construction of EDF’s Hinkley Point C plant, the first nuclear plant to be developed in the U.K. in over a decade. Hinkley Point C was approved by the U.K. government in 2013 and was greenlit in 2016. It is expected to begin operations in 2030, a year later than originally planned.
The project has faced several delays and price increases, the most recent of which was announced by EDF in February, adding a projected £2.16 billion. The plant is now expected to cost around £35 billion in total, almost double the original £18 billion 2016 estimate. EDF’s CEO, Bernard Fontana, said the new forecasts were “more realistic” and said that the 2030 launch of operations was “within a range that has not changed” since 2024, when it said operations would start between 2029 and 2031.
Once operational, Hinkley Point C is expected to provide around 7 percent of Britain’s electricity demand. While EDF’s two U.K. nuclear projects could help diversify the country’s energy mix and reduce reliance on fossil fuels, critics worry that the development of the two plants will face further delays and come in significantly over budget. EDF’s only other nuclear project using the same reactor type, at Flamanville in France, became fully operational in December after a delay of over 12 years; meanwhile, costs soared from an initial estimate of £2.85 billion to over £11.4 billion.
In 2025, the U.K. was deemed the “most expensive place in the world” to build nuclear power plants in a government review.
This was largely owing to “overly complex” bureaucracy around the sector. Nuclear Regulatory Taskforce said that “radical reset” of the rules around nuclear power could save Britain “tens of billions” in costs and reverse the industry’s “decline” in recent years. This suggests that the government must work to streamline bureaucratic processes without compromising safety and consider other cost-cutting options to avoid cost increases in nuclear development.
At the time, the Taskforce chair, John Fingleton, stated, “Our solutions are radical, but necessary. By simplifying regulation, we can maintain or enhance safety standards while finally delivering nuclear capacity safely, quickly, and affordably.”
In 2024, the U.K. government announced a target to increase the country’s nuclear power capacity fourfold, to 24 GW by 2050.
This will be achieved through the development of Sizewell C and Hinkley Point C, as well as through the deployment of innovative small-scale nuclear technologies.
This is an ambitious target, but through the development of a wide range of nuclear technologies, it could be achievable.

Four leading AI models discuss this article
"Regulatory reform could flip Sizewell C from a cost-overrun disaster into a manageable infrastructure play, but only if the government actually executes—and the article provides zero evidence it will."
The article frames this as a cautionary tale, but the real story is regulatory capture masquerading as reform. Yes, Hinkley Point C doubled from £18B to £35B—catastrophic. But the 2025 'most expensive place to world' finding triggered a Nuclear Regulatory Taskforce calling for 'radical reset' of rules. If that actually happens, Sizewell C's £38B estimate becomes a ceiling, not a floor. The Flamanville comparison is misleading: French bureaucracy ≠ British. What's missing: zero discussion of whether the 24 GW target is even economically necessary versus alternatives (renewables + storage), or whether private capital will actually materialize beyond EDF's token £1.1B stake.
The 'radical reset' is political theater—regulators rarely simplify without creating new complexity, and safety compromises in nuclear invite public backlash that delays projects further. Sizewell C won't break even until 2050s at best, making it a fiscal millstone, not a win.
"Bureaucracy cuts could still deliver net savings on the 24 GW target even after documented overruns if implemented before Sizewell C peaks construction."
The article underscores persistent overruns at Hinkley Point C (now £35B vs original £18B) and Sizewell C (£38B target) plus the 12-year Flamanville delay, yet it underplays the 2025 Nuclear Regulatory Taskforce finding that UK nuclear construction is the world's costliest due to bureaucracy. A 'radical reset' could cut tens of billions while preserving safety, directly supporting the 24 GW by 2050 goal via SMRs and large reactors. Centrica's (C) stake in Sizewell C and EDF's exposure make both sensitive to whether reforms accelerate or stall before late-2030s commissioning.
Historical evidence from Flamanville and Hinkley shows regulatory inertia and supply-chain issues often defeat streamlining promises, leaving taxpayers and investors with multi-year delays regardless of taskforce recommendations.
"The UK's nuclear ambition is currently failing a cost-benefit analysis due to systemic bureaucratic inertia that renders long-term budget forecasts essentially meaningless."
The UK's nuclear strategy is currently a fiscal sinkhole masquerading as energy policy. With Hinkley Point C costs doubling to £35 billion and the Flamanville project in France serving as a cautionary tale of 12-year delays, the 'nuclear renaissance' is structurally compromised by institutional inefficiency. The government's £14.2 billion commitment to Sizewell C risks a 'sunk cost fallacy' trap, where capital is diverted from more agile, modular renewables or battery storage. Unless the 'radical reset' of regulatory bureaucracy mentioned by the Taskforce actually materializes—which is historically unlikely in the UK—these projects will likely face further inflationary pressure, eroding any long-term ROI for taxpayers and institutional investors alike.
If the UK successfully standardizes the EPR reactor design and slashes regulatory lead times, the long-term levelized cost of energy (LCOE) could drop significantly, turning these plants into high-margin, base-load assets that hedge against volatile gas prices.
"Near-term cost overruns and schedule slippage threaten the viability of the 24 GW 2050 target unless financing, regulatory reform, and delivery risk are credibly de-risked."
Britain’s nuclear push hinges on Sizewell C and Hinkley Point C, but the cost math is painful: Hinkley’s total now around £35B (up from £18B) and Sizewell C pegged near £38B. The NAO warns of overruns and the project’s scale creates tax- and bill-related risk. Regulatory bottlenecks and high sovereign risk for private lenders raise the cost of capital, making a 24 GW target by 2050 look ambitious unless there’s credible, long-term capacity payments and risk-sharing. The article omits potential offsets: SMR economics, international partnerships, and the possibility that reforms could eventually curb costs. Near term: execution risk dominates; long term: outcome uncertain but not zero.
But if the government provides strong guarantees and a clear, long-term price path, capital could still flow despite costs; and SMRs, if proven at scale, could materially compress costs and change the math.
"The 'radical reset' can't solve the fundamental problem: nuclear's LCOE is structurally uncompetitive without hidden subsidies, and CfD transparency makes those subsidies politically untenable."
ChatGPT flags capacity payments as a potential fix, but nobody's named the real mechanism: Contracts for Difference (CfD). UK already uses these for renewables. Nuclear's problem isn't theoretical—it's that CfD strike prices for nuclear dwarf wind/solar by 3-4x, making them politically toxic. That's the hidden veto. Reforms don't fix economics; they just shuffle who bears the cost. SMRs are a distraction until one actually reaches grid parity.
"RAB model exposes consumers to overruns more directly than CfD, inviting backlash that Taskforce changes won't neutralize."
Claude flags CfD strike prices as the hidden veto on nuclear, but the deeper flaw is that RAB financing for Sizewell C already transfers overrun risk directly to consumer bills. This creates a political tripwire the article and prior comments ignore: any further delay pushes household costs higher just as renewables subsidies fall, guaranteeing a backlash that could kill the 24 GW target regardless of Taskforce reforms.
"The political risk of grid instability from relying solely on renewables outweighs the political risk of high consumer bills from nuclear cost overruns."
Grok, you're right about the RAB model being a political tripwire, but you've missed the institutional reality: the UK government is desperate for baseload to replace retiring gas plants. The 'backlash' is irrelevant because the alternative—intermittent renewables without massive, unproven long-duration storage—risks grid instability that would be even more politically explosive. The real risk isn't consumer bills; it's the sovereign credit rating impact if these projects continue to hemorrhage capital without delivering reliable MWh.
"The real risk to 24 GW by 2050 is execution speed, not the nominal CfD strike price or a regulatory reset."
Claude’s emphasis on CfD as the hidden veto misses the bigger lever: RAB financing, consumer bill exposure, and timing risk. Even with a 'radical reset,' the cost of capital remains hostage to political risk, procurement delays, and supply-chain fragility. Short-duration reforms that don’t fix project governance likely just shift who bears the pain, not avoid overruns. The real risk to 24 GW by 2050 is execution speed, not strike-price parity alone.
The panel consensus is that the UK's nuclear strategy is fiscally unsustainable due to persistent cost overruns, regulatory inefficiencies, and political risks. The 24 GW target by 2050 is at risk unless significant reforms are implemented and executed swiftly.
The single biggest opportunity flagged is the potential for 'radical reset' of regulatory bureaucracy to cut costs while preserving safety, supporting the 24 GW target via SMRs and large reactors.
