The options: what else the money could have done

Paid for by the public: as electricity billpayers, and as taxpayers standing behind the loans.

This page sets out alternative paths at their documented costs, results and risks, from official figures, next to what was actually spent (the real cost). It does not recommend one.

Labels used: official = a government, regulator, court or audit-body document; filed = a company's own filed accounts; press = a company release or trade press; intergovernmental = an international agency; academic = a university explainer or paper; estimate = this site's arithmetic or an assumption, shown. Where a source says "not published", this page says so. Each figure keeps its own price year; none has been forced equal.

1. Norway: the same size at its peak, a different policy

The UK and Norway offshore areas peaked at almost the same size: the UK at 4.49 million barrels of oil equivalent a day in 1999, Norway at 4.54 in 2004. Since then the two have moved apart. The tables below set out output, tax rates, the state's stake and state revenue, then what the regulators say about geology and policy.

Geology and policy

No regulator quantifies how much of the output gap is due to geology and how much to policy. The sources hold no counterfactual, such as UK output under the Norwegian system. The regulators and governments describe maturity in their own words.

What it would cost
Not published. No source holds a costing of the UK adopting Norway's tax or state-stake model.
What it would deliver
Norway's 2025 output is 4.122 million barrels of oil equivalent a day against the UK's 1.094, and it has risen 5.0% since 2015 while the UK has fallen 28.9%. No source measures how much of that is due to policy.
Documented risks
Norway's state net cash flow ranged from £10.8bn (2020) to £114.4bn (2022) in constant 2026 prices. Its official projection for 2030 is 3.497 million barrels of oil equivalent a day, below 2025. The regulator says its longer-term level is uncertain. The UK has no state upstream stake to compare.

What it would cost
Rosebank capital cost: not published. Jackdaw: over £1bn spent to date by the developer. Public revenue at stake: the Energy Profits Levy raised £2,632m, £3,587m and £2,857m in 2022-23 to 2024-25, and the OBR forecasts £2.5bn in 2025-26 falling to nil from 2028-29. The cost of any change to the levy: not published. A UK gas reservation: not published.
What it would deliver
West of Shetland: mean 4.7 billion barrels of oil equivalent of play-level prospective resource outside mapped leads and prospects (no cut-offs), and separately 0.7 in mapped leads and prospects that pass NSTA's cut-offs. Rockall Trough: mean 2.5. NSTA projects UK output of 0.162 million barrels a day of oil and 0.325 billion cubic feet a day of gas in 2040 on current plans. Domestic gas carries about one-third of the emissions intensity of imported LNG (28 against 85 kgCO2e per barrel of oil equivalent, 2024, combustion excluded). Rosebank: 70,000 barrels a day capacity. Jackdaw: about 6.5% of UK Continental Shelf gas production at peak.
Documented risks
Lifetime emissions, developers' high cases: Rosebank 254 MtCO2e (P10; the developer's most likely case about 30% lower), Jackdaw 35.8 MtCO2e (highest-production case, scope 3). Legal: consents reduced in January 2025 and the new decision still open. Prospective volumes are not reserves. Capital spending fell from £5,703m (2024) to £4,972m (2025), and NSTA projects £1.68bn by 2031.

3. Gas with carbon capture

This option pairs gas generation with capture and storage of the carbon dioxide. The government has committed £21.7bn over 25 years to the first two clusters. The generation cost sits close to offshore wind in the government's own table, and the National Audit Office has set out the delivery risks.

Documented risks
NAO: 2030 ambitions will be a struggle; funding unlikely to be enough; no credible alternative to carbon capture in the government's pathway; technology nascent; value-for-money test not complete; £8 billion to £10 billion of private finance needed in one year.

What it would cost
Not published. No official capital or production cost for UK shale was found. BEIS's 2022 line is that lifting the pause "will enable drilling to gather this further data".
What it would deliver
Gas in place, Bowland-Hodder: 822 to 2,281 tcf, central 1,329 tcf (BGS/DECC, 2013). Recoverable: BGS/DECC said it cannot be estimated. The official yield figures are 2.1 to 4.7 tcf (about 59 to 133 bcm) for the Upper Bowland, on analogies with two US shales (2010), about 2 to 4 years of 2025 UK gas production (estimate). BGS in 2019 and 2022 says the true figure may be much lower.
Documented risks
The OGA found in 2019 that induced earthquakes could not be accurately predicted; BGS in 2022 said forecasting large earthquakes, induced ones included, "remains a scientific challenge". A magnitude 2.9 event occurred at Preston New Road on 26 August 2019. Knowledge gaps in other basins. Policy changed three times: moratorium in November 2019, lifted in September 2022, re-imposed in October 2022 (the last on trade-press evidence).

5. Nuclear in series

This option builds the same reactor design repeatedly. Project costs for Hinkley Point C and Sizewell C are on the nuclear page. This section covers only the evidence on whether repeat building lowers cost. The evidence points both ways.

The NEA table lists the Korean figures next to Vogtle 3 and 4 at US$4,300 to 8,600 and Flamanville 3 at US$1,886 to 8,620, so Korean costs were lower than Western ones even though they rose against budget. The French reading: costs fell between paired units on one site and for follow-on units, and rose across the national series as safety rules tightened.

What the UK government says. DESNZThe UK government department responsible for energy policy, including subsidy auctions and community fund guidance. more › states the benefit as reduced risk of time and cost overruns, not as a quantified fall. A UK percentage cost fall from a fleet of identical reactors is not published. The Nuclear Regulatory Review summary (24 November 2025) says the UK "has become the most expensive place in the world to build nuclear projects". official

What it would cost
Hinkley Point C: £35bn to £36bn in 2015 prices (EDF's latest scenarios, as set out by the NAO). Sizewell C: £38.2bn project baseline (2024-25 prices, NAO). A UK fleet cost: not published.
What it would deliver
Sizewell C baseline 22% below Hinkley Point C's lowest estimate, with 85% of the above-ground design replicated; about £11,650/kW against about £15,000/kW (estimate). NEA: about 15% off the second reactor of a pair and 25-40% off total costs in series construction. Barakah costs fell more than 50% between unit 1 and unit 4 (secondary source).
Documented risks
Costs fell in pairs but rose across the French national series, partly from stricter rules. Shin Kori 3 and 4 finished about 32% over the announced budget. Korean cost data are not independently audited. A US study reports later plants costing more. Delay between UK units can erode the replication benefit. The NAO and DESNZ state the benefit as reduced risk, not a quantified fall.

Carbon leakage

The government names carbon leakage as a risk and says it "is committed to tackling" it. A UK Carbon Border Adjustment Measure starts on 1 January 2027. Options on export leakage are still being assessed, and indirect emissions are in scope "delayed until 2029 at the earliest". official, DBT and HM Treasury

What it would cost
Support already in place: about £400m a year (exemption scheme) plus £310m to £420m a year (network-charge relief) plus up to £600m a year from April 2027. Total package value: not published. The cost of bringing UK prices to the EU median: not published.
What it would deliver
UK large industrial users pay 24.35 p/kWh including taxes against an EU14 plus UK median of 11.04. Support reduces steel producers' electricity from £168 to £86/MWh. A change in output is not forecast in any source read.
Documented risks
Carbon leakage is the government's own named risk; export leakage and indirect-emission coverage stay unresolved until 2029 at the earliest. Steel output fell from 10.9 Mt (2015) to 2.6 Mt (2025), with the cause shared between overcapacity and cost. The cost of support falls on other consumers.
