Report No. 1, version 1.0.2

26 October 2026 · correction · Read this version · This version on Zenodo

Corrected one sentence on p.17 that left out how the gas-led alternative’s own gas burn moves the price it pays, and the p.18 heading, which went beyond changing one assumption at a time. No figures changed.

Each change below shows the sentence in version 1.0.1 and in version 1.0.2. Words taken out are struck through; words put in are marked.

  1. Correction p.17, “It’s gas, not policy”

    What was wrong: the sentence said the gas-led alternative pays the actual price of gas; it pays that price plus a rise for its own extra burn, or a fall in years when it burns less gas than Britain did.

    Version 1.0.1:

    The gas-led alternative pays the actual price of gas in every month, 2022 included.

    Version 1.0.2:

    The gas-led alternative pays the actual price of gas in every month, 2022 included, plus a rise for its own extra burn, or a fall in years when it burns less gas than Britain did (chapter 5).

    Effect: none on any figure. Found by: a fact-check for the author.

  2. Correction p.18, Chapter 5 heading

    What was wrong: the heading said the extra cost stays above £120bn however the main assumptions are set; only one assumption was changed at a time.

    Version 1.0.1:

    However the main assumptions are set, the extra cost stays above £120bn

    Version 1.0.2:

    Changing one main assumption at a time, the extra cost stays above £120bn

    Effect: none on any figure. Found by: a check for the author.

Report No. 1, version 1.0.1

26 October 2026 · correction · This version on Zenodo

Corrected one sentence on p.17 that had the effect of gas prices the wrong way round. Clarified the VAT basis of figures on pp.9 and 16, and the years carbon pricing led on p.16. No figures changed.

Each change below shows the sentence in version 1.0 and in version 1.0.1. Words taken out are struck through; words put in are marked.

  1. Correction p.17, “It’s gas, not policy”

    What was wrong: the sentence said a higher gas price for the gas-led alternative could add to the extra cost; it reduces it.

    Version 1.0:

    Gas could add to the extra cost in one way only: burning more gas, the gas-led alternative may pay more for it.

    Version 1.0.1:

    Gas could remove the extra cost in one way only: burning more gas, the gas-led alternative may pay more for it.

    Effect: none on any figure. Found by: the author’s own review.

  2. Clarification p.9, The answer

    What was wrong: the range £39.5bn to £60.0bn, and the £13.4bn saved over 2021–23, did not say they include VAT, next to a key number that excludes it.

    Version 1.0:

    Changing one assumption at a time, the net cost runs from £39.5bn to £60.0bn.

    Version 1.0.1:

    Changing one assumption at a time, the net cost with VAT runs from £39.5bn to £60.0bn.

    Version 1.0:

    Over 2021–23 renewables saved £13.4bn more than they cost, because the gas price, and so the price they pushed down, reached extremes.

    Version 1.0.1:

    Over 2021–23 renewables saved £13.4bn more than they cost, with VAT, because the gas price, and so the price they pushed down, reached extremes.

    Effect: none on any figure. Found by: the author’s own review.

  3. Clarification p.16, How the extra cost builds up, year by year

    What was wrong: the sentence named only 2005 and 2022 as years carbon pricing was the biggest single charge; it also was in 2006, 2008–11 and 2023.

    Version 1.0:

    Carbon pricing was the biggest single charge in 2005, at £3.3bn, and again in 2022, at £11.4bn; from 2012 to 2021 the Renewables Obligation was.

    Version 1.0.1:

    Carbon pricing was the biggest single charge in 2005, at £3.3bn, in 2006 and 2008–11, and again in 2022, at £11.4bn, and 2023; from 2012 to 2021 the Renewables Obligation was.

    Effect: none on any figure. Found by: the author’s own review.

  4. Clarification p.16, Key number

    What was wrong: the key number £82.9bn for carbon pricing did not say it is before VAT.

    Version 1.0:

    £82.9bn carbon pricing’s part of the extra cost, 2002–24.

    Version 1.0.1:

    £82.9bn carbon pricing’s part of the extra cost, 2002–24, before VAT.

Technical paper, version 1.0.1

26 October 2026 · correction · This version on Zenodo

Corrected one sentence in §3.2 that put the effect of gas prices the wrong way round. No figures changed.

Each change below shows the sentence in version 1.0 and in version 1.0.1. Words taken out are struck through; words put in are marked.

  1. Correction p.8, §3.2 The case that gas drives the cost

    What was wrong: the sentence said gas could “drive the gap” through the road paying more for its gas; a dearer gas price for the road reduces the gap.

    Version 1.0:

    Gas can still drive the gap in one way: the road burns more gas than Britain did, and so may pay more for it.

    Version 1.0.1:

    Gas can still remove the gap in one way: the road burns more gas than Britain did, and so may pay more for it.

    Effect: none on any figure. Found by: the author’s own review.
