£41 billion a year to rejoin the EU? What the upper 2028 estimate counts
REPRODUCE THIS INVESTIGATION

Repeat the reported-range and definition checks below. The downloadable arithmetic uses the three published rounded figures. It does not reproduce or verify the original Bow Group model.
You will need: A browser, a PDF reader, a calculator and a spreadsheet app for the optional CSV. No account or paid software is needed for the arithmetic. Instagram access may require sign-in.

ACCESS AND DATA LIMITS
The original Bow report, annexes and workbook are unavailable to this investigation, so the model cannot be reproduced. Full reel audio was not heard or transcribed. This guide checks reported values and official context; it does not establish a net 2028 payment, a probability range or the overall economic effect. Evidence was checked on 16 October 2026.

1. Check what the original post actually qualifies
Open the GB News reel dated 15 October 2026. Inspect its caption and, if accessible, the chart headed as an estimated annual gross 2028 contribution without a rebate. The inspected frame gives lower 28, central 34 and upper 41 in £ billion. No exact frame timestamp was established.
Keep in mind: We inspected the caption and one chart frame, not the complete spoken reel. Do not claim the video omitted qualifications throughout.

2. Recover the attributed estimates from the publisher
In Georgia Pearce’s 15 October article, locate the paragraphs describing annual gross contributions, the central scenario, an enlarged income base and illustrative figures. The expected sterling values are 28, 34 and 41 in £ billion for 2028. The reporting is not the original Bow model.
Keep in mind: In the saved original HTML the relevant global paragraph positions are 14, 15, 20, 23 and 24. Navigation and embeds may change visible counts; use the subjects above rather than assuming the page layout is fixed.

3. Repeat the limited arithmetic
Open the downloadable scenario-arithmetic CSV. Keep unit GBP billion, annual period 2028, gross basis and no-old-rebate assumption. Read the lower, central and upper inputs as 28, 34 and 41. Subtract first, then divide by the central value and multiply by 100. Round the percentage to one decimal place.
41 - 34 = 7 (£ billion)
(41 - 34) / 34 × 100 = 20.588235…% ≈ 20.6%
41 - 28 = 13 (£ billion)
Keep in mind: The inputs were already rounded. This checks descriptive arithmetic only; there is no probability denominator, household denominator, person count or unobserved source model.

4. Read the proposed spending ceilings in their own units
Open COM(2025) 571 ANNEX, PDF page 3 / printed page 1. In the current-price table select calendar 2028 and distinguish commitments from payments. Entries are EUR million: 269,463 and 269,964. Divide by 1,000 to obtain €269.463bn and €269.964bn. These are EU-27 framework ceilings.
EUR million / 1,000 = EUR billion
Keep in mind: The same page also gives 2025 prices. Do not mix those rows or treat the seven-year 1.26% GNI measure as a uniform UK call rate.

5. Check the latest negotiation status
Read ST 13922/26, paragraph 139 on PDF page 50 and the comparison annex on PDF page 51. Bracketed correction options are unresolved. Then read paragraphs 34 and 35 of the 16 October 2026 European Council conclusions: negotiations continue with an aim of agreement before the end of 2026.
Keep in mind: A proposal, ceiling or target agreement date is not an adopted framework or an agreed UK invoice. Access errors affected local preservation of the conclusions, although the official page was read.

6. Reproduce the historical definition example
Open Treasury’s 2020 statement, Table 3.A on PDF page 16 / printed page 12. Select the 2019 outturn column, not the estimated 2020 column. Values are calendar-year cash £ million: before-rebate gross 18,946, rebate 4,516, after-rebate gross 14,430, public receipts 5,022 and net public 9,408. Divide by 1,000 for the article table in £ billion.
18,946 - 4,516 = 14,430 (£ million)
14,430 - 5,022 = 9,408 (£ million)
Keep in mind: This public-sector net definition omits direct EU payments to private recipients. For estimated 2020 retain the published 12,583 net, not 12,582 from rounded components. Old net figures cannot refute a future gross scenario.

7. Separate revenue methods from ceilings and economic effects
Read COM(2025) 574 Article 3, PDF pages 12 to 14, and COM(2026) 365 section 3 / Table 4 on PDF pages 10 to 11 and 20 to 21. Check that GNI revenue balances other resources rather than applying the headline budget percentage uniformly. Read ECA paragraphs 9 to 12, PDF page 8, on national-budget costs. Finally compare the Commons Library’s direct budget and wider-economic distinction.
Keep in mind: Do not add overlapping fees to the membership total, subtract all new resources as free revenue, calculate an unverified GDP ratio or claim a wider economic verdict. The missing original model must arrive before its assumptions can be tested.
