  • 75p price-marked wrapper, back and front supported · Compare evidence

    Read from the 1080 x 1920 px Open Food Facts photographs uploaded 2026-03-23 (imgid 3, back; imgid 4, front); the right edge of the back is outside the frame and the bracketed words are the ones it cuts. The statement matches the Bestway sheet word for word where both are legible. The back also prints a "Responsibly Sourced Cocoa 100%" badge with a QR code, a GB block with 0800 952 00[77] and a Freepost address for Mars Wrigley Co[nfectionery], and a block for Mars Foods Ireland Ltd, PO Box 3[…], https://ire.mars.com/ and an 1890 number. The front end flap prints "Mars = 51 g, 948kJ, 225kcal, 11%*" and a per-100 g energy line ending "442 kcal"; the front edge prints "Free From Artificial Colours, Flavours & Preservatives", and the yellow flash at the right end is cut by the frame. The nutrition table at the left edge of the back shows only its percentage column.

The barcode and the price flash are not legible in the photograph, so its tie to this article rests on the filing alone.

What the sources say about these ties
Mars, Incorporated owns
Wikipedia names Mars Inc. as the producer of the Mars bar since 1932.

Built from the ownership rows on the brand and company pages, each cited where it is recorded. Made in is the country of production on this product's record; the GS1 prefix of a barcode names the issuing organisation, not where the product was made.

About this product

Mars 51 g under barcode 5000159565004 is the British price-marked edition of the standard single Mars bar, its wrapper carrying a yellow 75p flash: milk chocolate (40 %) with a soft nougat (32 %) and caramel centre (27 %), the bar Forrest Mars Sr. first made in Slough in 1932.[2][3][1] One bar gives 948 kJ (225 kcal), and the recipe uses whey permeate, sunflower oil and palm fat.[3][4] The back names Mars Wrigley Confectionery on a GB consumer line.[4] Bestway Wholesale sells it in cases of 48 with a 75p RSP, and a London convenience store listed it at GBP 0.90 in September 2026.[3][5]

Better Retailing reported in April 2026 that Mars had cut its British single bars from 51 g to 40 g without changing the 75p price-mark, with a leading wholesaler showing the 51 g price-marked bar as discontinued.[6] Trade suppliers still listed this code afterwards, and Forrest Foods and Brand Factory give 5000159565011 as the code of its 48-bar case.[7][8] A 2024 photograph filed under the same barcode shows a wrapper with a football prize-draw promotion.[9]

Coverage & research gaps (13)

Coverage measures the evidence recorded here. It does not rate the product.

  • Identity: 3 / 3 · Name, brand and classification recorded
  • Context: 4 / 5 · Evidence groups assigned to a researched label, edition or analysis
  • Label photographs: 0 / 4 · Researched contexts with an assigned photograph
  • 75p price-marked wrapper, back and front: nutrient evidence: 2 / 2 · Recorded nutrient rows linked to a source; not the number of nutrients that ought to exist
  • Label data on Bestway Wholesale's product sheet: nutrient evidence: 17 / 17 · Recorded nutrient rows linked to a source; not the number of nutrients that ought to exist
  • identity · unknown: Better Retailing reported in April 2026 that a leading wholesaler showed the 75p price-marked 51 g Mars bar as discontinued, replaced by a 40 g bar with the same 75p price-mark; the report names no barcode, and no Mars range page lists either bar, so status stays open while London shops and Bestway still carried this code in September 2026.
  • markets · disputed: The back prints a consumer block for Mars Foods Ireland Ltd with an Irish 1890 number beside the GB block, as the unmarked British and Irish wrappers do, but the pack carries a sterling 75p price-mark and every listing that prints this barcode is British, so IE is not in country_of_sale.
  • nutrition · unknown: The back photograph shows only the percentage column of the nutrition table, so the full panels come from the Bestway sheet.
  • relationships · unknown: GS1's GDSN trading-partner list settles who holds the prefix but not how long it is: GLN 5000159000000 shows the holder zero-filling from the eighth digit, so 5000159 is recorded as a seven-digit prefix without a published allocation length.
  • markets · unknown: amazon.co.uk searched on 2026-09-25 for "Mars bar 51g 75p price marked", "mars" and 5000159565004 through web search, since the store answers this agent with a WAF challenge (HTTP 202, empty body). Single-bar hits B00WUJH40I and B00J3TPS1A are the older unmarked 51 g article; the rest are 24-, 35- and 48-bar boxes (B0BJHNCG72, B0DCZWT1K6, B07ML3RVPH, B003TCOJY4, B00X68EOU0), none naming the 75p price-mark or this barcode.
