Data Sources & Price Verification Methodology
Complete provenance of our Greggs menu data: official nutritional guides, shop-level Click + Collect captures, and verification standards.
Quick answer: nutrition figures come from Greggs' own published documents; prices come from the public Greggs Click + Collect menu for named shops (Central London, a Sheffield high-street shop and a forecourt unit), with the method disclosed wherever a figure is estimated.
Official nutritional and allergen documentation
All calorie counts, macronutrient figures (protein, carbohydrates, fat, saturated fat, sugar), and allergen declarations are mapped directly from published Greggs plc nutritional documents and allergen guides.
Store-specific Click + Collect price captures
Prices displayed on GreggsMenus are read from the public Greggs Click + Collect menu (before checkout, no login) for three named shops: 94 Great Portland Street, London (14 September 2026), 100 The Moor, Sheffield (21 September 2026) and an EG On The Move forecourt unit in Rotherham (21 September 2026). Because Greggs does not publish a single nationwide master price list, store and channel provenance is preserved for every record.
Transparency on unpriced and seasonal items
Items that were not actively available on the digital ordering channel at the time of capture (such as off-peak breakfast items or regional bakery variations) show 'no online price published' rather than an invented figure. Where we estimate a price from other shop types, it is labelled with a ≈ sign and the method, and it is never used in structured data.
Discrepancy and reformulation reporting
Where published nutritional PDFs differ from digital order listings (such as the Chicken Bake 420 kcal vs 426 kcal variance), our catalogue notes the conflict transparently so consumers can verify against in-store packaging.
