UK Food Safety Law for Online Sellers: A 2026 Compliance Summary
Selling food online in the UK requires compliance with food safety, labelling, and business registration requirements. Here is a 2026 summary for online food sellers.
Selling food online in the UK is subject to the same legal requirements as selling food in a physical shop. There is no online exemption from food safety law. Here is a 2026 summary of what online food sellers must comply with.
Food Business Registration
Any business that prepares, stores, distributes, or sells food must register with their local authority as a food business. Registration is free. It triggers a food hygiene inspection and places your business within the regulatory framework.
Food Labelling Requirements
Food products sold online and dispatched to consumers must carry labels compliant with the UK Food Information Regulations. Requirements include:
- Product name
- Full ingredient list with allergens emphasised
- Net quantity
- Best before or use by date
- Storage and preparation conditions
- Name and address of the food business
For products sold online, pre-sale information (including allergen data) must be available to consumers before purchase.
Food Hygiene
Food preparation must take place in premises that meet food hygiene standards. Domestic kitchens can be registered as food businesses, but they must meet the relevant standards. A 5-star food hygiene rating is the target.
Trading Standards and Labelling Accuracy
Trading Standards enforces food labelling law. Inaccurate descriptions, misleading claims, and incorrect allergen information are enforcement priorities.

Natasha's Law and the Fourteen Allergens
Natasha's Law, which came into full effect in October 2021, requires that all food produced and packed on the same premises from which it is sold must carry full ingredient labelling with allergens clearly emphasised. For online sellers, this means every pre-packed for direct sale item dispatched to a customer must display a complete ingredient list. Allergens must be highlighted in bold, italics, or a contrasting colour so they are immediately visible. There is no grace period remaining, and enforcement action is now actively taken against non-compliant businesses.
The fourteen allergens covered by UK food law are celery, cereals containing gluten, crustaceans, eggs, fish, lupin, milk, molluscs, mustard, peanuts, sesame, soybeans, sulphur dioxide and sulphites above ten parts per million, and tree nuts. Every one of these allergens must be declared if present as an ingredient or as a component of a compound ingredient. Online product pages must present this information clearly before a customer completes a purchase, meaning allergen data cannot be reserved only for the physical label on the package.
For Shopify merchants selling food products, this creates a practical challenge: product descriptions must be kept accurate and up to date, ingredient changes must be reflected immediately across the storefront, and allergen declarations must be formatted to meet the legal emphasis requirement. A manual approach to this process is prone to error and difficult to scale. Tools that embed structured allergen information directly into product pages help merchants maintain compliance without relying on manual copy updates for every listing.
Distance Selling and Pre-Sale Information Requirements
When food is sold at a distance, meaning the customer and seller are not in the same physical location at the point of sale, UK food information law requires that mandatory information is made available to the consumer before the purchase is concluded. This is not a recommendation. It is a legal obligation under the UK Food Information Regulations, which apply directly to online transactions. The pre-sale information must include the product name, allergen information, and any other mandatory details that apply to that product category. A consumer must be able to access this information before adding an item to their basket and proceeding to checkout.
In practice, this means that allergen and ingredient information must appear on the product page itself, not solely in a downloadable document linked from a footer, not only inside the packaging that arrives after the order is placed, and not in a separate FAQ section that a customer might never visit. The information must be discoverable as part of the normal purchasing journey. Regulators and enforcement bodies have made clear that burying mandatory information in a location that is technically accessible but practically obscure does not satisfy the legal requirement.
Online food sellers should audit their Shopify storefronts regularly to confirm that every product listing containing a regulated food item displays the required pre-sale information prominently. This includes checking that allergen data is present on variant-level pages where different recipes or formulations are sold under the same parent product. If a chocolate bar is available in a milk chocolate and a dark chocolate variant, and those variants have different allergen profiles, each variant must independently carry accurate allergen information visible to the customer before purchase.
Country of Origin and Provenance Claims
Country of origin labelling is a mandatory requirement for specific food categories under UK law, including fresh, chilled, and frozen beef, veal, pork, sheep, goat, and poultry meat. For these categories, both the country where the animal was reared and the country where it was slaughtered must be declared. Honey, olive oil, and certain fruit and vegetable categories also carry origin labelling requirements. Online sellers must ensure that their product listings reflect accurate origin information and that this information is kept current if supplier sourcing changes.
Beyond mandatory requirements, many online food businesses make voluntary provenance claims as part of their marketing, describing products as British, locally sourced, or made from regional ingredients. These claims are subject to Trading Standards scrutiny in the same way that any product description is. A claim that a product is made with British butter, for example, must be substantiated. If the recipe changes and the butter source changes, the product page must be updated before orders continue to be accepted. Misleading provenance claims, even unintentional ones arising from outdated copy, can result in enforcement action.
For Shopify merchants, the practical implication is that product page content should be treated as a live legal document, not static marketing copy. Any change to a recipe, supplier, or formulation triggers a labelling review obligation. Establishing a clear internal process for communicating ingredient changes from production or procurement through to the online storefront reduces the risk of a gap between what is being sold and what is being described.
Organic and Nutritional Claims
Food businesses making organic claims must be certified by an approved UK organic control body. The term organic is legally protected, and using it on a product label or online listing without valid certification is a criminal offence under UK organic regulations. Certification must be renewed and kept current. If certification lapses, all references to the product as organic must be removed from the Shopify storefront immediately, including product titles, descriptions, tags, and any collection or category pages that reference the term.
Nutritional and health claims are regulated under UK retained law derived from the EU Nutrition and Health Claims Regulation. Only claims that appear on the UK register of permitted claims may be made on food products. Claims such as high in protein, source of fibre, or supports immune health are subject to specific conditions, including minimum thresholds that the product must meet and restrictions on how the claim may be presented. Making an unauthorised health claim, even one that seems reasonable or widely used in the industry, is a breach of food law.
Online sellers should review every product description for language that could be interpreted as a nutritional or health claim and verify that any such language corresponds to a permitted claim for which the product qualifies. This is particularly relevant for functional foods, supplements positioned as food products, sports nutrition items, and products marketed to specific health-conscious audiences. The threshold for what constitutes a regulated claim is lower than many sellers assume.
Shelf Life, Date Marking, and Storage Instructions
Use by dates apply to foods that are microbiologically perishable and where spoilage could pose a health risk. Best before dates apply to foods where quality rather than safety is the primary concern after the indicated date. Online food sellers must use the correct date marking format for each product category and must not dispatch products where the use by date falls before a reasonable delivery window. Dispatching a product that will expire during transit or immediately upon arrival creates both a legal compliance issue and a significant customer service problem.
Storage instructions must be accurate and must reflect any changes in storage conditions that apply after opening. For chilled or frozen products sold online, the packaging and the product listing must both convey appropriate storage guidance so that the customer knows how to handle the product upon receipt. If a product requires refrigeration on arrival, this must be communicated at the point of sale and not left to the customer to infer from the packaging alone. Carriers used for temperature-sensitive products must be appropriate for maintaining product integrity during transit.
Date marking and storage information on a Shopify product page should be reviewed whenever a product formulation or supplier changes, as shelf life can vary between production runs or between equivalent products from different manufacturers. Food businesses that sell products with relatively short shelf lives should also consider how their fulfilment timelines interact with those shelf lives, and whether any minimum remaining shelf life guarantee needs to be communicated to customers as part of the pre-sale information.
