Egg Labelling Regulations UK: Complete Guide to Egg Box Labels, Egg Stamping and Compliance

Egg labelling in the UK is governed by a detailed set of marketing standards that cover everything from the code stamped on each individual shell to the information printed on the box. Whether you are a large-scale commercial producer, a small free-range farm, or a packing centre, understanding these rules is essential to staying compliant and avoiding enforcement action.

This guide explains the full scope of UK egg labelling regulations, including producer codes, farming method marks, quality and weight grading, best before dates, egg box labelling requirements, and the exemptions available to small producers. If you produce, pack or sell hen eggs in any capacity, this is what you need to know.

Key Legislation Governing Egg Labelling

UK egg labelling is governed by several overlapping pieces of legislation. Since leaving the EU, much of the original European law has been retained as assimilated law in the UK. The key regulations are:

• Assimilated Regulation (EC) No 589/2008: The primary regulation laying down detailed rules for egg marketing standards. This covers stamping, grading, labelling, packaging, storage and transport of eggs for retail sale.
• Assimilated Regulation (EC) No 1308/2013: Establishes the common organisation of agricultural markets, including the framework for egg quality and marketing standards.
• The Eggs and Chicks (England) Regulations 2009 (SI 2009/2163): The domestic legislation covering the production process through to final sale, including stamping, labelling and permitted marketing of eggs. Equivalent regulations exist in Wales, Scotland and Northern Ireland.
• Assimilated Regulation (EU) No 1169/2011 (Food Information to Consumers): The broader food labelling legislation that applies to eggs when sold as prepacked food, covering matters such as allergen declarations and general labelling standards.

These regulations apply to hen eggs for human consumption. Eggs from other bird species fall outside the marketing standards regime but are still subject to general food labelling requirements.

Egg Stamping: The Producer Code Explained

Every hen egg sold at retail level in the UK must be individually stamped with a producer code on the shell. This code is the cornerstone of egg traceability and tells the consumer three pieces of information in a single string:

• Farming method (a single digit: 0, 1, 2, or 3)
• Country of origin (a two-letter ISO code, e.g. UK)
• Producer ID (a unique number assigned to the production site by the Animal and Plant Health Agency, or APHA)

For example, an egg stamped 1UK12345 tells you it is a free-range egg (1), produced in the United Kingdom (UK), at production site number 12345.

How the Code Breaks Down

The producer code must be clearly legible on the eggshell. British Lion eggs also carry the Lion logo and a best before date directly on the shell alongside the producer code.

Farming Method Codes: Organic, Free Range, Barn and Cage

The first digit of the producer code indicates the method of farming under which the hens were kept. There are four categories, each with specific legal criteria that must be met:

0 – Organic

Organic eggs are always free range. In addition to meeting all free-range requirements, hens must be fed an organically produced diet and ranged on organic land. The hen house conditions are set by organic regulations, with a maximum stocking density of 6 hens per square metre of usable area and a maximum flock size of 3,000 birds. Organic certification must be obtained from an approved body such as the Soil Association.

1 – Free Range

Free-range hens must have continuous daytime access to outdoor ranges that are mainly covered with vegetation. The outdoor stocking density must not exceed 2,500 hens per hectare (equivalent to 4 square metres per bird). Hen houses must provide at least one nest for every seven hens (or appropriate nest space), perches, and a maximum indoor stocking density of 9 hens per square metre. Pop-holes must be provided allowing the hens to move freely between the house and the range.

2 – Barn

Barn hens are kept indoors but are free to roam within the hen house. The maximum stocking density is 9 hens per square metre of usable floor area. The house must provide nest boxes, perches, and litter covering at least one-third of the floor area. Barn hens do not have outdoor access.

3 – Cage (Enriched Colony)

Since January 2012, conventional battery cages have been banned across the UK. Caged hens must now be kept in enriched colony cages that provide at least 750 square centimetres per bird, along with a nest box, perching space, scratching area, and unrestricted access to a feeding trough. Each colony typically contains between 40 and 80 birds. If eggs have not been produced in accordance with the standards for organic, free-range or barn production, they are automatically classified as eggs from caged hens.

These farming method descriptions must be used accurately. Using the term “free range” on eggs that do not meet the legal criteria is an offence under the marketing standards regulations.

Quality Grading: Class A and Class B Eggs

Under UK and assimilated EU law, there are two quality grades for eggs:

Class A (Fresh Shell Eggs)

Class A is the highest grade and the only grade sold as shell eggs to consumers. To qualify as Class A, an egg must meet specific quality criteria:

• Shell must be clean, undamaged and intact with normal shape
• Air cell must not exceed 6mm in depth (the air space at the blunt end of the egg)
• Egg white must be clear and translucent with a gelatinous consistency
• Yolk must be visible only as a shadow on candling, without clearly discernible outline, and must not move significantly away from the centre of the egg when rotated
• The germ must show no development
• No foreign matter or odour must be present

Class A eggs must not have been washed or cleaned (other than dry cleaning), treated, refrigerated below 5 degrees Celsius, or preserved. They can only be graded at an authorised packing centre.

Class A “Extra” or “Extra Fresh”

Packs of Class A eggs may be labelled as “extra” or “extra fresh” up to nine days after laying. After this date, the “extra” labelling must be removed. The air cell must not exceed 4mm in depth for eggs carrying this description.

Class B (Industrial Eggs)

Class B eggs do not meet Class A standards. They cannot be sold as shell eggs to consumers and are instead broken out, pasteurised and sold to the food manufacturing industry for use in products such as cakes, mayonnaise and pasta. Class B eggs may also be used in non-food products like cosmetics and shampoo.

Weight Grading: Egg Size Categories

Class A eggs must be weight-graded and sold in one of four size categories. No other terms may be used to describe egg sizes at retail:

Eggs may also be sold as mixed weight, but this must be clearly stated on the packaging. Large and Medium are by far the most common grades in UK retail, accounting for approximately 88% of all eggs sold.

Egg Box Labelling Requirements

The egg box label carries a significant amount of mandatory information. For prepacked Class A eggs sold at retail, the following must appear on the outer packaging:

Mandatory Information on Egg Boxes

• Packing centre number: The registered identification number of the packing centre that graded and packed the eggs, supplied by APHA. This is distinct from the producer code on the eggs themselves.
• Quality grade: “Class A” or the equivalent marking
• Weight grade: Very Large, Large, Medium, Small or Mixed Weight
• Number of eggs: The pack size declaration
• Best before date: No more than 28 days after laying
• Farming method: The method of production (organic, free range, barn, or eggs from caged hens), which must correspond to the number code stamped on the eggs
• Egg stamping explanation: A statement explaining the producer code printed on the eggs, typically formatted as: “Egg Stamping Explanation: 0 = Organic, 1 = Free Range, 2 = Barn, 3 = Caged, UK = Origin, followed by Producer ID”
• Storage advice: A printed instruction telling consumers to keep eggs refrigerated after purchase
• Name and address: The business name and address of the packer or the person who arranged for the eggs to be packed

Additional Permitted Information

In addition to the mandatory elements, egg boxes may include optional information such as the date of laying, a sell-by or display-until date (for stock control), assurance scheme logos (Lion Quality, RSPCA Assured, Soil Association), barcodes for retail scanning, and the producer or farm name for marketing purposes.

At PID Labelling, we produce custom egg box labels that incorporate all required information in a clear, professional design. Our labels can include your branding, logos, barcodes and full regulatory information in the correct format.

Labelling Requirements for Loose Eggs

Eggs sold loose in trays at retail (rather than in closed packs) must be accompanied by the same information as packed eggs, but it may be displayed on a notice or sign near the point of sale rather than on the tray itself. The loose eggs must still be individually stamped with the producer code, and the information displayed must include the quality grade, weight grade, farming method, best before date and a statement explaining the egg stamping code.

Best Before Dates and Sell-By Rules

Eggs have specific date-marking rules that are more prescriptive than for most other foods:

• Best before date: Must be no more than 28 days after the date of laying. This is a mandatory requirement for all eggs, whether packed or sold loose. The format must read “best before” followed by the day and month (you may optionally add the year).
• Sell-by deadline: Retailers must sell or remove eggs from display within 21 days of laying. There is no legal requirement to show a sell-by date on the packaging, but many retailers and producers include one for stock management purposes.
• Delivery to retailers: Eggs must be delivered to the retailer within 21 days of laying.
• Collection from producers: Ungraded eggs must be collected from the producer within 10 days of laying.

British Lion eggs also carry the best before date stamped directly on the eggshell alongside the producer code, providing an additional layer of consumer information. Where no sell-by date is shown on the box, best practice is to remove eggs from sale seven days before their best before date.

The British Lion Quality Code

The British Lion Quality Code of Practice is the most widely recognised egg assurance scheme in the UK, covering over 90% of all eggs produced in the country. While not a legal requirement, the Lion scheme sets standards that go beyond the minimum legal requirements and has been instrumental in virtually eliminating salmonella from UK eggs.

What the Lion Mark Means

Eggs and packs bearing the red Lion logo have been produced under a strict code of practice managed by the British Egg Industry Council (BEIC). Key requirements of the scheme include:

• Mandatory vaccination of all laying hens against salmonella
• Enhanced hygiene controls and regular salmonella testing throughout the production chain
• Best before dates stamped on each individual eggshell
• Full traceability from farm to pack
• Feed produced to Universal Feed Assurance Scheme (UFAS) standards
• Independent auditing to ISO 17065 accreditation standards

The Lion scheme is the reason that the Food Standards Agency updated its advice in 2017 to confirm that British Lion eggs are safe to be eaten runny or raw by vulnerable groups, including pregnant women, babies and elderly people. This was a significant milestone in food safety.

Other Assurance Schemes

While the Lion mark is dominant, other assurance schemes are available for producers who may not be part of the Lion scheme:

• Laid in Britain: A food safety and hen welfare assurance scheme run by the UK Egg Producers Association (UKEP), designed specifically for independent egg producers, packers and retailers.
• RSPCA Assured: A welfare-focused scheme (formerly Freedom Food) covering all production systems with an emphasis on animal welfare standards.
• Soil Association: The leading organic certification body, relevant for producers seeking organic status for their eggs.

Small Producer Exemptions: Farm Gate and Market Sales

The regulations recognise that small-scale egg producers operate differently from commercial operations and provide specific exemptions. The rules depend on the size of your flock and how you sell your eggs.

Producers with Fewer than 50 Hens

If you have fewer than 50 laying hens and sell eggs directly to consumers (from your farm gate, door-to-door, or at local markets), you benefit from the most relaxed requirements:

• You do not need to register with APHA as an egg production site
• You are exempt from stamping eggs with a producer code, but you must display your name and address on a notice at the point of sale
• You cannot use weight grades (Large, Medium, etc.) or quality grades (Class A) on your eggs
• You must still provide a best before date (no more than 28 days from laying)
• You must still include a statement advising consumers to keep eggs refrigerated after purchase
• You should register voluntarily with the GB Poultry Register for disease control purposes

Producers with 50 or More Hens Selling Directly

If you have 50 or more hens and sell eggs at farmers markets, car boot sales, or similar local public markets, you must register with APHA as an egg production site. APHA will issue you with a producer code, which must be stamped on every egg you sell. You must also register with the GB Poultry Register for disease control.

However, if you have fewer than 350 hens and sell all your eggs directly to consumers at your farm gate or by door-to-door delivery, you do not need to register with an APHA Egg Marketing Inspector (EMI).

Selling on Your Own Premises

There is a further exemption for eggs sold on the premises where they were produced. In this case, the eggs do not need to be weight-graded or stamped with any information. However, a best before date must still be given. This is the simplest scenario and applies to true farm-gate sales where the customer comes to you.

What Small Producers Cannot Do

Regardless of flock size, eggs sold directly to consumers (rather than through retail) cannot be advertised with weight grades or quality grades unless they have been graded at an authorised packing centre. You cannot label your farm-gate eggs as “Large” or “Class A” unless you are registered as a packing centre. You also cannot sell directly to shops, restaurants or catering businesses without grading your eggs at a registered packing centre first.

Registration and Inspection Requirements

The registration requirements for egg producers vary depending on the scale of operation and the sales channel:

APHA Registration

• Egg production sites: Any premises producing eggs for sale must register with APHA (except the sub-50-bird exemption described above). Registration is free and provides you with a producer code.
• Egg packing centres: To sell eggs to retailers, caterers or restaurants, you must register as a packing centre with APHA. Only registered packing centres can grade eggs as Class A.
• GB Poultry Register: All keepers of 50 or more birds of any species must register with the GB Poultry Register for disease control purposes. Keepers of fewer than 50 birds are encouraged to register voluntarily.

Inspections

APHA Egg Marketing Inspectors (EMIs) are responsible for inspecting all registered premises in England and Wales where hen eggs are produced, graded, packed, imported or sold. They ensure that eggs meet marketing standards, checking egg stamping, labelling, grading, storage conditions and record keeping. Producers with 350 or more laying hens must also carry out environmental sampling for salmonella and keep the results available for inspection.

Avian Flu and Free-Range Labelling

Outbreaks of highly pathogenic avian influenza (bird flu) have caused significant disruption to egg labelling in recent years. When DEFRA issues mandatory housing orders requiring free-range flocks to be kept indoors to protect them from disease, the legal status of their eggs is affected.

Previously, the regulations allowed a 16-week derogation period during which eggs from housed free-range flocks could continue to be labelled as “free range”. After 16 weeks, the eggs had to be reclassified and labelled as “barn” eggs, causing significant additional cost and disruption to producers who needed to change all their egg packaging and labelling.

In both the 2021-22 and 2022-23 outbreaks, the housing orders exceeded this 16-week period by several weeks. Following industry lobbying and a government consultation, the UK government announced in 2024 that it would amend the regulations to remove the 16-week derogation period entirely for England and Scotland. This means free-range eggs can continue to be labelled as such throughout any mandatory housing measure, removing the need for costly relabelling during bird flu outbreaks.

This is a welcome change for producers. At PID Labelling, we have direct experience of this issue, having produced millions of additional advisory labels during previous avian flu outbreaks to help egg producers comply with the temporary reclassification requirements.

Eggs from Other Species

The egg marketing standards regulations apply only to hen eggs. Eggs from other species such as ducks, quail, geese and guinea fowl are not subject to the same marketing standards regime. However, they must still comply with general food labelling requirements, including:

• The species of bird must be clearly stated (e.g. “duck eggs”, “quail eggs”)
• A best before date must be provided
• The name and address of the producer or packer must be shown
• Any allergen declarations must comply with the Food Information to Consumers regulation

Non-hen eggs do not need to be stamped with a producer code, weight-graded or quality-graded under the marketing standards. However, they must still be safe and accurately described.

Eggs as an Allergen: Labelling in Food Products

Egg is one of the 14 major allergens that must be declared on food labels under UK law. This applies not to eggs sold in their shell, but to eggs used as an ingredient in other food products such as cakes, pasta, mayonnaise, sauces, battered products and many other items.

When eggs are used as an ingredient, the word “egg” must be emphasised in the ingredients list, typically in bold text. This applies to all forms of egg including whole egg, egg white, egg yolk, egg powder and any ingredient derived from eggs. For detailed guidance on allergen labelling requirements, see our dedicated guide.

Businesses preparing food containing eggs for direct sale (such as bakeries and sandwich shops) must also declare the presence of eggs, either on the label or through clear signage, in accordance with Natasha’s Law for prepacked for direct sale (PPDS) foods.

Common Egg Labelling Mistakes to Avoid

• Using weight grades without authorisation: Only eggs graded at a registered packing centre can be described as Large, Medium, etc. Small producers selling directly cannot use these terms unless they are registered as a packing centre.
• Missing the best before date: This is mandatory for all eggs regardless of the scale of production or sales channel. There is no exemption from this requirement.
• Incorrect farming method claims: Describing eggs as “free range” when the hens do not have outdoor access meeting the legal criteria is an offence. If your hens do not meet free-range or barn standards, the eggs must be classified as cage eggs.
• Missing storage advice: Egg packs must include a printed instruction telling consumers to keep eggs refrigerated after purchase.
• No egg stamping explanation: Your egg box label must include a statement explaining the producer code system to consumers.
• Selling beyond 21 days: Retailers must remove eggs from sale within 21 days of laying, even if the best before date has not yet been reached.
• Selling direct to trade without grading: You cannot supply eggs to shops, restaurants, or catering businesses unless the eggs have been graded at a registered packing centre.
• Not registering with APHA: If you have 50 or more hens and sell eggs at public markets, registration is compulsory, not optional.

Frequently Asked Questions

Do I need to stamp my eggs?

If you sell eggs at retail (in shops or through packing centres), yes, every egg must be stamped with the producer code. If you sell directly to consumers with fewer than 50 hens, you are exempt from stamping but must display your name and address. If you sell only from your own premises where the eggs are produced, no stamping is required.

Can I sell eggs from my garden at a farmers market?

Yes, but the requirements depend on your flock size. If you have fewer than 50 hens, you do not need to register with APHA or stamp your eggs, but you must display your name and address, provide a best before date, and include a refrigeration statement. With 50 or more hens, you must register with APHA and stamp the eggs with your producer code. In either case, you cannot use weight grades or quality grades.

What best before date should I put on my eggs?

The best before date must be no more than 28 days from the date of laying. It must be written in the format “best before” followed by the day and month, with the year being optional. For example: “Best before 15 MAR” or “Best before 15/03/2026”.

Can I wash my eggs before selling them?

Class A eggs must not be washed or cleaned with wet methods. Washing removes the natural protective coating (cuticle) on the shell, which increases the risk of bacterial contamination. If eggs are dirty, they can be dry-cleaned, but wet-cleaned eggs cannot be sold as Class A. Only sell clean, intact eggs.

Do duck eggs, quail eggs or goose eggs need to follow the same rules?

No. The egg marketing standards apply only to hen eggs. Eggs from other species must follow general food labelling rules including a best before date, the species name, and producer details, but they do not need producer code stamping, quality grading or weight grading.

What does the Lion mark mean on an egg?

The red British Lion mark indicates the egg has been produced under the Lion Quality Code of Practice, which covers over 90% of UK egg production. It guarantees the hen was vaccinated against salmonella, the egg has been produced to standards exceeding legal requirements, and the best before date is stamped directly on the shell. Lion eggs are confirmed safe to eat runny or raw by the Food Standards Agency.

Can I sell eggs to a local shop or restaurant?

To sell eggs to any trade customer (shops, restaurants, caterers), the eggs must be graded at a registered packing centre. You cannot supply ungraded eggs to trade outlets. You would either need to register your own premises as a packing centre with APHA or supply your eggs to an existing packing centre for grading before sale.

How do I register as an egg producer?

Contact APHA directly. In England, email CSCOneHealthEggMarketing@apha.gov.uk or call 03000 200 301. Registration is free. You will be issued a producer code for your premises, which must be stamped on your eggs. You must also register any flock of 50 or more birds on the GB Poultry Register for disease control purposes.
