Batch Tracking for Small UK Food Producers: What the Law Requires
Published 15 March 2026
Environmental health will ask — can you answer?
You get a message from your local authority environmental health officer. A customer has reported a reaction. They want to know: what ingredients went into the product, which supplier lots were used, and who else bought items from the same batch.
If your batch records are a notebook with half-legible entries and a drawer of invoices, this is a stressful afternoon. If you have a simple batch tracking system, it takes five minutes.
UK food law requires traceability records. This isn't optional and it applies to every food business involved in small batch manufacturing — including sole traders selling jam at farmers markets and bakers shipping sourdough via Etsy.
What UK law actually requires
The core legal requirement comes from Regulation (EC) No 178/2002 (retained in UK law after Brexit), specifically Articles 18 and 19. The Food Standards Agency (FSA) enforces these requirements through local authority inspections.
The rules can be summarised as "one step back, one step forward":
- One step back: You must be able to identify who supplied each ingredient you used
- One step forward: You must be able to identify who you sold your products to (business customers — not individual consumers for direct retail)
For batch traceability specifically, you must be able to link finished products to the ingredients that went into them. If there's a safety problem with an ingredient, you need to identify which of your products are affected and pull them from sale.
What this means for a small food producer:
- Record which ingredients went into each production batch
- Record the supplier and, where available, the lot/batch number of each ingredient
- Record when each batch was produced
- Record where each batch was sold or distributed
- Keep records accessible — inspectors can request them at any time
- Retain records for a reasonable period — the FSA recommends at least the shelf life of the product plus 12 months as best practice
What a batch record should contain
There's no legally mandated format. A paper notebook is technically compliant — as long as it contains the right information and you can find it when asked. In practice, the simpler your system, the more likely you'll actually use it.
Each batch record should include:
| Field | Example | Why it matters |
|---|---|---|
| Batch number | CB-2026-047 | Unique identifier — links everything together |
| Product name | Seville Orange Marmalade (340g) | Which product this batch produced |
| Production date | 15 March 2026 | When the batch was made |
| Batch size / yield | 36 jars (34 passed QC) | How many units, including any rejects |
| Ingredients used | Seville oranges 4kg, sugar 3kg, lemon juice 100ml | Every ingredient in the batch |
| Supplier lot numbers | Oranges: SO-2401, Sugar: TS-0892 | Links your batch to the supplier's batch |
| Supplier names | County Fruit Wholesale, Tate & Lyle (via Booker) | One step back — who supplied what |
| Best before / use by | March 2027 (12 months from production) | Shelf life for food products |
| Distribution | 18 × Etsy orders, 12 × Farmers Market 22 Mar, 4 × stock | One step forward — where the batch went |
| Notes | 2 jars failed seal check — discarded | Quality issues, deviations from recipe |
Allergen tracking: the extra layer for food producers
If you produce food, the Food Information Regulations 2014 require you to declare 14 named allergens on pre-packed food. Since October 2021, this extends to pre-packed for direct sale (PPDS) — the brownies you wrap and label for the farmers market, the granola bags you sell via Etsy.
The 14 allergens are: celery, cereals containing gluten, crustaceans, eggs, fish, lupin, milk, molluscs, mustard, tree nuts, peanuts, sesame, soybeans, and sulphur dioxide (at levels above 10mg/kg or 10mg/litre).
Batch tracking and allergen tracking overlap. If your batch record lists every ingredient with its allergen status, you can:
- Generate accurate allergen declarations per product
- Trace which batches are affected if a supplier notifies you of undeclared allergens in their ingredient
- Demonstrate compliance during inspections
Practical tip: When entering a new ingredient into your system, immediately note its allergen status. Don't wait until labelling time — by then you'll have 20 recipes to cross-reference.
How small batch manufacturing works in practice
Batch manufacturing — producing a fixed quantity of identical products in a single production run — is how most artisan businesses operate. You make a batch of 24 candles, not one candle at a time. You bake 48 loaves, not one.
This approach has natural advantages for traceability:
- Every unit in a batch shares the same ingredients. If there's a problem with one candle from batch #47, every candle from batch #47 is potentially affected — and you know exactly what went in
- Batch numbers create a clean audit trail. From batch number → ingredients → supplier lots → distribution, everything chains together
- Recall scope is limited. If a supplier alerts you to a problem with lot SW-2401, you check which batches used that lot and recall only those — not your entire stock
The downside: batch tracking adds admin. Every production run needs a record. This is where most small producers cut corners — and where inspections find gaps.
Setting up batch tracking: the minimum viable system
You don't need software to start. Here's a system that works for any producer with fewer than 20 batches per month:
1. Choose a batch numbering convention. Keep it simple: year-sequential (2026-001, 2026-002...) or product prefix + sequential (SC-001 for soy candles, SB-001 for soap bars). The only rule: every batch gets a unique number.
2. Create a batch log. A single spreadsheet or notebook with one row per batch, containing the fields listed above. If using a spreadsheet, one tab per month keeps it manageable.
3. Record as you produce — not after. The most common failure is "I'll write it up later." You won't. Record the batch number, date, and ingredient lot numbers during production, while the ingredient containers are still in front of you.
4. Link sales to batches. When you pack orders, note the batch number on the packing slip or in your order management system. For market sales, record which batches you took and how many units returned.
5. Keep supplier invoices accessible. You need to trace ingredients back to suppliers. A folder (physical or digital) of supplier invoices, sorted by date, gives you the "one step back" link. Highlight lot numbers on invoices when they arrive.
When paper stops working
Paper batch tracking works until it doesn't. The breaking points are predictable:
- You produce more than 5 products with overlapping ingredients. Cross-referencing which batches used a particular ingredient lot becomes a manual nightmare
- You get a wholesale enquiry that requires consistent cost and traceability data. Wholesale buyers and retailers increasingly require documented batch traceability as a supplier condition
- An inspector asks for records and you can't find them quickly. "I know it's in this notebook somewhere" is not a confidence-building answer
- You need to do a voluntary recall. Tracing a single ingredient lot across months of production, through multiple products and sales channels, by hand, under time pressure — this is where paper fails catastrophically
At this point, moving to a digital system — whether a structured spreadsheet or dedicated production software — saves time and reduces compliance risk.
Batch tracking checklist for UK food producers
- Unique batch number for every production run
- Complete ingredient list with quantities per batch
- Supplier name and lot number for each ingredient
- Production date and batch yield (including rejects)
- Distribution record — where each batch was sold
- Allergen status per ingredient (food producers)
- Records retained for shelf life + 12 months (FSA best practice)
- System accessible and retrievable within a reasonable time
The practical takeaway
Batch tracking is one of those tasks that feels like pure admin — until the day you need it. Start with the minimum: a numbered batch log, ingredient lot numbers recorded during production, and a distribution note per batch. Build the habit before you build the system.
If you're producing fewer than 20 batches per month across a handful of products, a well-maintained spreadsheet is compliant and workable. When the volume or product range outgrows that, consider dedicated production management that links recipes, ingredients, batches, and sales in one place.
