Allergy-friendly catering has become a widely used phrase in the London food industry. It appears on menus, in catering proposals, and on websites. The problem is that it means something very different depending on which caterer is using it — and the difference can, in the most serious cases, be the difference between a safe meal and a medical emergency.
This guide explains what genuine allergy-friendly catering involves, what questions to ask before booking any caterer, and why kitchen standards matter far more than menu claims.

The 14 Mandatory UK Food Allergens
UK food law requires that 14 specific allergens are declared whenever they are used as ingredients in food. These are: celery, cereals containing gluten (including wheat, rye, barley, and oats), crustaceans, eggs, fish, lupin, milk, molluscs, mustard, peanuts, sesame, soybeans, sulphur dioxide and sulphites, and tree nuts.
These 14 allergens cover the vast majority of serious allergic reactions to food in the UK. For any caterer supplying food to an office or event, understanding and accurately declaring these allergens is not optional — it is a legal requirement under Natasha's Law, which came into force in October 2021 and requires full ingredient labelling on all pre-packaged food. Read our complete guide to the 14 UK food allergens for detailed information on each one.
Vanda's Kitchen labels every item with full allergen information. Our kitchen is 100% nut-free (covering both peanuts and all tree nuts) and certified halal, and we manage all remaining allergens with documented kitchen protocols and clear labelling on every product.
Allergy-Friendly vs Allergen-Safe: Understanding the Difference
Allergy-friendly typically means that a caterer is aware of allergens and tries to accommodate them. Allergen-safe means that kitchen infrastructure — physical separation, dedicated equipment, documented cleaning protocols, supply chain verification — prevents cross-contamination at a structural level.
For mild intolerances, allergy-friendly may be sufficient. For serious allergies — particularly peanut and tree nut allergies, where anaphylaxis is possible at trace exposure — only allergen-safe provision is adequate. The distinction matters most in a corporate catering context, where an individual cannot fully control their environment and depends on the caterer's kitchen practices for their safety.
When evaluating a caterer's allergen claims, the questions that matter are: Is the allergen-free status guaranteed at kitchen level or only at menu level? Is cross-contamination prevention built into the kitchen infrastructure or managed through careful individual preparation? Has the kitchen been independently assessed for food hygiene and allergen management?
Natasha's Law and Corporate Catering Compliance
Since Natasha's Law came into force, any food business producing pre-packaged food for direct sale must provide full ingredient and allergen information on the label. For corporate caterers, this means that every individually packaged item — every sandwich, every tray, every snack portion — must carry complete allergen labelling.
Non-compliance with Natasha's Law is not a technicality — it is a failure of the duty of care that food businesses owe to people with allergies. Natasha Ednan-Laperouse, for whom the law is named, died from an allergic reaction to a product that was not labelled with its allergen content. The law exists because inadequate labelling kills people.
Vanda's Kitchen complies fully with Natasha's Law. Every item we produce for delivery or collection is labelled with complete ingredient and allergen information. This is not a burden we manage — it is a standard we built our production processes around from the outset. Read more about Natasha's Law and what it means for food businesses.
Managing Multiple Allergens in One Office
The reality of corporate catering in a diverse London office is that you are rarely managing one dietary requirement. A team of thirty might include someone with a peanut allergy, a coeliac, a dairy-free employee, a person with a sesame allergy, and several who observe halal — all needing to eat the same catered lunch.
Managing this with a single caterer requires that caterer to have genuine, verified competency across all these requirements — not a menu that happens to cover them all, but a kitchen that handles them all safely. This is the standard Vanda's Kitchen is built around. Our 100% nut-free kitchen eliminates the most dangerous cross-contamination risk. Our full allergen labelling covers all remaining requirements. Our halal certification covers all food preparation. The result is catering that works for everyone at the table, without anyone needing to make a special request or eat a different meal. See our guide to catering for dietary requirements for more detail.
Gluten-Free Catering as Part of an Allergy-Friendly Offer
Coeliac disease affects approximately 1% of the UK population, with a further significant proportion experiencing non-coeliac gluten sensitivity. For a London office of a hundred people, this means at least one employee is likely to have a genuine medical need for gluten-free food, and several more may prefer it.
Genuine gluten-free catering, like nut-free catering, requires kitchen management rather than menu management. Gluten cross-contamination from shared surfaces, shared baking equipment, and airborne flour can cause symptoms in coeliacs even when the visible dish contains no gluten. Our complete guide to gluten-free catering in London covers the standards involved and how to evaluate a caterer's gluten-free provision.
Allergy-Friendly Catering for Corporate Events and Celebrations
Corporate events — whether formal client dinners, team celebrations, training days, or cultural observances — require catering that is both high quality and genuinely inclusive. The allergen management challenge intensifies at events because guest lists may include external clients and visitors whose dietary requirements are less well known than those of regular employees.
The most reliable solution is to work with a caterer whose baseline output is already allergen-safe — so that the default option is safe for the widest possible range of guests, rather than a safe option being offered alongside a standard option. Vanda's Kitchen's catering defaults to nut-free, halal, and fully labelled. The starting point is already the safest point. Read our guide to event catering in London for more on managing dietary requirements at larger occasions.
The Employer's Duty of Care
Employers have a legal and ethical duty of care that extends to the food provided in the workplace. Providing catering that excludes or endangers employees with dietary requirements is not a grey area — it is a failure of that duty. An employee with a severe nut allergy who cannot safely eat the food provided at a team lunch is being excluded from a team activity. An employee who has an allergic reaction to incorrectly labelled catered food has grounds for a formal complaint and potentially legal action.
Working with a caterer that takes allergen management seriously eliminates this risk. Vanda's Kitchen's 100% nut-free kitchen, full allergen labelling, and 5-star hygiene rating are not marketing claims — they are the substantive measures that make our catering genuinely safe. For more on employer responsibilities, read our employer's guide to food allergies in the workplace.
Allergen Management in Practice: What Good Looks Like
Good allergen management includes documented supplier verification confirming ingredients are free of stated allergens at source, physical kitchen separation where relevant (dedicated preparation areas, dedicated equipment, and cleaning protocols that prevent cross-contact), staff training covering all 14 mandatory allergens, clear labelling on all finished products that accurately reflects both ingredients and cross-contamination risks, and a complaint and incident reporting process that identifies and addresses allergen management failures. Vanda's Kitchen operates with all of these in place. Our 5-star food hygiene rating confirms that our kitchen practices have been independently assessed. Our Natasha's Law compliance confirms that our labelling meets current legal requirements.
Allergen Information and Employee Confidence
Clear, accurate allergen information does something beyond safety — it gives employees with dietary requirements the confidence to participate fully in workplace food culture without anxiety. An employee who reads a complete ingredient list and recognises that the food is safe for them is in a completely different psychological position from one who is guessing, asking questions, or declining food to be cautious. This confidence matters for the social function of workplace food. Shared meals and team lunches are social occasions as much as nutritional ones. Employees who cannot participate without anxiety are socially excluded in a small but real way — and that exclusion accumulates. Vanda's Kitchen's full allergen labelling on every product is designed to provide exactly this confidence. Every item carries complete ingredient and allergen information, every time, without exception.
Working With Vanda's Kitchen on Complex Allergen Requirements
If your office has complex allergen requirements — multiple allergies across a team, a colleague with a severe allergy, or an event guest list where dietary information is incomplete — we can discuss this before you order. Our catering team is experienced in translating specific allergen requirements into practical ordering decisions. We do not treat allergen discussions as a burden — they are a normal and important part of what we do, and handling them well is one of the core reasons our clients choose us and stay with us. WhatsApp us or send an enquiry and we will discuss your requirements in detail.
Seasonal and Cultural Dietary Requirements in Corporate Catering
Beyond permanent allergen requirements, corporate catering increasingly needs to accommodate seasonal and cultural dietary variations. During Ramadan, Muslim employees fast during daylight hours — changing what is appropriate for a working lunch in ways that go beyond halal certification. During various religious observances, different communities may have additional dietary restrictions — no meat on certain days, specific preparation requirements, fasting periods that affect what food is appropriate.
Truly allergy-friendly corporate catering in a diverse London office acknowledges these dimensions as well as the clinical allergen requirements. It requires a caterer with genuine cultural knowledge, not just a menu that lists allergens. Vanda's Kitchen's background in catering for London's diverse corporate workforce has developed exactly this knowledge — the awareness that dietary requirements extend beyond medical allergies to encompass cultural, religious, and seasonal variations that deserve the same careful management. See our guides to Ramadan catering and Eid catering for how we approach cultural dietary occasions.
