Allergy Awareness Week 2026 runs from 20-26 April, with the theme "I Wish I Knew… Diagnosis Matters." This year's theme focuses on the diagnostic journey — the delays, misdiagnoses, and life-changing moments that characterise allergy diagnosis in the UK — and what better awareness and faster diagnosis would mean for the estimated 21 million UK adults living with at least one allergy. For London employers and HR professionals, Allergy Awareness Week is a timely prompt to review how food allergens are managed in the workplace — a legal, safety, and inclusion responsibility that many organisations still approach inadequately.
How many people have food allergies in the UK?
Food allergy affects approximately 1-2% of UK adults and up to 8% of children — meaning that in any London office of 100 people, one or two colleagues are likely to have a diagnosed food allergy, and significantly more will have food intolerances or sensitivities that affect their dietary choices. Peanut allergy alone affects approximately 640,000 UK adults. Tree nut allergies affect a further significant proportion. The UK has one of the highest food allergy prevalence rates in the world, driven by a combination of genetic predisposition, hygiene hypothesis factors, and dietary patterns. The Allergy UK charity estimates that the number of people living with allergies in the UK has doubled in the past 20 years and continues to rise. The Anaphylaxis UK charity reports that hospital admissions for anaphylaxis have increased by 72% in the past decade.
The workplace food allergen risk: what the law requires
UK food law — including the Food Information Regulations 2014 and Natasha's Law (Food Information Amendment Regulations 2021) — places specific obligations on food businesses, including corporate caterers delivering to workplaces. The 14 mandatory allergens that must be declared in food labelling are: cereals containing gluten, crustaceans, eggs, fish, peanuts, soya, milk, nuts (almonds, hazelnuts, walnuts, cashews, pecan nuts, Brazil nuts, pistachio nuts, macadamia nuts), celery, mustard, sesame seeds, sulphur dioxide and sulphites, lupin, and molluscs. Under Natasha's Law, any food prepacked for direct sale — including individually packaged lunches delivered to offices — must carry full ingredient labelling clearly identifying all 14 allergens. The Food Standards Agency allergen guidance for food businesses provides the definitive legal reference. Organisations commissioning catering have a duty of care to ensure that the food provided meets these standards — selecting a caterer who cannot demonstrate Natasha's Law compliance exposes the commissioning organisation to legal risk as well as safety risk.
What does "Diagnosis Matters" mean for workplace food provision?
This year's Allergy Awareness Week theme reflects a painful reality: the average time to diagnosis for food allergy in the UK is significantly delayed — sometimes years — during which individuals manage unknown risks, suffer reactions, and navigate a food environment not designed with their safety in mind. When a colleague has not yet received a diagnosis for their allergy or intolerance, they are making food choices in the workplace with incomplete information about their own risk. This makes the food safety practices and labelling standards of the caterers feeding your office not just a matter of compliance, but a genuine safety net for people at various stages of their allergy journey. The Allergy UK Allergy Awareness Week 2026 resources provide educational materials for employers and HR teams wanting to improve workplace allergy management.
The 5 most common allergen incidents in London workplaces
Based on reported food allergy incidents in food service settings, the five most common allergen-related workplace incidents are: 1. Unlabelled or mislabelled food at catered events — where shared platters or buffet food lacks allergen information, leaving individuals to guess or avoid all shared food. 2. Cross-contamination from shared serving utensils — a single spoon used across multiple dishes transferring allergen traces to supposedly allergen-free options. 3. Caterer substitutions without allergen reassessment — a last-minute ingredient change not communicated to allergy-aware customers. 4. "May contain" disclaimers treated as allergen-free — individuals unaware that precautionary "may contain" labelling indicates a genuine cross-contamination risk. 5. Office birthday cakes and informal food sharing — unpackaged, unlabelled food brought into the workplace by well-meaning colleagues, with no allergen information available. All five of these incidents can be eliminated through proper catering selection and workplace food policies. The Food Standards Agency "Is it in your food?" campaign provides public awareness resources relevant to these scenarios.
What inclusive allergen-safe workplace catering looks like in practice
For London offices commissioning team lunches, the standard for inclusive allergen-safe catering is specific: every item should carry full ingredient and allergen labelling in compliance with Natasha's Law; the caterer should be able to demonstrate their allergen management procedures; food should not be subject to unannounced ingredient changes; and where possible, a dedicated allergen-free facility — rather than a shared kitchen — provides the highest safety assurance. Vanda's Kitchen provides all of this from our EC4 kitchen: full Natasha's Law compliant labelling on every item, an online allergen matrix covering all 14 mandatory allergens across every product, a 100% nut-free dedicated kitchen (eliminating the most common and most dangerous single allergen in UK workplaces), and independently verified halal certification. Our food is also suitable across a wide range of other dietary requirements — gluten-free options, dairy-free preparations, egg-free choices — all clearly labelled.

How to mark Allergy Awareness Week in your London office
Allergy Awareness Week is an opportunity to raise employee awareness, review workplace food policies, and signal organisational commitment to food safety and inclusion. Practical actions for London HR and facilities teams during the week of 20-26 April 2026: host an allergen awareness session during a team lunch — invite an allergy-aware caterer to present alongside the food; review your current catering provider's Natasha's Law compliance and ask for their allergen matrix; audit informal food sharing practices in the office and establish a clear policy; share Allergy UK's 2026 awareness resources with employees; update your HR onboarding process to include a dietary requirements and allergy declaration step; and consider whether your current corporate caterer can genuinely serve every employee safely. The Natasha Allergy Research Foundation provides employer resources relevant to workplace allergy management.
People also ask about food allergies at work
Do employers have a legal duty to accommodate food allergies? Under the Equality Act 2010, severe food allergies may qualify as a disability requiring reasonable adjustments. The Food Standards Agency and Allergy UK both publish employer guidance on workplace allergen responsibilities. While there is no specific legal requirement to provide allergen-safe catering, the duty of care, Health and Safety at Work Act obligations, and Equality Act implications mean that employers providing workplace food have a responsibility to ensure it can be consumed safely by all employees. What is the difference between a food allergy and a food intolerance? A food allergy involves an immune system response to a food protein — reactions can be immediate and severe (anaphylaxis). A food intolerance involves a non-immune response (typically digestive) that is usually less immediately dangerous but can significantly affect quality of life. Allergy UK's diagnostic resources cover both conditions. When is Allergy Awareness Week 2026? Allergy Awareness Week 2026 runs from 20-26 April 2026. The theme is "I Wish I Knew… Diagnosis Matters."

Food allergy statistics in UK workplaces
According to Allergy UK and NHS England, peanut allergy affects an estimated 640,000 UK adults, NHS hospital admissions for anaphylaxis have increased 72 percent in the past decade, and non-coeliac gluten sensitivity affects an estimated 6-10 percent of the population. The cumulative picture: in any London office of 100 people, potentially 15-20 individuals have dietary requirements driven by allergy, intolerance, or medical condition. A corporate caterer who cannot address this range is not providing genuinely inclusive corporate catering.
Building an allergy-aware workplace food policy
An effective workplace allergen policy addresses four contexts: commissioned catering, informal food sharing, client-provided food, and vending and on-site retail. For commissioned catering — the most controllable category — selecting caterers providing full Natasha Law compliant labelling and operating from allergen-managed facilities eliminates most risk. The Food Standards Agency allergen guidance includes model allergen policies adaptable for workplace use. The Natasha Allergy Research Foundation provides employer-specific allergen awareness resources. For HR teams marking Allergy Awareness Week, updating the catering policy and sharing Allergy UK 2026 resources with employees are the highest-impact immediate actions.
Supporting colleagues with food allergies
Beyond physical catering provision, managers have a role in creating a culture where employees with food allergies feel safe rather than anxious and isolated. Include a dietary requirements declaration in the onboarding process and update it annually. Ensure catered events include food every employee can eat without separate special diet options that highlight difference. Brief employees managing catering orders on the importance of allergen accuracy. Review whether your current caterer can genuinely serve every employee safely — if they cannot, Allergy Awareness Week is the right moment to make a change. Contact us to discuss corporate catering that includes every colleague by design.

Commissioning allergen-safe catering for your London office
Allergy Awareness Week is an ideal moment to review your workplace catering provision against the standards described in this guide. The questions to ask: does your current caterer provide full Natasha Law compliant labelling on every item? Can they provide an allergen matrix? Do they operate from an allergen-managed facility? Can they genuinely serve every employee — including those with nut allergies, halal requirements, gluten intolerance, and dairy avoidance — from a single order? If not, Vanda Kitchen provides all of these from our certified halal, 100 percent nut-free, EC4 kitchen. Contact us to discuss switching your workplace catering. We offer a free first order for new corporate accounts established during Allergy Awareness Week 2026.
