New research has revealed that 'dark kitchens' now account for around 15 per cent of all food retailers on major delivery platforms in England.

The study highlights widespread confusion among consumers and regulators and the need for food safety transparency. Food hygiene training experts High Speed Training are explaining exactly what the term ‘dark kitchen’ means and how it really affects food businesses and the public.

Dr. Richard Anderson, Head of Learning & Development at High Speed Training said: “The rapid rise of dark kitchens, often operating from industrial units or shipping containers, has created a significant gap in transparency. Consumers are often unaware of where their food is being prepared, and these setups can present unique challenges for food hygiene and allergen control that are different from a traditional restaurant.”

A 'dark kitchen', also known as a ghost or cloud kitchen, is a professional kitchen facility set up purely for delivery-only meals. Orders are placed online, and there is no physical storefront or dining area for the public.

The Sheffield Hallam study, which created the first widely agreed-upon UK definition, describes them as “technology-enabled commercial kitchen(s) operating primarily for delivery, to fulfil remote, on-demand, consumer online orders of food for immediate consumption.”

While dark kitchens are subject to Food Standards Agency (FSA) inspections, there are fears that standards may not be as high due to the nature of their operation. High Speed Training identifies several key risks:

In shared kitchens where multiple 'brands' or businesses operate from the same space, the risk of allergen cross-contamination is high if equipment and processes are not robustly managed.

This business model can sometimes avoid the complex planning requirements that traditional takeaways face, making oversight more difficult for local authorities.

High Speed Training notes that lone working in cramped or windowless conditions can lead to increased staff stress, which can negatively impact diligence in following food safety procedures.

Dr Anderson continues: “For this 15 per cent of the market and beyond, balancing cost with compliance is critical. A single food safety or allergen incident can be disastrous for a brand that exists only online. Investing in comprehensive staff training on food hygiene and allergen management isn't just a legal requirement; it's the most important step operators can take to protect their customers and their business.”
