Safe food storage isn’t simply about keeping products fresh; it’s about meeting legal obligations, maintaining the trust of your customers, and of course, protecting public health. So, for businesses in the food supply chain, from supermarkets and restaurants to cold storage facility designers, compliance with food safety standards is critical.

Failing to meet these standards can lead to foodborne illness outbreaks, product recalls, fines, and reputational damage that can stick around forever. On the other hand, having a recognised certification under your belt demonstrates professionalism, opens doors to major retail partnerships, and ensures you’re always audit-ready.

In this guide, we’re exploring the key food safety certifications and regulations in the UK, why they exist, their impact on your cold storage, and how to make them work for your business.

Understanding Food Hygiene Certification

Food hygiene certification is an important (and in many cases, mandated) indicator that your team understands how to handle food safely. While there’s no legal requirement for specific certificates, UK law does require that anyone handling food receive appropriate training and supervision. For most businesses, certification is the simplest and most reliable way to demonstrate compliance.

What Does Food Hygiene Cover?

Food hygiene refers to the processes and conditions that keep food safe throughout its journey - from storage and handling to preparation, cooking, and serving. Poor hygiene can lead to contamination by bacteria, chemicals, or foreign objects, causing serious illnesses such as food poisoning.

Key Food Safety Certifications & Standards

Whether you work with raw meats, frozen foods, food waste or any other food-related product or service, here are the most important certifications and standards for food health and safety in the UK:

HACCP (Hazard Analysis and Critical Control Points)

The foundation of modern food safety is laid by HACCP - a globally recognised, systematic approach to identifying, evaluating, and controlling hazards across the entire food supply chain. 

In the UK, HACCP isn’t just best practice - it’s legally required. Under Regulation (EC) No 852/2004, all food businesses must have a HACCP-based food safety management system in place.

That said, HACCP is not a singular, universal certification but rather a system of training and accreditation to demonstrate competence in implementing the above, and individuals can obtain certifications like Level 2, 3, or 4 HACCP to prove their knowledge and ability to manage food safety within their workplaces.

The Role of HACCP in Cold Storage

Cold storage operations rely heavily on HACCP principles to keep food safe. Here’s how:

  • Temperature-critical control points - Monitoring temperatures during delivery, storage, and dispatch to prevent bacterial growth.

  • Preventing cross-contamination - Designing workflows, storage layouts, and cleaning regimes that protect against raw-to-ready product contamination.

  • Equipment reliability - Implementing checks to ensure refrigeration units are functioning properly and alarms are in place for failures.

  • Traceability and corrective actions - Documenting and addressing any deviations quickly to protect consumers and maintain compliance.

Without HACCP, there’s no reliable way to prove that a food business is managing risks effectively. For cold storage facilities, it’s the first and most essential step toward maintaining product integrity and safeguarding public health.

ISO 22000 - A Global Food Safety Management Standard

Beyond the basics of food hygiene training and certification, many food businesses choose to adopt ISO 22000, an internationally recognised Food Safety Management System (FSMS). While food hygiene certificates show that individuals understand safe practices, ISO 22000 takes this a step further by using those practices to create a comprehensive, organisation-wide framework.

Unlike HACCP, which focuses on risks within a single site or stage of production, ISO 22000 looks at food safety across the entire supply chain - from farm and factory, through distribution, right to the end consumer.

The Role of ISO 22000 in Food Storage

Safe storage is one of the most critical aspects of food safety, and ISO 22000 provides a framework to manage it effectively. The standard requires businesses to:

  • Identify storage hazards - From harmful bacteria growing in chilled goods to cross-contamination during bulk food storage.

  • Control temperature and humidity - Ensuring that chilled, frozen, and ambient storage areas are maintained at safe levels.

  • Maintain traceability - Making sure stock can be tracked back through the supply chain in the event of a recall.

  • Document and review procedures - Including monitoring fridge/freezer performance, cleaning schedules, and pest control records.

  • Train staff consistently - Ensuring everyone handling stored food understands the risks and the controls in place through food safety training.

By adopting ISO 22000, businesses can be confident that their storage practices are systematic, measurable, and globally recognised. Combined with staff food hygiene certification, it creates a strong foundation for protecting consumers and maintaining high safety standards.

BRCGS Global Standard for Food Safety

For UK-based retail food businesses, the BRCGS (Brand Reputation Compliance Global Standards) Food Safety Standard is often seen as the benchmark for excellence. Developed by the British Retail Consortium, this certification has become a requirement for suppliers to major UK supermarkets and many leading foodservice providers.

As the first standard to be GFSI benchmarked, BRCGS is a rigorous certification that evaluates every aspect of a food operation, from hygiene and site layout to supplier management and traceability. It is widely recognised across the UK and beyond (in 130 countries), making it an excellent credential for businesses looking to secure contracts with large retailers or distributors.

The Role of BRCGS in Cold Storage

Cold storage is a critical focus area within BRCGS. To achieve and maintain certification, businesses must demonstrate: 

  • Strict temperature management - Monitoring, recording, and maintaining correct temperatures for chilled and frozen goods.

  • Hygienic layout and workflow - Designing storage areas to prevent cross-contamination between raw and ready-to-eat products.

  • Pest control measures - Proactively managing risks in environments where temperature fluctuations could attract pests.

  • Robust cleaning and maintenance schedules - Ensuring storage facilities, equipment, and vehicles remain clean and operational.

  • Comprehensive documentation - Keeping detailed records of inspections, audits, and corrective actions.

Achieving BRCGS certification shows buyers and regulators that your cold storage operations meet the highest UK retail standards. It not only protects consumers but can also open the door to lucrative supply contracts with some of the biggest names in the industry.

Food Hygiene Certificates - Training for Staff

Food hygiene certificates demonstrate that individuals have been trained in safe food handling, including temperature control, cross-contamination prevention, and record-keeping.

How is this relevant to cold storage, you ask? Well, level 2 Food Hygiene is generally required for food handlers, and level 3 is recommended for managers and supervisors overseeing storage operations.  

Tip: The Food Standards Agency has a few free online courses that are worth checking out.

What Type of Businesses Need Safe Food Storage Certification

Environmental Health Officers (EHOs) regularly inspect food businesses to ensure they meet hygiene standards. During these inspections, EHOs will assess both the practices of your staff and the condition of your premises. Inspections commonly occur at:

  • Restaurants, cafés, and bars

  • Catering companies and food vans

  • Supermarkets and convenience stores

  • Care homes and hospitals

  • Schools, colleges, and nurseries

  • Hotels, community centres, and leisure facilities
