Greggs

Greggs, one of the UK’s best-known bakery chains, required a reliable and automated food safety monitoring solution to support compliance with British Retail Consortium (BRC) standards. Manual temperature checks were labour-intensive, prone to human error, and time-consuming. By implementing Invisible Systems’ wireless monitoring technology and the Live by Invisible Systems portal, Greggs not only validated continuous monitoring for its annual BRC audit but also unlocked long-term operational and environmental benefits.

Greggs: Automating Food Safety and Energy Efficiency with Smart Monitoring

Challenge

The company identified the need to automate temperature monitoring across refrigeration and freezer units at its food manufacturing sites. Manual monitoring was inefficient and susceptible to error, increasing both operational risk and administrative workload. Greggs’ leadership team sought a solution that would automate condition monitoring, reporting, and recordkeeping to meet strict BRC compliance requirements while improving energy efficiency and sustainability performance.

Solution

With support from Invisible Systems, Greggs implemented a comprehensive I-System solution featuring wireless temperature transmitters, RF gateways, wireless pulse transmitters, and wireless electricity meters. This integrated setup allowed continuous, real-time monitoring of key environmental and energy parameters across all relevant facilities. The system provided automated reporting, proactive alerts, and a centralised portal for compliance management.

Results and Impact

Automated monitoring: Continuous condition and temperature monitoring across multiple sites, ensuring complete BRC compliance.
‍
Automated reporting: Seamless production of records for audits and compliance validation.
‍
Proactive maintenance: Real-time data enabled an active asset maintenance programme, reducing downtime and repair costs.
‍
Energy and cost savings: Ongoing 5% reduction in energy consumption across all utilities.
‍
Sustainability gains: Lower carbon emissions through improved energy efficiency and optimised asset performance.

Future Direction

Greggs continues to expand the use of smart monitoring technologies across its operations to further enhance sustainability, efficiency, and food safety. The company aims to build on the success of its initial implementation by integrating additional sensors and analytics capabilities to drive continuous improvement.

Conclusion

Through its collaboration with Invisible Systems, Greggs has achieved full automation of food safety monitoring, improved compliance, and reduced operational costs. The intelligent monitoring solution provides accurate data, continuous assurance, and measurable environmental benefits, supporting Greggs’ commitment to quality, efficiency, and sustainability.
