Summary

According to the UK Association of Convenience Stores, over 50,000 convenience stores were operating nationwide in 2025, of which 71% were independently owned. Despite their large numbers and relatively high energy use, this sector remains overlooked in energy and decarbonisation studies. This study develops a bottom-up modelling framework to estimate energy use and greenhouse gas emissions in UK independent convenience stores. Detailed EnergyPlus models were developed for two store archetypes, together representing approximately 31% of independent convenience stores nationally. The combined annual energy consumption of these stores was estimated at 770.7 GWh. Associated greenhouse gas emissions amounted to 169.9 ktCO₂e, comprising 150.7 ktCO₂e from Scope 2 electricity use and 19.24 ktCO₂e from Scope 1 refrigerant-related emissions. These results establish a quantified baseline for assessing refrigeration-related emissions in small food retail and support evaluation of decarbonisation strategies.
