The UK’s supermarket refrigeration sector is entering another major investment cycle. Rising energy costs, tighter environmental regulations and the continuing phase-down of hydrofluorocarbon (HFC) refrigerants are forcing retailers to modernise cooling systems faster than originally planned. Britain’s grocery industry has also become one of Europe’s leading adopters of natural refrigerants, particularly carbon dioxide (CO₂) and propane-based technologies.
For equipment manufacturers, engineering specialists and service providers, the transition is creating a wave of opportunities. Refrigeration is no longer simply an operational necessity for supermarkets. It has become a strategic investment linked to sustainability targets, energy efficiency and food quality.

1. Carter Retail Equipment
Founded: 1945
Headquarters: Birmingham, England
FY Revenue: Private
Carter Retail Equipment is one of the UK’s best-known supermarket refrigeration and shopfitting specialists. The company supplies refrigeration equipment, display systems and integrated store solutions to many of Britain’s largest retailers.
Its long history with major supermarket chains has made it a key supplier for store refurbishments and new store developments. Carter’s ability to combine refrigeration, shelving and fit-out services under one roof gives it a strong competitive position.
2. Epta UK
Headquarters: Bradford, England
FY Revenue: Private
Epta UK, which includes the long-established George Barker refrigeration business, is one of the country’s largest suppliers of refrigerated display cabinets and integrated cooling systems.
The company has built a significant presence across the supermarket sector by combining local manufacturing expertise with the scale of the wider Epta Group. Energy-efficient refrigeration and natural refrigerant technologies remain key areas of investment.
3. Space Engineering Services
Founded: 1988
Headquarters: Bristol, England
FY Revenue: Private
Space Engineering Services occupies a crucial role in the UK market because it designs, installs and maintains refrigeration systems rather than manufacturing display equipment.
The company works extensively with supermarkets, food manufacturers and distribution centres. Its engineering capabilities and long-standing retail relationships have made it one of the UK’s leading refrigeration contractors.
4. Clade Engineering Systems
Founded: 1985
Headquarters: Bristol, England
FY Revenue: Private
Clade has become one of Britain’s leading natural refrigerant specialists.
Since its acquisition by France’s Groupe Atlantic in 2023, the company has gained greater resources to scale natural refrigerant heat pumps and transcritical CO₂ technologies.
Clade’s systems allow supermarkets to recover heat generated by refrigeration systems and reuse it to heat stores and provide hot water, reducing reliance on gas boilers.
5. AHT Cooling Systems UK
Headquarters: Orpington, Greater London
FY Revenue: Private
AHT is one of the dominant players in self-contained refrigeration and freezer equipment.
Its plug-in systems are widely used by convenience stores and discount retailers because they are relatively simple to install and require less maintenance than traditional remote systems.
The company has also benefited from growing demand for propane-based refrigeration technologies.
6. Hussmann UK
Founded: 1906
Headquarters: Kilmarnock, Scotland
FY Revenue: Private
Hussmann remains one of the largest global suppliers of supermarket refrigeration equipment operating in Britain.
Its display cases and integrated systems are widely used by supermarket chains seeking to reduce energy consumption and adopt lower-emission technologies.
The company has invested heavily in CO₂ refrigeration and continues to play an important role in store modernisation programmes.
7. Arneg UK
Headquarters: St Ives, Cambridgeshire
FY Revenue: Private
Arneg is one of Europe’s largest manufacturers of refrigerated display equipment and has built a strong position within the British grocery market.
The company supplies refrigerated cabinets and integrated systems to retailers seeking environmentally friendly refrigeration technologies and improved energy performance.
8. SCM Frigo UK
Headquarters: Leeds, West Yorkshire
FY Revenue: Private
SCM Frigo has gained a growing presence in Britain through its expertise in CO₂ refrigeration technologies.
The company designs and supplies transcritical systems and refrigeration packs that are increasingly being adopted by retailers upgrading older HFC-based installations.
9. Carrier Commercial Refrigeration UK (A Haier Company)
Headquarters: United Kingdom
FY Revenue: Private
Carrier Commercial Refrigeration underwent a major change in late 2024 when Haier Smart Home completed its $775 million acquisition of the entire Carrier Commercial Refrigeration business.
The transaction included manufacturing operations, service networks and legacy brands.
Although the business continues to operate under the Carrier name, it now benefits from Haier’s scale and technology capabilities. Its extensive installed base and nationwide service network remain highly important to the UK supermarket sector.
10. Star Refrigeration
Founded: 1970
Headquarters: Glasgow, Scotland
FY Revenue: Private
Star Refrigeration is best known for industrial cooling and large-scale refrigeration systems.
Its importance to the grocery industry comes through temperature-controlled distribution centres and food logistics infrastructure that support Britain’s major supermarket chains.
Large chilled and frozen distribution facilities have become increasingly important as retailers expand online grocery operations and invest in supply-chain resilience.
Industry Outlook
The UK remains one of Europe’s most advanced markets for natural refrigerants.
The continuing phase-down of HFC refrigerants under UK F-Gas regulations is accelerating investment in lower-emission technologies. Traditional supermarket refrigerants such as R404A have a Global Warming Potential (GWP) of nearly 3,900.
By comparison:
- CO₂ (R744) has a GWP of 1.
- Propane (R290) has a GWP of 3.
These differences are increasingly influencing investment decisions inside major supermarket groups.
Heat recovery is also becoming standard practice. Many retailers now use waste heat generated by refrigeration systems to warm stores and provide hot water, helping to reduce both emissions and energy costs.
What Happens Next?
The next few years are expected to bring another wave of refrigeration upgrades across the UK grocery industry as retailers prepare for tighter refrigerant rules and higher energy costs.
Large supermarket chains are likely to accelerate investment in CO₂ systems, while convenience and discount retailers continue to adopt self-contained propane technologies.
The transition is creating opportunities across the UK retail technology sector. For the UK grocery store industry, refrigeration has become a critical component of carbon reduction and store efficiency strategies. Across the wider UK FMCG sector, investment in modern cold-chain infrastructure is helping improve food quality, reduce waste and strengthen supply-chain resilience.
