Innocent Drinks Tackles Food Waste and Liverpool’s Retrofit Success
Two recent programmes highlight how UK organisations are turning sustainability commitments into measurable results. Innocent Drinks has been working to reduce food waste across its supply chain. Meanwhile, Liverpool City Region has completed a major housing retrofit scheme covering hundreds of homes. Both efforts show that environmental progress depends on practical systems change rather than aspirational targets.
These examples matter because they address avoidable costs and emissions at scale. For businesses watching from the sidelines, they illustrate what serious environmental work actually looks like. It involves measurement, investment, and collaboration across organisational boundaries.
The programmes also demonstrate different pathways to the same destination. One focuses on preventing waste in a perishable supply chain. The other tackles energy efficiency in ageing housing stock. However, both require accurate data, willing partners, and realistic timelines.
How Liverpool delivered retrofit across 836 homes
Liverpool City Region has been running housing retrofit programmes designed to cut carbon emissions while improving living conditions. An evaluation by the National Institute for Health and Care Research examined work covering more than 6,000 homes between 2021 and early 2025. Consequently, the research focused on whether access was equitable and how upgrades affected household finances and health.
One completed scheme provides concrete detail on what retrofit looks like at scale. Torus, a housing provider, upgraded 836 homes across Liverpool, Warrington and St Helens between 2023 and March 2026. The total investment reached £41 million. Specifically, £9 million came through the Liverpool City Region Combined Authority's Registered Provider Consortium. Torus itself contributed £32 million.
The work included wall, loft and roof insulation. Contractors also installed replacement windows and doors, improved ventilation systems, and fitted air source heat pumps. Solar panels were added to some properties. Additionally, several homes received new roofs and other building fabric improvements.
All upgraded homes reached at least Energy Performance Certificate rating C. Previously, many were rated D or below. Torus reported that residents now experience warmer winters and cooler summers. Importantly, the amount of energy required for heating has fallen.
The programme covered various property types. These included houses, bungalows and apartments. Within Liverpool itself, 72 city centre apartments were upgraded. Another 130 homes in Walton also benefited. Properties elsewhere in the wider region made up the remainder.
Torus has already secured funding for the next phase. The Warm Homes Social Housing Fund will support improvements to more than 1,000 additional properties over three years. Therefore, the programme continues beyond its initial scope.
Why food waste reduction requires supply chain coordination
Innocent Drinks has been addressing food waste across its fruit-based beverage production. The initiative forms part of wider efforts to reduce losses associated with perishable agricultural products. Waste can occur at multiple points. Farmers may discard imperfect fruit. Processing facilities generate by-products. Retailers remove stock approaching expiry dates. Households throw away unused items.
The central challenge is preventing waste rather than managing it after the fact. This requires better forecasting so production matches demand more closely. It also depends on supplier coordination to find uses for surplus or imperfect produce. Processing efficiency improvements can reduce material losses during manufacturing.
Food waste carries significant environmental costs. Wasted food represents squandered land, water, energy, labour and transport. When organic material reaches landfill, it generates methane, a potent greenhouse gas. Consequently, preventing waste supports both resource efficiency and emissions reduction.
The most credible programmes combine several approaches. Prevention comes first in the waste hierarchy. Redistribution to charities or food banks offers a second option. Some materials can become animal feed. Composting or anaerobic digestion provide further alternatives. However, none match the environmental benefit of preventing surplus in the first place.
This initiative reflects broader expectations around corporate sustainability. Businesses now face pressure to demonstrate measurable outcomes in their operations and supply chains. Long-term pledges matter less than verified results. Therefore, transparent reporting has become essential.
Retrofit investment delivers multiple benefits beyond carbon reduction
Housing retrofit addresses several problems simultaneously. Energy efficiency improvements cut carbon emissions. They also reduce household bills, improve thermal comfort, and can support better health outcomes. Consequently, retrofit sits at the intersection of climate policy, housing standards and public health.
Much of the UK's housing stock predates modern energy efficiency standards. Older homes often have solid walls, single-glazed windows, minimal loft insulation and inefficient heating systems. Consequently, they lose heat rapidly and cost more to warm. Residents face higher energy bills, and many struggle with fuel poverty.
The Liverpool evaluation specifically examines potential health benefits alongside financial impacts. Cold, damp homes contribute to respiratory conditions, cardiovascular problems and mental health issues. Better insulation and heating can reduce these risks. However, the evaluation also notes that unequal access to retrofit could reinforce existing health inequalities.
Energy Performance Certificate improvements provide a useful measure. Nevertheless, they do not automatically prove how much energy households save in practice. Actual consumption depends on occupant behaviour, heating patterns and comfort expectations. Therefore, monitoring real energy use matters as much as theoretical performance.
The Torus programme demonstrates the scale of investment required. £41 million covered 836 homes, averaging roughly £49,000 per property. This figure exceeds what most homeowners could afford independently. Consequently, public funding and housing provider investment become essential to achieving scale.
The Liverpool model combines several funding sources. Government grants provide part of the capital. Local authority coordination ensures strategic delivery. Housing providers contribute their own resources. Specialist contractors bring technical expertise. This partnership approach distributes costs while maintaining quality standards.
For SMEs in the construction sector, retrofit programmes create sustained demand. Insulation installers, heating engineers, window fitters and solar panel specialists all find work through these schemes. Additionally, supply chain businesses benefit from increased demand for materials and components.
What UK businesses can learn from these programmes
- Prevention delivers greater environmental benefits than disposal or recycling, whether addressing food waste or energy losses through poor insulation.
- Credible sustainability work requires measurement and transparent reporting of actual outcomes, not just aspirational targets or theoretical performance figures.
- Partnership models that combine public funding, private investment and specialist delivery capacity enable scale that single organisations cannot achieve alone.
- Environmental improvements often produce social benefits including reduced household costs, better health outcomes and improved living conditions for vulnerable groups.
- Supply chain collaboration matters more than individual company action when addressing systemic waste or inefficiency embedded across multiple stages of production and distribution.
- Long-term programmes with secure funding deliver better results than short-term initiatives that end before achieving meaningful scale or proving sustained impact.
Where business opportunities and compliance pressures intersect
These programmes arrive as regulatory expectations around sustainability continue to tighten. Large companies already face mandatory climate reporting under the Streamlined Energy and Carbon Reporting framework. Many SMEs encounter sustainability requirements through public procurement rules. Procurement Policy Note 06/21 requires suppliers bidding for central government contracts above £5 million to publish carbon reduction plans.
Consequently, businesses need systems to measure, reduce and report environmental impacts. Food manufacturers face questions about supply chain waste. Construction firms encounter specifications for energy-efficient materials and methods. Facilities management companies must demonstrate building performance improvements.
The Liverpool retrofit programme shows how public sector spending drives demand for specific capabilities. Housing providers need contractors who understand fabric-first approaches, heat pump installation and renewable energy integration. Therefore, businesses with these skills gain competitive advantages in bidding processes.
Similarly, food and beverage companies increasingly face customer and investor questions about waste. Retailers want suppliers who can demonstrate waste prevention across operations. Corporate customers seek partners with credible environmental management systems. As a result, waste reduction becomes commercially relevant beyond its environmental benefits.
For SMEs supplying larger organisations, these trends create both pressure and opportunity. Supply chain sustainability requirements can feel burdensome. However, they also establish clearer expectations and create markets for environmental improvement services. Businesses that build genuine capability benefit as requirements spread.
Our net zero programme for carbon reporting compliance helps businesses develop the measurement and management systems required for public sector tenders and supply chain expectations. The work involves identifying emission sources, establishing baselines, setting reduction targets and implementing practical improvements.
Training also matters. Understanding retrofit principles, waste hierarchy applications or Scope 3 emissions accounting requires specific knowledge. The SBS Academy training on sustainability topics provides accessible learning for teams without prior environmental expertise.
Why accurate measurement underpins credible environmental claims
Both programmes demonstrate the importance of quantified outcomes. The Torus scheme reports specific numbers of homes upgraded, investment amounts, and Energy Performance Certificate ratings achieved. The food waste initiative depends on tracking quantities prevented, redistributed or diverted from landfill.
Without measurement, sustainability claims remain unverifiable. Businesses face growing scrutiny over greenwashing. Regulators are developing stricter rules around environmental marketing claims. Therefore, the ability to demonstrate actual results becomes essential.
For food businesses, this means tracking waste volumes at different supply chain stages. It requires knowing how much material enters processing, what proportion becomes finished product, and where losses occur. Some waste may be unavoidable due to safety standards or product specifications. However, identifying avoidable waste creates opportunities for improvement.
Retrofit programmes require similar rigour. EPC ratings provide standardised comparison between properties. Nevertheless, actual energy consumption data shows real-world performance. Monitoring household bills demonstrates financial benefits. Resident surveys capture comfort and satisfaction improvements. Collectively, these measures build evidence of genuine impact.
Our ESG compliance and carbon reporting services help businesses establish measurement systems that withstand scrutiny. The work includes identifying appropriate metrics, setting up data collection processes, and ensuring reporting aligns with recognised standards.
Accessing government resources on retrofit and waste reduction
The UK government provides detailed guidance on both housing retrofit and waste reduction strategies. The Department for Energy Security and Net Zero oversees energy efficiency policy and funding programmes. Their website includes information on available grants, technical standards and upcoming regulatory changes.
The Warm Homes Social Housing Fund provides capital grants for social housing providers to improve energy performance. Wave 2 funding runs from 2024 to 2027. Consequently, housing associations and local authorities can access support for retrofit projects similar to the Liverpool programme.
For businesses addressing food waste, the Resources and Waste Strategy for England sets out the policy framework. It includes targets for waste reduction, separate food waste collection requirements, and extended producer responsibility schemes. Understanding these regulations helps businesses anticipate compliance obligations.
The Waste and Resources Action Programme offers practical guidance on waste prevention across various sectors. Their resources cover measurement methodologies, case studies and sector-specific recommendations. Therefore, businesses can find relevant examples applicable to their operations.
Finally, Energy Performance Certificate registers allow property owners to check current ratings and understand improvement options. The registers also provide data on typical costs and potential savings from different upgrade measures.
