As the UK accelerates efforts to meet its legally binding net-zero carbon emissions target by 2050, the role of housing—particularly social housing—has come into sharp focus. With residential properties contributing approximately 14% of UK greenhouse gas emissions, the drive to reduce carbon output has become a national priority.
One of the most impactful strategies in this journey is the implementation of zero carbon housing retrofit programmes. Leading this charge is Cardo Group, a specialist provider of property services for the social housing sector, committed to transforming the way homes are maintained, upgraded, and future-proofed.
This article explores how Cardo Group is tackling the challenge of decarbonisation through strategic, scalable, and community-driven retrofit services designed to deliver long-term value for tenants, housing associations, and the environment.
The UK government has set ambitious targets to improve energy efficiency across the nation’s housing stock. In particular, there’s a strong push to ensure that all rented homes achieve a minimum of EPC Band C by 2030. For social housing providers, this means assessing and upgrading thousands of properties—many of which were built decades ago and fall far short of current performance standards.
In response, funding mechanisms like the Social Housing Decarbonisation Fund (SHDF) have been introduced to support registered providers in delivering comprehensive energy efficiency upgrades. But meeting these targets requires more than funding—it demands expertise, strategic planning, and operational excellence.
Cardo Group is uniquely positioned to support the transition to net-zero in the social housing sector. With a multidisciplinary team and an integrated service model, the company delivers retrofit and energy efficiency programmes that align with both national policy and local priorities.
Their approach is underpinned by:
Cardo Group works closely with local authorities, housing associations, and public sector clients to deliver solutions that are tailored, compliant, and future-focused.
A zero carbon housing retrofit involves upgrading existing homes to drastically reduce or eliminate carbon emissions. Unlike new builds, retrofitting focuses on improving the fabric and systems of existing dwellings. This includes:
The goal is to create homes that consume less energy, emit fewer emissions, and maintain high living standards for tenants—all while supporting the UK’s broader environmental goals.
For Cardo Group, achieving net-zero is not about piecemeal upgrades—it’s about delivering integrated, evidence-based energy efficiency upgrades across entire housing portfolios. Their service offering includes:
Each project begins with a comprehensive evaluation of the property’s current performance. Using EPC data, thermal imaging, and ventilation analysis, Cardo Group develops bespoke plans that address both fabric and system inefficiencies.
Retrofit works are coordinated to minimise disruption. Cardo Group works directly with residents to explain the process, gather feedback, and ensure that upgrades not only improve performance but also enhance comfort and usability.
All works are delivered by trained professionals who specialise in retrofit compliance, working in line with PAS 2030/2035 standards. This includes coordination with domestic energy assessors and retrofit coordinators.
Upon completion, Cardo Group carries out validation checks, post-installation EPC ratings, and tenant feedback surveys—ensuring that promised energy savings and comfort levels are achieved.
Cardo Group’s impact extends beyond individual homes. By forming long-term partnerships with councils and housing associations, they are helping shape policy, funding applications, and strategic decarbonisation pathways.
Their expertise allows clients to:
This partnership-based model ensures that housing providers not only meet their legal obligations but also unlock the broader social and economic benefits of retrofit—such as lower fuel bills, improved tenant wellbeing, and sustainable local employment.
Reaching EPC Band C is often the first milestone on the path to net-zero. Cardo Group supports clients in mapping out achievable pathways, prioritising works that deliver the highest uplift in EPC performance. Key interventions include:
Each measure is selected based on a careful cost-benefit analysis that factors in carbon reduction potential, tenant impact, and long-term maintenance.
For Cardo Group, sustainability is not just about carbon—it’s also about community. Their retrofit programmes are designed to deliver wide-reaching social value, including:
This community-first approach ensures that retrofit is inclusive, accessible, and aligned with the lived experience of tenants—particularly in social housing settings where affordability and comfort are critical.
In several UK boroughs, Cardo Group has successfully delivered large-scale retrofit projects that serve as blueprints for national replication. Their holistic delivery model—combining technical delivery with social value initiatives—has demonstrated measurable outcomes including:
These results show that zero carbon housing retrofit is not only possible—it’s scalable, affordable, and impactful when delivered by experienced partners.
