Improving Energy Efficiency and Reducing Fuel Poverty in Housing Associations

How government funding helps housing providers cut carbon and energy costs

Social housing providers across the UK are delivering major energy upgrades through targeted government funding schemes. These programmes enable housing associations to improve insulation, install low-carbon heating, and raise Energy Performance Certificate ratings in some of the country’s least efficient homes. The result is lower carbon emissions, reduced fuel bills, and healthier living conditions for vulnerable residents.

Funding mechanisms such as the Social Housing Decarbonisation Fund and the Home Upgrade Grant prioritise a fabric-first approach. This means improving a building’s thermal envelope before upgrading heating systems. Consequently, providers can address the worst-performing properties first while meeting national decarbonisation targets.

Housing associations manage a substantial share of the UK’s social housing stock. They face considerable pressure to decarbonise ahead of the 2050 net zero deadline. Buildings must eliminate direct emissions by 2048 according to the Climate Change Committee’s roadmap. Therefore, upgrading older properties with low EPC ratings presents both a regulatory obligation and a significant financial challenge.

The sector has committed to invest approximately £70 billion in planned upgrades. An additional £36 billion will be required to achieve full decarbonisation. However, government schemes now provide critical support to bridge this funding gap and accelerate progress.

Social Housing Decarbonisation Fund drives fabric-first upgrades

The Social Housing Decarbonisation Fund, recently rebranded as the Warm Homes: Social Housing Fund, allocated £800 million over three years initially. Wave 3 now provides £1.29 billion for the period 2025 to 2028. This funding targets homes below EPC C, focusing on insulation improvements and low-carbon heating installations.

Housing associations apply directly for this funding through competitive bidding rounds. Importantly, landlords must contribute at least one-third of project costs. This requirement ensures cost-effectiveness and encourages realistic, deliverable proposals.

The fund emphasises upgrading insulation before installing new heating systems. Properties must achieve EPC C as a minimum standard. Additionally, heating demand should fall to 90 kilowatt-hours per square metre per year. These technical requirements ensure that upgrades deliver genuine long-term energy savings.

Recent funding waves have built on earlier successes by prioritising the worst-performing properties. Guidance now encourages integration of solar photovoltaic panels to improve project viability. As a result, housing providers can maximise carbon reduction while controlling installation costs.

Home Upgrade Grant targets off-gas rural properties

The Home Upgrade Grant offers £950 million in total funding. Phase 2 provides £700 million running from April 2023 to March 2025. This scheme specifically supports low-income households living in off-gas homes with EPC ratings of D or below.

Sixty percent of this funding is ringfenced for rural areas. These properties often lack access to mains gas and rely on expensive heating oil or electricity. Therefore, the grant funds insulation improvements, air source heat pumps, and solar panels to reduce both carbon emissions and energy costs.

Local authorities administer the Home Upgrade Grant. They identify eligible households and coordinate installations through approved contractors. This localised delivery model ensures that funding reaches the most vulnerable households in hard-to-treat properties.

From April 2025, the Warm Homes: Local Grant will succeed this scheme. It will continue providing energy efficiency measures and low-carbon heating to low-income households through local authority partnerships. This ensures continuity of support for off-gas properties beyond the current funding round.

Energy Company Obligation complements government grant schemes

The Energy Company Obligation scheme, now in its fourth phase as ECO4, tackles fuel poverty through insulation and efficient heating upgrades. Unlike direct government grants, ECO4 places obligations on large energy suppliers to fund improvements for low-income and vulnerable households.

Housing associations can access ECO4 funding to supplement their own investment programmes. This helps providers deliver warmer, cheaper-to-heat homes while reducing long-term maintenance costs. Furthermore, combining ECO4 with grant funding maximises the scope and impact of individual projects.

ECO4 funding has contributed to measurable improvements in social housing. Fuel poverty among housing association residents fell from 40.3 percent in 2010 to 18.4 percent in 2019. This demonstrates the cumulative effect of sustained investment in energy efficiency across the sector.

Housing providers exceed regulatory standards in new builds

Some housing associations are voluntarily exceeding minimum regulatory requirements in new construction projects. Believe Housing, for example, targets an 80 percent reduction in operational carbon emissions by 2025. Their new builds achieve EPC A ratings without gas boilers, incorporating heat pumps, solar panels, electric vehicle charging points, and battery storage.

Kate Abson, director at Believe Housing, acknowledged that these measures represent a significant cost to the business. However, she stated: “We think that is the right thing to do.” This approach positions the organisation ahead of regulatory changes while delivering long-term savings for residents.

Construction costs have risen substantially in recent years. Nevertheless, forward-thinking providers continue to invest in high-performance buildings. This strategy reduces future retrofit costs and ensures compliance as regulations tighten towards the 2048 direct emissions deadline.

Southern Housing and other major providers have undertaken similar commitments. Projects such as the High Road Ilford development achieved 80 percent EPC A ratings through comprehensive heat pump installation and insulation upgrades. These examples demonstrate that high energy performance is achievable at scale in social housing.

Sector commits billions to decarbonisation despite funding gaps

Housing associations have committed approximately 72.5 percent of the sector to emissions reduction targets. Planned investments total around £70 billion for currently scheduled upgrades. Full decarbonisation will require an additional £36 billion beyond existing commitments.

This investment addresses both regulatory compliance and resident welfare. Housing accounts for 22 percent of UK carbon emissions. Therefore, social housing providers play a crucial role in meeting national climate targets. Moreover, improved energy efficiency directly reduces fuel poverty and improves health outcomes.

Funding gaps remain a significant challenge. Government grant schemes provide essential support but do not cover the full cost of sector-wide decarbonisation. Consequently, housing associations must balance ambitious carbon targets against financial sustainability and other investment priorities such as new supply.

Supply chain constraints also affect delivery timelines. The retrofit sector faces skills shortages and capacity limitations. As demand increases, providers must plan projects carefully to secure qualified contractors and avoid cost inflation.

Upgrades deliver carbon savings and bill reductions for residents

Comprehensive retrofit projects combining fabric improvements with heat pump installation can reduce carbon dioxide emissions by 90 percent compared to baseline performance. These upgrades also deliver substantial reductions in energy bills for residents.

Improved insulation reduces heat loss through walls, roofs, and windows. This lowers the energy demand of the property before any heating system upgrade. Subsequently, installing an efficient heat pump or other low-carbon heating maximises the carbon and cost savings.

Residents benefit from warmer homes with more stable temperatures. Better insulation eliminates cold spots and reduces condensation. This improves comfort and reduces health risks associated with cold, damp housing.

Lower energy bills directly address fuel poverty. Many social housing residents live on low incomes and struggle to afford adequate heating. Therefore, energy efficiency upgrades provide both immediate and long-term financial relief for vulnerable households.

• Leading providers now build to EPC A standards with heat pumps, solar panels, and battery storage, exceeding minimum regulations ahead of 2025 changes.

Planning retrofit projects alongside regulatory deadlines

Housing providers should assess their current stock against EPC C requirements and identify the worst-performing properties for early intervention. Prioritising homes with ratings of D or below maximises eligibility for current funding rounds. Additionally, properties with high heating demand offer the greatest potential for carbon and cost savings.

Successful funding applications require robust project planning and realistic cost estimates. Providers should engage with specialist retrofit coordinators early in the process. Furthermore, demonstrating the capacity to deliver projects on time and within budget strengthens competitive bids.

Combining multiple funding sources can increase project scope and impact. For example, blending Social Housing Decarbonisation Fund grants with ECO4 funding and internal resources enables more comprehensive upgrades. This approach maximises value while spreading financial risk.

Tenant engagement remains essential throughout the retrofit process. Residents need clear communication about the benefits of upgrades and what to expect during installation. Moreover, effective engagement reduces disruption and ensures that residents can operate new heating systems efficiently.

Supply chain planning has become increasingly important as retrofit demand grows. Providers should establish relationships with qualified contractors well in advance of project commencement. This helps secure capacity and avoid delays caused by contractor availability or skills shortages.

Monitoring and reporting carbon savings demonstrates the impact of investment. Housing associations should track energy performance data before and after upgrades. Consequently, this evidence supports future funding applications and demonstrates progress towards organisational net zero commitments.

Looking ahead, regulatory requirements will continue to tighten. Properties must achieve low-carbon heating and high energy efficiency by 2033. Therefore, providers should develop long-term asset management strategies that align retrofit programmes with these deadlines while maintaining financial sustainability.
