Nationwide Expands Green Home Improvement Loans to Support UK Decarbonization

Nationwide Building Society is significantly expanding its commitment to green home improvements by doubling the number of households eligible for its 0% Green Additional Borrowing scheme. This move aims to support the UK’s decarbonization efforts and aid homeowners reduce their energy bills.

Increased Access to 0% Green Loans

Starting March 2026, Nationwide will extend the scheme to cover up to 10,000 households, a substantial increase from the initial 5,000 households supported since the scheme’s launch in June 2023. Eligible borrowers can access interest-free loans ranging from £5,000 to £20,000 to fund energy-efficient home improvements. Nationwide has already lent approximately £60 million through this initiative, with an average loan size of around £13,000.

Popular Home Improvements

The funds are primarily being used for common energy-saving upgrades, including:

• Solar panel installations
• Insulation upgrades
• Replacement windows

Regional Uptake

The South West region of England has demonstrated the highest adoption rate of the scheme, accounting for 16% of all completed green borrowing cases. The Outer Metropolitan and Outer South East regions follow closely, each representing 12% of completions. Mortgage Soup reports these regional trends.

Government Partnership and Wider Impact

Nationwide’s expansion aligns with the government’s new Green Home Finance Strategic Partnership, part of the broader Warm Homes Plan. This partnership brings together financial institutions, the energy sector, and consumer groups to scale up green home finance options. The collaboration aims to address the significant role housing plays in the UK’s emissions profile, with residential buildings accounting for roughly one-fifth of England’s total emissions. Mortgage Strategy highlights Nationwide’s commitment to this partnership.

Research conducted by Nationwide and WPI Economics suggests that upgrading all homes to an Energy Performance Certificate (EPC) band C or above could reduce residential housing emissions by up to 47%.

Eligibility and Application

The additional borrowing is available up to a maximum of 90% loan-to-value (LTV) and can be repaid over a two- or five-year term. Nationwide mortgage customers can apply for the funding after making their first mortgage payment.

Industry Response

Mary-Lou Press, president of industry body NAEA Propertymark, emphasized the importance of initiatives like this, stating they “help homeowners reduce their energy bills and carbon emissions, but also play a crucial role in improving the overall sustainability of the UK’s ageing housing stock.” She also called for broader and more accessible green financing solutions across the market to benefit more property owners.
