Sustainability-Linked Loans Face Scrutiny Over Cost and Impact

A new report from Newbridge Advisors has cast fresh light on the challenges facing sustainability-linked loans (SLLs) in the UK social housing sector.

Based on feedback from 28 housing associations and six lenders, the study reveals growing concern over the cost-effectiveness and transparency of these ESG-tied financial products.

While 38% of housing associations said they would consider taking out new SLLs, only 10% felt the setup and monitoring costs were justified by the environmental and social outcomes achieved.

Respondents cited high assurance fees, inconsistent KPI frameworks, and limited value exchange between lenders and borrowers.

Lenders, while generally supportive of the sector’s ESG ambitions, acknowledged the need for reform.

Many called for clearer strategies, stronger internal governance, and more robust impact reporting from housing providers.

Newbridge’s report recommends several changes, including:

• Simplified and standardised KPI frameworks
• Reduced legal and assurance costs
• Greater alignment between ESG goals and financial incentives

Despite the criticism, SLLs have played a significant role in channeling billions into sustainable housing projects. But the report warns that without evolution, the product risks losing relevance in a maturing market.

Janani Paramsothy, associate director at Newbridge, said: “Funding alone won’t deliver net zero and social impact goals — organisational culture and strategy matter just as much.”
