About the research

Rigorous and independent.

The Banking Barometer is Perigon Partners' annual, independent assessment of sustainability and strategic reporting across UK and Irish financial services. Our cohort spans the full breadth of the sector: from small fintechs to the largest full service banks, from building societies to specialist and challenger banks.

The primary purpose of the research is to provide leaders and sustainability teams in UK financial services with impartial, reliable, market-wide benchmarking data to support planning, prioritisation and board engagement. A secondary purpose was added from 2025: providing insights to leaders and strategy teams on the relative robustness of their strategic frameworks and approach to AI.

The Banking Barometer is Perigon Partners' annual, independent benchmark of sustainability, climate and strategic reporting across UK and Irish financial institutions. Published since 2023, it analyses public disclosures from annual reports, covering materiality, ESG strategy, GHG emissions, climate targets, and (from 2025) business strategy quality and AI maturity. It is the only benchmark spanning the full breadth of the UK banking sector: from small fintechs to the largest full service banks, from building societies to specialist and challenger banks.

65% of the 57-institution cohort: 37 banks have a confirmed net zero target as of FY2024. 83% target 2050. This is up from 34 institutions in FY2023. Despite media narratives of retreat, Perigon's data shows the sector is making net positive progress on climate targets.
37% (21 of 57) had published a climate transition plan by FY2024, more than doubling from 9 the prior year. 90% of full service banks now have a plan. Building societies lag significantly. In 2023, the figure was near-zero.
The 2025 Barometer scored AI maturity, based on the mentions within the annual report, on a six-level scale (0=Absent to 5=GenAI Native). 1 in 4 banks made no mention of AI in their annual report. Only 9 banks' disclosures (16%) suggested they were at Level 3 or above and no banks' disclosures suggested they were yet at Level 5. Publicly listed institutions were 17.6x more likely to score higher than member-owned building societies.
