UK Audit Finds Climate-Reporting Gaps as Prison Flood Risks Expose Public-Service Pressures

A new review by the United Kingdom's National Audit Office (NAO), published on 2 November 2026, finds that many central government bodies are still developing the information needed to explain how climate change could affect public services and public finances. The review examined 31 organisations' 2025–26 disclosures: 25 central government bodies using HM Treasury guidance and six reporting under company-law requirements. It was a selected audit sample, not a finding that all UK public bodies had failed.

The NAO says that central government reporting has improved on governance and risk management, but that many bodies still provide too little information about the operational, strategic and financial consequences of climate risks. Among 15 central government bodies that identified climate change as material, the full audit found that only five completed a full strategy disclosure. The auditor also said only five of those 15 provided a relevant target. These are shortcomings in reporting and oversight, not evidence of corruption or quantified losses.

A comparison with the original HM Prison and Probation Service (HMPPS) annual accountability report, published on 29 October, shows why the distinctions matter. HMPPS reports that 89% of prisons in its assessed estate are at high or very high risk of flooding under its present-day risk assessment. It separately lists 71% of prison sites at high or very high risk of overheating under a 2°C warming scenario for 2020–2039. The second figure is a scenario-based exposure estimate, not a count of prisons that overheated in 2026. Its flood assessment does not mean 89% of prisons have already flooded.

HMPPS acknowledges that it has not yet set formal climate-adaptation objectives or targets. It also reports work already under way, including flood-risk assessments, a climate resilience plan and pilot sustainable-drainage interventions. The agency says it intends to develop an action plan in 2026–27 and use its second climate-risk assessment to guide future decisions. Those commitments are important counterevidence to any claim that officials have taken no action, although plans alone do not establish that risks have been reduced.

The parliamentary Environmental Audit Committee chair, Toby Perkins, responded on 2 November that government needed to expand its assessment and disclosure of climate risks. He said his committee would continue scrutiny as it began work on climate adaptation. That is a political oversight response, not an independent finding of unlawful conduct.

The accountability question is therefore measurable: whether agencies move from identifying flood, heat and service-continuity risks to setting verifiable adaptation targets, funding decisions and reported outcomes. Future reviews should distinguish planned investment from money committed or spent, and should test whether risk exposure and disruption actually decline. The NAO review and the HMPPS figures establish a documented reporting gap and physical exposure; they do not establish negligence, fraud or a proven failure at any named prison.
