Public sector organizations across the United Kingdom are experiencing a notable rise in correspondence produced by generative artificial intelligence, leading to what some observers call an "AI clog." This phenomenon, which began as a minor trend in 2024, has escalated into a significant operational challenge for various public bodies. Hollie Wickens, a senior caseworker in a Labour MP's office, stated that approximately half of the emails her office receives are generated by AI, making requests and complaints more complex and time-consuming to address.Before the widespread availability of tools like ChatGPT, Claude, and Gemini, drafting formal complaints or objections typically demanded considerable effort, including research and specialized knowledge. Generative AI tools now enable individuals to create professional-sounding legal demands quickly, acting as a free personal assistant. While AI offers productivity gains in some economic sectors, contributing to better-than-expected UK GDP growth this year, it has concurrently inundated public bodies with an increased workload.Local authorities are receiving more complaints concerning social services, uncollected rubbish, parking fine appeals, and development objections. Deborah Evans, head of Lawyers in Local Government, noted that the average complaint length has increased from around two pages to ten times that, with some reaching up to 200 pages. These AI-generated complaints are often "unnecessarily verbose" and may contain "embellished or exaggerated claims" that portray minor incidents as major offenses. A common issue is that these complaints frequently omit the desired resolution from the complainant.The Information Commissioner's Office (ICO), the UK's information rights watchdog, observed that AI-generated requests can be excessively long, repetitive, and contain irrelevant comments or misdirected demands, making it difficult to identify the specific information being sought. Furthermore, chatbots may cite laws or case precedents that are not applicable within the UK jurisdiction or invent information entirely.The influx of AI-generated correspondence is also impacting parliamentary offices. Vonnie Sandlan, head of office for Labour MP Graeme Downie, reported that her staff are "exhausted" from dealing with the surge in requests. Her office has decided to stop responding to automated "click to email your MP" campaigns to prioritize individual constituent requests. Transport for London (TfL) received a record 4,769 freedom of information requests in 2025-26, a 5% increase from its previous peak in 2023-24, with a noted increase in appeals believed to be AI-generated.Some public bodies are exploring the use of AI tools to manage this volume. Wiltshire council is investigating AI to summarize lengthy emails and draft initial responses, while Stroud district council has discussed using Microsoft's Copilot for report writing and information presentation. However, concerns exist that relying on AI to process AI-generated correspondence could lead to a loss of the "human touch." Some ombudsman services are considering implementing word limits for complaints or using online forms with attachment restrictions to control the volume of submissions.
