UK Public Bodies Face Heavy Backlog From AI-Generated Complaints

UK public bodies, local authorities, and parliamentary offices are dealing with a massive surge in complaints, legal challenges, and freedom of information requests generated by artificial intelligence tools. The influx is overwhelming staff and stretching public resources thin.

Before the widespread availability of generative chatbots, writing a formal complaint or appeal required significant personal effort and research. The rise of free AI tools now allows anyone to quickly produce long, formal-sounding documents that mimic legal arguments. Researchers at several academic centers have labeled this sudden flood of automated correspondence "agentic flooding," while commentators refer to the wider issue as "AI clog".

Local government legal representatives report that complaints are significantly longer than they used to be. While complaints previously averaged about two pages, many now span 10 times that length, with some reaching up to 200 pages. Officials note that these AI-assisted submissions often quote laws and legal cases from outside local jurisdictions or include inaccuracies, yet human staff are still required by watchdogs to read and answer them.

The rising volume is also hitting public transport operations and parliamentary offices. Transport for London received a record 4,769 freedom of information requests in the 2025-26 period, alongside an increase in appeals containing technical and inaccurate AI assumptions. Parliamentary staff report exhaustion from handling double their usual casework, leading some offices to stop responding to automated email campaigns.

Employment tribunals are experiencing similar pressures, with single-claimant cases rising and mounting legal costs for employers. Experts note that AI-generated employment grievances frequently use intimidating language while failing to state what resolution the complainant actually wants.

To cope with the workload, some local councils and ombudsman services are introducing word limits, online templates, or exploring the use of AI tools to summarize messages. However, experts warn that filtering automated messages with more automation risks losing a human touch and diverts public funds away from vital community services.

Summary

The rapid spread of AI-generated complaints is overwhelming public services and local governments with long, complex documents that take hours for human staff to review. Because public budgets are fixed, the time and money spent processing these automated messages pulls resources away from core community needs.
