AI Conversational Search pilot for Independent Public Sector Body

Organisation Type: Independent Public Sector Body
Focus: Improving public access to complex information using AI conversational search

The Challenge

A government-backed public body with a regulatory function maintains a detailed and high-traffic website. It includes:

  • Reports, policies, procedures, and legislation
  • Information for the public on complaints and rights
  • Resources for legal professionals, researchers, and journalists

The organisation serves a wide range of users, each with different needs — but they all faced the same issue: finding the right information was slow and frustrating. Standard site search struggled to surface relevant results, especially from lengthy reports or nested PDF documents.

The Solution: AI Conversational Search Powered by LLM + RAG

The team partnered with PretaGov to trial a natural language search agent. The goal was to allow users to ask their questions in plain English and receive fast, clear, and accurate answers — using only information already published on the website.

Key capabilities included:

  • LLM (Large Language Model) to understand a wide variety of natural questions
  • RAG (Retrieval-Augmented Generation) to ensure responses came only from existing, approved web and document content
  • Citations and links included with every answer
  • Tuning and oversight tools to refine responses over time

Example Questions Answered

“How do I make a formal complaint?”
“Where can I download xxx report published on 1 July?”
“What powers are available under the oversight legislation?”

Instead of manually searching documents or clicking through menus, users received immediate answers linked to authoritative content.

Applicability to UK Councils

UK councils often face similar challenges:

  • Large volumes of critical service content
  • A diverse user base (residents, professionals, advocacy groups)
  • Underwhelming results from traditional search or legacy chatbots

AI conversational search enables councils to handle:

“When is my next bin day?”
“How do I object to a planning application?”
“What housing support is available?”

And return immediate, citation-backed responses — using your own content.
