An Aon simulation using artificial intelligence tools to provide investment advice to those making retirement decisions delivered mixed results, with clear explanations sometimes provided, and also occasions of incorrect calculations being supplied.
Aon ran real -life cases through AI via its in‑house platform, looking to replicate the questions, uncertainties, and decision points a member might face.
For these members, the firm then compared the AI outputs with the advice they had actually received, including adviser call transcripts and recommendation reports.
At its best, AI produced clear explanations and intuitive support that could work alongside a human conversation. However, Aon also identified material risks, such as incorrect calculations, inconsistent recommendations, and a tendency to present speculation as fact.
The Aon report also noted that increasing numbers of DC pension schemes are providing members with access to retirement planning tools and workshops. It also claimed that for many members, the volume and complexity of information needed for retirement planning reinforces the need for clear, trusted support. Where this is not easily available, it may push members towards AI tools as an additional ‘explainer’.
Kelly Hurren, a partner at Aon in the UK, says: “The advice gap remains a significant challenge in UK retirement planning, and Aon has supported many schemes and employers in addressing it.
“It’s clear that AI will become a significant part of how members navigate retirement. It has the potential to improve understanding and engagement, but it also introduces new risks. We believe that schemes and employers which recognise this early can shape and support strategies that blend the best of digital capability with human expertise.”
For its AI analysis, undertaken in early 2026, Aon used a secure version of GPT 5.1.
