The 18th edition of the Judicial College Guidelines

Overview

Once again, the editors have anchored the Guideline uplift to RPI, adjusting figures only to August 2025, and expressly declining to engage in the debate over whether RPI remains an appropriate index at all. Critics have pointed out that by continuing to rely on RPI, despite the existence of alternative indices, the Guidelines embed a valuation methodology that may lag behind inflationary pressures. Instead, the editors have specifically stated that a change to a different index falls to the courts to determine.

More striking is the repeated reminder that the published figures may require further adjustment at the point of assessment to reflect ongoing inflation. This is also a reminder that, despite the heavy reliance on the Guidelines, responsibility for valuation of injuries ultimately lies with judges. It remains the case that the Guidelines should only be a starting point for insurers and practitioners in setting adequate reserves.

Significant changes 

The Guidelines’ sections on epilepsy, sexual and/or physical abuse have been substantively revised. These updates are not merely editorial corrections; they reflect evolving medical understanding, language, and societal awareness in respect of these types of injuries. This includes, for example, the replacement of the terms ‘grand mal’ and ‘petit mal’ with more up to date terminology.

The introduction of an awards bracket for miscarriage is particularly notable. By explicitly recognising miscarriage as a distinct category of compensable harm, the Guidelines move closer to capturing experiences that have historically sat awkwardly within general damages frameworks. This development invites claimants to introduce more nuanced evidence and argument.

Only a guide

The Guidelines continue to emphasise that they are not binding, and that no two injuries are ever truly the same. This principle has long underpinned valuation of claims, yet it can sit in tension with the Guidelines when too much reliance is placed on the same in negotiations, reserving and litigation strategy.
The absence of new guidance on multiple injuries, with reliance instead on established authority reinforces judicial reluctance to over systematise damages assessment. 

Conclusions

More than any single uplift or amendment, the 18th edition underscores a broader truth: the Guidelines are increasingly a conversation rather than a conclusion. They reflect economic change, social awareness, and legal caution, but stop short of resolving the tensions these forces create. Inflation is acknowledged but not solved. New harms are recognised but carefully bounded. Discretion is preserved, even as reliance on Guideline figures intensifies.

For insurers and claims professionals, the message is clear. The Guidelines remain indispensable, but they cannot be treated as a complete answer. Given that awards can be amended to reflect inflation since August 2025, caution should be exercised when reviewing reserves and a watching brief over any future increases in inflation is recommended.

That said, the 18th edition of the Guidelines does exactly what Guidelines should do: it guides, but it also challenges. And in an unsettled economic climate, that challenge may prove far more significant than the headline percentage increase.
