Background
Northumbrian Water Limited, the sponsoring employer of the Northumbrian Water Pension Scheme, brought a Part 8 claim seeking directions on Rules 4.9 and 4.10 of the Scheme’s WPS Section. Those rules govern increases to pensions in payment and deferment attributable to service before 1 January 2008.
The rules guarantee annual increases equal to RPI capped at 5%. When RPI exceeds 5%, Rule 4.9 provides mechanisms for paying the excess, subject to the Scheme’s ability to do so without increasing the employer’s ordinary annual contributions, or for paying a prudent portion and potentially making up a shortfall later. RPI exceeded 5% during 2021–2023, prompting a dispute between the employer and trustee while the Scheme remained substantially underfunded. The issues affected approximately 2,003 members and had an estimated actuarial value of about £26 million.
The Court’s Holding
The High Court held that the full excess above the guaranteed 5% increase is not triggered merely because there is a realistic possibility that it can be paid without higher ordinary annual employer contributions. The trustee must be satisfied that there is no material uncertainty that the increase can be paid without such a contribution increase. That construction allowed the full-increase, prudent-partial-increase, and later catch-up provisions to operate coherently and reflected their common concern with affordability and the security of Scheme benefits.
The assessment must be made when the increase is due, using its cost at that date and taking account of all reasonably foreseeable future events. Because the Scheme was desegregated in 2010, the trustee should not notionally allocate assets to the WPS Section or treat its members as exclusively entitled to surplus resources. It must consider known claims for increases across all sections and the conditions attached to those claims. The court also confirmed that catch-up revaluation applies only to members whose pensions were deferred at the original increase date and remain deferred when the catch-up is applied.
Key Takeaways
- An RPI increase above 5% does not automatically entitle WPS Section members to the entire excess.
- The trustee must find no material uncertainty that paying the full excess will avoid an increase in ordinary annual employer contributions.
- Affordability must be assessed Scheme-wide at the payment date, considering foreseeable events, competing section claims, and the security of other benefits.
Why It Matters
The decision supplies practical guidance for trustees and sponsoring employers interpreting conditional pension-indexation provisions. It distinguishes guaranteed increases from additional increases whose payment depends on scheme resources and employer-contribution consequences.
It also confirms that desegregating a multi-section pension scheme can require a scheme-wide assessment of competing benefit claims, even when the increase rule applies to only one section. The judgment resolved the construction questions but left the trustee to apply those directions to the relevant increases.
