The House of Lords has rejected Labour’s controversial “reserve power” legislation for a second occasion, preventing the Government from forcing pension schemes to allocate substantial portions of retirement savings into private markets. This latest parliamentary defeat underscores deepening concerns among peers and pensions professionals regarding the proposed mandation framework.

[The Pension Schemes Bill](https://www.share-talk.com/labour-secures-vote-on-powers-over-private-pensions/), which contained the disputed reserve power, passed through the House of Commons last week following approval by Labour MPs. The measure would have granted ministers authority to compel pension schemes to invest up to 10 per cent of their assets in private markets, with at least 5 per cent directed toward British investments, until 2035. The House of Lords rejected this proposal by a majority of 219 votes to 144, returning the legislation to the Commons through the parliamentary procedure commonly known as “ping pong”.

The Government’s attempt to introduce a watered-down version of the original proposal failed to satisfy legislative opposition. Baroness Altmann, former pensions minister, characterised the Government’s approach as requiring political actors to acknowledge they had received explicit guidance that their plans were fundamentally flawed. Helen Whately, shadow work and pensions secretary, described the rejection as an “embarrassing defeat” and stated that the Government had sought to disguise what remained a “reckless reach into people’s savings” through cosmetic amendments.

The reserve power, originally proposed in summer 2024, provoked substantial resistance from pensions professionals who argued the measure would remove investment decisions from qualified experts and expose retirement funds to unnecessary risk. Baroness Altmann articulated specific concerns regarding the inherent dangers of mandating high-risk private asset purchases within prescribed timeframes, warning of potential asset bubbles, investor losses, and diminished pension outcomes. She emphasised that Government policymakers lack the expertise required to make long-term investment decisions, particularly when timing constraints are artificially imposed on illiquid asset allocations.

The Treasury’s broader policy framework rests upon the Mansion House Accord, signed between the Government and 17 major pension providers representing 90 per cent of active savers’ defined-contribution pension savings. Under this voluntary agreement, participating providers committed to investing at least 10 per cent of their portfolios in economically beneficial assets, including infrastructure, property, and private equity, by 2030, with 5 per cent earmarked for British investments. This existing accord rendered the mandatory powers superfluous, according to critics who questioned the Government’s rationale for pursuing statutory intervention.

Legal and fiduciary obligations present a compelling argument against mandation. Pension scheme trustees operate under statutory duties to prioritise their members’ financial interests; compulsory investment directives would compromise this fundamental principle by subordinating investment decisions to political rather than actuarial considerations. Tom Selby of AJ Bell characterised the Government’s approach as an attempt to utilise pensioners’ assets to resolve broader economic challenges, whilst Lisa Picardo of PensionBee warned that consumers would bear the financial consequences should ministerial predictions regarding private market returns prove inaccurate.

The duration of the proposed reserve power until 2035 attracted additional scrutiny from parliamentary peers. This extended timeline would persist for six years beyond the expected date of the next general election, effectively insulating the powers from electoral accountability and allowing a future Government to exercise discretionary control over pension investments regardless of changing economic circumstances.

The Bill will return to the House of Commons, where Government ministers are expected to propose further amendments in their efforts to secure passage before the forthcoming King’s Speech. The Telegraph campaign against mandation, launched in recent weeks, has contributed to sustained public awareness regarding the proposal’s contentious nature. As the parliamentary debate continues, the tension between Government economic objectives and the protection of pensioners’ retirement savings remains unresolved.
