The Pensions Policy Institute (PPI), commissioned by the Association of British Insurers (ABI), has published a report examining retirement adequacy gaps across housing tenure, household structure and auto-enrolment. Building on the Pensions Commission's Interim Report (2026), the report examines how housing tenure, household composition and pension saving interact to shape retirement outcomes. The report projects nearly two million more pensioner households will be renting by 2044. Single pensioners are approximately twice as likely as couples to fall below minimum retirement living standards, and divorced women aged 60–64 hold median pension wealth of just £35,000. On automatic enrolment, the headline 8% minimum contribution rate equates to an effective rate of just over 3% for workers near the £10,000 earnings trigger. For earners above £18,700, raising contributions to 12% has the greatest impact, while for lower earners, removing the earnings trigger and lower earnings limit is more effective. The report calls for a package of targeted reforms, including higher contributions, carer credits and means-tested benefit reform, alongside integrated housing and welfare policy to address adequacy gaps for renters, carers and lower-income workers.
