We examine the extent to which owner-occupiers in their 50s and 60s change their private pension saving when they complete repayment of the mortgage on their primary residence. Using panel data from a household survey, the English Longitudinal Study of Ageing, we identify those who completed repayment of their mortgage as anticipated two years prior. Despite mortgage expenditures falling by over £200 per person on average, there is little resulting change in average pension saving. This is because only a small minority of individuals react – the probability of an individual increasing their monthly pension saving by more than £150 increases by only 5 percentage points on completing repayment of a mortgage. This suggests that if policymakers wish to influence behaviour in order to increase private pension saving, interventions targeted at those completing their mortgage repayment could be a tractable approach. Such individuals would be able to increase pension saving while maintaining spending at recent levels.
