Expert warns swapping local government pension for larger tax-free lump sum can leave retirees worse off
Steve Webb says a 12:1 commutation factor in many public-sector schemes means a £64,000 lump sum is unlikely to replace the income given up by cutting a defined-benefit pension
A former pensions minister has told a 60-year-old local government employee that taking a larger tax-free lump sum in place of regular defined-benefit pension income is unlikely to be financially advantageous in most cases.
Steve Webb, writing in a consumer column, set out the maths after a reader said they could choose between a roughly £15,000 lump sum with a £1,144 monthly pension or a £64,000 lump sum with a £800 monthly pension. The difference amounts to an extra £49,000 of tax-free cash in exchange for foregoing about £344 a month, or just over £4,100 a year, in pension.
Webb explained that the Local Government Pension Scheme applies a commutation factor of roughly 12:1 in this case — meaning the scheme reduces the annual pension by £1 for every £12 of additional lump sum taken. That ratio, he said, is “amongst the worst to be found in the DB pensions system,” with many private-sector schemes charging a smaller reduction.
He illustrated the effect using life expectancy figures from the Office for National Statistics. A 60-year-old woman in average health might expect to live about 27 more years, so exchanging amounts that are priced at a 12:1 ratio typically works out poorly over a normal lifetime. Even after accounting for income tax — which makes the lump sum effectively worth 100% upfront while pension payments are taxable — the long-run loss in inflation-linked pension income tends to exceed the one-off gain.
Webb also considered whether the £64,000 lump sum could be invested to replicate the £344-a-month income given up. Using current annuity rates for a 60-year-old seeking a joint-life income that rises roughly in line with inflation, he estimated a taxable lifetime annuity would pay about £3,000 a year, or roughly £250 a month, with a 3% annual uplift. That is materially lower than the £344 monthly pension the reader would forgo.
The column noted additional distinctions between annuities and defined-benefit pensions. The local government pension would typically increase with inflation each year; an annuity that starts lower would need higher uplift or investment returns to match that inflation protection. Webb said that the calculation above assumed a surviving partner’s benefit, as would be provided by the reader’s scheme.
Despite the arithmetic, Webb cautioned that individual circumstances can shift the balance. Immediate needs for capital — such as clearing high-interest debts, funding large home repairs, or assisting family members with house deposits or education costs — can make a larger lump sum attractive. Likewise, homeowners who can meet regular expenses from other sources may prefer a lump sum to fund specific, front-loaded spending in early retirement. Conversely, those who expect continuing housing costs, rely on regular outgoings, or value predictable inflation-protected income may favour the larger ongoing pension.
He reminded readers of the lifetime limit on tax-free pension cash — currently £268,275 — but said that amount was unlikely to be a constraint for someone whose local government pension is their main or only scheme.
Webb declined to offer regulated financial advice and stressed that his comments were general guidance rather than personalised recommendations. He encouraged readers to weigh longevity, tax position, spending needs, and dependence on other income when deciding between lump sums and lifetime pension income.
Readers seeking independent guidance were pointed to MoneyHelper, the Government-backed service that provides free pensions assistance, and were given a contact number, 0800 011 3797. Webb invited further questions to pensionquestions@thisismoney.co.uk but noted he could not answer every reader individually.
The correspondence highlights a broader issue in defined-benefit pensions: scheme-specific commutation factors can make straightforward comparisons difficult. As employers and schemes set conversion terms, members offered lump-sum options should model the long-term income consequences, consider protected inflation linkages, and seek independent financial advice where appropriate before making irreversible choices.
