Pension trade-off: expert warns £64,000 lump sum may not beat higher local government pension

Former pensions minister Steve Webb has advised that a member of the Local Government Pension Scheme (LGPS) weighing a larger tax-free lump sum of about £64,000 against a higher monthly pension should be cautious, saying the scheme’s conversion terms make the lump-sum option poor value for many retirees.

The reader, aged 60, outlined options in which taking a standard pension would produce roughly £1,144 a month with a £15,000 tax-free lump sum, while electing for a larger lump sum would reduce the monthly pension to about £800 — effectively trading an extra £49,000 in cash for a reduction of £344 per month (about £4,100 a year) in guaranteed pension income.

Webb explained that the LGPS applies a commutation factor of roughly 12:1 in this case, meaning the member gives up £1 a year of pension for every additional £12 of lump sum. He described that ratio as "amongst the worst to be found in the DB [defined benefit] pensions system," and noted it contrasts with many private-sector schemes that impose a smaller reduction in pension for each pound of extra lump sum.

A key element in Webb’s analysis is life expectancy. He cited Office for National Statistics figures that a 60-year-old woman in average health can expect to live about 27 more years. Under those assumptions, exchanging pension income for lump sum cash typically produces a lifetime shortfall: £12 in one-off cash versus roughly £27 of forgone pension over an average lifespan, before taking tax and annual inflation uprating into account.

Webb also illustrated the point with market annuity figures. Using about £64,000 to buy an inflation-linked annuity that provides survivor benefits — broadly comparable to the LGPS pension being given up — would currently generate roughly £3,000 a year, or about £250 a month, rising at about 3% a year. That compares unfavourably with the £344 per month the member would forfeit to secure the larger lump sum.

Tax treatment and lifetime allowances feature in Webb’s guidance. He underscored that pension tax rules allow a tax-free lump sum, but there is a lifetime limit on tax-free lump sums (currently £268,275). He said that for many members who do not have large other pension pots this limit will not be a binding constraint.

Beyond the arithmetic, Webb urged readers to consider personal circumstances. If a retiree has an immediate need for capital — for example to pay high-interest debts, fund a major home project, support family members, or finance an early, higher-spending phase of retirement — taking more tax-free cash can be sensible despite the long-term cost. Conversely, someone who needs replaceable, inflation-protected regular income to cover rent or ongoing expenses will often be better served by a higher regular pension.

Webb highlighted that the LGPS’s relatively unfavourable commutation factor means members surrender a substantial amount of guaranteed, inflation-linked income in exchange for cash. He cautioned that inflation uprating on the pension magnifies the long-term cost of swapping income for a lump sum.

He reiterated that his comments are guidance rather than personalised financial advice and that the best choice depends on each individual’s broader financial picture, including state pension entitlements, other savings, housing situation and family commitments. He also pointed readers toward free, government-backed help: MoneyHelper, which provides guidance on pensions and can be contacted via 0800 011 3797.

Webb, who left the Department for Work and Pensions after the 2015 election and is now a partner at actuary and consultancy Lane Clark & Peacock, invited readers to submit pension questions to pensionquestions@thisismoney.co.uk, while noting he cannot answer every enquiry and his published responses do not constitute regulated financial advice.
