- UFPLS, drawdown or annuity: the three ways to take pension income →How the 25% tax-free entitlement works differently under UFPLS and flexi-access drawdown, what crystallisation means, the £268,275 lump sum allowance, and where annuities fit: the mechanics behind the choice.
- Sequence-of-returns risk, shown with real market history →Two retirees earn the same average return and one runs out of money: why the order of returns dominates retirement outcomes, which historical cohorts it broke, and how to test a plan against it honestly.
- What a defined benefit pension is actually worth →NHS, teachers, civil service, old company schemes: why £10,000/yr of DB pension is worth more than most people's entire DC pot, how to compare added-pension offers, and why transferring out is almost always wrong.
- What happens to your pension when you die →Nominations and scheme discretion, the age-75 line that decides whether your beneficiaries pay income tax, beneficiary drawdown, what defined benefit schemes pay, and how the April 2027 inheritance tax change rewrites the answer.
How annuities are priced
An annuity is insurance in reverse: you hand an insurer a pension pot and they pay a guaranteed income until you die, however long that is. The rate depends mostly on your age (older buyers get more per pound, because the insurer expects to pay for fewer years), and on gilt yields (what the insurer can safely earn on your money). Every option you add (income continuing to a spouse, a guarantee period, inflation-linking) is paid for out of the starting rate, which is why an index-linked joint-life annuity starts at barely half the level single-life income.
Enhanced annuities pay more if your life expectancy is reduced: smoking, diabetes, heart conditions and many common medications all qualify. Around half of applicants qualify for some enhancement, and it is one of the few times poor health improves a financial quote, so always disclose honestly when getting real quotes.
The certainty trade-off
Once bought, an annuity usually cannot be changed or cashed in, and beyond any guarantee period or spouse provision, nothing passes to your estate. Against that: no investment risk, no running-out risk, and no decisions to make at 90. The full Hundred Summers plan models an annuity, flexible drawdown, or a blend of the two inside your whole lifetime picture, including the tax on the income and what each route leaves behind.
