Pension Drawdown Rules: How to Take an Income From Your SIPP Without Running Out of Money at 78

The moment you stop paying into a pension and start taking money out of it, the entire game changes. Accumulation is forgiving — you can be sloppy about fund choice, overpay a platform fee for a decade, and still retire with a decent pot simply because time and compounding covered for you. Drawdown offers no such mercy. Get the order of withdrawals wrong, trigger the wrong allowance, or pull too much out in a falling market during your first three years of retirement, and you can permanently cripple a pot that would otherwise have lasted twenty-five years. This is the part of pension planning that gets almost no attention next to the endless content about SIPP charges and fund selection, even though it decides whether the money you spent thirty years building actually lasts as long as you do. Building the pot is the easy half. Spending it without running dry, without handing HMRC more than you need to, and without locking yourself into an annuity at the wrong moment — that's the actual test, and most men reach 55 having never thought about it properly.

Normal Minimum Pension Age: 55 now, 57 from 2028

You can currently access a defined contribution pension, including a SIPP, from age 55. That threshold — the Normal Minimum Pension Age — rises to 57 on 6 April 2028, and there's a protection regime for anyone whose scheme rules specifically guaranteed access at 55 before the change was announced. If you're in your early fifties now and your SIPP doesn't carry that protection, plan around 57 as your real access age, not 55. Providers including AJ Bell and Interactive Investor have already updated their platform guidance to flag this to members turning 53 and 54.

Reaching the access age doesn't mean you should touch the money immediately. Every year you leave a pension untouched past 55 is a year it keeps growing tax-free inside the wrapper, and a year closer to the point where you might actually need the income rather than merely being allowed to take it.

The 25% tax-free lump sum has a hard ceiling now

Since the Lifetime Allowance was scrapped in April 2024, the tax-free element of your pension is governed by the Lump Sum Allowance, set at £268,275. That's 25% of the old £1,073,100 Lifetime Allowance, carried forward as a cash figure rather than a percentage of an abolished cap. If your combined pension pots are worth less than roughly £1.07 million, the practical effect is the same as before: 25% comes out tax-free, the rest is taxable income when you draw it. Above that combined value, the tax-free portion is capped in cash terms regardless of how large the pot grows afterwards.

Most men reading this won't hit that ceiling, but it matters if you've built up a large SIPP alongside a generous final-salary scheme from an earlier employer — the two get added together for this test, not assessed separately.

UFPLS vs flexi-access drawdown — the two ways to actually take the cash

There are two standard routes into your tax-free entitlement, and providers rarely explain the difference clearly enough.

• Flexi-access drawdown: you take the 25% tax-free lump sum up front for the whole pot (or a portion of it) in one go, moving the remaining 75% into a drawdown account that stays invested. You then draw taxable income from that account on whatever schedule suits you.
• UFPLS (Uncrystallised Funds Pension Lump Sum): each withdrawal is automatically 25% tax-free and 75% taxable, taken in that ratio every single time, straight from the uncrystallised pot with no separate drawdown account.
• UFPLS suits someone taking irregular, occasional withdrawals who wants simplicity over control.

Flexi-access is the better choice for anyone planning a structured retirement income, because it lets you take the tax-free cash early — useful for clearing a mortgage or funding a big one-off cost at 57 — while leaving the invested remainder to keep growing untouched for years.

The Money Purchase Annual Allowance: the trap that catches high earners still working

One decision, made once, that you can never undo.

This is the rule that causes the most expensive mistakes, and it's the one nobody explains before you make it. As soon as you draw any taxable income from a pension — not the tax-free lump sum, the taxable slice — your annual pension contribution allowance collapses from the standard £60,000 down to just £10,000. That's the Money Purchase Annual Allowance, and it applies for the rest of your life once triggered, across every pension you hold.

Taking the 25% tax-free lump sum on its own does not trigger the MPAA. Taking even £1 of taxable drawdown income does. This matters enormously for a man in his late fifties who's still working part-time or consulting and wants to keep funding a pension for the tax relief — dip into taxable drawdown too early and you've capped your own contribution room at a sixth of what it was, permanently, for a decision that might have saved you a few hundred pounds in the short term.

If you're still earning and don't strictly need the income yet, take the tax-free cash if you want it, and leave the taxable portion alone until you've actually stopped contributing meaningfully to a pension.

How much can you actually withdraw without running the pot dry?

The "4% rule" gets quoted constantly and it's a reasonable starting point, not gospel. It comes from US research (the Trinity study, based on 1926–1995 market data) testing a 4% initial withdrawal, adjusted for inflation each year, against a 30-year retirement horizon and a 50/50 stock/bond portfolio. For a UK retiree drawing from age 57 rather than 65, that horizon might need to stretch to 35 or 40 years, which pushes the safe starting rate closer to 3.3–3.5%. On a £400,000 SIPP, that's the difference between drawing £16,000 a year at 4% and £13,600 at 3.4% — a real gap when you're budgeting a retirement income against council tax, energy bills, and whatever the state pension is doing that particular year. The rate isn't fixed forever either: most drawdown strategies now use "dynamic" withdrawal rules, cutting the percentage after a bad market year and allowing a bit more after a strong one, rather than locking in a fixed cash figure that ignores what the market just did. Nobody enjoys cutting their own income by 10% after a bad year, but it beats discovering at 78 that the pot is gone.

Sequence-of-returns risk is the specific danger drawdown investors face that accumulation investors never do. A 30% market fall in year one of retirement, while you're simultaneously withdrawing income, does far more permanent damage than the same fall hitting in year fifteen — because you're selling units at depressed prices to fund your lifestyle at exactly the moment the pot can least afford it. Keeping one to two years of income in cash or short-dated gilts inside the SIPP, so you're not forced to sell equities during a downturn, is the standard defence, and it's worth doing even though cash earns nothing like what the invested portion might.

Drawdown income is taxed like a salary — plan the band, not just the amount

Every taxable withdrawal from drawdown gets added to your other income for the tax year and taxed at your marginal rate: 20% between £12,570 and £50,270, 40% up to £125,140, and 45% above that (rates for England, Wales and Northern Ireland; Scotland runs its own bands). This is where a lot of retirement income planning quietly falls apart — a man draws a lump sum to cover a kitchen renovation or a car, and the withdrawal alone tips him from basic rate into higher rate for that entire tax year, on income he didn't even need to take as a single payment.

Spreading large withdrawals across two tax years, taking them in April rather than March where the timing is flexible, and using ISA savings for lumpy one-off costs instead of pension withdrawals are all straightforward ways to keep the marginal rate down. It's worth saying plainly: treating a SIPP like a cash machine for irregular big purchases is the single most avoidable way to overpay tax in retirement, and the fix costs nothing beyond a bit of forward planning with a calendar.

Annuity or drawdown — don't assume flexibility always wins

Annuity rates have recovered sharply since the low-rate years of the 2010s and early 2020s, tracking gilt yields upward. A healthy 65-year-old man can currently secure a single-life, level annuity paying somewhere around 7% of the purchase price annually — meaning a £200,000 pot buys roughly £14,000 a year, guaranteed, for life, with no market risk and no chance of running out. Drawdown can't match that certainty at any withdrawal rate that's actually sustainable.

The honest recommendation for most men is a blend rather than an all-or-nothing choice: annuitise enough of the pot to cover essential fixed costs — the mortgage, council tax, food, utilities — so that a market crash can never touch your ability to pay for the basics, and keep the rest in drawdown for discretionary spending and the growth potential a locked-in annuity can never offer. Going 100% annuity sacrifices the upside and the flexibility that made a SIPP worth building in the first place. Going 100% drawdown at 57 with no guaranteed income floor at all is a bet that thirty-plus years of market returns and disciplined withdrawal behaviour go exactly to plan, and that's a bigger bet than most people going into it realise they're taking.

One more point worth making plainly: Pension Wise, the free government-backed guidance service run through MoneyHelper, gives a genuinely useful hour-long consultation to anyone over 50 with a defined contribution pension, and it's free. It won't recommend specific products, but it will walk through exactly these trade-offs against your own numbers before you commit to anything irreversible — and given that some drawdown decisions can't be undone once taken, that free hour is worth booking before you touch a penny of the pot.
