When the time comes to draw money from a defined contribution pension, SIPP, or group personal pension flexibly, there are two principal methods: flexi-access drawdown (FAD) and uncrystallised fund pension lump sums (UFPLS). Both were introduced or clarified by the pension freedoms reforms of 2015, and both give you flexible access to your pension savings — but they operate differently and suit different situations.
Understanding the mechanics of each helps you choose the method — or combination of methods — that maximises tax efficiency and suits your retirement income needs.
Flexi-Access Drawdown (FAD)
How It Works
With flexi-access drawdown, you designate all or part of your pension fund to a drawdown arrangement. At the point of designation, you have a one-time opportunity to take a pension commencement lump sum (PCLS) — the 25% tax-free cash payment.
The mechanics:
- You notify the pension provider you wish to enter drawdown.
- Up to 25% of the fund value designated to drawdown is paid to you as a PCLS, free of income tax.
- The remaining 75% remains invested in the drawdown fund.
- You can then draw income from the drawdown fund at whatever level and frequency you choose.
- Each income withdrawal from the drawdown fund is taxable as income at your marginal rate.
Importantly, once the fund is designated to drawdown, the PCLS opportunity for that portion of the fund is used. You cannot take a further PCLS from funds already crystallised into drawdown.
The Lump Sum Allowance Cap
Tax-free cash under the drawdown route is governed by the Lump Sum Allowance (LSA) of £268,275. The Pension Commencement Lump Sum (PCLS) is limited to the lower of 25% of the fund and £268,275 — the maximum PCLS under current rules (as of 2026, following the abolition of the lifetime allowance on 6 April 2024).
Where a fund is large enough that 25% would exceed £268,275 (broadly, fund value above £1,073,100), the tax-free cash is capped at the LSA. If your pension pot is £600,000, your maximum PCLS is £150,000 (25%). If your pension is £2 million, your PCLS is still capped at £268,275, not £500,000.
When FAD Makes Sense
- When you want to take the maximum available tax-free cash upfront. For larger funds, crystallising early locks in the PCLS before the allowance is eroded by a future rule change or by fund growth.
- When you want a regular, structured income from a defined drawdown pot — leaving the remainder invested.
- When you want to separate the management of your crystallised (taxable) and uncrystallised funds — useful for income planning.
- When the full 25% PCLS is a specific planning goal — for example, to repay a mortgage or fund a particular purchase.
Uncrystallised Fund Pension Lump Sum (UFPLS)
How It Works
A UFPLS is a lump sum payment taken directly from an uncrystallised pension fund — one that has not yet been designated to drawdown or used to purchase an annuity.
The mechanics:
- You request a UFPLS payment from your pension provider.
- The payment is 25% tax-free and 75% taxable as income, automatically, with no need to designate funds to drawdown first.
- The pension pot remains uncrystallised — only the amount of the specific payment is treated as crystallised benefits at the time of withdrawal.
- You can take UFPLS payments as often as you like, in whatever amounts you choose.
The defining feature of UFPLS is that there is no requirement to crystallise the whole fund at once. You take money as and when you need it, with the tax-free element embedded in each payment.
The PCLS Comparison
With UFPLS, each payment carries a 25% tax-free element. Over multiple payments, you spread your tax-free allowance across the lifetime of the fund rather than taking it all at the start.
With FAD, you take all the available tax-free cash upfront as a PCLS.
For a £200,000 fund:
- FAD approach: take £50,000 PCLS tax-free upfront; remaining £150,000 in drawdown, all taxable on withdrawal.
- UFPLS approach: each payment is 25% tax-free. Take £20,000 per year — £5,000 tax-free, £15,000 taxable.
For a £1,200,000 fund where the PCLS cap bites:
- FAD approach: take £268,275 PCLS (the maximum cap). Remaining £931,725 in drawdown, all taxable.
- UFPLS approach: technically 25% of each payment is tax-free, but the total tax-free element across all UFPLS payments is still limited to £268,275 by the Lump Sum Allowance (LSA). Once this is used up, all UFPLS payments become fully taxable.
The MPAA Trigger: A Critical Consideration
Both FAD income and UFPLS payments trigger the Money Purchase Annual Allowance (MPAA) of £10,000.
The MPAA restricts future pension contributions to money purchase (DC) schemes. Once triggered, you can only make £10,000 per year of pension inputs to DC arrangements and receive tax relief on that amount. You retain the full standard annual allowance (£60,000) for DB scheme accrual, but the DC component is severely curtailed.
The MPAA is triggered by:
- Taking your first taxable flexible income from a drawdown fund.
- Receiving a UFPLS payment.
The MPAA is not triggered by:
- Taking a PCLS alone (without starting drawdown income at the same time).
- Purchasing a lifetime annuity.
- Receiving scheme pension from a DB arrangement.
Practical implication: if you are still working and making pension contributions — or intend to return to work and make contributions in future — triggering drawdown or taking a UFPLS reduces your future pension savings capacity dramatically. This is particularly important for those considering early drawdown in their 50s who may continue working for several more years.
For those planning to make significant pension contributions in future years, it may be worth deferring any flexible drawdown until those contributions are complete, to avoid triggering the MPAA prematurely.
When UFPLS Makes More Sense
- You only need a small amount. If you want £20,000 for a specific purpose but your pension is £300,000, a UFPLS avoids crystallising the whole fund — you leave the remaining £280,000 uncrystallised, preserving maximum flexibility.
- You are in a low-income year. A UFPLS taken in a year when your income is low (perhaps between jobs, or in a year of low earnings) can be highly tax-efficient — the 75% taxable element falls within the basic rate band or personal allowance.
- You want flexibility without commitment. UFPLS payments have no minimum and no requirement to maintain regular withdrawals. Take one payment this year and none for the next three years if you choose.
- You have not yet decided your long-term income strategy. UFPLS allows you to draw funds without locking into a drawdown arrangement — useful if you are still working out the best approach.
When FAD Makes More Sense
- You want the maximum tax-free cash upfront. Taking the PCLS now may be prudent if the fund will grow significantly, since the PCLS cap is based on fund value at the point of crystallisation.
- You want regular drawdown income. A structured drawdown arrangement with regular income works more cleanly through FAD — the provider sets up a drawdown plan and pays regular instalments.
- You have a large fund where PCLS timing matters. If your fund is already near the £268,275 PCLS cap, taking it now crystallises that headroom before further growth makes it unavailable.
- You want clear separation between crystallised and uncrystallised pots for income planning and tax management purposes.
Combining Both Methods
There is no requirement to choose exclusively. Many individuals use a combination:
- Take a UFPLS for immediate needs in early retirement while leaving most of the fund uncrystallised.
- Later, when income needs become more regular, crystallise the remaining pot into FAD and take the PCLS at that stage.
- Use multiple smaller UFPLS payments to manage taxable income in any given year, alongside a defined drawdown income stream.
The interaction between UFPLS payments and the PCLS cap requires careful tracking — your total tax-free cash across UFPLS payments and PCLS drawdown designations is limited to £268,275 lifetime.

Frequently asked questions
4 questions
What is the main difference between flexi-access drawdown and UFPLS?
With flexi-access drawdown, you designate funds to drawdown and take 25% as a tax-free pension commencement lump sum upfront. Subsequent withdrawals are fully taxable. With UFPLS, each withdrawal is automatically 25% tax-free and 75% taxable — there is no upfront crystallisation of the whole fund.
Link to this questionDoes taking a UFPLS or starting drawdown trigger the Money Purchase Annual Allowance?
Yes. Both flexi-access drawdown income and UFPLS trigger the Money Purchase Annual Allowance (MPAA) of £10,000. Once triggered, you can only contribute £10,000 per year to money purchase pension schemes with tax relief. The MPAA does not affect contributions to defined benefit schemes.
Link to this questionCan I take my full 25% tax-free cash using UFPLS?
Not in one go, if the total tax-free cash would exceed the £268,275 Lump Sum Allowance (LSA) cap. With UFPLS, each payment is 25% tax-free. If you have a large fund, using drawdown and taking the maximum PCLS upfront may be more efficient than parcelling it through UFPLS over time.
Link to this questionWhat is an uncrystallised fund?
An uncrystallised fund is a pension pot from which no benefits have yet been taken. UFPLS payments can be made directly from uncrystallised funds — you do not need to designate the whole pot to drawdown first. Once any part of the fund is crystallised (into drawdown, annuity, or UFPLS), that portion is treated as crystallised benefits.
