Phased retirement in the UK: how to ease into retirement without wrecking your pension

Retirement used to be a cliff edge. For a growing number of people it's now a slope — fewer days, less responsibility, and a pension topping up the gap. Here's exactly how it works, what you're legally entitled to ask for, and the one mistake that costs people the most.

What phased retirement actually means

Phased retirement is the practice of winding down gradually — reducing your hours, your days, or your level of responsibility over several years — rather than working full-time on the Friday and being fully retired on the Monday.

The important thing to understand up front is that it isn't a single legal scheme you apply to. It's two separate decisions that you make at roughly the same time:

1. A change to your working pattern — fewer days, shorter days, a job share, or a step down from a management role. This is an employment matter, governed by your contract and by the statutory right to request flexible working.
2. A decision about your pension — whether to start drawing some of it now to top up your reduced pay, and if so, how much and from where. This is governed by tax law and by your scheme's own rules.

Why it's suddenly on everyone's mind

Two things have converged.

The first is demand. In its 2024 Global Benefits Attitudes Survey of 6,000 UK employees, WTW found that nearly half of workers aged 50 and over had either already begun phasing into retirement or wanted to. Of those already doing it, three-quarters had done it by reducing their hours. And this isn't a short goodbye: those who started phasing at 56 expected to work another ten years.

The second is arithmetic. State Pension age is rising from 66 to 67 right now — the change is being phased in between April 2026 and April 2028. If you were born between 6 April 1960 and 5 March 1961, your State Pension age is somewhere between 66 years and one month and 66 years and eleven months. Born on or after 6 March 1961, it's 67.

That creates a gap for a lot of people between the point at which full-time work stops being appealing or manageable, and the point at which the State Pension arrives. Phased retirement is, for many, simply the most practical way to bridge it.

Phased retirement isn't about doing less. It's about deciding, deliberately, what the last stretch of your working life looks like — rather than having it decided for you.

Your legal position: what you can ask for

Let's be precise, because this is widely misunderstood.

There is no automatic right to phased retirement in the UK. Your employer isn't obliged to agree to it unless your contract or a workplace policy says so.

But there is a statutory right to request flexible working, and it's stronger than most people realise. Since 6 April 2024 it has been a day-one right — no qualifying period of service. Under Part VIIIA of the Employment Rights Act 1996, as amended:

• You can make two statutory requests in any 12-month period (though only one can be live at a time).
• Your employer must give you a decision, including any appeal, within two months of receiving the request, unless you both agree to extend it.
• Your employer must consult you before refusing.
• They can only refuse for one of eight statutory business reasons — such as the burden of additional costs, a detrimental effect on quality or performance, or an inability to reorganise work among existing staff. "We've never done that here" is not on the list.
• If your request is accepted, your contract must be updated within 28 days.
• If your employer misses the two-month deadline, refuses on a reason that isn't one of the eight, or bases the refusal on incorrect facts, you can take the matter to an employment tribunal. Acas has a statutory Code of Practice on this which tribunals must take into account.

Worth knowing

The Employment Rights Act 2025 is expected to tighten this further from 2027, requiring employers not just to cite one of the eight reasons but to explain why refusing on that basis was reasonable. That shifts the question from "can we refuse?" to "can we justify refusing this particular request?" — a meaningful change if you're planning a conversation a year or two out.

The three pension rules that matter most

1. You generally can't touch a private pension before 55

The normal minimum pension age in the UK is 55, rising to 57 on 6 April 2028. Individual schemes can and do set additional conditions on top of that. Your State Pension is entirely separate and comes at State Pension age.

2. The Money Purchase Annual Allowance is the trap

This is the single most expensive mistake in phased retirement, and it's almost entirely avoidable if you know about it in advance.

Normally you can pay up to £60,000 a year into pensions with tax relief. But the moment you take taxable income from a defined contribution pension, you trigger the Money Purchase Annual Allowance (MPAA) — and your DC contribution limit drops to £10,000 a year, permanently. It cannot be reversed, and you can't use carry-forward to get around it.

The crucial detail: taking only your 25% tax-free cash does not trigger it.

Two ways to take money from a DC pension — very different consequences

If you plan to keep working and keep contributing, this distinction is worth real money

Sources: GOV.UK — Tax on your private pension contributions and MoneyHelper. Defined benefit pensions are treated differently — drawing a DB pension does not itself trigger the MPAA.

So if you're going part-time at 58 and still want to pay meaningfully into a pension for another decade, the sequencing matters enormously. Taking tax-free cash to bridge the income gap keeps your options open. Turning on drawdown income closes them.

3. Tax-free cash has a ceiling

You can normally take 25% of a pension pot tax-free, but there is an overall cap: the Lump Sum Allowance of £268,275 across all your pensions. Once you've had that much tax-free cash in total, further lump sums are taxed as income — even if 25% of the remaining pot would be more.

NHS, Teachers' and LGPS: how each scheme handles it

If you work in the public sector, you may have a formal partial retirement route built into your scheme — and the rules are specific. These three cover a very large share of the UK workforce, and they're not interchangeable.

A note on scale: NHS Employers guidance indicates more than 30,000 NHS staff accessed partial retirement in the first period after it was introduced in October 2023, most of them by moving from full-time to part-time hours. If your manager tells you it's unusual, it isn't.

Taking benefits before your scheme's normal pension age will usually mean an actuarial reduction — a permanently lower annual pension, because it's being paid for more years. That's not a penalty, it's arithmetic, but you need to see the numbers before you commit. Every one of these schemes provides an estimate or calculator; ask for one.

The tax picture, with a worked example

Three facts do most of the work here.

The personal allowance is £12,570 and is frozen. The full new State Pension is £241.30 a week in 2026/27 — £12,548 a year, which sits just £22 below that allowance. And you stop paying employee National Insurance at State Pension age, even if you keep working, which is an immediate uplift in take-home pay on the same earnings. Your employer keeps paying theirs. You may need to show proof of age so the deductions stop on time.

Put those together and the shape of a tax-efficient phased retirement becomes clear: spread taxable income across more tax years rather than concentrating it, and use each year's personal allowance and basic-rate band rather than pushing a large sum into one year.

One more lever worth knowing about: if you carry on working past State Pension age, you can defer claiming your State Pension. Under the new State Pension rules it increases by 1% for every nine weeks you defer — just under 5.8% for a full year, for life. That can be attractive if your earnings would otherwise push that income into a higher tax band, though whether it pays off overall depends on how long you live and on your wider circumstances.

Five mistakes that cost people money

1. Triggering the MPAA by accidentTaking a small taxable withdrawal "just to see how it works" permanently caps your DC contributions at £10,000 a year. If you intend to keep saving, take tax-free cash only.
2. Not checking the effect on death benefits and life coverSome schemes calculate death-in-service benefits as a multiple of salary. Halving your hours can halve that cover. Ask before you sign.
3. Overlooking the redundancy calculationStatutory and contractual redundancy pay is usually based on your current earnings. Reducing your hours can reduce a future payout — and in the NHS, taking partial retirement affects contractual redundancy entitlement specifically.
4. Assuming a verbal agreement is enoughGet the new arrangement in writing, as a contractual variation. Public-sector partial retirement routes actually require a documented change to your terms and conditions — a friendly understanding with your line manager won't satisfy the scheme.
5. Drawing more than you need, too earlyMoney left invested keeps working. Drawing heavily in the first years of a phased retirement — especially if markets fall — leaves less to carry you through the decades that follow.

Get free, impartial help before you decide

This is a guide, not financial advice, and everyone's position differs. Two free UK services are genuinely worth using:

• Pension Wise — free, impartial, government-backed guidance appointments for anyone aged 50 or over with a defined contribution pension.
• MoneyHelper — free guidance on pensions, tax and benefits, backed by government.

For decisions involving a defined benefit pension worth more than £30,000, regulated financial advice is a legal requirement, not just a good idea.

How to actually ask your employer

The request itself is straightforward. Making it persuasive is the part worth thinking about.

One further thought. If your employer says no, or the role simply doesn't lend itself to three days a week, that isn't the end of the phased retirement idea — it's just the end of doing it in that job. Plenty of people phase down by moving employers: leaving a demanding full-time role for a part-time one elsewhere, often in a sector with more flexibility built in. That's not a step backwards. It's the same strategy with a different address.
