This page is general information about the NHS Pension Scheme. It is not financial advice — opting out has permanent consequences. Take independent financial advice before deciding. See our disclaimer.

What you actually save: the net figure

Pension contributions attract tax relief, so the take-home gain from opting out is smaller than the gross contribution. For a basic-rate taxpayer, each £1 of contribution costs about 80p net (68p for higher-rate taxpayers, roughly):

Contribution tiers shown use 2025/26 official thresholds (£27,798–£33,868 → 8.3%; £33,869–£50,845 → 9.8%); 2026/27 thresholds are provisional. The net gain is what lands in your pocket — roughly £2,100 a year for a Band 5.

What you lose: the full inventory

• Employer contribution: 23.7% — on £32,073, that's ~£7,601 a year of pension funding you simply don't get.
• Pension accrual: 1/54th of pensionable pay per year — £594/year of annual pension for each opted-out year at Band 5 entry, payable for life from retirement.
• Death-in-service lump sum: 2× pensionable pay (~£64,146 for Band 5 entry) — gone while opted out (see death in service).
• Survivor pensions for spouse/partner and children.
• Ill-health retirement benefits — potentially the most valuable insurance in the package.
• Inflation-proofing: accrued benefits are revalued; opted-out years build nothing.

You keep benefits already built up — opting out stops future accrual, it doesn't confiscate the past.

The £1 vs £3 ratio

Put the two sides together for a Band 5 on £32,073:

• You gain: ~£2,136/year net take-home.
• You give up: ~£7,601/year employer funding + £594/year of lifetime annual pension + ~£64,146 of life cover + ill-health insurance.

Roughly £3–£4 of value foregone for every £1 gained — and the foregone value compounds, because each opted-out year is a year of pension that will never exist. To replicate the lost pension privately would cost far more than the contribution saved.

Worked example: Band 5, one year opted out

A Band 5 nurse (£32,073) opts out for one year at age 30, rejoining at 31:

One "cheap" year costs roughly £11,880 of lifetime pension income (before inflation-proofing) plus a year without life cover — for £2,136 in the pocket. The maths gets worse the longer you stay out.

The narrow exceptions

Opting out can make sense in specific circumstances — all of which warrant professional advice:

• Annual/lifetime allowance pressure: very high earners for whom extra accrual triggers tax charges exceeding the benefit (see annual allowance).
• Very short expected service with no intention to return to the NHS — though even then, a few months' accrual and death cover usually win.
• Genuine affordability crisis: if the choice is the pension or rent, short-term opt-out with prompt rejoining is rational — but treat it as emergency borrowing from your future self, and rejoin fast.

Rejoining and auto-re-enrolment

You can opt back in at any time — contact payroll or use ESR. And under auto-enrolment law, your employer must re-enrol you roughly every 3 years if you're eligible, so staying opted out requires repeated action. But rejoining doesn't restore the gap: the pension you didn't build stays unbuilt.

Alternatives to opting out

• Stay in and budget around it: the contribution is the price of the best-value benefit in your package (see staff benefits ranked).
• Reduce elsewhere first: salary-sacrifice schemes, bank-shift income and budgeting usually free up more than the net contribution.
• Take advice, not action: a single session with an FCA-regulated adviser (or free guidance from MoneyHelper) before opting out.

Opting out to clear debt: the break-even test

The most sympathetic case for opting out is expensive debt: "I'll opt out for two years, clear the credit cards, then rejoin." Test it honestly. A Band 5 opting out frees roughly £178/month net — about £4,272 over two years toward debt. The cost: ~£1,188 of lifetime annual pension not built, ~£15,200 of employer funding foregone, and two years without death-in-service cover. Clearing £4,272 of 25%-APR debt saves well over £1,000 in interest — real money. But the pension given up is worth many multiples of that across a retirement. The rational order of operations: cut spending first, add bank-shift income second, use free debt advice (StepChange, Citizens Advice) third — and treat pension opt-out as the last resort, for the shortest possible period, with the rejoining date already in your diary before you leave.

Two nurses, ten years: the comparison

Two Band 5 nurses, both starting on £32,073. One stays in the scheme for 10 years; the other opts out for the full decade. Illustrative — pay held constant for simplicity:

The opted-out nurse is ~£21,000 richer in cash — and ~£5,940 a year poorer for every year of retirement: roughly £119,000 over a 20-year retirement, before inflation-proofing. There is no way to buy that pension back later at anything like the price the scheme was offering. This is the maths to show anyone — including yourself — who frames opting out as "saving money".

What opting out doesn't affect

Opting out touches only the pension — your other NHS employment rights are untouched:

• Salary and pay progression — identical whether you're in the scheme or not.
• Occupational sick pay — eligibility and entitlement are unchanged.
• Annual leave and bank holidays — unaffected.
• Occupational maternity, paternity and adoption pay — based on service, not pension membership.
• Redundancy terms — calculated on service and pay, not scheme membership.

What is lost is everything the scheme itself provides: the 1/54th accrual, the 23.7% employer funding, the 2× death-in-service lump sum, survivor pensions and ill-health retirement terms (see what you lose). Keep this boundary clear when weighing the decision — opting out doesn't make the job worse, it just deletes one of the best parts of the total package.

Frequently asked questions

Can I opt out of the NHS pension?

Yes — membership is voluntary and you can opt out at any time, usually via your employer's payroll or ESR. But you are automatically re-enrolled every 3 years under auto-enrolment rules.

How much do I save by opting out of the NHS pension?

Your employee contribution — e.g. 8.3% of pensionable pay for most Band 5 staff, about £222 a month on £32,073. But you also give up the 23.7% employer contribution, death-in-service cover and ill-health benefits.

Is it worth opting out of the NHS pension?

Almost never for the contributions alone: you give up roughly £3 of employer funding and benefits for every £1 of employee contribution saved. The exceptions are narrow — e.g. breaching lifetime/annual allowance limits or very short expected service.

What do I lose if I opt out of the NHS pension?

The 23.7% employer contribution, death-in-service lump sum (2× pay), survivor pensions, ill-health retirement benefits, and future accrual at 1/54th per year. You keep benefits already built up.

Can I rejoin the NHS pension after opting out?

Yes — you can opt back in at any time, and auto-enrolment will re-enrol you roughly every 3 years anyway. But the pension you didn't build during the gap is gone for good.

Does opting out affect my take-home pay much?

Less than people expect: pension contributions get tax relief, so the net take-home gain is only about 68–80% of the gross contribution. A Band 5 opting out gains roughly £150–£180 a month net.
