Case Study: What to Do With a Small DB Pension — Trivial Commutation, Small Pots and When to Transfer (2026 Guide)

If you have a small deferred DB pension, you can't always cash it in. Trivial commutation only works if all your pensions together are worth £30,000 or less, and the small pots rule only covers a pension worth £10,000 or less. If neither applies, the main choices are to keep the pension or transfer it, and in this illustrative example the sensible outcome was simply to keep the guaranteed income.

Quick summary

• Illustrative example: "Susan", 62, a retired primary school teacher
• Issue: a small deferred DB pension from an earlier private sector employer (CETV £28,000). It's too small to live on and feels like an administrative nuisance.
• Options explored: trivial commutation, the small pots rule, transfer to a SIPP, or keep it in the scheme
• Likely outcome: keep the DB pension and take the income from 65, as neither cash-in route is available and the guaranteed income has real value
• Key point: the legal advice requirement doesn't apply when safeguarded benefits are worth £30,000 or less, but the decision still deserves careful thought

Most pension transfer discussions focus on large DB pensions with six-figure Cash Equivalent Transfer Values (CETVs) that trigger the legal requirement for regulated advice. But what about a DB pension that is simply small?

This illustrative example looks at how someone with a small, deferred occupational DB pension might work through their options. Susan is hypothetical and the figures are examples only.

Meet Susan: A Small Deferred DB Pension

Imagine Susan. She is 62 and recently retired after 28 years as a primary school teacher. She already receives her Teachers' Pension Scheme (TPS) benefits, a guaranteed income she relies on. Her State Pension will start at 67.

Before she went into teaching, Susan spent six years working for a private sector company. She built up a small deferred DB pension in that company's scheme, and it has sat untouched for over 25 years.

The details:

• Scheme: a former employer's occupational DB scheme (private sector)
• Deferred pension: £1,050 a year from 65
• Cash Equivalent Transfer Value (CETV): £28,000
• Other pensions: her TPS pension (about £15,500 a year in payment) and a small DC pot of £28,000

Key point: The legal requirement to take regulated advice before transferring applies only where safeguarded benefits (such as a DB pension) are worth more than £30,000. Susan's CETV is below that, so advice isn't legally required. That doesn't mean a transfer is a good idea. It means the decision is hers to make, and free guidance is a sensible first step.

The TPS is an unfunded public sector scheme, so it cannot be transferred to a DC pension in any case. The only pension in play here is the small private sector DB pension.

What Are Susan's Options?

Susan is frustrated. The small pension sends her annual statements she finds hard to follow, and £1,050 a year feels barely worth the paperwork. She has four options in mind:

1. Leave it in the scheme: take the £1,050 a year from 65 and stop worrying about it
2. Transfer to a SIPP: move it into a personal pension for simplicity
3. Trivial commutation: cash in her pension savings as a single lump sum
4. The small pots rule: take the small DB pension as a lump sum under a separate rule

Understanding Trivial Commutation

Trivial commutation is a rule in UK pension tax law that can let you take your pension benefits as a single lump sum, partly tax-free, if the total value of all your pension savings is below a set limit.

Important: the main trivial commutation rules

• You must normally be at least 55 (rising to 57 on 6 April 2028, unless you have a protected pension age)
• The total value of all your pension savings must be no more than £30,000
• That limit is tested across all your pensions, not just the one you want to cash in
• Usually 25% of the lump sum is tax-free and the rest is taxed as income
• All trivial commutation payments must be made within a 12-month period

This is where Susan's situation gets more complicated. Her small DB pension is worth £28,000 on its own, but her total pension savings, including her TPS pension, are worth far more than £30,000.

Why Susan Can't Use Trivial Commutation

Many people assume that because one pension is worth less than £30,000 they can automatically cash it in under trivial commutation. That isn't how it works.

The £30,000 limit applies to the combined value of all your pension savings. HMRC has its own valuation rules for this test, which value a DB pension at a multiple of its yearly amount and a DC pot at its fund value.

For Susan, roughly:

• TPS value: about £310,000 (using £15,500 a year × 20 as a rough illustration)
• DC pension pot: £28,000
• Former employer DB pension: £28,000
• Total: roughly £366,000

Susan's total is many times the £30,000 limit, so trivial commutation isn't available to her.

Key point: Even if one pension is small, trivial commutation needs all your pension savings combined to be £30,000 or less. Most people with a Teachers', NHS or other main DB pension will not qualify.

The Small Pots Rule: A Different Route

There is a separate rule that is often confused with trivial commutation: the small pots rule.

Under this rule, you can cash in a small pension pot worth £10,000 or less as a lump sum, whatever the total value of your other pensions. For personal pensions, you can do this up to three times in your lifetime. Occupational schemes, including DB schemes, have their own version of the rule with different conditions, so check with the scheme.

Trivial commutation and the small pots rule compared

Feature	Trivial commutation	Small pots rule
Limit per pension	No separate limit	£10,000 per pot
Limit on total pension savings	£30,000 in total	No total limit
How often	One 12-month window	Up to three personal pension pots; occupational scheme rules differ
Tax	Usually 25% tax-free, rest taxed as income	Usually 25% tax-free, rest taxed as income
Can a DB pension qualify?	Yes, if total savings are £30,000 or less	Yes, if its value is £10,000 or less and the scheme allows it

Susan's deferred DB pension is worth £28,000, which is well above the £10,000 small pots limit. So she can't use the small pots rule either. MoneyHelper explains both rules.

The Transfer Route

With both cash-in routes ruled out, Susan considers transferring her small DB pension into a personal pension.

Because her CETV is £28,000, she isn't legally required to take regulated advice before transferring. But anyone in her position should understand exactly what they would be giving up.

What Susan Would Give Up by Transferring

• Guaranteed income for life: £1,050 a year from 65, increasing under the scheme rules, regardless of how investment markets perform
• A spouse's pension: in this example, her scheme pays 50% of her pension to her husband if she dies first
• PPF protection: if her former employer became insolvent and the scheme couldn't pay, the Pension Protection Fund would usually pay compensation. For someone below the scheme's normal pension age, that is typically 90% of the pension, with more limited increases.
• Inflation protection: in this example, increases in line with CPI up to a cap

Important: The fact that advice isn't legally required below £30,000 doesn't make a transfer suitable. The benefits given up, particularly the lifelong income and spouse's pension, may be worth a lot compared with the transfer value.

Comparing the Transfer Value With the Income

One way to think about it is to ask how much investment growth the transferred £28,000 would need to provide an income like the one Susan is giving up.

• CETV: £28,000
• Income from 65: £1,050 a year, increasing each year
• Assumption for this example: Susan lives into her late 80s
• Growth needed after charges: roughly 5% a year

Around 5% a year isn't impossible, but Susan already has a substantial guaranteed income from her TPS pension and will have the State Pension. She has little need to take investment risk with this pot. For someone with income security already in place, the extra benefit of moving £28,000 and taking on investment risk is small.

Likely Outcome: Keep the Pension

After working through the options, the sensible outcome in an example like Susan's is often the simplest: keep the small DB pension in the scheme and take the £1,050 a year from 65.

Here's why:

1. She doesn't need the lump sum. Her TPS pension and future State Pension cover her living costs. £28,000 wouldn't transform her finances, but £1,050 a year, guaranteed and increasing for life, has real value.
2. The "hassle" is small. The scheme sends an annual statement and that is about it. No active management is needed. Susan's frustration is really about information she doesn't understand, which the scheme or MoneyHelper can help explain.
3. The PPF safety net is valuable. It gives a level of protection Susan hadn't thought about.
4. The 2027 IHT changes have limited effect here. From 6 April 2027, unused pension funds and most pension death benefits are due to come into the scope of inheritance tax. A DB pension in payment doesn't leave an unspent pot, and dependants' pensions are expected to stay outside IHT, so this change doesn't argue for a transfer.

Lesson from Susan's example: Not every pension question needs a complex answer. For a small DB pension where the guaranteed income is real, keeping the scheme benefit and taking the income is often the most sensible choice, even if it feels untidy.

Factors That Can Change the Picture

For some people, the balance can look different. Each of these needs individual thought, and none of them means a transfer or cash-in is right on its own.

Very poor health. If someone's life expectancy is severely reduced, a guaranteed income may be paid for only a short time. But the scheme may also have ill-health rules that allow earlier, unreduced payment, which should be checked first.

A pension worth £10,000 or less. The small pots rule may allow a cash lump sum if the scheme permits it. Even then, it's worth comparing the lump sum with the income given up.

Concerns about the scheme's finances. If the employer fails, the PPF usually steps in, though compensation can be lower than the full scheme pension. That is rarely a reason to transfer by itself.

Several small pensions starting at different ages. Some people find this genuinely complicated. Often a clear summary of what each scheme pays, and when, solves the problem without a transfer.

No spouse or dependants. A spouse's pension has no value to someone who will never use it. But the lifelong guaranteed income still does.

Even where advice isn't legally required, free guidance helps make sure the decision is properly thought through.

Getting Help With a Small Pension

The legal advice requirement only applies when safeguarded benefits are worth more than £30,000. But the rules on trivial commutation, small pots and tax mean help is still useful for smaller pensions.

MoneyHelper offers free, impartial guidance on pensions, backed by government, and can help you:

• Understand whether trivial commutation or the small pots rule could apply to you
• Understand the benefits you would give up by transferring
• See how a small pension fits into your wider retirement income

If you're 50 or over, you can also book a free Pension Wise appointment about your DC pensions. Be wary of anyone who contacts you out of the blue about your pension or offers to "unlock" it, and check the FCA's ScamSmart pages first.

I don't give pension transfer advice. I offer a free, no-obligation chat about how DB transfers and the advice process work, which is general information, not advice, and I can introduce people who want regulated advice to an FCA-authorised firm that holds the pension transfer permission. Arthur Browns may receive a fee from the firm we introduce you to if you become their client. Introductions are for UK residents with a transfer value of £50,000 or more, so for a pension of Susan's size, MoneyHelper is the best place to start. You can still get in touch if you're unsure where to go.

Five Things Susan's Example Shows

1. Trivial commutation is based on all your pension savings, not one pot. Most people with a main DB pension won't qualify.
2. The small pots rule is separate and helps with truly small pensions, but only for pensions worth £10,000 or less.
3. Below £30,000, regulated advice isn't legally required, but free guidance is still worth having.
4. £1,050 a year, guaranteed and increasing for life, is real money. It's easy to undervalue a small guaranteed income when you focus on the lump sum.
5. DB pensions are less affected by the 2027 IHT changes than unspent DC pots, because a DB income doesn't leave a fund behind. One-off DB lump sum death benefits may still be in scope.

Frequently asked questions

What is trivial commutation and who qualifies?

Trivial commutation lets you take your pension savings as a single lump sum if the total value of all your pensions is £30,000 or less. You must normally be at least 55 (rising to 57 from 6 April 2028, unless you have a protected pension age). The £30,000 limit applies to all your pensions combined, not just one. Most people with a significant main pension, such as a Teachers' or NHS pension, will not qualify.

What is the small pots rule for pensions?

The small pots rule lets you take a pension worth £10,000 or less as a cash lump sum, whatever the total value of your other pensions. For personal pensions you can do this up to three times. Occupational schemes have their own version with different conditions. Usually 25% is tax-free and the rest is taxed as income.

Do I need financial advice to transfer a small DB pension under £30,000?

No. The legal requirement to take regulated advice only applies where your safeguarded benefits are worth more than £30,000. Below that, advice isn't legally required. But transferring a DB pension means giving up valuable guarantees, including lifelong income, inflation protection and a spouse's pension, so free guidance from MoneyHelper is a sensible first step.

Is it worth keeping a small DB pension rather than transferring it?

Often, yes. Even a small guaranteed income, say £1,000 a year, has real lifelong value. Once you take into account inflation increases, a spouse's pension and Pension Protection Fund cover if the employer fails, keeping a small DB pension can be worth more than the cash transfer value suggests.

Will the 2027 pension IHT changes affect my small DB pension?

From 6 April 2027, unused pension funds and most pension death benefits are due to come into the scope of inheritance tax. The change mainly affects DC pots that are left unspent. A DB pension pays an income during your life, and dependants' pensions are expected to stay outside IHT, so the direct effect on most DB members is limited. One-off DB lump sum death benefits are expected to be in scope.
