Defined Benefit Pension and FIRE: Should You Transfer Out?

What Is a Defined Benefit Pension?

A defined benefit (DB) pension — sometimes called a final salary or career average pension — pays you a guaranteed income for life, usually linked to inflation. Unlike a SIPP or workplace defined contribution (DC) scheme, the income does not depend on investment performance. The scheme promises to pay a fixed amount, adjusted each year, for as long as you live.

DB pensions are almost entirely confined to the public sector: NHS, teaching, civil service, police, military, local government, and a handful of large private-sector schemes that closed to new members years ago. If you work — or have ever worked — in any of these, you likely have a DB entitlement even if you left the scheme years ago.

The income from a DB pension is calculated using a formula. A typical public sector scheme might use:

For example: 20 years of NHS service with an accrual rate of 1/54 and a career average salary of £45,000 would give a pension of (20 ÷ 54) × £45,000 = £16,667 per year. That income is guaranteed, inflation-linked, and payable until you die.

How a DB Pension Changes Your FIRE Number

This is the critical insight for FIRE planning: a DB pension directly reduces how much you need to save because it replaces income your portfolio would otherwise need to generate.

Using the 4% rule, every £1,000 per year of guaranteed income is equivalent to having an additional £25,000 in your investment portfolio. A DB pension paying £16,667 per year has the same effect on your FIRE plan as having £416,675 extra in your SIPP — money you never need to save.

Below is a table showing how a DB pension at various income levels reduces the portfolio you need — assuming a target spending of £30,000 per year:

Add the State Pension at 67 (£11,502/year, equivalent to £287,550 in portfolio terms) and many NHS workers, teachers, and civil servants have significantly lower portfolio targets than they realise — even for early retirement. Their DB pension, combined with the State Pension from 67, may cover most or all of their essential spending without drawing a single pound from an ISA or SIPP.

What Is a CETV, and Why Does the Number Feel Tempting?

If you ask your DB scheme to quote your transfer value, they will give you a CETV — Cash Equivalent Transfer Value. This is the lump sum they will pay to a SIPP or other pension if you leave the scheme.

CETVs can look enormous. A DB pension of £10,000 per year might quote a CETV of £280,000–£400,000 depending on your age and prevailing gilt yields. Staring at the prospect of several hundred thousand pounds landing in a SIPP feels compelling compared to a promise of "£10,000 per year from age 60."

But the CETV is what it costs to replicate the same income stream in the open market — and even then, an annuity bought with that CETV would not be inflation-linked, would cease at death (or shortly after), and would not benefit from the Pension Protection Fund (PPF) safety net. The CETV is not "extra money" — it is the fair price for what you are giving up.

When interest rates were very low (2010–2022), CETVs were unusually high relative to the income they replaced. Many people transferred, attracted by eye-catching multiples of 30–40 times annual pension. Subsequent market volatility and rising inflation made many of those decisions look poor in hindsight. The FCA subsequently tightened oversight of DB transfer advice significantly.

The Legal Requirement Before Any Transfer

If your CETV is £30,000 or above — which it almost certainly is if you have any meaningful DB entitlement — you are legally required to take regulated financial advice from a Pension Transfer Specialist before the transfer can proceed. This is not optional and cannot be waived.

This rule exists because the FCA found that the vast majority of DB-to-SIPP transfers were not in the customer's best interests. The advice requirement acts as a gate: an adviser must be willing to recommend the transfer (or indicate it is suitable) before it can happen. Many advisers will not recommend transfers except in clear-cut cases.

The regulated advice itself is not free — expect fees of £3,000–£5,000 or more, sometimes calculated as a percentage of the CETV. Even if you ultimately decide not to transfer, you will likely pay for the advice.

For most FIRE pursuers, the regulated advice process is the right safeguard — not a bureaucratic obstacle. An adviser who declines to recommend a transfer is likely protecting your long-term financial security, even if it is frustrating in the moment.

When Might Transferring a DB Pension Make Sense?

Transferring is rarely the right answer, but a regulated adviser may consider it suitable in specific circumstances:

The critical point: even if one or more of these circumstances applies to you, the decision requires regulated advice. Transfer is irreversible. Once the CETV lands in your SIPP, the guaranteed income is gone permanently.

The Better FIRE Strategy: Using Your DB Pension as an Income Floor

Rather than transferring out, most FIRE pursuers with a DB pension should treat it as the foundation of their retirement income — the guaranteed floor on which everything else sits.

The classic two-phase FIRE structure with a DB pension looks like this:

• Phase 1 (early retirement to DB pension age): Draw on ISAs and SIPPs to cover living costs. Your DB pension is still accruing or deferred, waiting at its normal retirement age.
• Phase 2 (DB pension starts): Your DB income begins, reducing or eliminating ISA/SIPP withdrawals. Your portfolio recovers or grows during this phase.
• Phase 3 (State Pension at 67): State Pension further supplements income. ISA and SIPP withdrawals drop again, and your portfolio can last substantially longer — or be passed on.

One practical note: many DB schemes allow you to draw your pension early with an actuarial reduction. Taking an NHS pension 10 years before its normal retirement date might reduce the annual income by 35–45%. For FIRE purposes, it is usually more efficient to bridge early retirement with ISAs and let the DB pension start on time — or close to it.

The security this structure provides is substantial. Sequence of returns risk — the danger of a market crash in the first years of retirement — is dramatically reduced when guaranteed income already covers a large portion of your spending. You are not forced to sell investments at depressed prices to pay the bills.

Common Mistakes DB Pension Holders Make in FIRE Planning

• Ignoring it in FIRE number calculations. A DB pension from a previous employer may have been deferred for years and easy to forget. Include it in your modelling — it can cut your required portfolio by hundreds of thousands of pounds.
• Treating the CETV as found money. The CETV is what your guaranteed income is worth, not a bonus on top of it. Transferring converts a guaranteed income into an uncertain one.
• Underestimating early-access reductions. If your DB scheme's normal retirement age is 65 and you want to retire at 50, the actuarial reduction is severe. Factor this into your bridging calculations.
• Not checking for additional DB entitlements. If you worked in the NHS, education, or civil service at any point, you likely have a deferred DB entitlement. Track these down via your previous employer's HR team or the pension scheme administrator.
• Forgetting survivor benefits. Most DB schemes pay a reduced pension to a surviving spouse or civil partner. If you transfer out, this benefit disappears. For those with dependants, this is often the single most compelling reason to stay in the scheme.
