Can you retire early on a — defined benefit pension?
Defined benefit (DB) pensions offer guaranteed income for life. Drawing early is possible, but the actuarial reduction is permanent and larger than most members expect.
- ▸Most DB schemes allow early retirement from age 55 (57 from 2028), but apply an actuarial reduction — typically 3–5% per year of early access.
- ▸Retiring 5 years early on a DB pension worth £20,000 per year at normal retirement age might reduce the annual income to £14,000–£16,000 — permanently.
- ▸Phased retirement (drawing a partial pension while continuing to work reduced hours) is available in many public sector schemes.
- ▸Using DC savings or ISA funds to bridge the gap to normal retirement age — drawing DB unreduced — can be more efficient than taking the early reduction.
How actuarial reduction works on DB
A defined benefit pension promises a specific annual income at the scheme's normal pension age (NPA). If a member draws the pension before NPA, the scheme reduces the annual amount to reflect the longer expected payment period. This is the actuarial reduction.
The logic is straightforward: if the scheme expects to pay a pension for 20 years starting at 65, and you start drawing at 60, it now expects to pay for 25 years. The annual amount must fall so the total expected payout remains broadly the same.
Reduction rates vary by scheme, but a common range is 3–5% per year of early retirement. This means retiring 5 years early reduces the pension by 15–25%. Crucially, this reduction is permanent — it applies for life, not just until NPA. The pension never "catches up" to the unreduced amount.
Some schemes apply different reduction factors depending on age. The reduction for retiring at 55 may be steeper (per year) than for retiring at 60, reflecting the greater actuarial cost of a very early start.
The cost of retiring 5 years early: worked example
Consider a member of the NHS Pension Scheme (2015 section) with a pension of £20,000 per year at their normal pension age of 67.
The NHS scheme applies early retirement reductions based on actuarial factors. Retiring at 62 — 5 years early — the reduction is approximately 20–25% across the full pension. The reduced pension would be roughly £15,000–£16,000 per year.
Over a 25-year retirement (to age 87), the cumulative difference between £20,000 and £15,500 is £112,500. That is the cost of early access — not a fee, but income foregone.
The calculation becomes more nuanced if part of the pension was built up under different scheme sections (e.g., the 1995 or 2008 NHS sections, which have different NPAs and reduction factors). The NHS pension calculator, teachers' pension calculator, and LGPS calculator model scheme-specific reductions.
Phased retirement: drawing and working
Many public sector DB schemes offer phased retirement — the ability to draw part of the pension while continuing to work, often on reduced hours. This provides income supplementation without triggering the full actuarial reduction on the entire pension.
In the NHS, for example, a member can apply for partial retirement (sometimes called "draw down and continue" or "retire and return"), taking a portion of their accrued pension while continuing to build up further benefits on their remaining service. The pension drawn is reduced for early access, but only on the portion taken — the rest continues to accrue at the unreduced rate.
The Teachers' Pension Scheme and LGPS have similar (though not identical) phased retirement provisions. Each scheme sets its own rules about how many times phased retirement can be used, minimum service reductions, and employer agreement requirements.
Phased retirement suits people who want to reduce work intensity gradually rather than stopping abruptly. It can be particularly effective in the final 3–5 years before NPA, when the actuarial reduction on the drawn portion is relatively small.
Using DC savings to bridge to DB
An alternative to accepting the actuarial reduction is to leave the DB pension untouched until NPA and fund the early years from defined contribution (DC) savings — a SIPP, workplace DC pension, or ISA.
The calculation compares two scenarios:
Option A: Draw DB early with a 20% reduction (£16,000 instead of £20,000 per year, permanently).
Option B: Live on DC savings / ISA for 5 years, then draw DB unreduced (£20,000 per year for life).
In Option B, the 5-year bridge costs roughly £80,000–£100,000 from DC/ISA savings (depending on spending level and any investment returns on the bridge pot). But the DB pension is £4,000 per year higher for the rest of the member's life. Over 20 years of retirement after NPA, that is £80,000 of additional income — broadly breaking even after about 20 years and providing a net benefit for anyone who lives longer.
The bridging pension calculator models this comparison, taking into account investment returns on the bridge pot, the specific reduction factors, and life expectancy assumptions.
The decision depends on: the size of the actuarial reduction, the available DC/ISA savings, expected longevity, and whether the member has other income sources (such as a partner's earnings) during the bridge period.

- •Actuarial reduction factors are scheme-specific and can change. Check your scheme's current factors before making decisions.
- •Transferring a DB pension to a DC arrangement to access it differently requires regulated financial advice for pots with a transfer value above £30,000.
- •Phased retirement availability depends on employer agreement — it is not an automatic right in most schemes.
