Pension wealth is more unequally held than any other kind of wealth this site measures
The top tenth of households hold 64% of all private pension wealth. Women approaching retirement hold roughly half what men the same age hold. And the self-employed have been left almost entirely outside the system that transformed employee saving.
Three separate, independently verified inequalities sit inside "pension wealth", each measured by a different official source. Private pension wealth is more concentrated at the top than total household wealth — ONS's own finding, not an inference. The gender pension gap is 48% among people aged 55–59 with private pension wealth. This accumulated wealth measure is distinct from the annual pay gap. IFS finds pension participation among self-employed people with profits above £10,000 fell from 60% in 1998 to around 20% by the early 2010s. This timing does not establish an effect of automatic enrolment.
Read this first — what else changes the meaning of the headline
- Top decile share of all private pension wealth
- 64%
April 2018 to March 2020 — the bottom five deciles combined hold under 1%. ONS's own words: more unequal than total household wealth.
ONS, Pension wealth in Great Britain: April 2018 to March 2020
- Gender pension gap, age 55-59
- 48%
£81,000 (women) vs £156,000 (men), 2020 to 2022. Rises to 62% including people with no pension wealth at all.
- Self-employed contributing to a pension
- ~20%
Since around 2013 — down from 60% in 1998. Auto-enrolment does not apply to the self-employed at all.

ONS states directly: "there is more inequality in private (non-state) pension wealth than total net wealth" — private pension wealth is a narrower and even more concentrated slice than the total household wealth figures used elsewhere on this site.
| Wealth decile | Median private pension wealth |
|---|---|
| Decile 1 (poorest) | £0 |
| Decile 2 (poorest) | £0 |
| Decile 3 (poorest) | £0 |
| Decile 4 | £1,200 |
| Decile 5 | £7,800 |
| Top decile (10th) | £637,500 |
The bottom three deciles have a median private pension wealth of £0 — not a small amount, no private pension at all. The gap between decile 4 (£1,200) and the top decile (£637,500) is over 500-fold.
Vintage note. This decile breakdown is from ONS’s dedicated pension-wealth bulletin, April 2018 to March 2020 — older than the 2020–2022 total-wealth figures used elsewhere on this site, because ONS has not published an equivalent pension-specific decile breakdown since. The Office for Statistics Regulation suspended the Wealth and Assets Survey’s accredited status on 13 June 2025, and it has not been restored — see the wealth & tax page for the full disclosure, which applies equally to the figures on this page.
DWP has published an official measure of this gap since 2023 — The difference between female and male median uncrystallised private pension wealth — pension savings not yet drawn.
The headline 48% figure excludes people with zero private pension wealth entirely. Once they are included, the gap widens to 62% — because more women than men have no private pension wealth at all, not only smaller amounts among those who do.
Pension wealth accumulates over a working life; the full-time hourly pay gap measures a different population and period. These percentages cannot identify how much of the wealth gap is caused by pay, career breaks or part-time work. DWP warns that the 2020–2022 pension estimates are not comparable with earlier releases because defined-benefit valuation changed. Pandemic telephone collection and survey representativeness also add uncertainty.
Automatic enrolment applies only to employees — the self-employed were deliberately excluded from the policy that took eligible employees’ participation from 55% to 90%, and no equivalent mechanism has been introduced for them.
This figure is repeated consistently across several IFS publications on self-employment and pensions. Attributed to IFS's own analysis, not independently re-derived by this site.
What this page cannot tell you
Real limits on what these three inequality measures can establish:
How much of the gender pension gap comes from pay versus career breaks versus part-time work
Whether the self-employed pension figures reflect a genuine savings gap or other retirement provision
What it means
- What the data directly shows
- Private pension wealth is held even more unequally than total household wealth; women aged 55-59 hold roughly half the private pension wealth men the same age hold; and pension participation among self-employed people with profits above £10,000 fell from 60% in 1998 to around 20% by the early 2010s.
- What can reasonably be inferred
- Pension wealth compounds inequalities that exist earlier in working life (pay, career continuity, employment status) rather than creating new ones from nothing — a lifetime of smaller gaps produces a much larger gap by retirement.
- What is disputed
- Whether extending an auto-enrolment-style mechanism to the self-employed is practical, given the absence of a single 'employer' to make matching contributions, is a genuinely difficult design question, not just a political one.
- A political judgement, not a finding
- What (if anything) to do specifically about the gender pension gap or self-employed pension gap — beyond the general policy options already covered on the workplace-pensions page — is a live and contested policy area this site does not take a position on.
- What the evidence cannot establish
- How today's 55-59 gender pension gap will look for younger cohorts once auto-enrolment (introduced in 2012) has had a full working lifetime to take effect — no data yet exists to answer that.
