What the official data says at 45
The most reliable picture of British wealth comes from the ONS Wealth and Assets Survey (April 2020 to March 2022 round). For households whose head is aged 45 to 54 — the band that covers age 45 — the median household net worth is £301,900. That is above the median for all GB households (£293,700) and 60% of the peak-age band, 65 to 74, at £502,500.
Two caveats before you compare yourself. These are household figures — couples pool assets, so a single person should expect a lower number. And the ONS has suspended accreditation of this survey from the 2020–22 round while it works on response-rate quality, so treat the figures as the best available official estimate rather than gospel.
| Age of household head | Median household net worth |
|---|---|
| 16 to 24 | £15,200 |
| 25 to 34 | £109,800 |
| 35 to 44 | £209,600 |
| 45 to 54 | £301,900 |
| 55 to 64 | £496,500 |
| 65 to 74 | £502,500 |

Peak earning years begin at 45
At 45 the ONS band moves up again: median household net worth for 45 to 54 households is £301,900 — slightly above the all-ages GB median of £293,700, meaning the typical mid-forties household has just overtaken the typical British household overall. Earnings usually peak somewhere in this band, which makes it the highest-leverage decade for closing any pension gap.
Two levers matter most here. First, unused pension annual allowance from the previous three tax years can be carried forward, letting a big bonus or windfall go into the pension in one move. Second, marginal rates reward it: a 45-year-old on £60,000 faces a 42% marginal rate, so pension contributions effectively buy assets at a 42% discount. The gap between this band's median and the next (£496,500 for 55 to 64) is £194,600 — most of it built in exactly these years.
Median vs mean: why "average" is slippery
Every figure on this page is a median — the middle household if you line everyone up. The ONS uses the median as its headline measure precisely because wealth is so heavily right-skewed: a small number of very wealthy households drag the mean far above the median, so mean ("average") figures quoted in the press can be double the median or more. The ONS publishes mean estimates in its downloadable datasets, but if you want to know what the typical household at 45 has, the median is the honest number.
What counts as net worth
The ONS definition is total household wealth minus debts, built from four components: net property wealth (your home's value minus the mortgage — 40% of all GB household wealth), private pension wealth (35%), net financial wealth (savings and investments minus loans and card debt — 14%) and physical wealth (cars, contents and other possessions — 10%). Note how dominant pensions and property are: most British wealth is not money you can spend this month.
Growing your net worth at 45
If a pension gap exists at 45, carry-forward is the repair tool — up to three previous years of unused annual allowance can be used once current-year allowance is exhausted. And if earnings are approaching £100,000, beware the personal-allowance taper: between £100,000 and £125,140 the effective marginal rate hits 62%, which makes pension contributions in that zone extraordinarily effective. Benchmark your pay at average salary at 45.
Frequently asked questions
What is the average net worth at 45 in the UK?
The ONS Wealth and Assets Survey (April 2020 to March 2022) puts median household net worth at £301,900 for households whose head is aged 45 to 54 — the band covering age 45. The median across all GB households is £293,700. These are household figures, not per person, and include pensions and property.
Does net worth include pensions and property?
Yes. The ONS measure counts net property wealth (40% of GB household wealth), private pension wealth (35%), net financial wealth (14%) and physical wealth (10%), minus debts such as mortgages and loans.
Why is the mean net worth higher than the median?
Wealth is heavily right-skewed: a small number of very wealthy households pull the mean far above the median. The ONS uses the median as its headline measure because it describes the typical household; 'average' figures quoted elsewhere are often means and look much larger.
What is the biggest driver of net worth at 45?
Property equity and pensions. The ONS attributes 40% of GB household wealth to net property and 35% to private pensions — at 45, mortgage paydown and peak-earnings pension contributions do most of the work.
