3.3 Defined Benefit Pension

Explains how DB pensions pay out at retirement, how income and lump sums are calculated, inflation protection, spouse benefits, and whether transfers are worth considering.

3.3 Defined Benefit (DB) Pensions at Retirement

If you’ve built up a Defined Benefit pension — often called a final salary or career average scheme — it will typically pay you a guaranteed income for life. But there are still important decisions to make at retirement.

What Is a Defined Benefit Pension?

A Defined Benefit (DB) pension promises a pre-determined annual income at retirement, based on:

  • Your salary (final or career average)
  • Your years of service
  • The scheme’s accrual rate (e.g. 1/60th or 1/80th)

You don’t need to manage investments — the scheme takes responsibility for funding the promised benefits.

How Is Your Pension Calculated?

Here’s a typical formula:

Annual pension = Final salary × Years of service × Accrual rate

Example:

  • Final salary = £48,000
  • Service = 25 years
  • Accrual rate = 1/60th
  • Pension = £48,000 × 25 ÷ 60 = £20,000 per year

Do You Get a Lump Sum?

Yes — most DB schemes allow you to commute part of your pension into a tax-free lump sum.

  • The default is often no lump sum unless you choose to reduce your annual pension
  • Commutation rate is typically £12–£20 per £1 of pension given up

Example:

  • Full pension = £20,000
  • You take £60,000 lump sum
  • Pension reduces to ~£17,000 depending on the scheme

⚠️ The maximum lump sum is usually capped at 25% of the calculated value, and subject to the post-LTA Lump Sum Allowance (typically £268,275)

Is the Pension Income Inflation-Protected?

Usually, yes — most DB schemes increase your pension annually in line with:

  • CPI or RPI inflation, capped (e.g. 2.5% or 5%)
  • Some public sector schemes offer full inflation linking

This helps protect the value of your income in retirement.

‍‍Is There a Spouse’s Pension?

Yes — DB schemes typically include a survivor’s pension:

  • Often 50% or 2/3 of your pension
  • Paid to a spouse or civil partner after your death
  • Some schemes offer dependent children’s benefits too

Reducing your pension at retirement (for higher lump sum or early access) also reduces the spouse’s pension.

What Age Can You Take a DB Pension?

Most DB schemes have a Normal Retirement Age — usually 60 or 65.

  • You can often take it early, but your pension will be reduced for each year taken early (e.g. 4–6% per year)
  • You may also be able to defer for a larger pension

Each scheme has different actuarial factors — check your provider’s retirement options.

Can You Transfer a DB Pension?

Yes — but only before you’ve started drawing it.

  • You can transfer your DB pension into a Defined Contribution (DC) scheme, such as a SIPP
  • This gives flexibility (drawdown, lump sums), but you give up the guaranteed income

Key Rules:

  • Advice is mandatory if the transfer value is over £30,000
  • Transfers are not allowed once you’ve started taking income

⚠️ FCA and regulators warn that DB transfers are often unsuitable for most people.

When Might a Transfer Be Worth Considering?

Transferring may be worth exploring if:

  • You have no dependants and want to maximise access
  • You have reduced life expectancy
  • You want to pass the pension on tax-free
  • You have significant other income/assets
Most people are better off keeping a DB pension — but regulated advice is essential.
