UK Pensions for ICWIM Chapter 8: A Deep Dive

ICWIM Chapter 8 (Lifetime Financial Provision) is 13 marks and dominated by UK pensions. The content moves fast through state pension mechanics, DB vs DC plans, annual and lifetime allowances, tax relief methods, and the 2015 "pension freedoms". This guide covers every testable concept end-to-end — including the major Lifetime Allowance abolition in April 2024 that older study material gets wrong.

The three pillars of UK retirement provision

The standard framework (used by the World Bank too) splits retirement provision into three pillars:

The UK state pension provides only about 24% of pre-retirement income on average — the other two pillars do most of the work. This drives the entire financial-planning rationale.

The UK State Pension

Two regimes side by side

State Pension Age (SPA)

• Currently: 66 (men and women equalised)
• Rising to 67: phased between 2026 and 2028
• Rising to 68: originally scheduled 2044-2046, but reviews ongoing for earlier implementation

The triple lock

State pension uprating follows the HIGHEST of three measures each year:

1. CPI inflation
2. Average earnings growth
3. 2.5% floor

This is the "triple lock". It's expensive (Treasury estimates ~£6bn/year cost vs CPI-only) and politically contested. Most reform proposals involve scrapping the 2.5% floor or moving to a "double lock".

Workplace pensions: DB vs DC

Defined Benefit (DB)

The employer commits to paying a specific pension amount in retirement, typically based on a formula:

• Final Salary scheme: uses salary at retirement (or near it). Most generous historically; mostly closed to new entrants now.
• Career Average Revalued Earnings (CARE): uses average of revalued salary across career. Most public-sector schemes are now CARE.
• Accrual rate: typically 1/60 or 1/80 per year of service. 1/60 means 40 years' service = 40/60 = 67% of salary.

Risk sits with the employer — they're committed to paying the pension regardless of investment performance.

Defined Contribution (DC)

The employer (and member) contribute a percentage of salary into an individual fund. The retirement income depends on the fund value at retirement and how it's accessed.

• Risk sits with the member — investment returns determine the pot size
• More portable across employers (member keeps the pot)
• Access flexibility via pension freedoms (since 2015)

Auto-enrolment

Auto-enrolment (introduced 2012) requires UK employers to automatically enrol eligible workers into a workplace pension. Minimum contributions:

Eligible workers can opt out, but they're re-enrolled every 3 years. Auto-enrolment has dramatically increased UK pension coverage but the 8% minimum is widely seen as insufficient — independent reviews recommend gradual rises toward 12%.

Tax relief on pension contributions

Pension contributions get income tax relief at the contributor's marginal rate. There are two operational methods:

Relief at source (RAS)

• Member contributes NET of basic-rate tax
• Pension provider claims back basic rate from HMRC
• Higher/additional-rate taxpayers reclaim the EXTRA relief via self-assessment
• Used by personal pensions, SIPPs, most workplace DC schemes

Net pay arrangement (NPA)

• Contribution deducted from gross salary BEFORE income tax is calculated
• Member gets full marginal-rate relief automatically
• No self-assessment reclaim needed
• Used by most occupational DB/DC schemes

Salary sacrifice

An arrangement where the member gives up some salary in exchange for higher employer pension contributions. Benefits:

• Saves National Insurance (NI) — neither employer nor employee NI on the sacrificed amount
• Employer often passes their NI saving into the pension too
• Simplifies tax administration (no self-assessment reclaim)

Drawbacks: lower headline salary (mortgage/borrowing affordability), affects earnings-related benefits (death-in-service, statutory pay).

Annual Allowance (AA)

The annual allowance caps tax-relieved contributions to pensions per tax year:

• Standard AA: £60,000 (since April 2023)
• Money Purchase Annual Allowance (MPAA): £10,000 — applies once you've flexibly accessed DC benefits
• Carry forward: unused AA from the previous 3 tax years can be brought forward

Tapered Annual Allowance (high earners)

For very high earners, the AA tapers:

• Threshold income > £200,000 AND adjusted income > £260,000 → taper applies
• AA reduces by £1 for every £2 of adjusted income above £260,000
• Minimum tapered AA: £10,000 (once adjusted income reaches £360,000)

Excess contributions above the AA are subject to an income tax charge at the member's marginal rate.

The post-LTA allowances (since April 2024)

The Lifetime Allowance was abolished on 6 April 2024 and replaced with three separate lump-sum allowances:

Excess amounts are taxed at the recipient's marginal income tax rate (for lump sums above LSA / LSDBA). The old 25% / 55% LTA charges are gone.

Pension Freedoms (since April 2015)

Before 2015, DC pension members were largely required to buy an annuity at retirement. The 2015 pension freedoms made this optional and introduced three ways to access DC pensions:

1. Annuity

Exchange a lump sum for a guaranteed income for life. Income is fixed (or indexed); investment and longevity risks transferred to the insurer. Annuity rates have improved substantially since 2022 alongside rising gilt yields.

2. Flexi-Access Drawdown (FAD)

Keep the pension invested and withdraw income flexibly. The member bears investment risk and longevity risk. Provides full flexibility but requires ongoing investment decisions.

3. Uncrystallised Funds Pension Lump Sum (UFPLS)

Take lump sums directly from the pension as needed. Each withdrawal is 25% tax-free, 75% taxable at marginal rate.

Hybrid approaches

In practice, most retirees use a mix — annuity for the security floor (covering essential expenses), drawdown for discretionary spending and capital preservation.

Sequencing risk and risk of ruin

Other UK pensions vocabulary

Inheritance and pensions

Pensions sit outside the estate for IHT purposes (significant planning advantage). Death benefit treatment depends on age at death:

This makes pensions one of the most IHT-efficient ways to transfer wealth — assuming the holder survives long enough to accumulate the pot. The "age 75 cliff" is heavily tested.
