UK Pension System

UK pensions are usually thought of as a three-tier structure. Tier 1 is the state-run State Pension; tier 2 is the auto-enrolled Workplace Pension through your employer; tier 3 is private pensions (SIPP, etc.) you set up yourself. Korea's National Pension corresponds to tier 1, while tier 2 is broadly similar to Korea's auto-enrolled DC retirement plans.

Tier 1 — State Pension

• Funding: comes from National Insurance (NI) contributions, not general taxation. Employees pay NI Class 1; the self-employed pay Class 2 / 4.
• Eligibility: generally at least 10 years of NI contributions to qualify for any State Pension; 35 years for the full new State Pension (flat-rate maximum).
• Amount: the full rate is paid as a flat weekly amount, uprated each year by the "triple lock" (the highest of wage growth, inflation, or 2.5%). The full new State Pension is around GBP 230/week as of 2026, but the exact figure changes every April — check the official site.
• State Pension age: currently 66, scheduled to rise to 67 by around 2028. A move to 68 in the 2040s is being discussed.

Tier 2 — Workplace Pension

• Auto-enrolment: employers must auto-enrol workers aged 22 to State Pension age earning above about GBP 10,000/year (introduced 2012).
• Minimum contributions: typically 8% total (5% employee + 3% employer); some sectors and employers go higher.
• Type: mostly defined contribution (DC). Public sector schemes (NHS, teachers) keep some defined-benefit (DB) but these are shrinking.
• Tax relief: employee contributions get income tax relief.

Tier 3 — Private pensions

• SIPP (Self-Invested Personal Pension) is the most common vehicle, often paired with an ISA (Individual Savings Account) for tax-efficient retirement saving. This is general guidance, not investment advice.

Things to watch as a Korean resident

• UK–Korea social security treaty (in force 2000, amended 2017): you can combine Korean National Pension contributions with UK NI to meet the qualifying-years test. Even if you only work 5 years in the UK, those contributions don't disappear — totalisation is recognised when you claim from either side. Amounts, however, are calculated only on each country's actual contributions.
• Check your NI record: Check your State Pension forecast on GOV.UK shows your contribution years and projected amount. Missing years can sometimes be filled with voluntary Class 3 contributions.
• Receiving from abroad: the State Pension can be paid into a Korean account. But uprating (the triple lock) doesn't apply to residents in some non-treaty countries — check Korea's classification.
• Double taxation: under the UK–Korea tax treaty, the same pension income won't be taxed twice. Tax authority depends on your country of residence — consult a tax adviser before relocation.

This is general guidance as of 2026; figures, ages, and rules are updated each April.
