South Korea has world-class hospitals and universal healthcare through the National Health Insurance Service (NHIS). Foreign residents who stay six months or more are generally required to enrol, which gives access to excellent care in return for income-based premiums and co-payments.
NHIS covers a large share of costs but leaves co-payments and some exclusions, so many Britons add private or international cover for private rooms, English-speaking service and worldwide protection. This guide explains both layers.
Healthcare in South Korea: how the system works
Public system: National Health Insurance Service (NHIS).
South Korea runs universal healthcare through the National Health Insurance Service, which covers a large share of costs at an extensive network of high-quality hospitals, leaving patients a co-payment. Premiums are broadly income- or contribution-based. Foreign residents staying six months or more are generally required to join the scheme.
As a UK resident of South Korea staying six months or more you are generally required to enrol in NHIS, giving you access to excellent hospitals with co-payments. Many expats add private cover for private rooms, uncovered items and regional or worldwide protection. There is no S1 or GHIC route here, and a UK domestic policy will not cover you as a resident.
Is health insurance mandatory in South Korea?
Since 2019, foreign residents staying in South Korea for six months or more have generally been required to enrol in the National Health Insurance Service (NHIS), with premiums that are income- or contribution-based. This is a legal requirement rather than optional. NHIS covers a large share of costs but leaves co-payments and some exclusions, so many expats take private or international cover on top — confirm the current threshold and premium for your visa.
Why British expats take out private cover
NHIS is good value but still leaves co-payments and some exclusions, and public hospitals can mean language barriers and shared rooms. Private or international cover adds English-speaking private care, private rooms and worldwide protection for travel and trips home.
What expat health insurance costs in South Korea
NHIS premiums are income- or contribution-based and billed locally, while a private top-up is a moderate extra. Overall the combination is reasonable, and comprehensive international cover rises with age and the area of cover you select.

How a UK broker helps expats in South Korea
International private medical insurance is a specialist market, and the right policy depends on your visa, your age, your medical history and how much time you spend outside South Korea. A UK-based specialist broker can compare the international insurers available through its service, check that a policy meets any local or visa requirement, and explain what is — and is not — covered before you commit.
A broker can compare only the insurers and policies available through its service, and may receive commission or charge a fee. Ask for the insurer panel, the remuneration disclosure and the total price. Requesting a quote is free and puts you under no obligation to buy.
