🇰🇷 South Korea · 🇬🇧 UK
*By Priya Mehta, The Global Office
Renting a flat in Seoul may require handing a stranger the equivalent of $150,000 — which you get back, in full, two years later, assuming the stranger has not lost it. Raising a toddler in Outer London costs around £22,000 a year in nursery fees, which you do not get back under any circumstances. Expatistan's October 2025 data puts London's cost of living roughly 160% above Seoul's, one of the widest gaps between two rich-world capitals, yet Koreans spend so much on private tutoring that the country's own statistics office treats it as a structural economic problem. Neither country is cheap. They have simply chosen entirely different things to be ruinously expensive.

| ✅ Do | ❌ Don't |
|---|---|
| Register with NHIS promptly — mandatory for residents, and a GP visit can cost less than a coffee | Don't sign a jeonse contract without deposit insurance (HUG) and a registered priority claim |
| Understand the wolse (monthly rent) vs jeonse (lump deposit) trade before house-hunting | Don't wire a jeonse deposit without verifying the landlord's mortgage position — fraud is a national news genre |
| Budget for hagwon (private academy) fees if you bring school-age children | Don't expect council-style local services; the state is lean outside health and transit |
| Use the T-money transit network — world-class and startlingly cheap | Don't assume "low cost of living" includes housing in Gangnam; it does not |
| Negotiate employer housing support — standard in expat packages | Don't skip the neighbourhood office (jumin centre) registration; everything downstream needs it |
| ✅ Do | ❌ Don't |
|---|---|
| Claim the expanded free childcare hours if you qualify — from 2025 they extend to nine-month-olds of working parents | Don't underestimate nursery costs before subsidies; London full-time care rivals a junior salary |
| Register with a GP the week you arrive — NHS care is free at point of use, but queues start at registration | Don't ignore council tax when budgeting rent; Band D runs roughly £1,400–£2,800 a year |
| Check your National Insurance contributions — they gate your future state pension | Don't expect your tenancy deposit to exceed five weeks' rent; that cap is the law |
| Use ISAs for tax-free saving | Don't assume "free healthcare" means fast healthcare; private insurance exists for a reason |
| Compare energy tariffs annually; loyalty is punished | Don't rent without checking the EPC rating — Victorian charm is a heating bill |
Daily life in Seoul is one of the developed world's better bargains. NHIS, the compulsory national health insurance, delivers doctor visits for ₩5,000–₩25,000 ($4–$20), prescriptions with token co-pays, and dental cleanings for the price of a London sandwich meal deal. Transit is superb and nearly free by European standards; eating out costs less than cooking badly. The catch arrives in two instalments. The first is housing: the jeonse system asks tenants for a deposit of 50–80% of a property's value — averaging around ₩600 million (roughly $450,000) for a standard Seoul apartment — in exchange for two rent-free years. The system is now retreating: monthly-rent contracts hit a record 64.6% of Seoul leases in early 2025, up from 40% in 2021, driven by a wave of jeonse fraud and tighter deposit-insurance rules.
The second instalment is children. Public childcare is heavily subsidised and parental allowances have grown as the government battles the world's lowest fertility rate, but the hagwon economy — private evening academies — consumes household budgets on a scale the OECD politely calls exceptional. Korean welfare is thin by European standards outside health insurance; the family, not the state, remains the assumed safety net, which is precisely why families are so expensive to run.

Britain inverts the formula. Daily costs — rent, transport, energy, the fabled £7 pint — are punishing, and London's childcare is the stuff of parliamentary inquiry: the House of Commons Library's briefings track full-time nursery costs that in Outer London approach £22,000 a year, though the expansion of funded hours from September 2025 (30 hours for working parents of children from nine months) has begun blunting the worst of it. Council tax adds £1,400–£2,800 for a typical Band D home, and National Insurance takes 8% of mid-band earnings on top of income tax.
What the money buys is a floor. The NHS remains free at the point of use — waiting lists included at no extra charge — Universal Credit's childcare element covers up to £1,032 a month for one child, and the state pension, statutory sick pay, and housing benefit form a mesh that Korea simply does not weave. Deposits are capped at five weeks' rent and held in government-backed protection schemes, a sentence that reads as science fiction to anyone who has wired ₩200 million to a Korean landlord on faith. Hofstede Insights, for what it is worth, scores Korea 85 on uncertainty avoidance against the UK's 35 — yet it is the anxious country that built housing on trust, and the relaxed one that regulated deposits to the week.
The comparison defeats the usual arithmetic. Numbeo and Expatistan agree Seoul is dramatically cheaper, and for a childless professional on an expat package — company flat, NHIS card, ₩9,000 lunches — it is one of the best value capitals on earth. Add children and the ledger flips: British parents are rescued (partially, eventually) by funded hours and free schooling with no tutoring arms race, while Korean parents enter the hagwon economy, where opting out feels like unilateral disarmament. The deeper difference is where each society stores risk. Britain socialises it — taxes are high, and falling is cushioned. Korea privatises it — daily life is cheap, and your deposit, your tutoring budget, and your retirement are your own problem.

r/korea — A long-running theme in housing threads: expats who fell in love with jeonse's rent-free arithmetic until reading about deposit fraud cases, and now recite the checklist like a catechism — registered move-in date, priority claim, HUG insurance, landlord's mortgage certificate — before wiring anything.
Quora — A parent living in Seoul described taking their son to a paediatric clinic, walking out with an examination and prescriptions for about ₩12,000 — nine dollars — and spending the evening recalculating what their family had paid for equivalent visits back home.
Internations Seoul — A recurring piece of advice for arriving professionals: make employer housing support the first negotiation item, not salary — a company that shoulders the jeonse deposit or key money is worth more than a 10% pay bump, and locals know it.
r/london — A parent posted that their second child's nursery place would consume their entire post-tax salary, prompting the thread's most-upvoted reply: London childcare is a means test for whether both parents' careers deserve to survive — with the 2025 funded-hours expansion the first answer that wasn't simply "no."
Decide what you want to pay for. If you are single or a double-income couple without children, Seoul offers a materially better life on the same salary: healthcare that costs pocket change, transport that works, food that shames London's. If you have or plan children and no expat package, Britain's high sticker price buys funded childcare hours, free schooling without a tutoring arms race, and a welfare mesh that catches falls Korea leaves to the family. The jeonse system is the whole choice in miniature: extraordinary value, provided you personally carry the risk.
What I'd tell a friend over a drink: Seoul charges you a fortune once and gives it back; London charges you a little every single day and doesn't.
