What does it actually cost to raise a family of four abroad? This comparison draws on the detailed 3-tier monthly budgets in our twenty per-location guides to give you a single reference table — from the cheapest destinations (Portugal, Spain, Italy) to the most expensive (Switzerland, Hong Kong, Singapore). Note that salary levels also vary: a cheap cost of living is only useful if the local or expat job market supports a matching income.
Key takeaways
- Portugal, southern Italy, and Spain are the cheapest working-abroad destinations for UK families
- Switzerland, Singapore, and Hong Kong are the most expensive — annual family costs exceed £90,000–£114,000
- School fees are often the single biggest cost driver in expensive destinations (£20,000–£70,000/year for two children)
- The net financial position (salary minus costs) often looks more similar across destinations than gross costs suggest
- Voluntary UK NI contributions (£824/year) are needed in destinations without a social-security agreement

What the cost rankings mean in practice
The cheapest destinations — Portugal, southern Italy, Spain — are only "cheap" if you can earn enough there. In practice, local salaries in these markets are significantly lower than UK salaries, and expat postings in Lisbon, Madrid, or Milan come with fees that push effective costs above the UK median.
The most expensive destinations — Switzerland, Singapore, UAE — pay commensurately higher salaries. The net financial position (take-home pay minus family costs) often looks more similar across destinations than the gross cost comparison suggests. The real differentiators are:
- School fees: In destinations where expat families must pay for international schooling, a family with two school-age children spends £20,000–£70,000/year in fees alone.
- UK pension record: Destinations without a social-security agreement (Australia, UAE, Singapore) require voluntary UK NI contributions (£824/year for Class 3 in 2026/27) to keep accruing State Pension qualifying years. Over a five-year posting, this is a £4,120 additional cost if handled proactively.
- UK Inheritance Tax domicile: Regardless of where you live, your UK domicile status means your worldwide estate may remain subject to UK IHT. Use our estate planning tools to model this.
