Visas and work rights
Start with each country's official route categories for British citizens. Check whether the main applicant, spouse or partner, and dependants can live, work, study, renew, or switch route on the timeline the family needs.
Spouse or partner work
A country can look affordable on two incomes but fail if one adult cannot work quickly. Verify dependant work rights, regulated-profession recognition, employer sponsorship, self-employment limits, and one-income runway.
Children, schools, and childcare
Check school enrollment timing, documents, language support, curriculum change, childcare cost, catchment pressure, special education needs, and whether housing near suitable schools changes the budget.
Healthcare and insurance
Verify public healthcare eligibility, private insurance needs, prescriptions, pregnancy or disability needs, emergency care, and waiting periods. Do this before assuming a familiar healthcare model carries over.
Housing and first-month costs
Family-sized rentals, deposits, temporary accommodation, furniture, utilities, school-area premiums, transport, and exchange-rate movement can change the true shortlist more than headline cost-of-living comparisons.
Pets, documents, tax, and employment
Check pet import timing, vaccines, microchips, civil documents, legalisation or apostilles, tax residence, payroll, pensions, benefits, and whether professional advice is needed before changing jobs or signing leases.
