The short answer

A policy is portable if it keeps working — on the same terms, without new medical questions — when you move country. For an international family, the most important portable policy is international health insurance with an area of cover that includes every country you might live in. Next come life cover and income protection from insurers that cover people living abroad, and savings and investments held in structures that don't depend on where you live. Expect employer cover, UK-only and local policies, car insurance and the NHS not to move with you. Before every move, check each policy, keep old cover until new cover is confirmed, and tell insurers where you're going.

What "portable" really means

"Portable" is used loosely in insurance marketing. For an international family, a genuinely portable policy should pass five tests:

• It covers you in your new country — not just on holiday there.
• It continues without new underwriting — no fresh medical questions, no new exclusions for conditions you developed while covered.
• The terms don't change because you moved — or, if the premium changes with the area of cover, the cover itself doesn't.
• It pays in a currency you can use, and premiums can be paid from wherever you live.
• It can be claimed on from abroad — with claims handled in English and medical reports from local hospitals accepted.

A policy that fails any of these isn't truly portable. The worst failure is the second: if you have to reapply for cover after a move, anything that happened to your health in the meantime may be excluded — and as you get older, cover can become harder or more expensive to find.

Health insurance: the policy that matters most

For an international family, health cover is the policy most likely to be needed and the hardest to replace. Getting its portability right is the single most valuable thing you can do.

UK policies stop at the border

A standard UK private medical insurance policy isn't designed for people living abroad, and once you move overseas it's no longer valid. If you're relocating from the UK, you'll need an international plan from the day you arrive.

Local plans are built for one country

Thai health insurance from a local insurer can be good value for people settled in Thailand, but it's designed for living here. Cover outside Thailand is usually limited, and local plans often cap the age at which you can join — commonly in the 60s. If there's any chance you'll move on, a local-only plan can leave you needing to start again elsewhere, older and with a longer medical history.

International plans and area of cover

International health insurance is built to move. You choose an area of cover — typically worldwide, worldwide excluding the USA, or a regional zone such as Asia or Europe — and you're covered for treatment anywhere in that area. Excluding the USA makes cover significantly cheaper, because US healthcare is so expensive; ex-USA plans usually still cover emergencies there but not planned treatment. If your family might move between countries in Asia, Europe or the Middle East, an ex-USA worldwide plan can follow you without a new application.

Underwriting and continuity

How a policy was underwritten affects what happens when you move. With full medical underwriting, you declare your history upfront and know exactly what's covered from day one. With a moratorium, conditions you've had in the past five years are excluded until you've gone two clear years without symptoms, treatment or advice. Changing insurers after a move can reset that clock, so keeping one portable plan through several moves is usually better than switching each time.

The NHS is not a portable safety net

Many British families abroad think of the NHS as a back-up: if something serious happened, they'd fly home and be treated. It's important to understand why that may not work.

Free NHS hospital care depends on being ordinarily resident in the UK, not on your nationality, your National Insurance record or owning a home there. People who move abroad permanently lose their entitlement to free NHS hospital treatment. When they visit, they're treated as overseas visitors, and hospital care can be charged at 150% of the cost to the NHS. GP services and A&E treatment remain free for everyone, but follow-up treatment and planned care can be charged.

If you return to the UK to settle, the picture changes again: British citizens who come back to live will most likely be treated as ordinarily resident from the day they arrive. But a family that flies home for treatment while still living in Thailand can face large bills. That's why international health insurance — with cover for trips home and, if needed, repatriation — is so important.

Life cover and income protection

Life insurance and income protection are long-term contracts, often running for 20 years or more. Their portability matters even more than for health cover, because replacing them later means paying more for being older — or not getting cover at all.

International life insurance

Policies from international insurers are designed for people who live abroad and move between countries. Most will cover you wherever you live, with some exceptions for high-risk countries, and premiums don't usually change if you move. They can usually pay in pounds, dollars or euros, and be written in trust. Our guide to international life insurance for expat families explains how to choose.

UK life insurance

Some UK policies continue to cover you abroad; many UK, US and EU insurers won't cover people living permanently overseas, and some policies restrict cover after a period abroad. If you have an existing UK policy, check its terms and tell the insurer you're moving — a policy taken out when you were younger may be worth keeping if it still covers you.

Income protection

Income protection is the least portable of the main protection policies. Many UK policies restrict or stop cover if you move abroad, and claims depend on proving your income and incapacity, which is harder across borders. International income protection exists but is more specialist. Our guide to critical illness and income protection explains the options.

Employer cover: the least portable of all

Many international families rely heavily on an employer's benefits: group health insurance, life cover as a multiple of salary, income protection and sometimes school fees. These can be generous, but they belong to the job, not to you. When the job ends — through a new posting, redundancy, retirement or illness — so does the cover, often immediately.

That creates three risks. First, a gap between jobs can leave the family uninsured. Second, health conditions that developed under the group plan may be excluded on a new individual policy. Third, a family can find itself without life cover at exactly the time its income is least secure.

How to protect yourself

• Ask about continuation options — some group health plans let you switch to an individual plan without new medical questions if you apply quickly.
• Hold some personal cover — a life policy and health plan you own, so protection doesn't depend on one employer.
• Plan for gaps between jobs — know what happens on your last day of employment.
• Check who's covered — partners and children may be on the group plan only as dependants.

Savings, investments and pensions

Portability isn't only about insurance. The way you save and invest can also depend on where you live — and some structures work far better for families who move.

UK ISAs

You can keep an existing ISA and its tax benefits in the UK after you move abroad, but you can't add new money while you're not UK resident. For families planning to save for years abroad, an ISA stops being a vehicle for new savings.

UK pensions

UK pensions generally stay where they are when you move and can be paid to you abroad later. You may still be able to contribute in some circumstances, but tax relief rules change once you leave. Some people consider transferring to an overseas scheme; our guide to international pension transfer considerations explains the trade-offs.

Offshore savings plans and investment bonds

International savings plans and offshore bonds are designed for people who live abroad and move. They can usually continue wherever you live, held in pounds, dollars or euros, and can be written in trust. The tax treatment depends on the country where you're resident when you take money out, so it's worth reviewing before each move. Our guide to offshore investment structures explains how they work.

School fee plans that move with the children

Education is often the biggest long-term cost for an international family — and the one most affected by moves. Children may go to an international school in Thailand, then a school in another country, then a university in the UK, Australia or the US. A savings plan that only works in one country, or in one currency, can leave a family short at the worst moment.

A portable education plan is held in a structure that continues wherever you live, in a currency that matches where the fees will be paid — often pounds for a UK university, dollars for a US one. Because fees rise over time, starting early makes a big difference: a regular monthly plan growing at 8% a year over 13 years can mean more than 40% of the final sum comes from growth rather than your own contributions.

Car, motorbike and home insurance

General insurance is almost always local. Car, motorbike and home policies are tied to the country where the vehicle or home is, so they don't move with you. But some things you've built up can help.

• Get proof of your claims history before you cancel a car policy. Some insurers in your new country may take your record into account.
• Arrange cover before you drive — in Thailand, basic compulsory insurance is limited, and most expats add voluntary cover.
• Insure your belongings in transit — removal insurance is separate from home cover.
• Arrange home contents cover when you move in; your landlord's insurance covers the building, not your possessions.

Currency: a hidden portability problem

An international family often earns in one currency, spends in another and saves in a third. Policies add another layer: premiums may be paid in pounds or dollars, and benefits paid in the same currency. When you move, the currency of your costs changes — and a policy that matched your old life may not match your new one.

Think about the currency of each policy when you review it. Health premiums in dollars can rise in baht terms if the dollar strengthens. A life policy paying pounds may need converting into baht for a family living in Thailand. And school fees in a third country may need a separate plan. When you do move money, a specialist FX provider can usually beat a bank's rate — sometimes by thousands on a large transfer.

Moving on from Thailand — or moving home

Most portability planning focuses on the move to Thailand. But many families move again — to another posting, to be closer to ageing parents, or back home for secondary school, university or retirement. Each of these moves needs the same review.

Moving to another country

Check that your health plan's area of cover includes your new country, and whether the premium will change. Tell your life insurer. Review your savings and investments for the tax rules in your new country, and update wills and beneficiaries — a Thai will still matters if you keep Thai assets.

Returning to the UK

Returning to settle usually restores NHS entitlement from arrival. You may want to keep international health cover for a short overlap, or switch to UK private cover. ISAs can be added to again once you're UK resident. Offshore investments and overseas pensions may be taxed differently once you're back, so take advice before you return — not after.

Our guide to family financial protection when relocating covers the wider move.

Evacuation, repatriation and trips home

Two features of international health plans matter especially to families who live far from home, and they're often confused.

Medical evacuation moves you to the nearest place where appropriate treatment is available if local care isn't adequate — for example, from a small island or a remote province to a major hospital in Bangkok or Singapore. Repatriation returns you to your home country for treatment, usually only if it's medically necessary and you're fit to travel. Neither is the same as flying home because you'd prefer to be treated there.

Most expat health plans also cover trips back to your home country, but how long and for what varies a great deal between insurers. If you spend summers in the UK with family, or children are at boarding school or university there, check exactly what's covered — and for how many days.

• Is evacuation included, and to where?
• Is repatriation included, and on what conditions?
• How long are trips home covered, and for what types of treatment?
• Are children studying abroad covered, and until what age?

When children grow up and move on

International families face a portability question that's easy to overlook: what happens when the children leave. Family health plans usually cover children as dependants only up to a set age, often extended while they're in full-time education. When they reach the limit, or start work, they need their own cover.

The good news is that many insurers let a child move from a family plan onto their own policy without new medical questions, if they apply in time. That can be valuable for a young adult with asthma, allergies or another condition that would otherwise be excluded. Check your plan's rules well before a child's birthday or graduation, and diarise the deadline.

Children studying in another country also need thinking about. A student in the UK may be entitled to NHS care as a resident student, or may need cover depending on their visa and circumstances. A student in Australia or the US will usually need cover that meets local rules. Planning this alongside school and university savings helps avoid surprises.

The most common mistakes

• Assuming a UK health policy works abroad — it doesn't once you live overseas.
• Relying on the NHS as a back-up — hospital care can be charged at 150% of cost.
• Choosing a local plan when you may move on — and having to start again later.
• Relying only on employer cover — it ends with the job.
• Switching insurers with every move — and resetting exclusions each time.
• Cancelling old cover before new cover starts.
• Not telling insurers you've moved — which can put claims at risk.
• Ignoring currency — premiums and benefits that no longer match your costs.

Three real-world examples

These are illustrations, not real clients.

The Harrisons — Bangkok to Singapore and back

James's employer moved the family from Bangkok to Singapore. Their group health plan ended with his Thai contract, and their daughter had developed asthma. Because they'd kept a personal international health plan alongside the group cover, with an Asia-wide area of cover, her asthma stayed covered and nothing had to be reapplied for.

Rachel, 44 — local plan, then a move

Rachel bought a local Thai health plan because it was cheap. Three years later she took a job in Dubai and had to buy a new international plan. Her back problems, treated under the Thai plan, were excluded by the new insurer. With hindsight, a portable plan from the start would have kept her covered.

Paul and Sue — retiring home to the UK

After ten years in Thailand, Paul and Sue decided to return to the UK. They kept their international health cover for the first few months as an overlap, reviewed their offshore bond before they moved, and restarted ISA saving once they were UK resident again.

Your portability checklist

1. List every policy and plan — health, life, income, employer cover, pensions, savings, car and home.
2. For each, ask: will it work in the next country? On the same terms, without new medical questions?
3. Choose international health cover with an area of cover that includes everywhere you might live.
4. Hold some personal protection that doesn't depend on an employer.
5. Tell insurers before you move, and keep old cover until new cover starts.
6. Review savings and pensions for the tax rules in your new country.
7. Match currencies to where your costs will be.
8. Review before every move — including the move home.

Staying secure on the move

Families on the move log in to insurers, banks and pension portals from airports, hotels and temporary homes. Keep policy documents secure, confirm any change of payment details directly with the insurer, and use a private, protected connection on public Wi-Fi.
