Start with a blank page and write down why you might move. Be specific enough that the reason can rule somewhere out. “More freedom” could mean being able to spend afternoons with your children, travelling to three client markets without overnight flights or keeping enough after housing costs to work fewer days. Each version leads to a different shortlist. If a place does little for the reason you want to move, its appeal as a destination may have very little bearing on your decision.
The goal is to finish with two or three places you could explain to your family and investigate properly. That means collecting enough evidence to see how you would arrive, how you would support yourself, and what an ordinary week would look like. It also means giving every promising place a fair hearing. A city you have never visited might fit your constraints better than the destination you already know from holidays.
Write the brief before you look at countries
Pick a date horizon. A move you could make in six months needs a different brief from a move you might make once your children finish school. Write down who is moving, who needs to work, who needs to study and who needs regular care. List commitments that will remain where you are, such as a director’s role, a parent you visit regularly or a property with a tenant. Make a separate note of your citizenships, current residence permissions and any expiry dates. Those are inputs to the research rather than guesses you need to resolve immediately.
Agree on two or three requirements that really are firm. A child needs a particular educational provision, for instance, or one partner needs access to an industry that requires a local licence. Add preferences separately. Sunshine, walkability and access to the sea might influence the final choice, but they are easier to trade against each other than the ability to remain together as a household. If two people are making the decision, ask them to write their lists independently first. Comparing them can reveal different reasons for the move before time and money go into visits.
Put a plausible legal route beside every place
Look at the destination’s official immigration pages. Start with the kind of stay that matches what you plan to do. Being admitted for a short visit and having permission to live or work there are separate questions. Check what activities a route allows, whether you need a sponsor or proof of income, and whether it has conditions you can sustain. If you’re self-employed, own a company or plan to work for overseas clients, describe those activities explicitly when seeking advice. A route’s name is a poor guide to what it allows in practice.
Repeat the check for everyone travelling with you. A principal applicant’s route may have different rules for a partner or children. Use the actual documents and circumstances for each person, especially if your household has more than one nationality. Record the official source, the date you checked it and the unanswered question. “We think this works” is a fine reason to investigate. For a commitment such as a school deposit or a notice to your employer, you will want a stronger basis.
Compare an ordinary month
Build one budget per candidate in the local currency. Use the same headings, such as rent, bills, childcare, schooling, travel, healthcare, professional costs and an allowance for returning home. Work out what changes at the beginning and end of the first year. The first month can include deposits and temporary accommodation. Later months may include annual school fees, insurance renewals or a trip that the first month’s forecast missed. Mark any amount you have only estimated so you can replace it with a quote.
Then try a week on paper. At what time would you start work if your team were still in Britain? How would you get home after a late meeting? Which supermarket, clinic and nursery would you use? If you have regular UK commitments, search for a journey on the day you usually need it and include the time at each end. Look for a second way to make the trip when the first is unavailable. An airport that looks close on a map can be hard to reach at five in the morning, and a frequent summer service tells you little about a Tuesday in winter.
Build the shortlist in five passes
- Collect five to eight plausible places. Include at least one place you already know and one you know mainly through research. Write a sentence for each explaining what it might offer that you cannot readily get where you are now.
- Record the route that would let each person live there. Include the work and study questions. Where the official material leaves a gap, write a specific question such as “Can my partner continue working for their existing employer under this permission?”
- Pick one realistic neighbourhood per place. Find recent listings or ask a local agent what you could actually rent within budget. Compare realistic areas in each place rather than comparing the capital city’s best district with a distant suburb elsewhere.
- Run the first-year cost and travel checks. Include a downside case such as a slower sales year, a currency swing or regular visits to family. Record which numbers come from live quotes and which need confirmation.
- Keep the strongest two or three, with one open question each. Give each place a reason to stay on the list and a concrete reason it might come off. That gives your next visit or conversation something useful to settle.
Separate the options that work from the ones that need a change
Imagine a founder with a UK team, a partner who wants to keep working and one school-age child. City A has good links to clients, but the family is still checking whether the partner can work. City B looks stronger for employment and schools, but makes the founder’s monthly meeting expensive and tiring. City C has a route that looks promising and affordable rent, though the family has never spent a working week there. Those are three different kinds of uncertainty. The family can take a written question about the partner’s permission to an immigration adviser, test alternative meeting schedules for City B and plan an ordinary visit to City C.
Run the same exercise if one person plans to move first. The expense and complexity of keeping two homes can change the ranking, as can the availability of flights or support for the people who stay behind. Likewise, if a candidate only works after a business sale or once you qualify for a particular permission, mark the event the plan depends on and keep an option that works sooner. The shortlist should reflect the choices you actually have at different times.
End with a decision you can revisit
- Keep the official route and the last date you checked it.
- Save the specific neighbourhood, indicative costs and travel evidence.
- Write down who can answer the one open question that could change your decision.
Give the shortlist a review date and store the evidence in one place. Make it easy for a partner or adviser to see where the numbers came from. If the choice depends on business taxation or on when you cease UK tax residence, bring your actual timetable and company details to an adviser who can work across both places.
A place can move up when an important question gets a good answer. It can also drop when the evidence changes. If nothing survives, look again at the purpose of the move and whether a different city, a later date or a simpler set of commitments would work. A shortlist that forces a real choice between two credible lives is more useful than an impressive ranking of destinations you could never make work.
