Moving Abroad: The Pros, Cons and Essential Things to Consider
Moving abroad can be one of the biggest decisions you make. A new country can offer different career opportunities, a new lifestyle, cultural experiences and the excitement of starting again somewhere unfamiliar.
However, relocating overseas is very different from taking a holiday. Before you pack your bags, you need to consider practical issues such as immigration requirements, healthcare, employment, housing, taxation, finances and your connections with family and friends.
The idea of living somewhere warmer may sound appealing, but successful international relocation requires much more than good weather.
How Many British People Live Abroad?
The exact number of British nationals living overseas is difficult to establish.
The UK’s Office for National Statistics explains that it does not produce a definitive estimate of how many British nationals currently live abroad because comprehensive overseas data is not available. The ONS reported in 2026 that UN data estimated at least 4.8 million people born in Britain were living overseas in 2024, although the figure is incomplete because more than 70 countries were not included in that dataset. It also measures country of birth rather than British nationality.
The frequently quoted figure of 5.5 million British people living abroad comes from much older estimates. It should therefore not be presented as a current official figure.
What is clear is that moving abroad has long been an option considered by British workers, retirees, families, students and entrepreneurs.
If you are considering joining them, there are several important factors to examine first.
Leaving Friends and Family Behind
One of the biggest challenges of moving abroad is creating distance from the people you know.
You may no longer be able to meet friends or family members whenever you want. Birthdays, celebrations and important family occasions can also become more difficult to attend.
Technology makes communication much easier than it once was. Video calls, messaging services and social media can help you maintain regular contact, but they do not completely replace being physically present.
The Benefits of Building a New Social Circle
Moving abroad can also introduce you to people from completely different backgrounds.
You may meet:
- Local residents
- Other expatriates
- International professionals
- Neighbours
- Members of community organisations
- People who share your hobbies
Making local friends can help you understand your new surroundings and adapt to everyday life.
The key is not to choose between your old and new relationships. With good planning, you can maintain important connections at home while building a new social network abroad.
Living in Another Country
Living somewhere for several weeks as a tourist is very different from living there permanently.
A holiday allows you to focus on the attractions, restaurants and enjoyable experiences. Everyday life involves paying bills, dealing with bureaucracy, shopping, commuting, finding healthcare and understanding local rules.
You may initially experience culture shock.
Everyday customs can differ significantly, including:
- Greetings
- Personal space
- Communication styles
- Meal times
- Working practices
- Family traditions
- Religious customs
- Driving habits
- Social expectations
Understanding these differences can make the transition considerably easier.
Learning the Local Language
Language can be one of the biggest challenges when moving abroad.
Even if English is widely spoken in your chosen destination, learning at least some of the local language can make everyday life easier.
You may need the language for:
- Shopping
- Healthcare
- Government services
- Banking
- Housing
- Transport
- Meeting neighbours
- Understanding official documents
You do not need to become fluent before moving. Learning basic phrases before your relocation can give you confidence, while continued practice after arrival can help you integrate into your new community.
The Attraction of Better Weather
A warmer climate is one reason some people consider moving abroad.
However, weather should not be the only factor behind your decision.
A destination that looks perfect during a two-week holiday may feel very different after several months.
Before moving, consider the entire climate:
- Summer temperatures
- Winter temperatures
- Rainfall
- Humidity
- Extreme weather
- Air quality
- Seasonal tourism
- Access to air conditioning or heating
Visit the country during more than one season if possible. Experiencing everyday life outside the holiday period can give you a much better understanding of what living there will actually be like.
Your Cost of Living May Change
Another common reason for considering life abroad is the possibility of reducing living expenses.
However, you should never assume that another country will automatically be cheaper.
Compare your expected costs for:
- Rent or mortgage
- Utilities
- Food
- Transportation
- Healthcare
- Insurance
- Taxes
- School fees
- Internet and mobile services
- Leisure
- Flights home
- Emergency expenses
A country may have inexpensive restaurants but expensive imported products. Another may offer affordable housing outside major cities but significantly higher prices in popular expatriate areas.
Create a realistic monthly budget before making your decision.
Understand Visa and Residency Requirements
A major difference between taking a holiday and moving abroad is immigration status.
Depending on your destination and circumstances, you may need:
- A work visa
- Residence permission
- A retirement visa
- A digital nomad visa
- A student visa
- Proof of income
- Health insurance
- Police clearance documents
- Proof of accommodation
- Financial records
Do not assume that entering a country as a tourist gives you the right to live or work there.
Visa and residency rules can also change. Always check the official immigration website of the country you intend to move to before making long-term arrangements.
For British citizens, GOV.UK advises people moving or retiring abroad to check the relevant country-specific guidance, including visas, residency, healthcare, tax and pensions.
Healthcare Is a Major Consideration
Healthcare should be one of the first things you investigate.
Find out:
- How the local healthcare system works
- Whether residents are entitled to public healthcare
- Whether private insurance is required
- What your insurance covers
- How prescriptions work
- How emergency care is provided
- Whether your existing healthcare arrangements continue
Do not assume that a health card or travel insurance policy automatically provides comprehensive healthcare after a permanent move.
For example, GOV.UK explains that British citizens working or living abroad may have different healthcare arrangements depending on their country, employment status and circumstances. People moving abroad long term may need to register with the local healthcare system or obtain private insurance.
Think Carefully About Tax
Tax can become complicated when you move abroad.
Leaving the UK does not automatically mean that you have no further UK tax obligations.
Your circumstances may involve:
- UK employment income
- Rental income
- Investments
- Pensions
- Property
- Foreign income
- Tax residency
- Double-taxation agreements
GOV.UK states that people leaving the UK permanently or going abroad to work full-time for at least one tax year may need to notify HM Revenue & Customs.
Your new country may also tax your worldwide income depending on its rules.
If you have significant assets, investments, property or business interests, obtaining professional tax advice before moving can be worthwhile.
Consider Your Pension
If you are approaching retirement, understand how moving abroad could affect your pension before making the move.
The UK government recommends contacting the International Pension Centre when moving or retiring abroad. Your pension may also be subject to tax depending on where you live and the relevant tax agreements.
You should investigate:
- State Pension payments
- Private pensions
- Pension taxation
- National Insurance contributions
- Currency exchange
- Banking arrangements
- Local retirement requirements
Do not base your retirement decision solely on the cost of accommodation or food.
Employment and Remote Work
Working abroad has become more flexible, but remote work does not automatically remove immigration or tax obligations.
Before working from another country, check:
- Whether your visa permits employment
- Whether your employer allows overseas work
- Where you are considered tax resident
- Whether social-security contributions are required
- Whether your employer needs local registration
- Whether professional licensing applies
The rules can be particularly complicated for people working remotely for a company based in another country.
Get professional advice if your employment arrangement crosses international borders.
Housing: Rent Before You Buy
Buying property immediately after moving abroad can create unnecessary financial risk.
If possible, consider renting initially.
This gives you time to understand:
- Local neighbourhoods
- Transport links
- Property prices
- Local schools
- Healthcare access
- Noise levels
- Seasonal changes
- Community life
A neighbourhood that looks attractive during a short holiday may not be ideal for everyday living.
Renting first can give you greater flexibility while you learn how your new home actually works.
Build an Emergency Fund
Moving abroad involves unexpected costs.
You may need to pay for:
- Deposits
- Temporary accommodation
- Immigration applications
- Legal documents
- Moving expenses
- Flights
- Furniture
- Insurance
- Healthcare
- Emergency travel
Maintain an emergency fund that can cover unexpected expenses and, ideally, several months of living costs.
This is particularly important if your income will change after relocation.
Keep Important Documents Accessible
Create secure digital and physical copies of important documents.
These may include:
- Passport
- Birth certificate
- Marriage certificate
- Education certificates
- Employment records
- Insurance documents
- Medical records
- Driving licence
- Visa documents
- Property documents
- Financial records
The UK’s current foreign-travel checklist recommends keeping backup access to important travel and accommodation information and ensuring you have appropriate documents and insurance.
Don’t Forget Travel Insurance
Moving abroad does not eliminate the need to think about insurance.
If you are travelling before your permanent relocation, make sure your travel insurance covers your itinerary and planned activities.
The UK’s Foreign, Commonwealth & Development Office recommends arranging appropriate travel insurance and checking that it covers the destination, duration and activities involved.
For permanent residents, investigate appropriate local health, property and liability insurance as well.
Research Your New Culture
One of the greatest benefits of living abroad is experiencing a different culture.
Take time to learn about:
- Local history
- Food
- Festivals
- Religion
- Family traditions
- Business etiquette
- Social customs
- Local laws
Avoid assuming that customs from your home country will apply everywhere.
Being willing to learn can help you adapt and build stronger relationships with local people.
The Advantages of Moving Abroad
Relocating overseas can provide experiences that are difficult to obtain by simply taking holidays.
Potential benefits include:
A New Lifestyle
You can experience a different pace of life and discover new ways of working, socialising and spending your free time.
New Experiences
Everyday activities can become opportunities to learn.
Shopping in a local market, learning a new language or attending a traditional festival can provide experiences that tourists may only encounter briefly.
New Career Opportunities
Some countries and cities have growing international business communities and opportunities for skilled professionals and entrepreneurs.
Personal Growth
Living outside your familiar environment can encourage independence, adaptability and confidence.
Travel Opportunities
Being based in another country can make it easier to explore nearby regions and countries.
However, these benefits should be weighed against the practical challenges of relocation.
The Disadvantages of Moving Abroad
Moving overseas is not automatically a better life.
Potential challenges include:
- Homesickness
- Language barriers
- Cultural differences
- Immigration bureaucracy
- Distance from family
- Healthcare costs
- Tax complications
- Employment uncertainty
- Currency fluctuations
- Difficulty finding accommodation
- Social isolation
Understanding these challenges before moving can help you prepare for them.
Try Living Abroad Before Making the Permanent Move
One of the best ways to test your decision is to spend an extended period in the destination before committing to permanent relocation, where immigration rules permit it.
A holiday may tell you that you like a place.
Living there for several weeks or months can tell you whether you actually want to make it home.
Try to experience ordinary life:
- Shop at local supermarkets
- Use public transport
- Work your normal hours
- Visit healthcare facilities
- Explore residential neighbourhoods
- Check rental properties
- Meet local residents
- Experience less tourist-oriented areas
This can reveal issues that are easy to overlook during a short holiday.
Create a Moving-Abroad Checklist
Before making the final decision, work through a checklist.

Moving Abroad Is More Than Chasing Sunshine
The original appeal of moving abroad may have been simple: warmer weather, new experiences and a different lifestyle.
Today, international relocation requires much more careful planning.
A successful move depends on finding a destination that works for your finances, career, healthcare needs, family situation and long-term goals.
The best destination is not necessarily the one with the most sunshine or the cheapest restaurants. It is the place where you can realistically build the life you want.
Final Thoughts
Moving abroad can be exciting, challenging and deeply rewarding.
You may discover a new culture, make lifelong friendships, develop new skills and experience a lifestyle that would not have been possible at home.
At the same time, you should approach the decision realistically. Research immigration rules, healthcare, taxation, housing, employment and the cost of living before committing.
If possible, spend an extended period in your chosen destination before making the permanent move.
Most importantly, do not treat moving abroad as an escape from every problem. You will take some challenges with you. The goal is to determine whether the opportunities and lifestyle offered by your chosen destination genuinely match your needs.
Pack your bags when the practical details make sense—not simply because the weather looks good.
