Leaving the UK permanently: what to do with banks, tax, NHS and documents

Leaving the UK permanently is a major step. Whether you are moving for work, retirement, family, study or a long-term lifestyle change, there are several practical things to sort before you go.

Many people focus on visas and flights, but forget about UK-based admin. Tax, pensions, banking, healthcare, property, insurance, voting and official documents can all create problems later if they are not organised before departure.

Official UK guidance for moving, living or retiring abroad highlights areas such as visas, healthcare, tax and pensions as important points to check before leaving. This guide gives you a practical checklist to help prepare.

Check your passport and immigration status

Before leaving the UK, check your passport and the entry requirements for your destination country.

Make sure:

• your passport is valid
• your name matches your certificates and visa documents
• dependants also have valid passports
• you have digital copies of passport pages
• you understand your visa or residence route
• you know whether your destination requires legalised or translated documents

If your passport is close to expiry, consider renewing it before starting a long-term visa or residency process.

Tell HMRC if needed

Tax is one of the most important areas to review before leaving the UK. Depending on your situation, you may need to tell HMRC that you are leaving or have left the UK.

GOV.UK explains that people leaving the UK to work or retire abroad may need to use a P85 form or a tax return, depending on their circumstances. The P85 process is used to help HMRC update your position and, where relevant, deal with UK Income Tax relief or repayment after departure.

Documents to organise include:

• P45, if you have one
• P60s
• payslips
• tax returns
• HMRC correspondence
• National Insurance number records
• pension tax documents
• property income records
• business accounts, if self-employed
• student loan records, if relevant

If you will still receive UK income after moving abroad, such as rental income, pension income or business income, it is sensible to get professional tax advice.

Review your UK tax residence position

Leaving the UK does not automatically mean you stop having UK tax responsibilities. Your position can depend on where you live, how long you spend in the UK, what income you receive and what ties you keep.

Before moving, think about:

• how many days you may spend in the UK each tax year
• whether you will keep a UK home
• whether you will keep working for a UK employer
• whether you will rent out UK property
• whether you will receive UK pension income
• whether you have investments or business interests

Keep clear records of travel dates, income and address changes. These can be useful if you need to explain your tax position later.

Update banks and financial providers

Before leaving, contact your UK bank and financial providers. Some providers allow customers to keep accounts while living abroad, while others may restrict services depending on your new country of residence.

Check:

• whether you can keep your current account
• whether your savings accounts can remain open
• whether your credit cards will still work
• whether your bank needs your overseas address
• whether online banking access is fully set up
• whether two-factor authentication works with your new phone number
• whether you need a UK correspondence address
• whether fees apply for overseas use

Useful documents to keep include:

• bank statements
• savings account records
• mortgage documents
• loan agreements
• credit card statements
• investment records
• financial adviser correspondence

Do not leave banking changes until the last minute. Access can become harder once you are already abroad.

Sort out pensions

If you have UK pensions, organise all pension paperwork before leaving.

Prepare:

• State Pension forecast
• National Insurance contribution record
• workplace pension statements
• private pension statements
• pension provider contact details
• pension beneficiary forms
• pension drawdown or annuity documents
• overseas payment instructions, if relevant

MoneyHelper explains that moving abroad can affect how pensions are paid and taxed, even though many people can still claim UK pension income while living overseas.

Make sure each pension provider has your correct contact details. You may also want advice before transferring pensions or changing how you take pension income.

Consider NHS and healthcare records

If you move abroad permanently, your healthcare arrangements may change. You may need private insurance, local healthcare registration or country-specific documents.

Before leaving, organise:

• NHS number
• GP medical summary
• vaccination records
• prescription list
• dental records
• specialist letters
• children’s immunisation records
• private health insurance documents
• travel insurance documents

If you are moving to a country where UK-funded healthcare arrangements may apply in certain circumstances, check the current rules before relying on them. The NHS Business Services Authority provides information about applying for healthcare cover when living abroad.

Update your address

Create a list of organisations that need your new address. This can prevent missed letters, lost documents and account problems.

You may need to update:

• HMRC
• banks
• pension providers
• insurance companies
• student loan provider
• mortgage lender
• landlord or letting agent
• utility companies
• mobile phone provider
• GP or dentist
• DVLA, if relevant
• professional bodies
• Companies House, if you are a company director
• subscription services

If you do not yet have a permanent overseas address, decide where important post should go temporarily.

Deal with UK property

If you own or rent property in the UK, organise the paperwork before you leave.

If you rent, check:

• tenancy end date
• notice period
• deposit protection details
• final utility readings
• council tax closing account
• checkout report
• forwarding address

If you own property, prepare:

• title documents
• mortgage statements
• buildings insurance
• landlord insurance, if renting it out
• tenancy agreement, if applicable
• property management agreement
• gas safety records
• electrical certificates
• council tax records
• service charge documents

If you rent out UK property after leaving the UK, there may be tax and reporting implications.

Cancel or transfer utilities and subscriptions

Before leaving, make a list of accounts to cancel, transfer or update.

This may include:

• electricity
• gas
• water
• broadband
• mobile phone
• TV licence
• council tax
• home insurance
• car insurance
• gym memberships
• streaming services
• delivery subscriptions
• professional memberships

Download final bills and confirmation emails. These can be useful later for proof of address history or tax records.

Driving and vehicle documents

If you are taking a vehicle abroad, selling it or leaving it in the UK, organise your vehicle paperwork.

Documents may include:

• driving licence
• V5C log book
• MOT records
• car insurance
• no-claims bonus evidence
• finance agreement
• sale receipt
• export paperwork, if applicable
• breakdown cover documents

If you plan to drive in your new country, check whether your UK licence is valid, whether you need an international driving permit, and whether you must exchange your licence after becoming resident.

Voting from abroad

British citizens living overseas may still be able to register to vote in UK Parliamentary elections if they meet the rules. GOV.UK provides guidance on voting when living abroad, including registration and renewal information. The Electoral Commission also explains that British citizens overseas who previously lived in or were registered to vote in the UK can register for UK Parliamentary elections.

Before leaving, consider:

• registering as an overseas voter
• arranging postal voting
• arranging proxy voting
• keeping your last UK address records
• saving electoral registration correspondence

This is easy to forget during a move, but worth sorting if you want to keep voting in UK elections.

Organise important certificates

Official UK certificates can be harder to replace once you are abroad. Order copies before leaving if your originals are missing, damaged or stored somewhere inconvenient.

Useful certificates include:

• birth certificate
• marriage certificate
• civil partnership certificate
• divorce documents
• deed poll or change of name documents
• adoption documents
• death certificates for family matters, if relevant
• degree certificates
• professional qualifications

Keep originals safely and scan digital copies.

Legal documents to review

Leaving the UK permanently can affect legal planning, especially if you have family, property or assets in more than one country.

Review:

• will
• lasting power of attorney
• overseas power of attorney
• property authority letters
• business authorisations
• company documents
• trust documents, if relevant
• probate documents, if relevant
• solicitor correspondence

You may need advice in both the UK and your destination country, especially for inheritance, property or family law matters.

Documents for children and family

If you are moving with children or dependants, prepare their documents carefully.

You may need:

• children’s passports
• birth certificates
• school reports
• vaccination records
• medical records
• parental consent letters
• custody or parental responsibility documents
• adoption documents, if relevant
• special educational needs documents

Schools, visa authorities and border officials may all ask for different forms of evidence.

Do documents need an apostille?

Some UK documents may need an apostille before they are accepted abroad. An apostille confirms that a UK public document, signature or seal is genuine for overseas use.

Documents that may need an apostille include:

• birth certificates
• marriage certificates
• divorce documents
• degree certificates
• police certificates
• powers of attorney
• court documents
• company documents
• solicitor-certified copies

The requirement depends on your destination country and the organisation requesting the document.

Do documents need translation?

If you are moving to a country where English is not the main official language, some documents may need certified translation.

Common examples include:

• birth certificates
• marriage certificates
• legal documents
• school records
• medical records
• pension letters
• financial documents
• powers of attorney

Check whether the translation needs to be certified, sworn or completed by an approved translator.

Create a secure document folder

Before leaving, create a secure physical and digital document system.

Include:

• passport scans
• visa documents
• certificates
• tax records
• pension records
• medical records
• insurance policies
• bank records
• property documents
• legal documents
• emergency contacts

Use strong passwords and secure storage for digital copies. Keep originals in a safe place and avoid carrying every important document together when travelling.

Common mistakes before leaving the UK

Common issues include:

• forgetting to tell HMRC where required
• not updating pension providers
• losing access to UK online banking
• closing accounts too early
• not downloading final bills
• leaving old addresses on important accounts
• forgetting NHS or medical records
• failing to organise children’s school documents
• not checking whether documents need an apostille
• not arranging certified translations in time
• assuming UK tax responsibilities end automatically

A simple checklist can prevent many of these problems.
