The Leaving the UK Checklist: Everything to Sort Before You Go

Deciding to leave the UK and change your life is an incredibly exciting time. But whether you’re just moving abroad temporarily or permanently relocating, there’s always a practical side to the excitement.

What do you need to do before you leave?

This is a practical, UK-side checklist: we'll cover what to sort months before you go. Our guide covers the admin that can bite you later - tax residency, benefits, council tax, healthcare, banking, mail, pets, vehicles, and the boring-but-deadly "final bill" stuff.

The government itself groups the big ones as: council, benefits, pension, student loans, and tax.

What this checklist does not cover is what visa you need for your destination - that's country-specific and changes constantly. We’ve got dozens of country-specific guides that can help you there..

What it does do is get your UK house in order so you don't spend your first month abroad arguing with a call centre from a different time zone!

Before you start anything else

Create a departure pack

You'll be amazed how often you're asked the same details by different organisations:

Before you drive yourself completely crazy, a simple departure pack is great for storing your vital info:

Things like:

• National Insurance number
• Customer reference numbers
• Policy numbers
• Account numbers
• Your last UK address, your new address
• Actual departure date, flight details, etc.

You’re going to find yourself constantly referring to this info, so get ahead of the issue.

Put all your vital details in one place - shared note, a spreadsheet, a dedicated folder. You'll use it constantly.

Start keeping day-counting evidence now

This matters more than most people realise.

UK tax residency has a profound impact on your financial situation - both now, and in the future.

This is assessed under the Statutory Residence Test, and HMRC's own guidance explicitly tells you to keep records showing where you spent days and midnights - travel schedules, booking confirmations, tickets, boarding cards.

If you do nothing else early, do this.

A scrappy Notes app log plus saved travel emails can save you a world of pain later.

The people who get burned are the ones who assume "I obviously left" is sufficient evidence.

HMRC is not exactly known for taking your word for it - and ultimately, you will be the one that ends up picking up the bill for it - if you get it wrong.

Assess your need for the NHS

The NHS is residence-based for most services, not nationality-based.

Will this affect you?

Government guidance explains that entitlement to free healthcare is tied to "ordinary residence" - living lawfully in the UK on a properly settled basis.

So if you move abroad and plan to pop back for a non-urgent operation later, don't assume that it's automatically free.

This assumption has cost people thousands.

In fact, if you are likely to be requiring any kind of operations/surgery on the NHS, we would generally recommend that you go ahead with them before messing your your residency status.

ISAs: don't accidentally break the rules

Another costly mistake that many of us are not aware of until it’s too late.

If you have an ISA and become non-UK resident, you cannot keep paying into it (there are a few limited exceptions for certain Crown employees overseas).

You must tell your ISA provider when you stop being UK resident - but you can generally keep the ISA open and keep your tax relief on what's already inside.

The key word is "contributing."

Existing money stays put.

New money can't go in.

If you're heading to the EU, check your passport now

FCDO travel advice for Schengen destinations is clear: your passport must be issued less than 10 years before arrival and have at least 3 months' validity after the day you plan to leave the Schengen area.

It goes without saying that if you are planning to leave the UK, your passport should be valid for the foreseeable future.

The passport renewal service is famously spotty (unless you pay for fast access), so get on the case early to avoid unnecessary stress and fees.

Early preparation

Once you know that you’re definitely leaving, it’s time to get down to action.

Tell HMRC properly

If you're leaving the UK and want to get your Income Tax right - including potentially claiming back overpaid tax from UK employment - HMRC says you can do this online or via form P85.

If you normally do Self Assessment, it's different: you tell HMRC you're leaving via your tax return by completing the residence section (SA109) and sending it by post.

You cannot use HMRC online services to tell them you're leaving.

Yes, in 2026, you still have to post things to the taxman!

Understand split year treatment

Under the Statutory Residence Test, someone who's UK-resident for a year has to work our whether split year treatment applies, which can split the year into a UK part and an overseas part (for tax purposes).

This is one of those areas where guessing is expensive.

Yes, you can do it yourself, but if your situation is complicated… it’s probably not worth the risk.

We’d say that if your situation is anything other than "I left, got a full-time job abroad, and cleanly cut UK ties," you’ll want to get a tax professional to check it.

As always, the cost of an hour's advice is a fraction of what getting it wrong costs.

National Insurance and State Pension

This one is time-sensitive right now.

The rules for paying voluntary National Insurance contributions while abroad are changing from 6 April 2026, with new eligibility conditions for new applications.

If voluntary NI is part of your plan - often to protect your UK State Pension record - read the new rules before they bite you.

If you're already at or nearing pension age, take the time to understand how payment works abroad.

The State Pension can be paid into a UK bank or a bank in the country you live in.

There's a conversion charge if you choose payment in local currency, but no charge if paid in sterling. Annual increases also depend on where you live - you only get yearly increases in specified countries (EEA, Switzerland, and certain countries with social security agreements).

In others, your pension is frozen at whatever rate it was when you left.

We’d hope that you’d have already prepared for this by the time you make the decision to move - but if you haven’t, you will definitely want to familiarise yourself with the exact country-pension relationship before moving.

Benefits and Child Benefit

If you receive any benefits, tell the DWP you're moving abroad.

They'll tell you whether you can keep getting them.

Child Benefit has specific time limits. It can continue for short periods abroad in certain circumstances - up to 8 weeks for holidays or business, up to 12 weeks for things like medical treatment.

If you intend to go abroad for more than 8 weeks, or move abroad for more than a year, you need to report the change before you go.

Student loans: don't ghost the SLC

You must also tell the Student Loans Company if you're leaving the UK for more than 3 months, by updating your employment details.

"Must" is the operative word.

They will find out eventually, and the conversation gets worse the longer you leave it!

Your repayment amount will get recalculated based on your overseas income and the country's cost of living threshold.

Your UK property

To sell or not to sell?

To rent or not to rent?

There are so many property considerations that it’s tough to offer any specific advice here, given that everybody’s situation is different.

What we can say is that:

Council tax surprises are real. You'll usually have to pay council tax on an empty home, and any discount is entirely up to your local council. Worse yet, councils can choose to introduce premiums on long-term empty homes and second homes. Given the current tax climate in the UK, we can’t see this situation improving anytime soon.

If you sell while non-resident, the deadline is strict. You must tell HMRC within 60 days of transferring ownership - even if there's no tax to pay. Miss that deadline and you're looking at penalties.

If you rent it out, expect UK tax admin. You still need to pay tax on UK rental income. If you live abroad for 6 months or more per year, HMRC classes you as a "non-resident landlord" under the NRLS - even if you're technically UK resident for other tax purposes.

If you want rent paid without UK tax being deducted at source, you can apply using form NRL1.

Healthcare planning

The NHS makes it clear that you should plan your healthcare before you go, including understanding what you'll be entitled to abroad and what you may need to pay for.

If you're moving to certain European countries and might be eligible for an S1 (often relevant for State Pension recipients), you can apply online up to 90 days before you move.

You'll need an address in the country you're moving to - but a temporary address can be used if you don’t have one yet.

Pets

If you're taking a dog, cat, or ferret to the EU, the pet must be microchipped before (or at the same time as) its rabies vaccination.

Then you must wait at least 21 full days after the primary rabies vaccination before travel. You'll also need an Animal Health Certificate from your vet, which is valid for 10 days for EU entry, 4 months for onward travel within the EU, and 4 months for re-entry to Great Britain.

You cannot do this on a whim in the final week unless you enjoy panic, vet waiting rooms, and the specific kind of stress that comes from explaining quarantine rules to a Labrador!

Just as importantly, pet import rules vary from country to country. Check our country guides for specific requirements - or better yet, speak to a pet export agency with experience in moving pets to your destination of choice.

Driving and vehicles

You can’t put an overseas address on your UK driving licence.

Contact the driving licence authority in your new country - in some places you can exchange your UK licence without another test.

If you're taking your vehicle out of the UK for 12 months or more, you must follow the permanent export process, which includes sending the relevant section of the V5C to DVLA. Any vehicle tax refund is usually issued within 4 to 6 weeks.

Mid preparation

As you get towards the final stages of your move, this is often the point where things start to get more stressful. The inbox is mounting with to-dos and your mind is swimming in calculations of “Who do I need to contact next?”

We think a good idea is to set aside one morning every week for a full mental de-brief. Work through your list and mark the status of what you’ve done so far, and still need to do…

Confirm who you need to notify

• Your council: contact them about your move and give a forwarding address. Councils differ on timing - some accept notice 21 days out, others won't take it months in advance. Check your specific council's rules.
• Student Loans: if you haven't already told the SLC, do it now.
• Voting: decide whether you want an overseas vote. Registration must be renewed every 3 years.

Sort your mail

Royal Mail offers redirection to UK or overseas addresses for 3, 6, or 12 months. Set it up if you want to receive your mail directly.

Many expats choose to rely on virtual postbox services, which have their own pros and cons. We have a separate guide for those.

Whatever the case, you want to have a PLAN in place.

Do not rely on "my mate will pop in and send me anything important."

Your mate will forget, and the important thing will be your bank's fraud team trying to reach you about a suspicious transaction.

There’s nothing like getting randomly locked out of your account for not responding to letters from three months ago. Doh!

Lock in pet travel appointments

If you're travelling to the EU, your Animal Health Certificate must be issued close to departure - but book the vet appointment now and make sure the rabies timeline works backwards from your travel date.

Insurance, memberships, and subscriptions

"Tell them you're leaving" is the safe default for everything, especially anything that could later argue you misrepresented your circumstances.

Go through home insurance, car insurance, travel insurance, health cover, life insurance, gym memberships, and anything on direct debit. Cancel or update each one.

Your future self will thank you when you're not paying £49 a month for a gym 3,000 miles away.

Final month

As you approach the departure date, the checklist turns into a countdown. The goal is simple: leave cleanly - with proof.

Council tax and bills

• Confirm your move-out date with the council on their timetable. Make sure they have a forwarding address.
• If your UK property will be empty or a second home, check whether your council applies premiums.

Utilities

Give your electricity and gas supplier at least 48 hours' notice.

Take meter readings on the day you move out. Photograph them. Keep a note of readings and dates, and give a forwarding address. You'll have 28 days to pay the final bill.

Thankfully, many bills are now paperless - but make sure that whatever forwarding address you give will actually be functional (this is why we recommend the virtual postbox option - you can have letters scanned and emailed to you).

All of this matters even more when you're leaving the country; trying to dispute an estimated bill from abroad is really NOT fun.

TV Licence

If you're moving abroad and won't need your licence again before it expires, you can cancel and request a refund.

You can request this up to two weeks before you move.

Driving licence and vehicle admin

• You can't put your overseas address on your UK licence - noted above, but do it now if you haven't.
• If you're permanently exporting a vehicle, follow the DVLA process so records are correct and any tax refund goes to the right address.

Banking and savings

• Be ready to confirm tax residency to your bank if asked - they might request this under exchange-of-information rules.
• If you're becoming non-UK resident, remember you cannot contribute to ISAs.

HMRC paperwork

If you're using P85, get your details lined up: UK employment information, likely your P45, and your leaving date. Submit it all promptly.

If you're in Self Assessment, plan for SA109 and the fact that HMRC online services cannot be used for this.

Health cover

If you're relying on the S1 route and haven't applied yet, you're now in the official "up to 90 days before you move" window.

Don't treat this as optional admin!

Departure week and after

On the day you leave

• Take and photograph final meter readings. Send them to your supplier. Keep your own copy.
• Make sure your council tax position is correctly closed or moved to the new liability if you're keeping the property.
• Double-check mail redirection is active.
• Confirm with your bank that they have a contact number that works abroad.
• Don’t forget the kids!

After you've left

Keep day-counting records going. HMRC is clear that record-keeping for time spent in and out of the UK matters - especially if you'll be back and forth for family, work trips, or Christmas/NYE.

If you later sell UK property while non-resident, don't miss the 60-day deadline. You must report the sale to HMRC even if there's no tax to pay.

Don't assume the NHS works like travel insurance. Entitlement to free NHS healthcare is residence-based. If you're living abroad long-term, plan accordingly and start the process of getting suitable cover immediately.

And breathe…

Most of this isn't complicated.

It's just a lot of it, and the consequences of missing things only seems to surface months later when you're in a different country with a different phone number and a 7-hour time difference from the relevant call centre.

At that point, things become much harder to fix.

Better to prevent the fire than spend endless hours on the phone trying to put it out.

The people who leave cleanly are the ones who treated it like a project: a list, a timeline, an entire folder of confirmations. And the people who don't are the ones still arguing about it on expat forums long after the moment to act has passed.

Do the boring stuff. Do it early. And then enjoy your new adventure!
