When to renew a UK passport, and how long it takes

Renew too early and you throw away months you have already paid for. Renew too late and you pay two or three times the standard fee to get the same document in a hurry. The gap between those two mistakes is wider than most people think, and it moves depending on where you are going.

How long it takes

HM Passport Office publishes a single headline figure for standard applications: you will usually get your passport within 3 weeks. Two qualifications come with it. The processing time starts from when it receives your documents, not from when you press submit, and it may take longer than 3 weeks if more information is needed or if you have to be interviewed, in which case it says it will tell you within 3 weeks.

Both online and paper applications quote the same standard timeframe. The paper route costs more, not less time.

Three weeks is a usual case, not a guarantee, and demand is seasonal. Renewing in January for a July trip is a different proposition from renewing in April for a July trip, even though both look like plenty of time on a calendar.

The rule that decides how early is too early

Since 10 September 2018, HM Passport Office no longer adds unused months from your old passport to your new one. Before that date, up to 9 remaining months were carried over. Now the new passport simply runs 10 years, or 5 for a child, from its own date of issue.

That changes the arithmetic of renewing early. Renew with 11 months left and those 11 months are gone. Over a lifetime of passports, habitually renewing a year early costs roughly one passport in ten.

So the sensible answer to when you should renew is: when you actually need to, plus a working margin, rather than at the first sign of the expiry date approaching.

Working out when you actually need to

Your deadline is not your expiry date. It is set by the strictest rule that applies to the trips you are likely to take.

• Travelling to the Schengen area. Your passport needs an expiry date at least 3 months after you plan to leave the Schengen area, and a date of issue less than 10 years before you arrive. Whichever of those falls first is your real deadline.
• Travelling further afield. Six months of validity from arrival is a common requirement outside Europe, so a six month buffer is a reasonable planning assumption if your destinations vary.
• Not travelling for a while. An expired passport is not an emergency in itself, but it becomes one the moment a trip is booked, and applications are not faster because you did not need it sooner.

If your passport was issued in 2018 or earlier, check the issue date rather than only the expiry date. A passport with extra months carried over can hit its tenth birthday well before it expires, and for European travel that tenth birthday is the date that ends its useful life.

A planning rule of thumb

The checker on this site runs both tests for a chosen country, which is quicker than doing it on paper and less prone to counting months wrong.

Do not book travel first

GOV.UK's advice on this is unusually direct: do not book travel until you have a valid passport, because your new passport will not have the same number as your old one. Booking a flight against a passport number that is about to change is a way of creating a second problem on top of the first, since the details on the booking and the details on the document have to match.

What you can do if you have left it late

There are two chargeable services for urgent cases, both of which require an appointment at a passport office.

• 1 day Premium service, £239.50, or £253.50 for the 54 page frequent traveller passport. The earliest appointment is 2 days after you apply, and the passport is ready to collect from the passport office 4 hours after the appointment. It can only be used to renew an adult passport.
• 1 week Fast Track service, £192 for an adult and £156.50 for a child, or £206 and £170.50 for the 54 page version. The earliest appointment is the next day after you apply, and the passport is couriered a week after the appointment. It covers renewals, changes of personal details, replacements for lost, stolen or damaged passports, and child passports.

Neither covers a first adult passport. There is more detail in the article on urgent services, including who is shut out of each one.

Before you apply

• Check both dates on the personal details page and confirm which rule bites first.
• Apply online rather than on paper unless you have a reason not to, since it is cheaper.
• Have a digital photograph that meets the published rules, because a rejected photograph is the most common self-inflicted delay.
• Send supporting documents promptly, since the clock starts when they arrive.
• Keep the old passport until the new one is in your hand, and expect it to be returned cancelled.
