Brits planning to travel abroad this Easter have been warned not to make a crucial passport mistake which could leave them seriously out of pocket. Adult passport renewals currently cost £94.50 when applying online - in some circumstances this can soar.

Experts say people should be checking their passports immediately, to make sure they are still valid as the window for standard renewals is already beginning to tighten. With Easter Sunday falling on 5 April this year, travellers who have not yet checked their passports may already be close to the usual processing deadline for standard applications.

According to official government guidance, most UK passport applications are usually processed within three weeks or less, although travellers are advised to apply well before their trip whenever possible. A standard adult passport renewal currently costs £94.50 when applying online, while applications submitted using a paper form cost £107.

However, if you leave this too late, urgent processing services mean prices rise sharply. The government’s Premium one-day passport service, used for urgent adult renewals, now costs £222, more than twice the price of a standard online application.

Andrea Platania, travel expert at Transfeero, says the weeks leading up to Easter are a common moment when travellers suddenly realise their documents may need attention. It is then a race against time to make sure they can still travel.

He says: "Easter trips often creep up on people. Many families book their flights weeks or even months earlier, then only check their passports when they start preparing for the journey.”

According to Andrea, discovering a passport issue close to departure can quickly complicate travel plans. “Renewing a passport is normally straightforward if you give yourself enough time,” he says. “But when travellers realise just a few weeks before departure that their passport has expired or does not meet entry requirements, the situation becomes much more stressful.”

Because standard applications can take around three weeks to process, travellers who are planning to leave the UK around the Easter period may now be close to the point where urgent services become the only realistic option. Urgent passport services require travellers to attend an appointment at a passport office.

The Premium one-day service can provide a renewed passport within hours of the appointment, but the convenience comes at a significantly higher cost. Andrea says this situation is surprisingly common during busy travel periods.

“People often assume passport renewals can be sorted out quickly at the last minute,” he explains. “But if the departure date is already approaching, travellers may find themselves forced to use urgent services that cost far more than the standard application.”

He advises travellers to treat passport checks as one of the very first steps when planning any international trip. He said: " “When you start looking at flights and accommodation, that is the moment to check your passport. If it needs renewing, doing it early keeps the process simple and affordable.”

He also notes that some countries require passports to remain valid for several months beyond the date of travel, meaning a passport that appears valid may still not meet entry rules, warning: "That is another detail people often overlook. A passport might technically still be valid, but it may not meet the entry requirements of the country you are visiting.”

With Easter travel approaching quickly, Andrea says travellers who have not yet checked their passports should do so as soon as possible. "A quick check today can prevent a lot of stress later,” he says. “If your passport needs renewing, acting early helps you avoid both the pressure and the much higher cost of urgent processing.”
