New UK Passport Rules: What Dual Citizens Need to Know! (2026)

The UK government has announced significant changes to its passport regulations, which are aimed at enhancing national security but may lead to complications for dual citizens.

Scheduled to take effect soon, these new rules state that individuals holding both British and Irish citizenship will no longer be able to enter the UK using their Irish passports unless they apply for a Certificate of Entitlement (COE) or possess a valid British passport. This change, revealed in November, is designed to tighten border security, reflecting similar measures adopted by many other nations around the world.

As an illustration, Australian citizens who also hold British nationality will now face specific requirements: they must travel with either a British or Irish passport, which costs approximately $190, or obtain a COE priced at around $1,100. Alternatively, they could renounce their British citizenship and use their Australian passports alongside an approved electronic travel authorization (ETA), which is a much cheaper option at roughly $32.

Many have voiced their concerns; the ABC has received feedback from hundreds of individuals feeling bewildered and frustrated due to these upcoming changes, which jeopardize their short-term travel plans.

In response to inquiries from the ABC, the British High Commission in Australia defended the new measures, stating that they align with the UK's aim to develop a more efficient, digital immigration system that enhances both speed and security for the millions traveling through UK borders annually. The introduction of ETAs, they noted, plays a crucial role in preventing the entry of individuals deemed a threat to the UK’s safety.

An ETA will only be necessary for travelers from 85 visa-exempt countries, including Australia, who do not hold British or Irish citizenship. Additionally, the new regulations will affect children born abroad who are dual citizens by descent. These children, even if they have never held a British passport before, will now require either a British passport or a COE prior to traveling to the UK. The British High Commission clarified that this requirement reflects an update in border processing rather than a change in citizenship status.

Starting February 26, COEs will be issued electronically and will need to be paid for only once. Once registered, these certificates will be permanently linked to the applicant's online UK Visas and Immigration (UKVI) account.

With the announcement coming just three months before enforcement, many Australians with pre-booked trips to the UK have expressed anxiety about the limited time available to secure new British passports, leaving them with the potentially much more expensive COE option. Current passport processing times remain at three to six weeks, while COE applications can be completed online but require an appointment at a visa application center, available in all Australian capital cities except Darwin, and may take up to three weeks to finalize.

For those who urgently need to return to the UK but are unable to renew or replace their passports in time, the British High Commission pointed out the existing Emergency Travel Document (ETD) provision. To qualify for an ETD, applicants must meet certain criteria, including being a British national, currently outside the UK, needing to travel within six weeks, and having a UK passport that is lost, stolen, damaged, full, or expired. Importantly, applicants must have previously held a valid UK passport issued after January 1, 2006.

In exceptional cases, such as emergencies related to funerals or unforeseen births, individuals who have never held a UK passport issued after this date may still be eligible for an ETD. However, general holiday travel or weddings do not meet the criteria for urgent travel.

ETDs are valid for either a one-way journey or a return trip and permit transit through a maximum of five countries. The UK already had provisions for ETDs applicable under the aforementioned circumstances, and these allowances have not changed despite the new passport rules.

As the enforcement date approaches, Australian nationals with dual citizenship should double-check their passport status to ensure they possess either a valid British passport or a COE. Those traveling solely on an Australian passport must apply for an ETA at least three days before their departure. This digital travel permit must be obtained prior to flying to the UK, as it is not issued upon arrival.

Typically, British citizenship is automatically transferred to children born outside the UK if one parent is a citizen when the child is born. For travelers unsure of their citizenship status, they can verify their British nationality through official channels. If dual British citizens cannot produce valid documentation, they will face additional identity checks at UK passport control, which may delay their boarding. The British High Commission has firmly rejected claims that these passport changes are merely a financial scheme, emphasizing that the UK government does not profit from the associated fees.

Census data shows that just over 2% of the UK's 70 million residents possess passports from multiple countries.
