UK ETA for Families 2026 — Parent and Child FAQ

ETA family travellers guidance for parents planning a family trip continues to evolve in 2026, and this guide pulls together everything British travellers, families and first-time visitors need before they fly. Notably, the ETA family travellers situation looks deceptively simple at first glance, yet small details around fees, validity, transport and timing can change a smooth trip into a stressful one. Notably, we have built this article around what the Home Office, gov.uk and Transport for London actually publish, rather than around hearsay you may find on social media. Conversely, you will find practical price comparisons, official quotation links, and a frequently asked questions section answering the queries our readers send in most often.

Consequently, the United Kingdom welcomes more than 32 million international visitors a year, and the ETA family travellers framework was designed to keep that volume moving while sharpening pre-arrival checks. Importantly, the system has now stabilised, with the £20 fee, the two-year validity, and the six-month maximum stay forming the backbone of every traveller’s plan. Conversely, we will walk through each layer of the journey – from arrival logistics to bank-holiday timing, from family rules to budget tactics – so that nothing surprises you on the way to passport control.

One ETA Per Person

Crucially, the United Kingdom requires a separate £20 ETA for every traveller, regardless of age. By contrast, a family of four therefore pays £64 in fees.

Indeed, ETA family travellers cannot pay one fee and cover the household. Moreover, the Home Office page repeats this point in the second paragraph of the official guidance.

How a Parent Applies for a Child

Furthermore, the official ETA app asks the adult applying to declare a relationship to the minor. Notably, the parent provides the child’s biometric passport, photo and parental contact email.

However, guardians who are not the legal parent should carry a notarised letter of authority and the parent’s contact details for border officers.

Family Payment Tactics

Moreover, four ETAs at £64 in total is well within most credit card limits. In addition, apply with one card to keep statement reconciliation simple.

Furthermore, the ETA family travellers card receipt becomes a useful expense record. By contrast, our UK SIM comparison keeps app traffic free of roaming surprises.

Decision time	Up to 3 working days	Most decisions within minutes
Refusal appeal	None direct	Re-apply or apply for visit visa

Babies and Toddlers

Notably, babies in arms still need an ETA. Consequently, the photo requirement is relaxed – plain background close-ups taken at home are accepted.

Importantly, airline check-in confirms an under-two infant ticket; some airlines allow lap-infant on long-haul. Consequently, bring the child’s birth certificate for occasional border secondary checks.

Teens and Independent Travel

In addition, teens under eighteen flying alone require a parental letter on top of the ETA. Indeed, airlines offer Unaccompanied Minor services up to age sixteen.

Subsequently, eGate access is available from age ten with an accompanying adult, twelve solo at most UK airports.

Grandparents and Mixed Citizenship Households

Therefore, grandparents over seventy-five do not get a discount – the £20 fee is flat. Subsequently, dual nationals should apply with the passport they will fly on; see our UK ETA dual nationality rules guide.

By contrast, mixed-citizen families should apply early; refusal of one ETA does not affect the others.

Adopted Children and Step-Parents

Indeed, adopted children apply on their own passport. Consequently, carry adoption papers in case of secondary screening at border.

Importantly, a step-parent travelling with a step-child without the biological parent should have written consent and a copy of the marriage certificate.

Common Family Mistakes

Importantly, typing the parent’s passport number into the child’s application is the most frequent mistake. Above all, the family check-in chaos amplifies these errors.

Conversely, applying too late – within forty-eight hours of flying – is the second-biggest. By contrast, aim for at least seven days advance for a family of four.

On the Day at the UK Border

Consequently, families queue at staffed booths or eGates depending on age. Equally, the eGate accepts tween-and-up travellers; younger children must use a staffed booth.

By contrast, have boarding passes printed in case airport Wi-Fi struggles. Furthermore, our May bank-holidays guide flags peak-day arrivals.

Group Family Bookings, Sibling Logistics and Special Needs

Equally, families travelling with three or more children benefit from preparing a master spreadsheet showing each child’s passport number, ETA reference and approval date. Moreover, this single sheet saves panic at airline check-in.

Equally, special-needs travellers can request priority lanes at most major UK airports. Conversely, the airline must be informed at booking; the airport hidden-disabilities lanyard programme is widely respected.

Equally, sibling separations during eGate scanning are common: under-tens cannot use eGates, while siblings over ten can. Conversely, families should consequently use staffed lanes together for younger groups. Importantly, our ETA family travellers editor recommends downloading the airline app the day before so that boarding passes auto-update if check-in needs to split family seats.

Emergency Contacts and Health Service Access

Moreover, the universal emergency number in the UK is 999 (or 112 from a mobile). Moreover, non-urgent NHS guidance is available at 111, twenty-four hours a day, with translators on demand. Crucially, all 999 calls are recorded; speak clearly and provide a postcode if known.

However, the British Red Cross runs travel-companion advice for elderly UK arrivals at no cost. Moreover, embassies remain the first port of call for lost passports. Subsequently, your home embassy in London usually issues an emergency travel document within forty-eight hours, while a UK police lost-property report takes around fifteen minutes.

Equally, stash printed copies of your travel insurance, ETA approval and passport bio page in a separate pocket from the originals. In addition, our ETA family travellers preparation list reminds you to register the trip with your home government if a remote emergency could affect family communication.

Money, Cards and Currency Conversion Strategy

As a result, the United Kingdom remains a card-first country in 2026, with even small market stalls accepting contactless. Consequently, the smartest combination for a ETA family travellers traveller is a Wise multi-currency card paired with a backup Mastercard or Visa from your home bank.

Therefore, ATMs charge no fee on most major UK networks; private convenience-store machines sometimes add a £2 surcharge, displayed before withdrawal. Conversely, currency-conversion-on-card prompts are a trap – choose ‘pay in pounds’ rather than the airline conversion to home currency.

Furthermore, mobile payment via Apple Pay or Google Pay works seamlessly on the Tube, buses and most retailers. However, set a transaction limit of £45 in your banking app to deflect occasional skimmers. Furthermore, our ETA family travellers packing tips also mention keeping a little cash for traditional pubs that occasionally still display ‘cash only’ signs.

UK ETA for Foster Children, Adopted Minors, and Special Cases

Furthermore, the UK Home Office requires careful documentation for non-traditional family arrangements. Indeed, adopted children apply on their own passport but must carry adoption papers for border verification.

Moreover, foster carers travelling with foster children need a notarised letter from the placing authority. As a result, expect questions at border control and have all documents accessible.

Subsequently, special-needs children may require additional medical documentation. Crucially, the ETA application asks generic medical questions; specific conditions should be disclosed only when asked. Above all, the £20 fee is the same across all family arrangements.

ETA Family Edge Cases – Babies Born Abroad and Mid-Trip

Furthermore, families occasionally welcome a new baby while travelling abroad. Indeed, a child born outside the UK still needs an ETA before flying to the United Kingdom.

Moreover, the home country consulate issues an emergency birth certificate; the parents then apply for an emergency child passport, then submit the ETA online.

Subsequently, the timeline can be tight – three days for the passport plus three days for the ETA approval. As a result, plan ahead for any UK leg planned within two weeks of the due date.

Crucially, dual-national newborns inherit the parents passport rights; in those cases the British passport route avoids the ETA entirely.

Above all, our editor reminds families that the £16 fee applies to babies as it does to grandparents – there is no infant exemption.
