Heathrow passport control: eGates, the UK ETA, and arrival waits

Three things matter at the UK border, in this order. First, a valid passport: machine-readable for the staffed desks and biometric (with the chip symbol on the cover) for the eGates. Second, permission to be in the UK. That is one of: British citizenship, Irish citizenship, an existing UK visa or settled status, an eVisa held in your UK Visas and Immigration account, or an approved Electronic Travel Authorisation (an ETA) if your nationality requires one. Third, the willingness to answer the standard Border Force questions about the purpose of your trip, where you are staying, and when you intend to leave.

Border Force is a UK Home Office agency, not part of Heathrow. The staff in the dark blue uniforms at the desks and around the eGates are Home Office officers; the airport runs the queue management and the live data feeds, but the decision to let you in is the officer's. An approved ETA, like a visa, authorises you to travel to the UK but does not by itself permit entry; the officer (or the eGate) still makes the final call.

For most arrivals at Heathrow the actual experience is short and procedural: choose the right queue, scan your passport, answer a question or two if asked, walk through to baggage reclaim. The detail below covers each step in turn.

Who needs an ETA

You need an ETA to enter the UK from 25 February 2026 onwards if your nationality is on the visa-free list (around 85 countries). That covers the United States, Canada, Australia, New Zealand, Japan, South Korea, all 27 European Union member states, the wider European Economic Area (Iceland, Liechtenstein, Norway), Switzerland, the Gulf states (United Arab Emirates, Saudi Arabia, Qatar, Bahrain, Kuwait, Oman), and a long tail of others. The authoritative list is at gov.uk/eta. If your nationality is not on the list, your trip needs a visa rather than an ETA; the gov.uk eligibility checker tells you which.

Several groups do not need an ETA. British and Irish citizens never need one, regardless of any other passports they hold. Anyone with existing UK immigration permission (a visa, settled or pre-settled status under the EU Settlement Scheme, or an eVisa) does not need one. Legal residents of Ireland travelling within the Common Travel Area do not need one if they can show proof of residency. Holders of British Nationals Overseas and British Overseas Territories passports do not need one.

Cost and validity

The ETA fee is £20, paid once. It rose from £16 on 8 April 2026. The authorisation is valid for two years or until your passport expires, whichever is sooner, and permits multiple journeys to the UK with stays of up to six months at a time. There is no separate longer-validity or longer-stay tier; you renew when it expires or when you get a new passport.

How to apply

The official application route is the UK ETA app (available on the App Store and Google Play) or the gov.uk/eta web form. Decisions usually come back within minutes; the Home Office advises allowing up to three working days. You apply with the passport you intend to travel on and pay by card. Third-party visa services charge a markup on top of the £20 fee for what is effectively a self-service application; use gov.uk or the official app directly.

If you hold more than one passport

Apply for the ETA on the passport you will actually travel on, and use the same passport at check-in, at boarding, and at the UK border. Dual British or Irish citizens should travel on their British or Irish passport, not on their other one; presenting only the non-British passport will get you denied boarding. If you have travelled in and out of the UK before on a different passport, the ETA is tied to the new passport, not the old one.

If your ETA is refused

A refused ETA means you cannot travel to the UK on the visa-free route; you would need to apply for a visa instead. The gov.uk page explains the visa options. Common reasons for refusal are a criminal record, previous immigration breaches, or incomplete information on the application. The fee is non-refundable.

Eligible nationalities

The eGates are open to passport holders from: the United Kingdom, all 27 European Union member states, Australia, Canada, Iceland, Japan, Liechtenstein, New Zealand, Norway, Singapore, South Korea, Switzerland, and the United States. Members of the Registered Traveller Service from other nationalities are also eligible (a small subscription-only scheme; most travellers do not use it). Anyone outside this list uses the staffed desks.

Passport requirements

Your passport must have a biometric chip (most issued from 2010 onwards do; the chip symbol on the cover is the visual cue). Damaged passports, emergency travel documents, and some replacement documents do not work in the eGates and you will be directed to the staffed lane.

Age rules in 2026 and the change coming in July

The minimum age to use the eGates is currently 10. Children aged 10 to 17 must be accompanied by an adult who is also using the eGate; unaccompanied under-18s cannot use eGates.

From 8 July 2026, the minimum age drops to 8. Children aged 8 or 9 must be at least 120cm tall and accompanied by an adult. The change was announced by the Home Office on 14 May 2026 and applies across more than 290 eGates at UK airports plus the juxtaposed ports at Brussels and Paris where UK Border Force operates ahead of Eurostar departures.

What happens at the gate

You approach the eGate with your passport open at the photo page, place it on the reader, look at the camera, and walk through when the barrier opens. The gate reads the chip, takes a live photo, and matches the two. If both pass you are through. If either fails the gate refuses and directs you to a staffed desk; the staff at that point are Border Force officers, not airport employees. There is no charge to use the eGate. There is no need to fill in a landing card; the UK abolished them in 2019 for most international arrivals.

If your nationality is not on the eGate list, if your passport does not have a chip, or if the eGate refuses you, you use the staffed desks. The officer scans your passport, may ask you a small set of questions about the purpose of your visit, where you are staying, and when you intend to leave, and either admits you (with an entry stamp if relevant) or refers you to a second-line officer for more questions.

The standard questions are conversational. Be ready with the address you are staying at (the hotel name and rough area is fine), the rough length of stay, and an idea of what you are doing in the UK. Officers can ask to see your return ticket, accommodation booking, or proof of funds; in practice most arrivals at Heathrow are admitted in under a minute at the desk. If you are refused entry, you have the right to ask the reason in writing and to contact your country's consulate; the Border Force will explain the next steps.

Children aged 10 to 17 use the eGates only if accompanied by an adult who is also using one. From 8 July 2026, children aged 8 or 9 join under the same accompanied-by-adult rule, with the additional 120cm height requirement. Under-8s use the staffed desks regardless of nationality.

At the staffed desks, the officer may ask to see documents confirming a child's relationship to the adult travelling with them. This applies in two common situations: a child travelling with one parent rather than both, and a child with a different surname to the parent or guardian. The recommended documents are the child's birth certificate showing both parents (or an adoption certificate), a letter of consent from the absent parent with their contact details, or any relevant court order. This is standard practice and not a signal of suspicion; the documents make the desk faster, not slower.

For unaccompanied minors travelling alone, the airline handles them through a separate process and they go through the staffed desks regardless of age.

The UK has moved fully from physical immigration documents to eVisas. Biometric Residence Permits (BRPs), Biometric Residence Cards (BRCs), the paper visa vignettes stuck into passports, and the old ink-stamp endorsements have all been phased out. From 25 February 2026, UK Visas and Immigration stopped issuing physical visa vignettes and BRPs entirely; BRPs in circulation expired by 31 December 2024, with a grace period that ended in June 2025.

If you have UK immigration permission (a work visa, study visa, settled or pre-settled status, indefinite leave to remain), you now access your status through a UK Visas and Immigration account at gov.uk/eVisa. The account is free to create and links to the passport you travel on; airlines and Border Force check it through the View and Prove service.

Without a UKVI account linked to the passport you are travelling on, you risk being denied boarding even if you legally hold UK immigration permission. Create the account before you travel.

Heathrow offers a paid Fast Track Arrivals lane through passport control. The fee is £25 off-peak and £35 peak per passenger, payable in advance through heathrow.com. The lane is available at all four terminals (Terminal 2, Terminal 3, Terminal 4, and Terminal 5) and bookable in hourly arrival windows from 06:00 through 21:00, subject to operational availability.

Fast Track Arrivals is open to any passenger regardless of airline or cabin class; you do not need to be flying in business class or with a particular carrier. It is the only paid way to skip the queue at the staffed desks. eGate-eligible passengers usually do not need it because the eGate queue is faster than the manual queue at most times, even before the Fast Track lane is taken into account.

Fast Track Arrivals (passport control) is a different product from Fast Track Security (departures, from around £12.99 per person), which speeds you through the security search before your flight, not after landing. The arrivals product launched in July 2025; the departures security product has been around for longer.

Heathrow and Border Force publish a Service Level Agreement for queue times at passport control: 95% of European Economic Area and eGate-eligible passengers cleared within 25 minutes, and 95% of non-EEA passengers within 45 minutes. The measurement is taken every 15 minutes at each terminal by an independent team and published in Heathrow's monthly Border Force performance reports.

The realistic peak windows at Heathrow are the morning long-haul arrivals bank between 06:00 and 09:00, and the afternoon-to-evening international bank between 13:00 and 21:00. Wait times in those windows often run at the upper end of the SLA range. The quietest stretch is typically late morning into early afternoon.

Performance depends more on Border Force staffing decisions than on the airport itself. Heathrow runs the queue layout, the eGate hardware, and the screens; Border Force allocates officers to desks. If staffing is light against an arrival bank, the wait will be longer regardless of how well the airport is performing operationally.

Wait times also vary by terminal because each terminal has its own arrivals hall and its own bank of eGates. Heathrow has the UK's largest deployment of eGates (more than 290 across the country in total), with the largest single bank at Terminal 5 to handle the British Airways long-haul arrivals peak. For a current view rather than typical patterns, the live arrivals board at heathrow.com tells you what is landing now; published live wait times are not part of the data feed.

If your connecting flight at Heathrow is on a single booking and your bags are checked through to your final destination, you may not need to clear UK passport control at all. International-to-international airside connections stay inside the international transit area and skip both immigration and customs.

You will need to clear UK passport control if your two flights are on separate bookings, your bags are not through-checked, you are leaving the airport landside, you are changing terminals between flights, or your route requires it. The most common unexpected clearance is a connection where the airline cannot through-check the bag because the second carrier does not have an agreement with the first.

As of January 2025, a temporary exemption removes the ETA requirement for genuine airside-only transit passengers who do not cross the UK border. The exemption is still in force in May 2026, but the Home Office labels it subject to review; check the gov.uk eligibility page before booking if you are visa-exempt and only transiting.
