Choose Heathrow Express for Paddington speed. Choose the Elizabeth line for more of London.
Heathrow Express is the fastest direct airport rail option to Paddington. The Elizabeth line takes longer to Paddington but continues directly through central and east London. If your hotel is near Bond Street, Tottenham Court Road, Farringdon, Liverpool Street or Canary Wharf, avoiding a second transfer can matter more than saving minutes on the airport leg.

1. If you are staying near Paddington, Heathrow Express is difficult to beat on speed
Heathrow currently publishes a 15-minute Heathrow Express journey from Terminals 2 and 3 to Paddington, with frequent direct trains. That is the headline advantage: a very fast, non-stop airport leg. If your hotel is in Paddington, Bayswater or close enough to walk or take a short taxi, there may be little reason to add another London interchange.
The important detail is price. A Standard single is currently £26, while advance discounted singles can start from £10 when booked 30+ days ahead. That means the simplistic advice that “Heathrow Express is always expensive” is not reliable. Booking lead time can change the comparison completely.
2. The Elizabeth line usually wins when your destination is beyond Paddington
TfL publishes a journey of about 28 minutes between Heathrow and Paddington. That is slower than Heathrow Express — but Paddington is not the end of the Elizabeth line. Direct trains continue through stops including Bond Street, Tottenham Court Road, Farringdon, Liverpool Street and Canary Wharf.
That matters because a 15-minute airport train followed by a Tube change, station walk and final connection can easily be less convenient than staying on one train for longer. Terminal2City therefore treats the final London address as more important than the fastest airport segment.
If Heathrow Express gets you to the correct side of London, choose it for speed. If it gets you to Paddington only to make you change again, compare the Elizabeth line all the way to the station closest to your hotel.
3. In 2026, the fare comparison is more nuanced than it looks
TfL states that from 1 March 2026 the adult pay-as-you-go fare for an Elizabeth line journey between Zone 1 and Heathrow is £15.50. You can use contactless or Oyster. There is no need to reserve a specific train.
Heathrow Express Standard is £26 for a single, but the operator sells advance discounted singles from £10 when booked 30 or more days ahead. So for an adult travelling to Paddington, an early Heathrow Express booking can actually undercut the Elizabeth line fare.
For a last-minute arrival, the Elizabeth line often has the simpler price/flexibility proposition. For a planned journey to Paddington, Heathrow Express deserves to be checked rather than automatically dismissed.
4. Families can get a very different answer
Heathrow Express currently allows children aged 15 and under to travel free in Standard Class with a paying adult. A ticket is still required for the child. That rule can make Heathrow Express surprisingly competitive for a family.
On TfL services, children under 11 can travel free on the Tube, DLR, London Overground and Elizabeth line when accompanied by a fare-paying adult, subject to TfL's rules. Visitors aged 11–15 can use a Young Visitor discount on Oyster for half adult-rate journeys. Contactless does not provide that child discount.
This is why Terminal2City now asks for adults, children aged 11–15 and children under 11 separately. “Four travellers” is not enough information to compare real family cost.
5. Which is easier with luggage?
Both are direct airport rail services to Paddington, so the airport leg itself is straightforward. The bigger luggage question is what happens after Paddington.
If your hotel is near Paddington, Heathrow Express can be exceptionally simple. If your hotel is near Farringdon or Liverpool Street, the Elizabeth line can avoid unloading bags, finding another platform, entering the Underground and handling another change. With two or three large suitcases, that difference often matters more than a few minutes of train time.
6. Which is safer after an uncertain flight arrival?
Flights are unpredictable. Passport control, baggage reclaim and walking through Heathrow can add substantial uncertainty to your actual station arrival time. Our Heathrow arrival-to-station time guide helps estimate that buffer before you choose a service.
The Elizabeth line works naturally as pay-as-you-go, so you are not tied to a particular booked departure. Heathrow Express also offers flexible ways to travel, but the conditions depend on the fare you purchase. If your priority is avoiding any anxiety about missing a booked train, always check the ticket conditions before choosing solely on price.
7. Do not accidentally board the wrong train
Heathrow Express and Elizabeth line both use Heathrow rail stations. Before boarding, check the departure display and train branding rather than assuming every central-London train is the one you intended to take.
If you planned to use the Elizabeth line, confirm the departure is an Elizabeth line service. If you bought Heathrow Express, follow the Heathrow Express signs and verify the train before boarding.
Which one should you choose?
You are going to Paddington or nearby, speed matters, or you found a strong advance fare. Families should also check it because children 15 and under currently travel free in Standard with a paying adult.
Your destination is near Bond Street, Tottenham Court Road, Farringdon, Liverpool Street, Canary Wharf or another location where staying on one train avoids a London interchange.
Your hotel is not close to the rail station and you have several large bags. A short final taxi can be easier than another Tube change without giving up the fast airport rail leg.
