Travel cost guide
Heathrow Express hits Paddington in 15 minutes for £26; the Elizabeth line takes about 30 for £13.90 direct across London; the Piccadilly line (Tube) is slowest but cheapest at £5.90. Which is worth it, and can you use one ticket on another?
In short: the Heathrow Express is the fastest, reaching London Paddington in 15 minutes, but at £26 for a walk-up single it is the most expensive. The Elizabeth line is the best all-rounder at about £13.90, taking around 30 to 45 minutes but running direct through central London with no changes. The Piccadilly line (Tube) is the cheapest at £5.90, but the slowest at 50 to 60 minutes. The Heathrow Express runs every 15 minutes from Terminals 2 & 3 and Terminal 5; advance tickets can drop to £10 if booked 30 or more days ahead. If your destination is not near Paddington, the '15 minute' time saving is often wiped out by the onward Tube or taxi journey across London.
Decision guide
The Elizabeth line is the modern all-rounder. While it takes longer than the Heathrow Express, it travels directly through the heart of central London. If you are staying near Bond Street, Tottenham Court Road, Farringdon, Liverpool Street or Canary Wharf, it can avoid a change at Paddington. Heathrow currently publishes Zone 1 journeys from £13.90 using contactless or Oyster; confirm the exact fare for your stations in TfL's Single Fare Finder.
The Piccadilly line is the budget choice at the current published contactless fare, but it is slower and uses standard Tube trains. Families and groups should compare the live total for each rail option with a written private-car quote rather than assuming one is cheaper. Heathrow Express advance tickets can be lower when booked well ahead, subject to the operator's current restrictions.

Practical checks
These checks keep the guide useful for real journeys rather than just repeating the headline fare or fastest advertised journey time.
Heathrow Express wins only when Paddington is genuinely convenient. If the final stop is Bond Street, Tottenham Court Road, Farringdon, Liverpool Street or Canary Wharf, the Elizabeth line often removes a second paid interchange.
One premium rail ticket can look acceptable. Three or four premium rail tickets can become more expensive than a fixed-fare car, especially after adding the taxi or Tube journey to reach Paddington.
Heathrow rail services split between terminal stations. Travellers should check whether they need Terminals 2 and 3, Terminal 4 or Terminal 5 before boarding, especially when luggage makes backtracking slow.

Traveller questions
These answers focus on the decision points that change the real cost, not just the advertised journey time.
No. The Heathrow Express and the Elizabeth line are separate services with separate tickets. A Heathrow Express ticket is not valid on the Elizabeth line, the Piccadilly line or any other Tube service, and vice versa.
No. They are different trains run by different operators. The Heathrow Express is a premium non-stop service to Paddington in 15 minutes; the Elizabeth line is a slower (about 30 minutes to Paddington) but cheaper service that continues directly through central London.
Heathrow currently publishes Elizabeth line journeys that start, end or pass through Zone 1 from £13.90. Pay with contactless or Oyster and check TfL’s Single Fare Finder for the exact stations and time.
To Paddington, yes — 15 minutes versus around 30 minutes. But door to door the Elizabeth line is often faster for central or east London because it avoids a change at Paddington, running direct to Bond Street, Tottenham Court Road, Farringdon, Liverpool Street and Canary Wharf.
The Piccadilly line is normally cheaper and Heathrow currently publishes an off-peak Zone 1 fare from £5.90. Heathrow Express publishes separate advance and walk-up fares and reaches Paddington in about 15 minutes. Check both operators for the date you travel.
Both serve Terminals 2 & 3 and Terminal 5 directly. For Terminal 4, take the Elizabeth line, which serves it directly, or change at Terminals 2 & 3 — check your terminal before boarding to avoid backtracking with luggage.
The Heathrow Express is worth it if speed to Paddington matters most and your destination is nearby — it is the fastest option at 15 minutes. At £26 walk-up it is the priciest, so for most travellers the Elizabeth line (about £13.90, around 30 minutes, direct through central London) is better value, and the Piccadilly line (£5.90) is best on a budget. Booking the Heathrow Express 30 or more days ahead from £10 makes it far more competitive.
Yes, you can tap in with contactless or Oyster on the Heathrow Express, but you are charged the full Heathrow Express fare (around £26), not a cheaper Tube fare. Oyster and contactless only give you the low fare on the Piccadilly line (£5.90) or the standard pay-as-you-go fare on the Elizabeth line (about £13.90).
The Heathrow Express takes 15 minutes from Heathrow Terminals 2 & 3 to London Paddington, or about 21 minutes from Terminal 5, running every 15 minutes. The Elizabeth line takes around 30 minutes to Paddington but continues directly into central London without a change.
