Short answer: the Underground is the cheapest at around £5.50 and takes just under an hour. The Elizabeth line is the best balance at £13.90 and under 45 minutes. Heathrow Express is the fastest at 15 minutes to Paddington from £10 booked in advance. A black cab is £70 to £120 and takes 30 to 60 minutes.
Which of those is right depends almost entirely on your luggage, your arrival time and where in London you are actually going. Below is each option with what it costs, how long it takes and where you board. Checked August 2026.
Every option, priced
| Option | Cost | Time | Arrives at |
|---|---|---|---|
| London Underground, Piccadilly line | from £5.50 | under 1 hour | Straight into central London, many stops |
| Elizabeth line | £13.90 to zone 1 | under 45 min | Paddington, Bond Street, Tottenham Court Road, Liverpool Street |
| Heathrow Express | from £10 booked in advance | 15 min | Paddington only |
| Black cab | £70–£120 | 30–60 min | Your door |
| Pre-booked transfer | Agreed in advance | 30–60 min | Your door |
Heathrow’s own advice on the road option is worth taking seriously: allow at least an hour to get from Heathrow to central London by car. The 30-minute end of the taxi range is a clear road at an unusual hour, not a plan.
The train nobody talks about is usually the right one
Heathrow Express gets the advertising and the Piccadilly line gets the price, but the Elizabeth line beats both for most travellers.
It costs £13.90 to zone 1, takes under 45 minutes, and — the part that matters — it does not stop at Paddington and leave you there. It runs straight across central London through Bond Street, Tottenham Court Road, Farringdon and Liverpool Street. If your hotel is anywhere near that spine, you step off at your destination rather than transferring with your bags at Paddington.
Heathrow Express is genuinely 15 minutes and genuinely faster. But it only goes to Paddington. Unless Paddington is where you want to be, the journey does not end when the train stops, and the saved time frequently evaporates in the transfer.
The Piccadilly line is the cheapest by a wide margin and perfectly civilised at a quiet hour with one bag. With three suitcases at 5pm it is a bad idea, and there are stairs.
Compare pre-booked transfer prices
A fixed price agreed before you fly, with the driver meeting you in arrivals. Compare it against the £70–£120 metered range rather than against the train fares.

The taxi option, and what gets added
Black cabs wait at the ranks outside every terminal. TfL publishes the Heathrow to central London fare as £70 to £120 across all three tariffs, taking 30 to 60 minutes.
What can be added is short: £1.60 for a journey starting at an airport rank, and the Christmas surcharge of £4.00 if you land in that window. Nothing for luggage, nothing for extra passengers, nothing for paying by card.
One rule specific to Heathrow: a driver may normally refuse a journey over 12 miles, but from Heathrow that limit rises to 20 miles. So a cab from the airport is obliged to take you considerably further than one hailed in town.
If someone is collecting you by car, the terminal drop-off charge is £7 per entry as of 1 January 2026, with a 10-minute maximum stay. It must be paid by midnight the following day; miss it and it becomes an £80 parking charge, reduced to £40 if paid within 14 days. Blue Badge holders get a 100% discount but must register.
Choose by your actual situation
| If you are… | Take |
|---|---|
| Alone, one bag, daytime, going anywhere central | Elizabeth line |
| On a tight budget with time to spare | Piccadilly line |
| Going to Paddington, or in a genuine hurry | Heathrow Express |
| Two adults, several bags, late arrival | Pre-booked transfer or black cab — the per-head maths turns |
| Travelling with small children | Pre-booked transfer. The train is cheaper and the taxi is calmer |
| Using a wheelchair | Black cab. Every London taxi is accessible and the meter must not start until you and your aids are secured |
| Landing after midnight | Taxi or transfer — the Piccadilly line runs a night service on Fridays and Saturdays only |
The tipping point for a group is roughly three people. Below that the train usually wins on cost. Above it, a single fixed fare split between everyone is often cheaper than four rail tickets and always easier with luggage.
What to avoid
Anyone who approaches you inside the terminal offering a ride. A private hire vehicle in London must be pre-booked through a licensed operator — it cannot legally pick you up on the spot, and it cannot use the taxi rank. Touting is a criminal offence, and TfL’s own position is that unbooked minicabs are uninsured to carry passengers.
The legitimate options are: the marked taxi rank outside your terminal, a car you booked in advance whose confirmation shows the registration and driver, or the trains. Nothing else.

Rail fares and journey times are Heathrow Airport’s own published figures. Taxi fares, the airport rank extra and the 20-mile compellable distance are from TfL’s taxi fare card effective 25 April 2026 and the London taxi driver handbook. The terminal drop-off charge and its penalties are from Heathrow’s published terms, effective 1 January 2026. Last verified August 2026 — rail fares in particular change annually, so treat these as the current published figures rather than a guarantee.
