Travel times from Central London to Heathrow
Heathrow Express Train (fastest, most predictable)
Paddington Station → Heathrow Terminal: 15-17 minutes, every 15 minutes, £11.50 single. Trains depart 05:12-23:42. This is the most reliable option — no traffic, no delays.
Add 10-15 minutes for getting to Paddington from your Central London location, plus 10 minutes in terminal.
Total time Soho to Heathrow T2: 40 minutes (30-minute buffer)
Underground Piccadilly Line (cheapest)
Central London → Heathrow Terminals 1,2,3 or Terminal 4: 40-50 minutes depending on starting point. Runs 24/7 but slower early morning (trains less frequent).
£1.75-3.20 depending on zones. Can be crowded during rush hour with luggage.
Licensed Taxi/Minicab (most predictable for luggage)
Moderate traffic (off-peak): 45-60 minutes from Zone 1. Cost: £40-65.
Heavy traffic (rush hour 7-9am, 4-6pm): 75-120 minutes. Cost: £65-100+.
A fixed-price chauffeur removes the surge pricing risk and guarantees arrival time with no guesswork about traffic.
Private Car (personal vehicle)
Parking at Heathrow: Long-stay parking averages £20-25 per day (book online to save). Travel time by car: same as taxi (45-120 minutes depending on traffic). You also add 5-10 minutes parking and walking.
London traffic patterns to Heathrow
Light traffic windows (45-50 min drive time):

- Midday 10:00 AM - 2:00 PM
- Sunday afternoons 2:00 PM - 6:00 PM

Heathrow security queue times
Off-peak security: 5-10 minutes (most weekday afternoons, early mornings)
Peak security: 15-25 minutes (6:00-9:00 AM weekdays, 2:00-6:00 PM)
Terminal differences: T2 and T5 average 5 minutes faster than T3 and T4.
Tip: If your flight departs before 9:00 AM, arrive 4 hours early, not 3. Early morning security can pile up quickly.
Early morning flights (06:00-08:00 departure)
These are tricky. Leave by 03:00-03:30 from Central London if driving. Heathrow Express first train departs Paddington at 05:12 — you'll need to leave your location by 04:45 to catch it.
For truly early flights, a minicab that you've booked the night before (with fixed time and price) is your safest bet. Trains may be less frequent; traffic is unpredictable; and you'll be stressed if you miss it.
