Hey! Just to add to what John has said, I’ve used the Heathrow taxis a few times myself. Overall, I’d say they’re decent but not always the best value. The drivers have generally been friendly and professional, but I’ve encountered a few who seemed a bit rushed or not as chatty as I’d hoped. The fares can definitely add up, especially if you’re going to a busy area like Covent Garden or Shoreditch.
If you’re considering other options, the Heathrow Express is fantastic for speed, but keep an eye on peak times when it might be more crowded. The Tube is a solid choice for a budget-friendly ride, just be prepared for a bit of a trek with luggage and the hustle of the city.
For a more predictable experience, I’d also recommend looking into airport transfer services where you book in advance. Sometimes they have good deals, and you can avoid the airport taxi queues. Uber is another good shout—often cheaper and you can see the price before you book.
Hope that helps and enjoy your time in London!
