We were group of four with large size luggage. Both quotes & bookings are done via email. Once you receive a quote and are ready to pay there are several payment options offered. I used PayPal. Both pickups were easy. On day of pickup at LHR I got a text alert from Blackberry & the driver regarding where the car was and estimated arrival time. The driver met us at the suggested meeting place at LHR on time. Ditto Southampton cruise terminal pickup with a drop off at our London hotel. I'd booked with Blackberry if I'm ever in London again.

The drivers are awesome. They are really good conversationalists and helpful. You should read up about their test if you are not aware already. It seems impossible to pass! Sounds as hard as the grand sommelier test. Interesting tidbit I got on one of the trips on this visit. Turns out Sylvester Stallone had ridden the cab and was super nice and gracious. Loved hearing that!

They are identified by their license number in the upper left corner of their car. It is safe and reliable. The fare is clearly posted in the cab, no surprises. The drivers are knowledgeable and helpful Unlike Uber, you know who is driving if you need to. Uber can be anyone . Research is key when traveling as you want to be safe before you get in the car, in a strange city ! Support the hard work of these can drivers ! Uber May be cheaper, but you get peace of mind in a black cab!

Coming back today with the M4 closure the driver took a circuitous route which avoided all the main detours and got us back much more quickly than we thought. Excellent.

They offer a Eurostar Cafe onboard where we ordered water and chips. The cashier was friendly and offered us French mini chocolates, which we graciously took. At the cafe we purchased subway passes for Paris called Navigo. Much easier process than flying.

I have used this company lots over the past few years and they are always prompt, friendly and know exactly where they should be going. I know that should always be the case with taxis but in London it's a rare thing when it comes to mini cabs. Even when other companies have quoted me an hour to get to me these fellas have said 'no problem' and been there in 10 minutes. At the London Field Day festival, they helped me and my friend get home for a snip of the cost of the other places near Victoria Park and we only wait about 15 minutes. They are good if you are a single female traveling too. Thank you Diamond Taxis - you are my favorite!

To be fair, they are good for local pick ups and drop offs. and actually good for going to airports. but their problem is the pick up from the airport plus the very arrogant attitude of some drivers, one of them definitely had some anger issue! Last week I booked a cab from abroad to be picked up from heathrow. when I arrive at the baggage reclaim, the cab driver calls me and says that he is going to take another 30 mins. I'm actually a patient person so I just said ok. I go out to the arrival and call the driver after 30 mins, he said that he will be late for another 5-6mins, and tells me to come to the 'drop off' area, which I had no idea where it was. I asked around dragging my suitcase, but no one seemed to know, so I waited outside the arrival near the taxi area for another 15 mins. still no sign of my cab turns out that the driver didn't have any credit on his phone and couldn't call me. very professional. I found out that he was on the departure level drop off. I had to go 3 floors up, he is still not there, takes him another 5 mins to appear in front of me. He did apologies but the tone of his voice is not especially sorry and just made excuses rather angrily. His driving was dangerous, rough and speeding way to fast. I expected some sort of discount, as I waited almost 1 HOUR after an 13 hour flight and used my mobile to call the driver about 5 times. but he refuses to give any discount. I called the office and they spoke to the driver, tells him to give me 2 POUNDS off. I thought they were joking but they were dead serious. I lost my energy to argue and just paid him 45 pounds that he did not deserve. When I turned away, I could hear him saying something rude to me. very disappointing as a loyal customer NEVER EVER AGAIN.
