They don't keep stocks of currencies apart from Euros and US Dollars, so you have to preorder in the morning to collect in the afternoon for anything else. They've always been quick and efficient whenever I've dealt with them, although sometimes there are queues during the lunchtime rush at the Canada Place store (there are two in the Canary Wharf mall). On one occasion they didn't get the delivery of the currency I wanted, but they said if I came back the next day, they'd give it to me at their wholesale price, which is more than fair.

The jerk Muhhamed which probably smells his crusty farts behind the glass booth added a 15% commission without consent and gave me a folded receipt. He acted like he was really helping us out and I dropped my guard...Im sure karma will get the best of him. Horrible first experience on dealing with a currency exchange company. When I pointed it out he said no refunds and pointed to a tiny sign at the corner of the counter that said there was a 15% commission but while I was in line I overheard him telling customers that they were not charging commission. I even found a receipt on the counter to point it out to him. The exchange rate was horrible too but I needed money. I emailed the company but no response. I figured there a heartless corporation takin advantage of first time travelers and elderly people.

I normally end up having to put up with the terrible rates at the airport, or just wait until I find a cash machine at my destination, and then get ready to pay the extra bank charges. Oops. But this time, for the first time ever I remembered to research the best rates online, order some money, and then go and pick it up. With one day to spare as well...(this must be what it's like to be a responsible adult...ish) Thomas Exchange had one of the best rates in London for Euros, and although they had a long queue, it was still worth the wait. Book your money online first to get the best rates (they give you slightly less money if you just turn up without ordering it in advance...)

Went to Korea spent nine of the currency went back to exchange back to sterling only to be told that one note was not real Now that's a puzzle as all the notes I had came from this shop and having spent none of the currency to be told that they be not e is not legal is outrageous. They point blank refused to exchange the note in question even though I had the receipt to prove where they came from. When I challenged that they must have a record of the serial number of notes they have and dispense to people they still refused to take the nite back. Trading standards here u come.

Each time, I was serviced with utmost professional personnel with also the best rate, almost bank rates. Of course, I bring good business to them to get these rates, but I have to say I would come back just because they make the entire process pleasant and easy. The good rates are certainly appreciated and significant, but certainly is a good on top of the already stellar services. I would highly recommend this place for foreign exchange needs, especially for ex-pat or short-term foreign studies!

This place has very good exchange rates and I use this company every time. The advantage of this branch is they have a high stock of the more obscure currencies and so I do not have to wait for them to get it in stock. I was served by Sudeep who was very helpful and most of all he pointed out when I thought I had given less money than I actually had. This of course is greatly increased my trust and makes me even more a regular customer. This branch is so good I actually travel to go to it.

They even advised whether my bank would charge me for the transaction using my debit card.

Here is where you should exchange your mula when in London town…read more I was in desperate need for some British pounds after stupidly withdrawing a bunch of euros (this is what happens when your head is still in the clouds after a ridiculously long and delayed flight, thank you United). After doing some quick research on the best places to exchange cash, I came across a few forums that mentioned Thomas Exchange. Luckily there was a branch a brisk 15 minute walk from where I was staying. I went there around mid-morning on a Tuesday and had no trouble finding it in a covered arcade. There were a few people in line, but it moved very quickly. The tellers were very quick in handling each person's request. I've seen banks in other countries where they would spend a good 30 minutes with each person, counting and recounting the cash, putting it through a counting machine, and then manually counting again. Thank goodness they didn't do this here or else I'd be waiting for half a day. Best of all the exchange rate was great, only off the market value by a few pennies. I'm writing this Yelp review to point others in the direction of Thomas Exchange, but also so that I can remember to come here next time I'm in London!
