The guide accompanies you on the way to the entrance of Buckingham Palace and provides information about the British royal family via wireless headphones. You will then be let in at an entrance without a queue and from there you can move freely with an audio guide. The guide spoke very quickly.

Absolutely very good guide, a man with his own English style, I don't remember if he said his name, in case I forgot it. We walked fairly quickly and he explained the story well. The only flaw why I can not put 5 stars is that I had selected Italian language but instead spoke English and unfortunately my mother does not speak even a word so she did not understand anything, you could equip yourself with some means that translate in real time into your own language what is said.

Visiting Buckingham Palace itself was really great. There was an audio guide that revealed important information about individual rooms. At the end of the tour there was even a Buckingham Palace café which was located in the back part of the garden, from which one could enjoy the beautiful view of the countryside. The prices here were also okay. The reason why I gave this tour a star deduction is that the described tour, which you do together with City Wonders over the Mall to Buckingham Palace before entering the palace, is not particularly spectacular. It is about half an hour and information about the Royal Family. It was interesting to hear but not worth the price as the actual ticket into Buckingham Palace is only around £25 and the rest of the cost is for the walking tour beforehand.
