The third-in-line to the throne George, eight, is in year four, while his younger sister Charlotte, six, is in year two at the co-educational independent preparatory school which has the ethos of ‘be kind’.
However the young royals are not known by the royal titles at school and have the surname of Cambridge as a nod to their parents the Duke and Duchess of Cambridge.
It comes after Prince William and his brother Prince Harry were known as William and Harry Wales to pay tribute to their parents the Prince and Princess of Wales.

Prince George’s fees at the school are believed to be £7,810 per term because he is the eldest child and in year four while Princess Charlotte’s fees total are thought to be £6,810 because she is the second child and in year two.
There are three terms at Thomas’s Battersea, which include Michaelmas, Lent and Summer meaning George and Charlotte’s school fees per school year are understood to total £43,860.
Meanwhile when Prince William’s father Prince Charles eventually rises up the ranks to become King, he will have to let go of his title of Prince of Wales.
It’s likely that as William becomes heir to the throne, his 73 year old dad will pass on the title to him, which would make his wife Kate the Princess of Wales.
The last person to hold that title was William’s mother Princess Diana, who died 25 years ago in a car crash in Paris, France.
Out of use for over two decades, a source has explained that it will be a “bittersweet” moment for William if they do inherit the titles of Prince and Princess of Wales.
A source told The Telegraph: “I’m sure it’ll be a bit of a bittersweet moment. This is her [Diana’s] son and his wife, so in some ways it will be coming full circle – but it will also be a poignant reminder of what we all lost.”
It comes as Kate is said to have taken note of the Queen’s tactics since being promoted to Dame Grand Cross.
In 2019, the Kate was promoted by Her Majesty for her services to the sovereign and she is now the highest female rank in the Royal Victorian Order.
A royal source has made it known that over the years, Kate has “observed” Her Majesty’s “game plan” and “taken a lot” from her role model along the way.
