Joanna Thomas, an actress, married her husband David, a Gurkha officer, in 1962. They lived in the Far East until David left the Army in 1969. In 1971 Joanna was given a main part in a serial on Granada TV, which took a year to complete. In order to help juggle finances to pay for their young children’s primary education and to be able to afford childcare for their youngest son, two year old Ben, Joanna set up a kindergarten in a local church hall in Pimlico.
Six years later, the success of the kindergarten and the strong demand for London day schools of quality encouraged David Thomas to give up his job with an American bank and to join his wife in founding a school for older children. Joanna and David sold their family home, moved with their three children into a two bedroom basement flat and, with the proceeds, took a short-term let on a building in Cadogan Gardens. After just three weeks and some intensive decorating, the first Thomas’s prep school opened its doors to eleven pupils and two teachers.
From the outset, Joanna and David were determined to create a school environment that achieved three key aims: high academic standards, an emphasis on the arts and plenty of sport, reflecting both their personal and professional interests.
In less than four years, and now known as ‘Thomas’s’, the school had more than 200 children. It expanded into two buildings in Cottesmore Gardens, just south of Kensington Gardens, to create Thomas’s Kensington.
The Preparatory School at Cadogan Gardens needed more space and the freehold was acquired for the former Sir Walter St John’s Grammar School in Battersea. The school, which became Thomas’s Battersea Prep School, moved to its extensive new premises and the leasehold buildings in Cadogan Gardens were sold.
With an increasing demand for places, the freehold was secured for the former Clapham County Girls’ School in Broomwood Road and the new Thomas’s Clapham opened.
Thomas’s Kindergarten, Battersea was started in the crypt of St Mary’s Church educating 45 children aged from two to four years old.
Thomas’s Schools Foundation (TSF) was launched at the Royal Albert Hall. The charity had two areas of focus: to identify, develop and support educational activities for children in local primary schools; and to provide funding for bursaries for children to attend a Thomas’s school.
Thomas’s Kensington was provided with its own dedicated Lower School facility through the acquisition of Lady Eden’s School in Victoria Road W8. The existing buildings in Cottesmore Gardens were refurbished and now house the Preparatory School.
Since 1894, this property has proudly overlooked South Park. Previously owned by the London Institute for the Chelsea College of Art and Design, located on Hugon Road, SW6. It was leased by Thomas’s in 2005 and underwent a complete refurbishment. In 2024, the lease was renewed for a further 25 years.
In 2007 the Principals established The CAIRN Trust as a UK registered educational charity dedicated to ensuring that children in rural Nepal are given the opportunity to gain an education.
The facilities of Thomas’s Kensington were further improved through the purchase of the buildings of the Prue Leith School of Cookery in St Albans Grove W8, then converted into a purpose built theatre, a gym and a dining room.
Discussions began in response to an approach from New King’s Primary School. These led to the establishment of Thomas’s Academy, a state-funded primary school on New King’s Road.
After 25 years taking school ski trips to the same small resort in Upper Austria, Thomas’s purchased a 70-bed hotel on the mountain to create Thomas’s Daheim, now the location of week-long residential trips for pupils and an extensive outdoor learning programme.
Thomas’s Schools Foundation and the CAIRN Trust merged to form Thomas’s Foundation, a charitable incorporated company which seeks to live out Thomas’s values in the world through three core projects: Foundation bursaries, community partnerships, and the CAIRN Trust.
Thomas’s acquired an educational site in Putney Vale, which became the home of the first Thomas’s Senior School for four years. The campus offered a broad range of high-quality facilities, including specialist Science laboratories, dedicated Art and Design & Technology departments, and extensive provision for Outdoor Education and Sport. The Putney Vale site has since closed, and the Senior School has been relocated to Richmond, where it now forms Thomas’s College.
Thomas’s took ownership of Atlantic House and Lytham House on St Albans Grove, Kensington, and the buildings underwent a full refurbishment. Upon completion, Thomas’s transitioned from its long-standing premises on Victoria Road and Cottesmore Gardens, which had served as educational sites since 1870. The school relocated to its new site in November 2025.
Thomas’s College, acquired in 2023, had a distinguished history as a nineteenth-century educational site. Originally founded as the Wesleyan Theological College, its main Grade II listed building opened in 1843. Situated on Richmond Hill, Queen’s Road, the five-acre campus featured landscaped gardens adjoining Richmond Park. More recently, it had been home to the American International University in London before reopening as a co-educational day and flexi-boarding senior school in September 2025. Thomas’s College is now home to pupils aged 11 to 18, providing a world-class education in exceptional surroundings.
November 2025, Thomas’s Kensington opened the doors to its new purpose-built school in St Albans Grove, W8, a landmark moment in the Thomas’s story. The light-filled building has been designed to inspire curiosity, creativity and connection, with specialist spaces for science, computer science, art, dance and music and thoughtfully designed outdoor areas that encourage play and exploration. Reflecting the kindness, breadth and excellence at the heart of a Thomas’s education, this exceptional new environment provides a fitting home for children to learn, grow and flourish for generations to come.
