50th anniversary
On 5th July 2017, ACS celebrated the start of its 50th anniversary, making us the third oldest (and, possibly, the wisest) international school in the UK. Our history is marked by milestone campus openings, world-renowned programmes, and future-facing teaching. We are proud of our heritage and the people (including 26,000 alumni) who have helped establish us as a leading group of international schools – now educating 3,500 students from over 100 countries, at four campuses.


Decade one

From city to countryside
During the following years of rapid growth, ACS reached an important milestone. With more than half of our students being bussed into central London from South West London and Surrey, we decided it made sense to relocate out of the city centre and into the suburbs, opening new campuses in Cobham, Hillingdon and later Egham.
ACS Cobham opened in 1975, set in the magnificent 128-acres grounds of the historic Heywood Mansion. By 1988, a state-of-the-art boarding house had been added. In 1978, ACS Hillingdon was founded on the 11-acre site of the old Hillingdon Court School. As demand steadily increased for quality international education outside of central London, we opened ACS Egham in 1995 on the beautiful 20-acre Woodlee estate. ACS Egham is now the only school in the country to offer all IB programmes.

A landmark campus for Doha
Wanting to make our model of education available to more students around the world, we opened our first overseas campus in Doha in 2011, combining the philosophy and approach of our established UK schools with the local traditions, culture and history of Qatar. ACS Doha experienced meteoric growth taking it to capacity in under five years. As a result, we opened a new state-of-the-art campus in August 2020, which more than doubled our student capacity to 2,470. It’s part of our dedication to create a legacy in Qatar.
Never resting on our laurels, ACS continues to look forwards, and become a UK registered charity in 2018. Now we can really widen our commitment to inspire and make a difference.
