About Aldwickbury

Inspiring teaching and exceptional facilities, where pupils are free to find their greatness.

A very warm welcome to Aldwickbury.

I am delighted to welcome you to our website, which I trust will provide you with valuable insight into the life of our school. Here, you will find information about our exciting and extensive curriculum, our forward-thinking approach to education, and most importantly, a real flavour of what it means to be part of the Aldwickbury community.

It is a great privilege to lead such an outstanding school, supported by a team of highly skilled and dedicated staff who, every day, ignite a passion for learning in our pupils. In September 2025, we were proud to welcome both boys and girls into our school, as Aldwickbury began its new chapter as a co-educational preparatory school. This is a significant and positive step forward for us, ensuring that our values-driven, nurturing education is accessible to more families in the heart of Harpenden in Hertfordshire.

As a school, we remain firmly committed to respecting tradition while embracing innovation. Our aim is to deliver an education that prepares children for the modern world, underpinned by strong values and high expectations.

Pastoral care sits at the heart of everything we do. Every child is seen, celebrated and supported to be themselves, to try their best, to embrace challenge and above all, to be kind. We believe this nurturing and supportive environment is the key to helping children flourish both personally and academically.

Aldwickbury offers a truly holistic education, where academic ambition is balanced with a rich co-curricular programme. Our pupils enjoy exceptional opportunities across the arts, STEM, sport, music and drama, all within our beautiful and extensive grounds. Every child is encouraged to discover their passions, build confidence and grow as individuals.

The journey through Aldwickbury prepares pupils to leave at 13, ready to take the next step in their educational journey, equipped with the skills, resilience and character to thrive. Of the utmost importance to us, is that they leave not only well-prepared academically, but as good people, kind, respectful and grounded in strong values.

I believe Aldwickbury is a very special place. I warmly invite you to come to visit us, either at our next open morning or for a personal tour, so you can experience for yourself the vibrant, inclusive and happy community that makes our school unique.

I look forward to welcoming you.

Headmaster

Founded in 1948, Aldwickbury School has a proud tradition of delivering outstanding independent education in the heart of Harpenden in Hertfordshire. The school was established by Headmaster Kenneth Castle, who saw the potential of Aldwickbury Mansion as the ideal setting to bring his educational vision to life. Alongside his colleague, Brian Chidell, he purchased the property with the ambition of creating a school that offered exceptional opportunities for young learners. 

However, the roots of Aldwickbury stretch back even further. In 1937, Kenneth Castle acquired Lea House School, then a small school educating just 15 boys. A year later, Brian Chidell joined as a Junior Master before departing to study at the University of Oxford. During the Second World War, Castle served his country, leaving the running of the school in the capable hands of Miss Margery Topham. When he returned in 1945, he found a thriving school community, 60 pupils and a small but dedicated team, including a cook and housekeeper. 

When Aldwickbury Mansion came on the market, Castle seized the opportunity to move the school to a more expansive and inspiring setting. In the summer term of 1948, Aldwickbury School officially opened its doors, welcoming the 65 boys from Lea House to their new home. Set within 20 acres of beautiful grounds in Harpenden, the site offered the space and environment needed for pupils to explore, discover and thrive. 

Originally established as a boarding school, Aldwickbury has retained the spirit of that tradition with its longer school days and the option of flexi-boarding. Our extended days allow for a strong academic focus, alongside a rich extra-curricular programme that nurtures character, confidence and curiosity. Dedicated prep time from homework during the school day also means that pupils can enjoy their evenings at home, creating a healthy balance between learning and family life. 

Aldwickbury has always believed in a truly holistic education, one that balances academic ambition with care, character and opportunity. While we honour our heritage, we continue to look forward, evolving our curriculum and culture to meet the needs of a changing world. This includes our recent and exciting transition to becoming a fully co-educational school.  

Throughout our history, Aldwickbury has never shied away from innovating or adapting, and are excited about how our change to co-education will bring a new chapter to the school. 

In Aldwickbury School’s 75-year history there have only been five Headmasters and a brief history of each of their tenures can be found below:

Confidence to pursue the greatness he has discovered
