The school offers full, weekly and flexi-boarding. Boarding has become increasingly popular, especially for those children who will go on to board at their senior school. When there is space, flexi boarding is available, however boarding numbers are very high and parents should book well in advance.

John and Sarah Warlow are the housemaster and housemistress and run the boarding house with Murphy (the labrador), Sam (the toddler) and new addition, Jessica. They are supported by other teaching staff who have contact with the boarders during the day as well as during the evenings. This means that care is consistent and continuous. The welfare of the boarders is a priority and the school recognises that all the pupils are individuals and have their own personalities and needs. The school strives to meet these needs to make the pupils feel happy and special.
The refurbishment of the boarding areas began during the Summer holidays. The dorms are friendly and welcoming; pupils are encouraged and helped to make the dorms as personal and homely as possible. The boarding at Perrott Hill is a strength of the school and this is recognised by the increasing number who choose to board.
