The Elm Sports Centre is a brand new, state-of-the-art indoor sports facility located on the outskirts of the town of Hertford. The sports hall can cater for a wide variety of sports and activities including netball, basketball, badminton, 5-a-side football, futsal, cricket nets and table tennis as well as martial arts and exercise classes. 

During school hours, the Elm Sports Centre is utilised by the students at Simon Balle All-through School but is otherwise available for hire to community groups, sports clubs and members of the public.

The Elm at Simon Balle is set in a quiet location close to Hertford town centre and with easy access to the A414 and A10. Hertford East rail station and Hertford Bus Station are both within walking distance. The site also benefits from free parking for 150 cars.
