Reminders

There is currently a lag with your gas data, this has been raised with your supplier. Your school has eight gas meters. Four of the meters are not capable of sharing data and need to be upgraded. Therefore, please keep in mind that we're not displaying gas consumption data for the Sixth Form, Bancroft Teaching block, Drama or Chapman Sports Centre on your account. In addition, we have not been receiving data from the minor electricity meter in the Sixth Form block since you changed supplier on 1st Oct 2025. We are working with your supplier to rectify this.
