Unfortunately you are not meeting your target to reduce your electricity usage

Review progress

Gas use in the Summer half term 2026 holidays has increased by 470% compared to Summer half term 2025. 

Between Saturday 23 May 2026 and Sunday 31 May 2026 you used 2,700 kWh of gas at a cost of £170. Adjusting for changes in outside temperature, this is still an increase of 2,300 kWh and 410 kg CO2. Ask the school site manager to check the heating controls to reduce gas use during the school holidays.

There is a large variation in your school's seasonal overnight electricity usage from 70 kW in the winter to 45 kW in the summer. This suggests heating is left running overnight during the winter. This can either be electric heating, or other types of heating that requires electricity for pumps or fans. Change heating settings to save £16,000 annually.
