The primary source of heating for government offices in Whitehall is the Whitehall District Heating System, which is operated by the Government Property Agency (GPA). GPA has ongoing plans to reduce carbon emissions from and decarbonise the district heating system.

  • In 2021/22FY, a pipework lagging project was completed to reduce heat losses and provide carbon savings.

  • In 2022/23FY, it is planned to start a project to lower the operating temperature of the system from 145oC to 95oC.

  • Forecast reductions in Carbon from the completion of both projects is approximately 17%.

  • GPA has plans from 2025 to consider a decarbonisation of the Whitehall Boiler System that feeds the district heating system.

Other government office projects are ongoing in and around Whitehall to reduce energy consumption and carbon emissions through upgrades to LED lighting and HVAC (heating, ventilation and air conditioning) systems.
