This covers all corporate sites and schools who have opted in, validating bills and ensuring service areas are recharged correctly. The team run the Corporate Assets Decarbonisation Scheme, delivering phases of energy efficiency and renewables works with the aim of reaching net zero by 2030. The team also work closely with the wider Property service area, supporting energy efficiency work in the council's housing stock.


Renewable energy generation

We are fortunate to live on the sunny south coast. Although subsidies for solar electricity panels have ended, some companies will pay for the electricity you export, and it can still be worth fitting them if you have a good south-facing roof and/or will be at home during the day to use the free electricity. There are still subsidies or grants available from the government for solar water heating and renewable heating systems such as heat pumps. Transition Southampton members include people who have installed these and are willing to share their experiences, good and bad. See this blog where one member shares his experience of having a heat pump installed:
