Residents can use the radiator valves (and a programmer or room thermostat where fitted) in their home to control the heating. For example people can turn down the temperature if it is too high or when nobody is at home. Although tenants and leaseholders are charged for their heating differently, all charges are ultimately affected by how much heat is used on the communally heated estates. Therefore, if more residents reduce energy use it will help to cut heating costs for everyone.
