Ecclesiastical Insurance has released information regarding idle buildings during COVID 19.
Two documenst have been added to my post of April 1st re vacant buildings on the Diocesan COVID 19 page. Please visit it HERE. (You will need to scroll down a bit.) They address things like mandatory check times -- every 24 hours if the building has a hot water heating system, radiator or baseboard and the heating is left on, and every 72 hours if the building is heated by oil / other and the water supply has been shut off, but the system not drained.
The two documents are also attached below for your convenience.
