What information should be collected to produce a DEC?
If you are affected by this legislation and are required to display a DEC by 30th December 2008, you should start collecting energy consumption data now. You will need to obtain actual meter readings or consignment notes for all fuels used in your buildings that are affected by this legislation. This may include gas fuels, oil fuels, solid fuels, district heating and cooling, grid electricity and electricity generated on site or obtained by private distribution systems from other sites.
