Can Optimal calculate my Display Energy Certificate (DEC)?
A. Yes. As Optimal automatically collects energy consumption data in real time, it will be able to calculate your DEC rating at any time, not just on the annual basis on which you are required to register your DEC. This provides customers with the added benefit of being able to monitor how they are progressing in terms of improving their DEC registration throughout the year, rather just taking a snapshot at the time the DEC is required.
