Display Energy Certificate

A Display Energy Certificate (DEC) is a legal requirement for any public building over 250m2 . A qualified energy assessor must carry out the survey and produce the DEC.
If a building is over 1000m2 a DEC must be produced annually, and the accompanying advisory report is valid for 7 years. Where a building is between 250m2 and 1000m2 the DEC and advisory report are valid for 10 years.  Failure to display a DEC can lead to a penalty of £500, and £1000 for failing to possess or have a valid advisory report In addition to these penalties, it will still be necessary to commission the documents, otherwise further offences will be committed.

This service is provided by Energy Services at Nottingham City Council, who have insourced this service with a team of highly qualified energy assessors, with experience of delivering over 3,000 energy compliance services throughout the United Kingdom.
