The Energy Act 2011 states that from April 2018 it will be unlawful to rent out residential or commercial/business premises which do not meet minimum energy efficiency standards, with the lowest acceptable standard being an EPC Asset Rating of ‘E’. 

An EPC contains:

  • Information about a property’s energy use and typical energy costs
  • Recommendations about how to reduce energy use and save money

NDC undertake energy assessments and produce Display Energy Certificates (DECs) in line with The Energy Performance of Buildings Directive (EPBD). 

DECs are designed to show the energy performance of public buildings. They use a scale that runs from ‘A’ to ‘G’ - ‘A’ being the most efficient and ‘G’ being the least.

DECs are issued by accredited organisations such as NDC along with accompanying advisory reports that describe measures that can be undertaken to improve the energy efficiency of the building.  

ESOS is a mandatory energy assessment scheme for organisations in the UK that employ >250 staff. The Environment Agency is the UK scheme administrator.

Organisations that qualify for ESOS must carry out ESOS assessments every 4 years. These assessments are audits of the energy used by their buildings, industrial processes and transport to identify cost-effective energy saving measures.
