DEC (Display Energy Certificate)

A Display Energy Certificate shows the energy performance of a building based on actual energy consumption as recorded annually over periods up to the last three years (the Operational Rating). The DEC also shows an Asset Rating for the building if this is available (by way of an EPC). A DEC is valid for one year and must be updated annually.
An Advisory Report accompanies the DEC and contains recommendations for improving the energy performance of the building. If you are an occupier of a building requiring a DEC, you will need to display a DEC showing an Operational Rating in a prominent place clearly visible to the public and have in your possession or control a valid advisory report.
At the moment DECs are only mandatory for public sector buildings. However, any organisation may opt to have a voluntary DEC - they provide a great starting point for an energy efficiency campaign and are an excellent tool for client and stakeholder engagement.
More details about DECs, what they are and what they contain, can be found in this government GUIDE.

EPC (Energy Performance Certificate)

An EPC looks broadly similar to the energy labels now provided with vehicles and many household appliances. Its purpose is to indicate how energy efficient a building is. The certificate will provide an energy rating of the building from A to G, where A is very efficient and G is the least efficient. The better the rating, the more energy-efficient the building is, and the lower the fuel bills are likely to be. Each energy rating is based on the characteristics of the building itself and its services (such as heating and lighting). Hence this type of rating is known as an asset rating.
In addition to requiring an EPC before marketing a property for sale or to let, an EPC may be required to support an application for RHI (Renewable Heat Incentive), FIT (Feed-In Tariff) and other schemes.
A domestic EPC differs from an EPC for a non-domestic building (e.g. an office) in the way it is carried out and the way the information is presented. Different qualifications are required for the assessors carrrying out domestic EPCs. only carry out non-domestic EPCs, but can refer you to partners if you require a domestic EPC.

TM44 Air Conditioning Inspections

All air conditioning systems with an effective rated output of more than 12kW must be regularly inspected by an energy assessor. The inspections must be no more than five years apart. This will include systems consisting of individual units which are less than 12kW but whose combined effective rated output is more than 12kW. The person who controls the operation of the system, such as the building owner or manager, has statutory obligations and duties of care in the operation and maintenance of air conditioning systems.
The inspection is designed to improve efficiency, reduce energy consumption, operating costs and the carbon emissions of the system. The assessment will highlight improvements to the operation of existing systems or opportunities to replace older, less energy efficient systems or oversized systems with new energy efficient systems.
Operators of air conditioning systems also have mandatory obligations under the F-Gas Regulation (e.g. leak testing and use of certificated personnel). As part of the inspection we will check your specific obligations and inform you what, if anything, you have to do to comply with the Regulations.
