This type of certificate is issued for public buildings only. The certificate must be displayed in a public place.
DEC Validity is 12 months from the date of issue. There are penalties, and
fines imposed for failure to display a valid certificate.
The Advisory Report will contain recommendations for
improving the energy performance of the building. A DEC is
valid for 12 months and needs to be updated annually. The
Advisory Report is valid for 7 years. There are penalties, and
fines imposed for failure to produce a valid advisory report.
Display Energy Certificate (Example Below)
The certificate will also display an:
Asset Rating - means a numerical indicator of the amount of energy estimated to meet the different needs associated with a standardised use of a building, calculated according to the methodology approved by the Secretary of State.
The asset rating will affect your business, this is the key
indicator of how energy efficient your business premises is to
Operational Rating - means a numeric indicator of the amount of energy consumed during the
occupation of the building over a period of 12 months unless:
Where on 4th January 2009: the occupier of a building has been in occupation for less than 15 months
or, entered into occupation of the building before 6th April 2008; or
entered into occupation on or after that date but did not have an energy performance certificate made available or given to it.
In these cases the operational rating specified may be calculated over the period in which the occupier has been in occupation.
& SBEM Assessors
Assessment of Non-Dwellings, offices, manufacturing
premises, and industrial buildings will require a Commercial EPC,
the survey, inspection of premises, and certificate issued
using SBEM calculation tools by a qualified (NDEA)
Non-Domestic Energy Assessor.
Procedure (SAP) for New Build
Dwellings - property developments and existing property, where for example
an extension has been added to an existing home. Larger complex commercial/industrial buildings will be assessed using
computer software using SBEM methodology (Simplified Building
Energy Model) or DSM (Dynamic Simulated Model) methods.. All inspections will be carried out by an
energy assessor, a competent person as defined under the National
Occupational Standards. Where required, existing properties
require Energy Ratings, this will also include public
buildings. Refer to EPC
Green Deal -
the scheme is improve insulation and provide financial backing
for renewable energy equipment for house holds and businesses.

Homes & Dwellings:
Energy Assessors for newly constructed dwellings
For newly constructed dwellings, (i.e. New Build Homes) the approved software will make use of the SAP approach.
These are also known as On Construction
Energy Assessors. See also SAP Assessors.
Part L compliance requires that New Homes are subjected to an Air
Tightness Test (Air
Leakage Test, or Air
Pressure Testing) and an Air
Permeability Test certificate obtained.
Energy Assessors for Public Buildings

the following methods - SBEM & DSM (Dynamic
Energy Assessors for

An EPC is required on construction for all
new build dwellings. See SAP
EPCs are also required for the construction, sale or rent of public buildings
other than dwellings with a floor area over 1,000 m2. SBEM methods
shall be adopted for the energy assessment of the building. Please refer to SBEM
From 1st October 2008
Display Energy Certificates (DEC) required for all public buildings
with floor area >1,000 m2
Rental Property, Private Landlords, & Buy-to-let Property
Lettings - All properties will require Energy
Performance Certificates (EPC)
issued by a Domestic
Energy Assessor on, or before this date. Further information for
this sector is available at:
First inspection of air-conditioning systems is required find out more
about assessment and your obligations regarding Air
Conditioning energy assessment.
Public buildings and institutions will be required to display a DEC.
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. DECs need to be updated each year.
Property and facilities managers affected by this
new legislation will need to have annual energy meter readings and are advised to start collecting meter readings now to ensure they have sufficient data ready for
Cost of an EPC for Commercial Premises
Commercial EPC costs associated with the issue of an Energy
Performance Certificate (EPC) for
non-dwellings or Display Energy
Certificates (DEC) for
public buildings are difficult to quantify due to the nature of the
construction, the complexity, and size of the building which is being
examined in each individual case. The EPC cost using SBEM calculations is
difficult to ascertain due to the inherent properties of buildings which
can vary greatly, almost certainly the EPC price for the commercial
property market will be significantly higher than the domestic
counterpart. Buildings which cannot be assessed using this calculation
method will likely use DSM (Dynamic Simulation Model) which may incur even
higher costs. SBEM calculation of energy ratings for buildings will cover
approx 70% of the commercial property market. The information required to
produce SBEM Calculations must be
submitted by the asset owner. The associated costs of air conditioning
energy assessment, if such a system is installed, must also be taken into
account. Surveyors for Commercial EPC's will offer quotes, prices and costs
based on the information that can be supplied by the building owner or
facilities management, to reduce the costs for the EPC it is essential to
provide the assessor as much information as possible, this will help you,
the asset owner, obtain competitive quotes for Commercial EPC's and reduce
prices. Commercial EPC quotations are largely based on how much
information you can provide about the property.
Many buildings will be affected by the introduction of Commercial
Energy Performance Certificates in the future, these include but are
not limited to:
Certificates for Retail Units, New Build Homes & Dwellings, Shops, Industrial Units, Hotels, Offices and small business premises.
Certificates for New Build & Existing commercial units - SBEM
Commercial Buildings Assessors
Performance Certificates EPC for Private rented
& landlords. A domestic
energy assessor may be used in most cases, however, if the
property is deemed as commercial, an authorised, qualified commercial
energy assessor will be required.
From 1 October 2008, if you are renting out your property, you will need to provide a certificate to any prospective tenant. Refer
to EPC Timetable
There is no need to obtain a Energy Performance Certificate for an existing tenancy. Once obtained, a certificate remains valid for up to10 years.
If a valid Energy Performance Certificate still exists when changing tenants no new certificate is required. This applies to both private and social sector landlords and tenants.
timetable and details for the implementation of EPC's for buildings
has changed. (Nov 2007)
Please refer to: Commercial EPC for
the revised schedule for implementation.
EPC Training Courses for Energy Assessors for a career in energy
inspection of commercial buildings.
The Government will be introducing new checklists for owners of
commercial premises regarding heating systems these checklists will
be made available to enable businesses and building owners/occupiers to get information about the energy efficiency of their heating and hot water systems. Refer
to Business Energy Saving
Measures to reduce overheads and improve your buildings energy
The checklist is designed to be completed by a heating engineer and given to a building owner/occupier during a service or maintenance visit. It gives a basic assessment
of the efficiency of the heating and hot water systems and an indication of whether the
customer would benefit from a more thorough assessment of their system.
deal scheme will be launched in the UK in 2012. Grants will be available
for improvements to heating, insulation and renewable energy equipment.
Find out more about the Green Deal.
Energy for business is not cheap, many companies are now revaluating
the costs for commercial energy, as tariffs continue to rise, gas and
electricity prices to the domestic consumer and commercial sector have
increased significantly. If your company or business is considering an
alternative supplier please refer to Switch
Energy Suppliers for help and advice when switching energy providers.
What buildings will be affected by the introduction of DEC's?
Only buildings occupied or part occupied either by a public authority or an institution providing a public service to a large number of persons and who are therefore frequently visited by those persons (referred to as relevant institutions), and with a total useful floor area greater than 1000m2 are affected by this legislation.
owned buildings do not require a DEC. Although the scheme may
be extended to include the commercial sector in the future.
