Energy Performance Certificate - Newbuild Homes

Summary

The Government's Standard Assessment Procedure (SAP) for assessing the energy performance of dwellings. The indicators of the energy performance are energy consumption per unit floor area, an energy cost rating (the SAP rating), an Environmental Impact rating (based on CO2 emissions) and a Dwelling CO2 Emission Rate (DER). The SAP rating is based on the energy costs associated with space heating, water heating, ventilation and lighting, less cost savings from energy generation technologies. It is adjusted for floor area so that it is essentially independent of dwelling size for a given built form. The SAP rating is expressed on a scale of 1 to 100, the higher the number the lower the running costs. The Environmental Impact rating is based on the annual CO2 emissions associated with space heating, water heating, ventilation and lighting, less the emissions saved by energy generation technologies. It is adjusted for floor area so that it is essentially independent of dwelling size for a given built form. The Environmental Impact rating is expressed on a scale of 1 to 100, the higher the number the better the standard. The Dwelling CO2 Emission Rate is a similar indicator to the Environmental Impact rating, which is used for the purposes of compliance with building regulations. It is equal to the annual CO2 emissions per unit floor area for space heating, water heating, ventilation and lighting, less the emissions saved by energy generation technologies, expressed in kg/m2/year.

Do I require a commercial Energy Performance Certificate?

If you are selling a building before it has been built, you will need to provide the prospective owner a full EPC and recommendation report.

What is contained within a Commercial EPC?

The certificate will provide the energy rating of the building from A - G, where A is the most efficient. The energy rating is based on the characteristics of the building itself and its services (such as heating and lighting). The certificate is accompanied by a report which includes cost effective recommendations to improve the energy ratings. For each improvement indicative paybacks are listed.

How long is the EPC valid for?

An On Construction EPC is valid until the property is sold. If the new owner decides to sell a Residential EPC will need to be generated to complete this sale. The On Construction EPC can not be reused.

Who is responsible for commissioning an EPC?

Developers are responsible for ensuring that an Energy Performance Certificate is made available. Failure to provide an EPC means you may be liable for a fine ranging from £500 - £5000.

Which type of properties are affected?

All On Construction buildings

  • New Dwellings
  • New Commercial Buildings

EPC's are not required on construction, sale or rent for:

  • places of worship
  • temporary buildings with a planned use time of less than two years
  • stand alone buildings with a total useful floor area of less than 50m2
  • agricultural building with a low energy demand

How Much will an On Construction EPC Cost?

The cost will vary according to factors including size, availabilty of drawings, complexity and number of buildings.

Timescales for Implementation

All commercial buildings for sale or rent now require an EPC.
