BER what is it?

A BER is similar to the energy label for a household electrical appliance like your fridge. The label has a scale of A-G. A-rated homes are the most energy efficient and G the least efficient.

A BER certificate will be compulsory for almost all new homes by mid 2008. If you are buying or renting a new house or apartment now, you may already be entitled to a BER - so do ask the seller/landlord or their agent for it.

From the 1st of January 2009 a BER certificate will be compulsory for all homes being sold or rented.

BERs will be carried out by specially trained BER assessors, registered by Sustainable Energy Ireland (SEI). A list of BER Assessors is available within our Professionals section.

Who needs a BER?

A seller must provide a BER to prospective buyers or tenants when a home is constructed, sold or rented under the following circumstances:

  • New homes where planning permission was applied for on or after the 01st of January 2007
  • All homes for sale or rent on or after the 01st of January 2009

How Long will a BER Remain Valid?

A BER for a building will be valid for 10 years from the date of its being issued, unless there is a material change in the building in the meantime which could affect its energy performance – for example an extension to the building, a significant change to the building fabric or a change in the heating system or fuel used.

Therefore if a property which has received a BER is placed on the market within 10 years of that BER being issued, and the property has experienced no relevant alteration in the meantime, then that same BER may be used by the building owner for the purposes of meeting their obligations under the Regulations.

What are the BER Implementation Dates in Ireland?

The requirement to provide a BER is being introduced on a phased basis as follows:

New dwellings: The regulations apply to new dwellings for which planning permission was applied for on or after 1st January 2007. Transitional BER exemptions will apply to new dwellings for which planning permission is applied on or before 31st December 2006, where the new dwellings involved are substantially completed on or before 30th June 2008. New Non-Domestic Buildings: The regulations apply to new non-domestic buildings for which planning permission was applied for on or after 1st July 2008. Transitional BER exemptions will apply to new non-domestic buildings for which planning permission is applied on or before 30th June 2008 provided the new non-domestic buildings involved are substantially completed by 30th June 2010. Existing Buildings: (dwellings and other buildings) when offered for sale or letting on or after 1st January 2009. Large Public Service Buildings: A public body shall, in relation to a large building occupied by it on or after 1 January 2009, secure and display a BER certificate in a prominent place clearly visible to the public.

How is BER calculated?

A BER for a house is calculated using the Dwelling Energy Assessment Procedure (DEAP) software published by Sustainable Energy Ireland (SEI). The DEAP software will also calculate the carbon dioxide emissions associated with the house. The BER calculation includes energy use for building fabric, space heating, water heating, ventilation and lighting and is calculated on the basis of standard occupancy.

Who assesses BER?

A BER is carried out by specially trained BER assessors, registered by Sustainable Energy Ireland (SEI).
