If you are looking to sell, buy or rent a property from Thursday 9th January 2013 there should be a current BER available and it must be stated in any advertisements, where such advertisements are taken relating to the sale or letting of that building.
There are a few exemptions from having a BER for a building, such as listed buildings are exempt, but remember if you are a buyer or renter of a listed building you can still ask for a BER rating as it will be beneficial in estimating your future energy bills.
S.I. 243 of 2012 European Union (Energy Performance of Buildings) Regulations, 2012 makes provisions for the inclusion of BER information in property sale and rental advertisements.
A brief review of some of the online property pages in Ireland today shows there is already widespread non-compliance with the regulations, which can result in a fine of up to €5,000 or, in extreme cases, up to three months in prison.
