Limerick Energy Rating are delighted to offer you a Limerick BER cert service. Following a site visit by our SEAI registred BER Assessor Limerick we can issue you a Building Energy Rating certificate (BER CERT) indicating your home's energy performance. It is similar to the energy label for household appliances. The certificate rates the estimated energy use of your home on a scale of A-G. A-rated dwellings are the most energy efficient and will tend to have the lower energy bills. G-rated are the least efficient.
