I was considering installing solar panels and was told that in order to get the grant my house would have to reach BER C minimum.or at least BER D before installation.I contacted a local assessor and he quoted me €600 to carry out a BER.This man had visited my home which is a large 4 bed dormer bungalow previously. I thought the price was exorbitant as I assume the process only takes an hour to carry out.What would be the average price of a BER? It seems if I was to be sure my house was BER D I would have to have assessment carried out beforehand to make sure I would qualify for grant and again after installation of panels to get grant? Any way around this?
