..detached house with 2 bedroom . Heated by either oil or stove. There was a small extension at the rear of the property. The walls were previously pumped with beaded insulation and attic insulation. The reason for getting the BER rating is to avail of a grant for a recently installed 4KW solar PV. The installer noted I need to get a BER for the grant and the easiest approach is for the person doing the rating to contact him directly.
