Sir, – I received a Ber C2 certificate recently on foot of having solar panels installed. How did my improvements result in a disappointing increase in rating from C3 to C2? This distorted value has resulted in my C2 rating. My Ber inspector agreed that although the house is rated C2, the household would be rated as A3. We’re not particularly energy conscious or thrifty, but we have made improvements to our home and we don’t see this in our Ber rating.
