It’s logical to think that a newly built house which fully complies with Part L would be expected to reach the highest band of an EPC report, but it’s incorrect. Most new houses are expected to score between B and D on the Energy Performance Certificate. We might be building homes and units which are more efficient and cheaper to run than ever before, but we’ve got a long way to go in the next few years.
The EPC has been designed to be one point of reference whether you’re looking at a zero carbon home or a 500 year old castle. New homes which are built to the 2010 regulations are still expected to produce 15-20 kilograms of carbon dioxide per square metre every year.
The coveted ‘A’ band is reserved for buildings which create far less than that. In order to reach the ‘A’ band, you’d need to look at ways of dramatically cutting the annual fuel bills of your home – maybe through electrical generation or by using a cheap, sustainable fuel to heat your home such as wood.
As we move into the 2013 and 2016 changes to Part L, ‘A’ and ‘A+’ banded houses will become more common, but for the time being, there’s no shame in not being top of the class!
