Q&A: Energy efficiency in old houses

Improving the energy efficiency of the UK’s housing stock has become increasingly important in light of increasing energy prices. This is particularly the case in older properties that tend to be less energy efficient. 

Research by the Office of National Statistics, based on Energy Performance Certificates (EPCs), shows energy costs and carbon emissions in existing dwellings are double those of new dwellings.  According to research from BRE Trust (PDF), the UK’s housing stock is the oldest in the world and being replaced at a slow rate. Wales has the oldest stock in the UK with over a quarter of houses being 100 years old or more.
