According to a study conducted by the University of Cambridge, adding insulation to UK homes only provides short-term energy savings that appear to be cancelled out within a few years by an increase in energy use.
Once the gas-use patterns of more than 55,000 homes across England and Wales were analysed, researchers found that any fall in gas consumption achieved by retrofitting wall insulation was voided within four years.
“We found that energy efficiency retrofits are often combined with home improvements that actually increase consumption, such as extensions,” explained Cristina Peñasco, an associate professor in public policy at the University of Cambridge, who co-authored the study.
