Research carried out by Sustainable Homes and 25 housing
providers examined data on over 500,000 homes. It looked at the
impact of energy efficient homes on the bottom lines of social
The Sustainable Homes study, "Touching the voids", found
- There is a correlation between the energy efficiency of homes
and the number of void days. As homes become more energy efficient
they are void for a shorter length of time - on average, 31%
shorter for band B properties compared to those in bands E and
- Landlords with more energy efficient stock spend less on
refurbishing void homes, less on repairs and less on staff time to
- The highest performing band A properties spent 30% less time in
arrears compared with the worst performing homes. Colder homes,
especially those in band F, have on average two weeks more rent
arrears than more energy efficient bands each year.
- Other cost savings identified include time spent seeking
overdue rent payment, legal costs and court costs which decline by
around 35% for more energy efficient homes.
The boost to landlords' bottom lines from more energy efficient
homes could be significant - with potential for a 10,000 home
provider to save over £2.4 million if they upgraded their stock
from an average SAP 65 to SAP 75.
