The determinants of energy efficient retrofit investments in the English residential sector

The results show that couples with independent child(ren) living in detached or semi-detached houses built before 1990 and with a length of residence higher than 1 year are more likely to invest in retrofits measures; compared to households living in the North East region, households living in London are less likely to invest. While there is empirical evidence supporting the landlord-tenant problem, households that have taken out a mortgage are more likely to invest in energy efficient retrofit measures than outright owners. To maximise their impact and effectiveness, future energy efficiency policies should target specific household groups with the lowest rate of retrofit uptake.
