“…This suggests that the at this time, the LA level is of limited value for understanding differences in energy performance, perhaps because local authorities, through local councils, have not yet played the role envisaged for them in the future by central government in delivering net-zero commitments (Rankl et al, 2023). Our observation of only minor differences at LA level is consistent with previous work examining (a lack of) differences in retrofit needs in the UK at this level (Ahlrichs et al, 2022). The high variance at the property level is a reminder of the heterogeneity in housing, even within small neighbourhoods such as output areas.…”

Achieving net zero in the UK requires radical improvements in energy efficiency in housing combined with the decarbonisation of domestic heating. Achieving the energy efficiency goals requires a systems approach which takes account of variations at the level of individual properties but also the levels of neighbourhood and the local governance context. Our study provides insights into the scale of the challenge and how this varies by spatial context using property-level energy efficiency measures from Energy Performance Certificates data between 2008–22 and covering approximately half of the residential stock in England and Wales. We use a series of multi-level models to provide insights into how differences in energy efficiency are related to factors at each scale. Our findings show that, while the great majority of variation lies at the property level, there is some variation at the neighbourhood (output area—OA) level. Controlling for property characteristics, energy efficiency is slightly higher in neighbourhoods characterised by more disadvantaged populations. There is little evidence, therefore, that more affluent groups are either choosing to move into more energy-efficient housing or making a significant effort to invest in energy efficiency. While government support has been targeted at more disadvantaged groups, this suggests that more will need to be done to motivate or require more widespread action if the UK is to meet its net zero targets. There is only small variation at the local authority (LA) level suggesting little difference in the range or effectiveness of strategies by that tier of governance, but also that all households face similar challenges going forwards.

Understanding transaction costs of energy efficiency renovations in the Swedish residential sector

The residential sector has a large potential to reduce its energy use. Improving the energy performance of buildings is one way to realise this potential. For single-family buildings, improving the energy efficiency by energy renovations can produce a net financial gain. However, there are unaccounted barriers that act as impediments for house-owners to undertake energy efficiency measures. This study postulates that transaction costs are such a barrier. Transaction costs are defined as the cost of making an economic exchange on a market in addition to the market price. The purpose is to empirically estimate the magnitude of the transactions costs and its determinants for energy efficiency measures in the residential sector. Specifically, the transaction costs for heat insulation and energy-saving windows in Swedish single-family buildings are assessed. The analysis is based on a unique dataset, constructed from a web-based survey. The results indicate that transaction costs for energy efficiency measures are considerable. The average transaction cost to make additional heat insulation is SEK 18,046 (EUR 1,510) and SEK 21,106 (EUR 1,766) to install energy-saving windows. The determinants of the transaction costs are cognitive limitations, social connectedness, asset specificity and previous experiences. Therefore, to reduce the transaction costs, the complexity of energy efficiency measures must be addressed, potential opportunistic behaviour must be reduced, and financial options expanded.
