The institution of energy consulting services is one of the several government instruments for improving the efficiency of energy usage in many European countries. Various forms of advice on energy issues are offered to households. In Sweden, there has been a drop in the number of households who avail of this service, even though it is offered independently, free of charge and easily accessible. Instead, Swedes have been increasingly seeking information on the Internet (websites, blogs and social media), which can be seen as both a challenge and an opportunity for the energy consulting service offered by Swedish municipalities. The aim of the literature study is to present an overview of current research in the area of energy consulting targeting households. This to identify central themes in the research front, identify knowledge gaps and discuss which challenges previous research emphasise for energy consulting services targeting households. The results show that research indicates that a measurement-feedback-communication strategy for households is necessary if one wishes to effect a change in consumer behaviour. Today, consumers expect more individualised information than before. Here, the three dimensions of sustainable development can be useful. Energy consulting is also better appreciated if it occurs in situ-at the customer's home. How it can and should be developed in an increasingly digitalised world is a topic we think is vital for future research. Also, with sustainable development becoming increasingly important in this century, an interdisciplinary approach to energy consulting is strongly recommended by the authors of this paper.
