In early 2019 the UK ELLs came to an end with a follow-up survey sent to our participants in February. The UK team concentrated their efforts on analysis of the rich data collected; the National Report for the UK presents some interesting findings. For example, participation in the study led to significant changes in heating awareness and practices of the UK participants. Most of them were able to reduce the indoor temperature and still feel comfortable and warm enough. As a result of the laundry challenge the number of weekly wash cycles went down. Participants started to assess what needed washing more carefully. Some participants pointed to the time-saving benefits of the laundry challenge. The use of washing machines changed in some households (e.g. more use of shorter or energy-efficient programmes, lower temperatures, doing full loads). Many participants are committed to continuing with the new practices as the benefits were obvious to them. Overall, the project was regarded by participants as useful, interesting and enjoyable.
