This very useful Google mobility data, allows us to see how both the country and each local authority is performing.
The reports show how visits and length of stay at different places change compared to a baseline, using the same kind of aggregated and anonymised data used to show popular times for places in Google Maps.
You can view the latest reports here: https://www.gstatic.com/covid19/mobility/2020-04-05_GB_Mobility_Report_en.pdf
