My guess would be that it is catching up, but still much lower.
However, productivity per hour (in US dollars) is still much higher in the UK than e.g. Australia, the EU-28, the OECD or Canada. I'm not sure why this study took 2010 as a baseline though, it seems to be a bias towards how well countries copied with the financial crisis.
I don't know, the OECD doesn't have data apparently: https://data.oecd.org/lprdty/gdp-per-hour-worked.htm
