The data appears to be licenced as OGL 3.0. I was wondering if this data had been included in OSM yet? Or if it could be used as a checklist to see if we’ve mapped the sites? Presumably such places could be tagged as leisure=bathing_place?
I had a similar thought when I saw the data set for Scotland a while ago. I also think that leisure=bathing_place could be a good fit for many of the “bathing waters” in the UK. The data should also contain the EU bathing water ID which can be recorded in the OSM tag ref:EU:bwid.
