Useful COVID website for UK types

The NEU has set up a website allowing you to check the Covid status around individual schools (you can also enter a postcode and then pick one of the schools on the map that appears), and it definitely goes to a lower level than the government website - for instance if I check the nearest school to me then it says that Medway has a rate of 11/100,000, as the government website says, but it also says that Chatham South West and surrounding areas* (my part of Medway) has a rate of 22/100,000. It also has a useful link to click through to the government page on local lockdown restrictions - though confusingly that's referred to as the 'watchlist status'.

* it's apparently averaging the rate in the MSOA the school is in, and all surrounding MSOAs (MSOA = Middle Layer Super Output Areas = about 2000 households/7200 people)
