Eton College is fully boarding.
Their staff are still working:
Accommodation for key workers.
"We have offered accommodation, free of charge, within some of our now empty boarding houses for adult key workers, where they need alternative accommodation because their own families are self-isolating." ...
"Eton College is opening its doors to hundreds of children of key workers and the most vulnerable pupils from Maidenhead, Slough and Windsor. "
"The £42,000-a-year school has decided to stay open throughout the crisis, including the Easter and summer holidays if necessary, to teach children aged 5-13 whose parents are nurses, cleaners, porters, police and work in other critical services." ...
"Eton is offering its EtonX online self-study courses to every secondary school in the country, free of charge. Courses include guidance on writing CVs and preparing for interviews, as well as improving creative writing and essay writing skills."
