It means 8 April was the day on which the highest daily total of covid-associated deaths in England occurred. See:

It suggests that infections peaked
before 'lockdown'. I've read studies suggesting anything between 19 and 28 days between infection and death. House arrest began on 23 March, giving 16 days between 'lockdown' and peak deaths (although that warehouse of epidemiological exactitude, Matt Hancock, tried for a while to claim 'lockdown' began on 16 March, possibly because of innumeracy, but more likely because he's a mendacious incompetent).
Note: when I write 'lockdown' I am, of course, referring to 'lockdown' mk1, not 'lockdown' mk2, the one de Pfeffel claimed not long ago we wouldn't be having.
