Silverstone have sent out the following communication:
"2021 Dates
Looking positively ahead to 2021, we’re pleased to announce that our provisional dates for next year are 30 July – 1 August. As usual, these will remain provisional until the dates for the British Grand Prix are ratified by the FIA (usually at the start of December) but be sure to pop the dates in your diary and we hope that this helps with your planning for now.
We hope that you’ll be able to join us next year for our postponed 30th anniversary party as well as a series of other deferred celebrations… plus some brand new ones; it’ll be an incredible event. We’re also looking at the ways in which we can pay a fitting tribute to the inspiring key workers who have supported us all through this very difficult period, too. More on that soon.


Tickets for next year’s event will be available in the Autumn."

I'll post more info as I get it...
