Silverstone boss Stuart Pringle has given assurances that should the track's MotoGP event be cancelled due to coronavirus, all tickets will be refunded.
The circuit, which is also scheduled to run F1 and a British Superbike round in 2020, isn't due to run MotoGP until the end of August so should be safe.
"Many of you have booked tickets for our events later this summer including MotoGP and I fully appreciate you want to understand if these events will take place," said Pringle.
"The truth is, like so many other international sporting events scheduled to take place around the world, we cannot predict what the situation will be by the time we get to the summer months.
"However, I can wholeheartedly promise you that everyone at Silverstone, Formula 1 and MotoGP are doing all they possibly can to ensure we can run these events on their planned dates in July (F1) and August (MotoGP).
"In fact, as Formula 1’s CEO Chase Carey has stated, Formula 1 and the FIA do not expect to begin the Championship in Europe until after May although this is regularly being reviewed.
"I would like to reassure our fans that, should we be forced to cancel either Grand Prix, all customers who have purchased a ticket will be given the option of a full refund.
"We will, of course, continue to keep you updated as the situation in the UK evolves and I would like to take this opportunity to thank you for your support and patience in what is an extremely difficult time for everyone.
"Most importantly, I do hope you and your family members are safe at this worrying time."
