Hillhead event director Richard Bradbury explained: "Under these guidelines, it is clear that the show will not be able to operate legally in June this year.
"Our priority is to provide the Hillhead experience that our exhibitors and visitors have come to expect but, with the continuing uncertainty around travel restrictions and social distancing measures, this is not achievable in 2021.
"By delaying the show until June 2022, the full benefits of a completed vaccination programme will have filtered through, allowing us to deliver a safe and vibrant event."
The bi-annual Hillhead exhibition is staged at a former Tarmac quarry just outside Buxton in Derbyshire, central England. The next staging of the event, the UK's largest quarrying, construction, and recycling equipment showcase, will now be from 21–23 June 2022.
