In Northern Ireland, 123,000 people were likely to have had COVID-19 last week, or one in 15 people: up from 108,700, or one in 17 people.
Both nations are slightly below their recent record infection levels.
Senior statistician for the ONS COVID-19 infection survey, Kara Steel said the “rapid rise” is being fuelled by the growth of the Omicron BA.2 variant across the UK.
“Infection levels remain high, with the highest levels recorded in our survey seen in England and Wales and notable increases among older age groups,” she added.
The latest figures come as the free COVID testing comes to an end for the majority of people in England.
