Lateral flow testing kits have run out on the government's website after Prime Minister Boris Johnson announced an end to universal testing.
People who try to order tests on the official website, gov.uk, are currently receiving a message that says they are unavailable.
The message states: "Sorry, there are no home delivery slots left for these tests right now. The 119 service does not have access to more home delivery slots right now. You cannot order tests from NHS 111 or 999."
