Everyone in the UK over the age of five with coronavirus symptoms is to be eligible for a test, Matt Hancock has said.
England's Health Secretary announced the step in the House of Commons on Monday.
He said it had been agreed with his counterparts in Wales, Scotland and Northern Ireland.
Testing in Wales is currently limited to key workers, hospital patients and care home residents.
Mr Hancock told MPs in the Commons: "We are expanding eligibility for testing further than ever before."
He added: "Yesterday we conducted 100,678 tests. Every day we are creating more capacity and that means more people can be tested, and the virus has fewer places to hide.
"Today, I can announce to the House that everyone aged five and over with symptoms is now eligible for a test.
"That applies right across the UK in all four nations from now.
"Anyone with a new continuous cough, a high temperature or the loss or change of sense of taste or smell can book a test by visiting nhs.uk/coronavirus."
