There are reports of people knocking on doors saying they are doing coronavirus tests on behalf of NHS/your surgery etc.
Please note, there are no such initiatives. If anyone knocks on your door offering this, ignore them and call the police. These are thieves trying to take advantage of vulnerable people.
