It comes amid growing concern that Brits aren't following social distancing guidelines to halt the spread of the disease.
Over the weekend crowds of people flocked to the country's parks, beaches and holiday spots during the sunny spell the Mother's Day weekend - prompting the stark warning that further measures are set to be introduced.
The Prime Minister told Brits there was no ban on going outside - yet.
But Boris Johnson warned if people could not show they were staying 2 metres away from one another when they were outdoors more drastic measures could follow within hours.
The UK's pubs, clubs, restaurants and other social gathering venues have already been shut as authorities work to contain the outbreak.
Major chains including McDonald's, Next, Primark and John Lewis are already shutting their doors.
Meanwhile Britain's supermarkets are rationing items and urging people to trust Britain's food supply chains as panic-buyers ignore advice and continue to strip shelves bare.
As the country is told to stay home wherever possible, the PM told the nation in his daily press conference yesterday that the experts recommended fresh air for mental health and fitness purposes.
However that liberty could be restricted soon - if Brits don't change their behaviour.
Transport Secretary Grant Shapps warned the public that there is still time to avoid more stringent measures by obeying social distancing advice.
He said stricter measures including curfews are "all under active consideration", telling BBC News: "If we have to go there then we will go there."
The Cabinet minister insisted most people in the UK are intending to do the right thing by social distancing advice, but suggested they are unwittingly turning up to outdoors sites which are unexpectedly crowded.
"Please, restrict the amount you are going out, otherwise, as we said, we will have to move to the next level on these things and we're keeping that constantly under review," he added.
Asked about how imminent the measures are, he said: "I can't preempt something which is being worked on, thought about, as we speak, but I can tell you there's still the opportunity for people to make sure we do socially distance ourselves from each other."
It comes as the Department of Transport offers train ticket refunds to keep Brits off the country's railways, as operators heavily reduce their timetables.
In the capital, Mayor Sadiq Khan has warned Londoners to stay off public transport unless travel is essential, saying the city's Tubes, trains and buses must be available for key workers.
However despite the country's workforces being urged to work from home if they could, photos of packed train carriages and station platforms during this morning's rush hour in London sparked fury.
The packed transport and weekend scenes of Brits flouting social distancing rules has prompted calls for the country's leaders to bring in a full lockdown.
