It comes as ministers are considering a 10pm curfew for pubs next week with Justice Secretary Robert Buckland warning that young people are 'forgetting the rules'.
From tomorrow, the controversial so-called 'rule of six' will come in, as the government tries to tackle rising coronavirus infection rates by restricting meetings both indoors and outdoors.
Ahead of the crackdown, Mr Buckland has warned the government could go even further next week and introduce curfews.
He told Sky's Sophy Ridge On Sunday: 'I think that as you've seen we've been very prepared to move quickly where necessary and where the evidence points us.
'I think there's an issue about social occasions and social events and particularly young people getting together and enjoying themselves sometimes a bit too much and forgetting the importance of the rules.

'I think it would be idle of me to speculate as to what measures we might have to bring in as we approach the winter.'
Prime Minister Boris Johnson is believed to be considering introducing a 10pm or 11pm curfew on restaurants, bars and pubs if local measures are unable to bring the spread of the virus under control.
The move stems from a concern that adherence to social distancing measures diminishes the more people consume alcohol.
It comes amid rising fears that the virus could rampage through Britain once again.
Yesterday, more than 3,000 coronavirus cases were recorded overall in the UK for the second day in a row - the first time since mid-May that recorded cases have been above that level on consecutive days.
The Government said that as of 9am on Saturday, there had been a further 3,497 lab-confirmed cases in the UK, slightly lower than the 3,539 cases recorded on Friday.
Speaking about the rise in cases, Peter Openshaw, professor of experimental medicine, Imperial College London, said a 'trickle' of cases can turn into a 'cascade', adding that if people do not abide by the 'rule of six' now then the country faces going back into 'hard lockdown'.

Justice Secretary Robert Buckland warned that young people are 'forgetting the rules' ahead of the new limits on gatherings coming into force tomorrow
He said: 'I think everyone is in agreement that we really need to act very quickly now in order to prevent this from growing exponentially.
'I think that's the main point is that we must act fast because it's so much harder to get this sort of thing under control if you delay.
'Even a few days is potentially going to be quite dangerous now at this particular moment.'
Former chief scientific adviser and member of the Scientific Advisory Group for Emergencies (Sage) Sir Mark Walport has warned that the country is 'on the edge of losing control' of Covid-19.
Asked if he thinks Sir Mark is right, Prof Openshaw told Ridge: 'Well yes I think that is right.'
Police across Britain last night launched a crack down on illegal parties as revellers hit the town for boozy celebrations before the government's tough new 'rule of six' comes into force.
Officers broke up house parties in Altrincham, Stockport and Flixton, all in Greater Manchester, on Saturday night, while police in Nottingham tackled a 50 person gathering in Lenton.
In the largest gathering said to have been broken up by officers last night, a team from Greater Manchester Police dispersed around 70 party-goers from a house in Mottram.
Police are also investigating an illegal rave which took place in the leafy Surrey village of Wisley.
The crackdown came as revellers up and down the country hit the streets for a last hurrah before the government's new rule limiting the number of people in gatherings to six comes into play on Monday.
With little sign of social distancing, large groups of drinkers gathered at bars and restaurants in London, Nottingham, Manchester, Portsmouth and Leeds last night and into the early hours of this morning to take advantage of their last few hours of freedom before the government tightens lockdown restrictions again.
In London's West End, hundreds of drinkers could be seen singing along and dancing as a busker played a tune, with very few revellers paying attention to the government's social distancing measures.
Under Boris Johnson's strict new measures, groups of more than six can be broken up by police who will be able to hand out £100 fines to those who flout the rules.
This will double on each repeat offence up to £3,200 and only schools, workplaces and a limited number of other locations will be exempt.
The move, introduced to tackle the rising spread of coronavirus, comes as a Government-led study yesterday suggested the reproduction 'R' rate could be as high as 1.7 in England.
Tim Robson, the North East's representative on the national Pubwatch scheme, expected police officers would strictly monitor bars over the weekend to ensure they are operating safely.

He said: 'There is an anticipation that everyone is going to have a big last binge, but people are starting to get fearful and a lot of licensed premises have already been clamped down on by the police.'
Mr Robson, a former police officer, said it will be up to licensees to manage their premises and break up large groups from gathering together unsafely.
He added: 'There may be a rise in groups going out this weekend, but it will be probably to premises who don't have door supervision and control.'
Meanwhile Newcastle upon Tyne's director of public health Eugene Milne has said he did not think large numbers of people would go out for a big binge ahead of the tighter controls coming in.
He told Tyne Tees TV News: 'At the opening of lockdown there was a real fear that that might happen in the city, and that didn't happen so I think we can trust people.
'The idea of the rule of six is to make it easier for people to know how to stick with the guidance and I think one of the big problems has been the guidance has progressively got so complicated, so specific to particular areas, that it becomes very confusing for everybody.'
