Downing Street also said that the Winter Plan will set out how people will be able to see their loved ones at Christmas, adding that ministers will be warning that this will not be a normal festive period.
The "COVID winter plan" is expected to place more areas into the higher tiers.
Prior to the lockdown, pubs and restaurants had to have everyone out by 10pm; however, it is understood that last orders will be at 10pm and curfew will be pushed back to 11pm from 2 December, according to Sky News.
Mr Sunak said the localised tiered system is a "far better way" to tackle Covid-19 as he confirmed the Prime Minister's plans, which are expected to be approved by the Cabinet on Sunday.
The government's scientific advisory group, known as SAGE, is expected to publish reports on Monday showing that the original three-tiered strategy wasn't strong enough and recommending tougher restrictions when it returns.
Calum Semple, a professor of child health and outbreak medicine at Liverpool University, predicted that people would ignore the government's restrictions if they are not relaxed over Christmas.
Despite not agreeing a final set of regulations, the government says ministers have "endorsed a shared objective of facilitating some limited additional household bubbling for a small number of days".
"But the prime minister and his scientific advisers are clear the virus is still present - and without regional restrictions it could quickly run out of control again before vaccines and mass testing have had an effect".
"That would put in jeopardy the progress the country has made, and once again risk intolerable pressure on the NHS", the spokesperson explained.

During a vote on the current four-week system earlier this month, 32 Conservatives rebelled to oppose the measures and 17 more, including former prime minister Theresa May, abstained.
Steve Baker, one of 70 lawmakers who have written to Johnson with their concerns, said they can't support the approach unless the government can show the restrictions planned for after December 2 will have an effect on decreasing COVID-19 transmission, "and will save more lives than they cost".
Johnson's office confirmed plans to begin a nationwide vaccination program next month, assuming regulators approve a COVID-19 vaccine.
Downing Street will hope this - combined with an easing of restrictions over Christmas, will lessen the scale of the rebellion.
Labour has so far been supportive of the need for restrictions to slow the spread of Covid-19 and a full-scale Commons defeat on the plan is unlikely.
"Obviously that's something that we would like to do and it's been a hard year for all of us, but as I said it's not going to be a normal Christmas this year".
She called for clarity about what economic support package would accompany different types of restrictions.
Ahead of the almost month-long stay-at-home lockdown, England had been placed in a three-tier system of graded social distancing rules based on the infection rates in particular regions.
Johnson's government has responsibility for health policy in England but devolved governments in Scotland, Wales and Northern Ireland coordinate their own responses to the pandemic.
Britain has suffered more than any other country in Europe from the coronavirus, recording more than 54,000 deaths from 1.4 million cases.
