It is the first time the government figures have included deaths in care homes and in the community as well as those in hospitals.
Coronavirus: UK now has second highest number of COVID-19 deaths in Europe
More than 26,000 people have died with coronavirus in the UK, making it the second worst-hit country in Europe, new figures have shown.
A total of 26,097 people have died after contracting COVID-19, according to government data which included deaths in care homes and the wider community for the first time.
The total is up from 21,678 coronavirus deaths in UK hospitals announced on Tuesday - but Foreign Secretary Dominic Raab insisted there had not been a "sudden surge".
The latest deaths included a 14-year-old in England who had no known underlying health condition.
Public Health England (PHE) said the new method of reporting deaths showed an additional 3,811 fatalities since the start of the coronavirus outbreak, about 70% of which were "outside hospital settings".
There were 765 deaths reported in the 24 hours to 5pm on Tuesday.
The total number of UK coronavirus deaths was recorded between 2 March and 28 April and was around 17% higher than previous data showed, according to PHE.
Its medical director Professor Yvonne Doyle said she could not yet say whether deaths in care homes were falling.
She told the daily Downing Street briefing: "We should know that soon because the hospital curve has declined."
Prof Doyle said the figure for deaths in care homes may be revised up further.
She added: "In due course those deaths sadly may occur on death certificates, so we may expect more than we are seeing at the moment."
The UK's new coronavirus death total means it is the third worst-hit country in the world, behind Italy with 26,872 deaths and the US with more than 59,000 fatalities, according to Johns Hopkins University, which is tracking the outbreak.
Nearly a third of all care homes in England have reported suspected or confirmed COVID-19 outbreaks.
Some 4,516 homes have reported outbreaks since 17 March up until Monday this week - around 29% of the total care homes.
In every region in England more than a fifth of care homes had reported outbreaks.
Health Secretary Matt Hancock said on Tuesday he wanted to "bring as much transparency as possible" to the coronavirus death figures by including those in care homes and the community.
Mr Raab - standing in for Boris Johnson following the birth of the prime minister's son - said there was a "joint horror" across the House of Commons at the number of people killed in the outbreak.
Chief scientific adviser Sir Patrick Vallance had suggested in March that keeping the UK's death total below 20,000 would be a good outcome.
At Prime Minister's Questions, Labour leader Sir Keir Starmer said: "We're clearly way above that number and we're only part way through this crisis and we're possibly on track to have one of the worst death rates in Europe."
He took issue with Mr Johnson's comments about the "apparent success" of the UK's strategy, adding: "Far from success these latest figures are truly dreadful."
Coronavirus: Businesses wonder if they can survive - and whether it's worth trying
Pubs and restaurants are facing a 50% drop in trade even after they reopen - especially if social distancing measures remain.
COVID-19 has brought parts of the economy to a standstill.
At a stroke, lockdown measures emptied the streets, closed shops, offices, pubs and restaurants, and consigned millions of people to the novelty of working from home, or the uncertainty of a furloughed salary.
Now, with the first indications that restrictions may be eased, businesses are wondering how they can reopen safely and, for all the government support on offer, whether they can survive - or if it is even worth trying.
Safely lifting the lockdown poses a profound challenge to business. At its heart is the new reality of social distancing - the requirement to keep a 2m (6.5ft) gap between staff, customers and colleagues to avoid the risk of coronavirus spreading.
It is the metric that may soon define the pace and success of Britain's economic recovery, and the culture and practice of workspaces for months and perhaps years to come.
Firms will have to cut attendance accordingly, retaining a work-from-home culture or thinning staff, and public transport will have to adjust accordingly. Sky News understands that FTSE 100 companies are already preparing for such measures to be in place until the summer of 2021.
The more immediate and damaging impact will be on customer-facing businesses such as shops, personal services and hospitality.
In pubs, restaurants and entertainment, it could mean a 50% drop in trade.
Bloomsbury Bowling in central London opened 15 years ago, in the same week the 7/7 bombers destroyed a bus in Tavistock Square just round the corner.
Owner Jon Dalton, who also runs a chain of pubs in the capital, has never suffered a blow to business like this.
"We went from 100mph to nothing. We had our best-ever year, and now we have no business," he told Sky News, speaking in a venue that typically hosted several hundred people a night.
He has furloughed more than 200 staff across his companies and is thinking about how he might return to some kind of safe trading.
For his pubs, he is working on an app that would allow people to order drinks remotely and have them delivered to avoid a packed bar.
In the bowling alley, he can close every other lane to ensure a safe distance, or split a single group of eight players across two lanes.
But both options would lead to a drastic reduction in the number of people he can accommodate and the revenue he will generate.
"You are looking at a 50% drop in revenues at best. Nobody knows how fast confidence will return, how soon people are going to want to go out," Mr Dalton said.
Like many in the hospitality industry, he wants government to extend the furlough scheme beyond the current end date of June and, when the time comes to open, to scrap VAT for the sector so businesses can survive and perhaps tempt customers.
Pied a Terre, a Michelin-starred restaurant in Fitzrovia, offers a more sedate atmosphere but faces the same challenge.
David Moore opened the doors 28 years ago, only previously closing when fire ravaged the building.
Social distancing may be impossible for five members of staff in the narrow corridor that links the two dining rooms - and he will have to remove several of the 14 tables, taking revenue with them.
Mr Moore has used the furlough scheme to retain staff, but believes the hospitality industry needs a government-backed deal with landlords to survive a lengthy shutdown. The proposal is for nine months' rent to be deferred and tacked on to the end of leases, with a hardship fund for landlords who are as desperate for the income as restaurateurs.
Even if all that happens, he is unclear whether the numbers will stack up.
"It really is a small restaurant, but it can have maybe 40 people on the ground floor. Okay, I have got the rates holiday, for which we are really grateful, but if we're only going to be doing 20 people and I'm paying the same rent, it's going to be tricky to see how the business will make money, how it will survive," he said.
"If you gave me a favoured date to come back, I'd say let's do the first week of September, because that's historically busy for the hospitality world. But if we go that far, there'll be so many businesses that won't be able to survive due to rental payments, and other costs that just keep ticking along regardless."
Customers have adapted to social distancing in supermarkets out of necessity. Now the 2m gap and one-way shopping mark the way forward for high streets that are currently deserted.
When non-essential shops reopen, they will have to change - and for now, we may have seen the end of browsing.
There are questions too about the trend towards offering customers retail "experiences" which may be impossible with social distancing
Cristina Bruzzolo, who runs the independent Colibri boutique in Islington, says she will try to adapt.
"We will allow people to come in at set times for browsing and we will have also a booking system online so that people can book to try clothes on," she said.
The government has refused to discuss how or when lockdown might be eased, and points to the substantial package of support it has offered to businesses.
The furlough scheme is already paying the partial wages of more than four million people, and grants, rates holidays and state-backed loan schemes are available.
