The prime minister last chaired a COBRA meeting on Thursday to discuss the UK's response to Iranian strikes on energy infrastructure in the Gulf.
He also chaired a meeting in late February to discuss the initial US-Israeli strikes on Iran.
It comes as the war threatens to push up energy costs and inflation.
Leading forecaster Cornwall Insight has predicted Ofgem's July energy price cap will rise from £1,807 to £1,973 a year for an average household.
That's a rise of £332 from April's cap of £1,641.
The Iran war has seen global oil and gas prices rise rapidly, as the Strait of Hormuz in the Gulf has been effectively closed by the threat of Iranian strikes.
Around 20% of the world's oil and liquefied natural gas supplies typically pass through the Strait.
Meanwhile, economists are predicting inflation could rise to as high as 5% this year - it was previously expected to fall back to the 2% target before the war.
Interest rates could also increase.
'No need to ration fuel', cabinet minister tells Sky News
Speaking to Sky News on Sunday, Housing Secretary Steve Reed rejected suggestions the UK would run out of fuel amid the ongoing conflict.
"There's no need to ration fuel," Mr Reed told Sunday Morning with Trevor Phillips.
Mr Reed added that while "there's always a contingency plan" for fuel supplies, right now it is not needed.
"People should go around and buy their fuel just like they always would. If the situation were to change, then the government would look at what was required in that circumstance," he said.
"We did intervene when it came to heating oil because we saw the prices escalating and people were seeing their bills doubling and tripling overnight. We can't have that. So we stepped in to support people."
The government previously announced a £53m support package for the poorest users of heating oil last Monday, which is not covered by the price cap.
Our people and politics correspondent Nick Martin says that during fuel crises, perception can become reality.
He says the government is striking a delicate balance between sounding credible, but calm enough to avoid triggering panic.
Panic buying over fears of shortages in both 2021 and 2000 caused fuel to run out at many forecourts - despite there being no actual shortage of fuel then. Instead, there were issues with lorry drivers.
Conservative Sir James Cleverly told Trevor Phillips that the government should respond to the crisis by cancelling planned increases in fuel duty, and by opening up new oil and gas fields in the North Sea.
PC Bradley Corke, 27, died on Saturday, after he was critically injured in Farningham on Thursday evening.
He and a colleague, who remains critically ill in hospital, were responding to an "immediate" call when their marked police car was involved in the crash.
A member of the public who was in a second vehicle continues to be treated for serious injuries.
"Bradley selflessly gave up his life while trying to save the lives of others who were in danger," Kent Police said.
"His bravery, dedication, and passion for helping others will not be forgotten."
The incident, involving a marked Ford Focus police car and a VW Scirocco, happened on the westbound A20 London Road at the junction with Button Street at around 7.45pm on Thursday.
PC Corke served with the force since May 2022. He was based in Tonbridge and spent his police service in the towns of West Kent. The force is supporting his family and colleagues, who are devastated.
Neil Mennie, chair of Kent Police Federation, said: "We are all absolutely heartbroken to learn of this news.
"Bradley was a popular colleague who will be much missed and we will be doing all we can to support his family and close colleagues at this time.
"Policing is a family and words cannot describe the pain we are all feeling and how this news will affect us in the days, weeks and months ahead.
"This sad incident serves as a horrific example of the risks police officers face and how police officers can sadly make the ultimate sacrifice as they strive to keep the public safe."

A spokesperson for the Independent Office for Police Conduct (IOPC) said it would assess a mandatory referral from Kent Police.
The spokesperson said: "Our thoughts are with all those affected by this tragic incident.
"We received a mandatory referral from Kent Police on Friday afternoon, which we will assess in due course before deciding whether any further action is required from us."
Kent Police is appealing for anyone with information about the collision to come forward.
Witnesses or anyone with dashcam footage should contact the serious collision investigation unit.
They can also reach the unit on 01622 798538, quoting EW/AL/025/26.
The US president shared the video on his Truth Social platform and did not include any comment alongside the post.
The skit opened the new UK version of the hit American comedy show, and started with the prime minister, played by George Fouracres, in Downing Street with his deputy David Lammy (Hammed Animashaun).
The fake Sir Keir panicked as he tried to dodge a phone call from Mr Trump and said: "Oh golly - what if Donald shouts at me?"
The prime minister later hung up on the US leader and said: "Oh sod that scary, scary, wonderful president. Why is he so bloody difficult to talk to?"
Sir Keir added: "I just want to keep him happy, Lammy. You don't understand him like I do - I can change him."
The sketch on Sky One also referenced Mr Trump calling Sir Keir a "coward" before introducing his new "Gen Z" adviser played by Jack Shep, who was called Starmzy as a play on the name of hit rapper Stormzy.
Saturday Night Live UK's opening show has been greeted with cautious but generally positive reviews.
The US version of SNL, broadcast in America on NBC, is a pop culture institution which has been running for 50 years, and launched the careers of stars including Bill Murray, Tina Fey, Eddie Murphy, Pete Davidson, Kristen Wiig and Will Ferrell.
While expectations have been high at Sky HQ that a UK version of the format will be successful, others have pointed out the challenges of creating new event TV in such a fragmented media world.
But according to Steve Bennett, writing for the British comedy website Chortle, the SNL UK debut has delivered. "Whisper it, but I think they might just have nailed it," he writes.
"[The show has] been greeted with either feverish excitement that it could instantly become as successful as its parent, reviving British sketch comedy at a stroke, or aggressive pessimism that it'll be shit - an unwelcome transatlantic invasion that couldn't possibly work with our more cynical sense of humour.
"Neither is absolutely true but tonight's episode, a very strong opener, offers great hope it's the former."
The show was seen by 226,000 viewers in its 10pm slot on Sky One and won a 3.2% share of the available TV audience at the time, according to official BARB figures reported on the Deadline website.

Elsewhere, the Independent's Nick Hilton gave the debut three stars out of five, for "some hits, some misses, and a bang-on Princess Di impression".
"Judging a show like SNL off its opening episode is foolish", he writes, before adding: "What SNL UK's opening episode does demonstrate is a willingness to push the envelope, to risk bad taste.
"Borrowing a beloved American format might feel a bit stale, but there are notes of new ingredients that could offer something fresh."
Giving the same score, The Guardian's Lucy Mangan said that SNL UK's debut "didn't fail and it could have been a lot worse".
She added: "The general feeling, I think, will be that the inaugural episode of Saturday Night Live UK - Sky's version of the famous 51-year-old American original founded and still overseen by the infamous Lorne Michaels - did work."
"It could have been a lot, lot worse", she added. "And it could have been a lot better... honestly - it felt refreshing to see an ambition/piece of madness like retooling a legacy US brand for this septic isle even being attempted."
However, she did say one sketch was "an absolute piece of rubbish".

UK not being drawn into Iran war, government insists
In The Sunday Times Charlotte Ivers was pleased that the show did not shy away from edgier humour, writing: "There's something quite refreshing about seeing TV comedians really push close to the line."
But, she added, "sadly, in many cases the jokes don't live up to the risk".
Some of the most positive - if not faint - praise came from The Daily Telegraph's Ed Power's four-star review, who gave credit to guest host Ms Fey and the "shockingly competent" debut.
"Funny in places and never actively harmful to your emotional well-being, it went about as well as could be hoped", he added.
"The only glaring issue was what sounded like deafening canned laughter throughout. If the chuckles genuinely were artificial, then it was surely overkill on the part of the producers.
"Against all reasonable expectations, this homegrown Saturday Night Live was more than capable of raising real laughs on its own."
Before the UK version aired on Saturday, Sky confirmed another two episodes had been commissioned, extending its run to eight shows
Saturday Night Live UK will return on Sky and Now on 28 March, hosted by Jamie Dornan and featuring band Wolf Alice. It will stream on Peacock in the US the following night.
The crowd abuse, during the second half, was reported to have been directed at Sunderland's Lutsharel Geertruida, the league's statement said.
It said the stoppage was "in line with the Premier League's on-field anti-discrimination protocol" and the incident at St James' Park in Newcastle would now be fully investigated.
"We offer our full support to the player and both clubs," the Premier League said. "Racism has no place in our game, or anywhere in society.
"We will continue to work with stakeholders and authorities to ensure our stadiums are an inclusive and welcoming environment for all."

There had been tense scenes between fans outside the stadium before the match, which Sunderland won 2-1 thanks to a late goal by Brian Brobbey.
Newcastle boss Eddie Howe also commented on the incident post-match, telling Sky Sports: "Certainly, we don't condone any form of racism and it's something the club will investigate."
A spokesperson at Newcastle United said: "We are aware of a report of racism made by a visiting player against someone in the crowd during our Premier League match against Sunderland.
"Our stance is clear - we do not tolerate discrimination of any form.
"We will work with the authorities to fully investigate and will ensure any individuals are identified and held accountable."
In a statement, Sunderland said: "We stand with Lutsharel [Geertruida], who has our complete backing, and we commend him for displaying bravery and leadership by reporting this incident to the match officials.
"Racism is completely unacceptable. It is abhorrent, and has no place in our game or in society. We acknowledge Newcastle United's statement and expect those responsible to be identified and held accountable."

Following the game, Chief Superintendent Mark Hall of Northumbria Police said the force was aware of videos showing opposing fans "goading one another ahead of kick-off" and three arrests were made.
He continued: "We also became aware of a report of discriminatory abuse, and as a Force we condemn all forms of discrimination and will always look to take swift and appropriate action against offenders."
With respect to the game, the 2-1 win for Sunderland means they leapfrog Newcastle in the Premier League table.
It also sees them set a new record with 11 Premier League Tyne-Wear derbies unbeaten.
He is one of two officers at Greater Manchester Police who have been specially trained to find the platforms, forums and sites being used by criminals to sell drugs.
"It's effectively run like a legitimate business in the way that Amazon sells legitimate items," he says.
"The platforms that are being used, it's Snapchat and Telegram, we see a lot of stuff on WhatsApp, basically in an attempt to avoid traditional policing tactics."
What the social media investigator describes is a game of cat and mouse, driven by a Class B drug that is being taken in record numbers.
"It's basically trying to catch up with criminals. If you put it in terms of cars, criminals are driving around in sports cars and things like that," he says.
"Police are driving round in Fiestas and Astras, and this is exactly the same thing. But we only have to be lucky one day, they have to be lucky every day."
Against the backdrop of increasing media coverage and greater public awareness of ketamine, the popular party drug is now firmly in the sights of police forces across the country, including GMP.
Detective Superintendent Joseph Harrop, who leads the force's serious organised crime division, says ketamine is presenting officers with unique challenges.
"I think one of the issues is that it's readily available and it's really cheap, which is why I think it's attractive to children and young people," he says.
"There is a worrying trend that younger and younger children are using it. We've got children as young as 10, either with ketamine or involved in the supply of ketamine."

Could ketamine be used to treat depression?
DSI Harrop says another way organised crime groups are making a profit from ketamine is by exporting the drug to countries where it is more tightly regulated or less easily available.
He says GMP seized 50kg of ketamine in the financial year before last, a figure he believes increased substantially in 2025, because his officers made the substance more of a priority.
In his words, ketamine seizures went up "exponentially", while there was also a "massive rise" in the amount of intelligence the force has collected on the drug.
"One of the big challenges is because you've not got that traditional street supply," he adds.
"So that does impact on some of our intelligence streams. It is all online, so there's a sense of anonymity, and you've kind of got to get behind another layer before you can see who's truly involved, but we've adapted to that."
Online menus and faceless transactions
The social media investigator I spoke to is a core part of GMP's attempts to adapt to the challenges ketamine poses.
He spends time trying to trace the online stores being set up on social media by drug dealers. The criminals curate menus, ask for reviews and even offer people perks, like free sweets being delivered along with their drugs.
Ketamine, he says, is often sold alongside other popular party drugs like cocaine and MDMA, in varying strengths and quantities. The purchases are often made using what he calls "faceless" transactions involving cryptocurrency, while the drugs are often delivered in the post, rather than by a courier.
Once the investigator tracks down an account, he flags their content, in the hope that the tech giants who own the platforms will act quickly.
"Some companies are brilliant," he says. "Within 24 hours they'll get back to me and go, you know what? We agree and they'll remove that account.
"Other companies, if they don't see that perceived risk or that account as being a problem, they'll just say, 'thanks, but we'll leave it'. They will let that account continue."
If there is enough evidence, information found online can lead to warrants being carried out on the ground.
During a nationwide county lines week of action, I joined GMP officers on a dawn raid in Salford.
The operation targeted a county line involving the supply and distribution of popular party drugs like ketamine, cannabis, cocaine and MDMA.
Once officers had stormed a flat, they made two arrests, leading a pair of men into a van that was waiting outside.
The officer in charge of the warrant on the day said party drugs are an increasing issue in the area, which is popular among young professionals and students.
"There are multiple people that are known to us, continuously supplying drugs. We're working hard to disrupt this criminality, executing lots of warrants and getting these guys inside and remanded," he said.
"So with ketamine, it's a drug well-used by students, so the younger target market here is rife."
'You can't arrest your way out of people using drugs'
The drugs being seized aren't just leading to convictions and custodial sentences. In another element of GMP's drugs strategy, there is a focus on not just enforcement but harm reduction too.
GMP works closely with Manchester Drug Analysis and Knowledge Exchange (Mandrake), England's first publicly-funded permanent, city-centre based testing and harm reduction facility.
The samples seized by officers on the raids are sent to the Mandrake testing facility at Manchester Metropolitan University so the team there can check exactly what's in circulation on the illegal drugs market.
That information is then shared with the police, council and health bodies, so they can issue public warnings.
Dr Oliver Sutcliffe, who leads the team at the facility, says that of the 600-700 samples they received for testing in the last 12 months, ketamine is "about the second or third" most seized sample.
In the week we filmed with Dr Sutcliffe, Mandrake issued a public health warning about ketamine being contaminated with medetomidine, a high-strength sedative used by vets on large animals.
Dr Sutcliffe showed me three samples of ketamine that all look the same, but were actually of different purities. One of them contained medetomidine.
"It's an anaesthetic and if you combine that with another aesthetic, then what you get is a synergistic effect. So that enhances the sedation," he said.
"And that potentially might put you in positions where if you're more sedated, you might have an accident."
Pointing to the three samples, he said: "If you just visually look at the crystals, they are exactly the same, so from a user's point of view, you would not necessarily be able to tell the difference."
The route a sample takes from a crime scene to Dr Sutcliffe's lab is perhaps the biggest example of how the police are being forced to change course with a drug like ketamine, which is now so commonplace.
DSI Harrop explained how GMP is trying to police the drug differently.
He said: "There was a near-fatal overdose yesterday, where some powder was recovered. The people with the individual who is currently in hospital have suggested she may have taken ketamine.
"We found some powder, but rather than look to do any kind of prosecution, which I think to some extent is fairly futile, I spoke to the Manchester Met (Manchester Metropolitan University) panel last night and they're going to test those for us."
"You can't arrest your way out of people using drugs," he added.
