Brits are said to be enquiring about nuclear bunkers with over 20 bidding for one shelter in the Norfolk countryside amid fears of a Russian attack on UK soil.
Vladimir Putin has recently sent a chilling warning that he would not shy away from going nuclear, insisting "this is not a bluff".
His words have prompted Russians to gather their own equipment so they can build nuclear bunkers to protect themselves from an onslaught.
And it appears President Putin's remarks have concerned UK citizens, with a number of people looking up areas they could escape to should Russia escalate.
Nearly 200 worried Brits enquired about buying a nuclear bunker in the Norfolk countryside in three days, the Daily Star report s.
The bunker, which is located in Brundall and was listed for £25,000 back in March, had over 20 different bidders.
Russ McLean, owner of Unique Property Bulletin, a website which helps sell less common properties, said he believes the interest was down to Putin's actions in Ukraine.
"People are very worried and scared," he said.
"I don't like seeing people in distress. Normally you can fix things, but this is not an easy fix."
He claims to have fielded more than 3,300 calls, emails and texts from terrified Brits. For context, in 2021 his website had 20 enquiries about bunkers over the course of the whole year.
"People are scared and just want to protect their families," Mr McLean said.
Another similar bunker, also in Brundall and built in 1961 at the height of the cold war, sold recently.
The structure was cast in a continuous process as one solid piece of steel reinforced concrete so that it could move in the ground as one if it were subject to the shockwave from a nearby nuclear burst, according to a listing.
It is one of 1,560 similar bunkers constructed in a massive programme which began in the 1950s, according Unique Property Bulletin.
Another listing, for a bunker in Quadring Eaudike, Lincolnshire, gained interest "given what Vladimir Putin is up to at this time," the aforementioned site stated.
And despite not buying a bunker just yet, David Clett, from Kidderminster, says he is keeping tabs on developments.
"I have been a prepper since the Cuban Missile Crisis - the most terrifying day of my life," he said.
"Since then I always watch the way things are going. When Putin invaded Ukraine I drew up a five point plan. At the moment we are between stage II and III.
"This means I am not yet committing to an all-out nuclear war."
But another Brit, from Burnley, Lancashire, said "s*** is going to hit the fan," and he is even considering opening a prepping shop to feed the imminent demand for survival gear.
"With military experience stemming from the 1980s and six years in law enforcement I am in the process of opening a new preppers shop," he told us.
"My wife, an ex Army nurse with vast experience in the NHS, is well aware that her experience is going to be called up on when the system collapses. For me the writing is on the wall... it's not a question of if but when the s*** is going to hit the fan."
And Janny Holtham, from Peterborough, Cambridgeshire, said she has prepared for nuclear war by buying a camping stove and gas, a life water straw and a food dehydrator.
"So much more to buy but you have to start somewhere," she added.
On Tuesday, it was reported that Britain's defence secretary Ben Wallace flew to the US for urgent summits amid the tense concersations over nuclear warfare.
The day before, NATO began its annual nuclear exercises in northwestern Europe, using jets capable of carrying nuclear warheads.
Meanwhile, Russia's war chief - dubbed 'General Armageddon' - issued a deluded rant about his troops retreating in frontline Ukraine - claiming he is helping to save lives.
In a startling outburst, Col Gen Sergei Surovikin made a string of ludicrous claims about Ukraine’s forces - bizarrely reversing accusations leveled against Moscow’s bungling invasion force.
As more Moscow cruise missiles and Iran-made drones slammed into civilian areas on Wednesday, the Chechnya war veteran whined about Ukrainian resilience.
It came as Putin slapped martial law on four regions of Ukraine he has illegally annexed in a nobbled and illegal poll.
