In 2014, relations soured drastically following the Ukrainian crisis, with the British government, along with the US and the EU, imposing punitive sanctions on Russia.
In March 2014, The UK suspended all military cooperation with Russia and halted all extant licences for direct military export to Russia.
In September 2014, there were more rounds of sanctions imposed by the EU, targeted at Russian banking and oil industries, and at high officials.
Russia responded by cutting off food imports from the UK and other countries imposing sanctions.
David Cameron, the UK prime minister (2010–2016), and U.S. president Obama jointly wrote for The Times in early September: ″Russia has ripped up the rulebook with its illegal, self-declared annexation of Crimea and its troops on Ukrainian soil threatening and undermining a sovereign nation state″.
In early 2017, during her meeting with U.S. president Donald Trump, the UK prime minister Theresa May appeared to take a line harsher than that of the U.S. on the Russian sanctions.

In April 2017, Moscow's ambassador to the UK Alexander Yakovenko said UK-Russia relations were at an all-time low.

In mid-November 2017, in her Guildhall speech at the Lord Mayor's Banquet, prime minister May called Russia ″chief among those today, of course″ who sought to undermine the ″open economies and free societies″ Britain was committed to, according to her.
She went on to elaborate: ″[Russia] is seeking to weaponise information.
Deploying its state-run media organisations to plant fake stories and photo-shopped images in an attempt to sow discord in the West and undermine our institutions.
So I have a very simple message for Russia.
We know what you are doing.
And you will not succeed.″ In response, Russian parliamentarians said Theresa May was "making a fool of herself" with a "counterproductive" speech; Russia's embassy reacted to the speech by posting a photograph of her from the Banquet drinking a glass of wine, with the tweet: "Dear Theresa, we hope, one day you will try Crimean #Massandra red wine".
Theresa May's Banquet speech was compared by some Russian commentators to Winston Churchill's speech in Fulton in March 1946; it was hailed by Andrew Rosenthal in a front-page article run by The New York Times that contrasted May's message against some statements about Putin made by Donald Trump, who, according to Rosenthal, ″far from denouncing Putin's continuous assaults on human rights and free speech in Russia, [...] praised [Putin] as being a better leader than Obama.″
In December 2017 Boris Johnson became the first UK foreign secretary to visit Russia in 5 years.

In March 2018, as a result of the poisoning of Sergei and Yulia Skripal in Salisbury, relations between the countries deteriorated still further, both countries expelling 23 diplomats each and taking other punitive measures against one another.
Within days of the incident, the UK government's assessment that it was ″highly likely″ that the Russian state was responsible for the incident received the backing of the EU, the US, and Britain's other allies.
In what the Foreign Secretary Boris Johnson called the "extraordinary international response" on the part of the UK's allies, on 26 and 27 March 2018 there followed a concerted action by the U.S., most of the EU member states, Albania, Australia, Canada, Macedonia, Moldova, and Norway, as well as NATO to expel a total of over 140 Russian accredited diplomats (including those expelled by the UK).

Additionally, in July 2018, the COBR committee were assembled following a poisoning of two other British citizens in the town of Amesbury, not far from Salisbury, the location of the Skripals' poisoning.
It was later confirmed by Porton Down that the substance was a Novichok agent.
Sajid Javid, the United Kingdom's home secretary insisted in the house of commons that he was letting the investigation teams conduct a full investigation into what had happened before jumping to a major conclusion.
He then re-iterated the initial question to Russia regarding the Novichok agent, accusing them of using the
