The bleak official figures came as the British government seeks to win more time to secure EU concessions on Brexit that could pass parliament and avert a chaotic split from the bloc on March 29.
Businesses are on edge with Britain just weeks away from its scheduled departure from the European project after 46 years and still with no firm arrangements in place.
The UK parliament last month roundly rejected a Brexit deal Prime Minister Theresa May had sealed with the remaining 27 EU leaders.
Monday's figures followed data last week that showed Britain's dominant service sector almost ground to a halt in January.
"The economy is clearly struggling in the first quarter of 2019 amid serious business and consumer caution resulting from heightened Brexit uncertainties while weaker global growth is also impacting" the figures, noted Howard Archer, chief economic advisor at the EY ITEM Club.
Last year gross domestic product growth stood at 1.4%, down from 1.8% in 2017, the Office for National Statistics said Monday.
Growth was meanwhile only 0.2% in the last 3 months of 2018, the ONS said in a statement.
"Construction, production and services output fell in the month (of December), the first time that there has been such a broad-based fall in monthly output since September 2012," the ONS said.
Britain has been in a state of political turmoil for two months since the Brexit deal was agreed in December.
In an incident heavy with symbolism, parts of parliament were cordoned off Monday after a large piece of masonry fell onto a parked vehicle over the weekend.
600,000 jobs under threat
Meanwhile in Luxembourg the EU's chief Brexit negotiator Michel Barnier called for "clarity and movement" from Britain.
He also said British opposition leader Jeremy Corbyn's proposal for a permanent customs union with the EU was an "interesting" one.
Concern is growing on both sides of the Channel.
Researchers at the IWH Institute in Halle, eastern Germany on Monday said a no-deal Brexit could put 600,000 jobs around the world at risk, with Germany the hardest hit.
The institute examined what would happen if UK imports from the remaining EU fell 25% after Brexit.
They reckoned some 103,000 jobs would be under threat in Germany, Europe's largest economy, with the car industry the worst affected sector.
Global growth slowdown
Monday's economic data came after the Bank of England last week slashed its forecast for UK growth this year to 1.2% from 1.7%, blaming the downgrade on a global economic slowdown and "the fog of Brexit."
The Bank of England last week warned that Britain's economic output was also being dragged down by a global slowdown, with growth dampening in China, the United States and eurozone.
The point was echoed by analysts reacting to Monday's data.
"Brexit uncertainty is certainly not helping matters on the economic front, but it is probably only a secondary factor in this slowdown, with the primary cause being a drop in overall global activity," noted David Cheetham, chief market analyst at XTB trading group.
The pound, the main indicator of Britain's economic health, fell against the euro and dollar in reaction to Monday's growth data.
London's benchmark FTSE 100 stocks index, which features many multinationals, was however higher on hopes of a breakthrough in US-China trade talks.
"Sterling was knocked off course again as a weak GDP print confirmed the slowdown in the economy," said Neil Wilson, chief market analyst at Markets.com.
"We must caution against blaming all on Brexit – global cooling is having the biggest dampening effect on all major economies at present – although we must note that (UK) business investment is collapsing," he added. – Rappler.com
