According to the poll, only 21 percent of respondents expressed support for the controversial shale gas extracting technique, the lowest level since the agency first surveyed Britons on the issue in December 2013.
A total of 28 percent opposed fracking, which is "a reversal of the findings when these questions were first asked [in December 2013], when 27% supported it against 21% that opposed it," the poll revealed.
Almost half of the public — 46 percent — said they neither supported nor opposed fracking.
Fracking, or hydraulic fracturing, is a technique used to extract shale gas and oil by injecting a mixture of chemicals into the ground at high pressure.
Environmentalists strongly criticize the technique, arguing that it exposes the environment to the risk of leakages and spillages of poisonous liquid materials and fracking fluids making their way into groundwater supplies.
In 2011, hydraulic fracturing in Lancashire caused two earth tremors, leading to a temporary fracking ban in the United Kingdom that was lifted the following year.
